Description

  The present invention relates to a humidifier, a control method for the humidifier, and an air conditioner having the humidifier, and particularly suppresses the occurrence of condensation in the humidified air side air passage.

2. Description of the Related Art Conventionally, an air conditioner having a humidifying function is one in which moisture is adsorbed from outside air to an adsorbent outside the room, and then humidified air is released from the adsorbent and humidified and supplied to the room through a pipe. .
As a first conventional technique, for example, “... in an air conditioner having a humidifying function, the setting means (45) for setting the length of the humidifying hose (4) and the setting means (45) are set. The humidification hose (4) is controlled such that the longer the humidification hose (4) is, the shorter the humidification operation time is, while the longer the humidification hose (4) is, the longer the drying operation time is. An air conditioner having a humidifying function characterized by comprising a humidifying operation control means (44) "is known (for example, see Patent Document 1).

  Further, as a second conventional technique, for example, “a humidifying unit (20) that is installed outside and generates humidifying air, and an air duct that opens into the room and guides the humidifying air from the humidifying unit (20) to the room ( 21) and a humidifying device for humidifying the room by sending humid air into the room, the humidifying unit (20) having a heating means (26) for heating the air, and the heating means (26 ) Is known to supply moisture to the air heated in step (1) and generate humidified air in a predetermined state so that the humidified air becomes saturated air at least in the middle of the air duct (21). (For example, refer to Patent Document 2).

Japanese Patent No. 3402281 (Claims, FIG. 4, Table 1) Japanese Patent No. 3438672 (Claims, FIG. 2)

  The first prior art has a problem that the humidifying performance is lowered because humidification is not performed during the drying operation. In particular, when the humidifying hose is long or when the outside air temperature is low, the drying operation time is set longer than the humidifying operation time, so that there is a problem that only less than half of the humidifying performance of the humidifying rotor can be used.

  The second prior art has a problem that condensation occurs in the air path on the humidified air side. As a means of solving condensation, a method of draining the condensed water by installing a drainage unit has been adopted.For example, the drainage unit is accurately placed at the lowest point of the air duct due to the installation position or the convenience of the contractor. If it cannot be installed, the condensed water cannot be drained. In addition, as a problem related to condensation, abnormal noise may be generated in the condensation process of saturated air due to contact between the condensed water and the carrier air.

  The present invention has been made in order to solve the above-described problems, so that the humidification performance of the moisture adsorbing means does not deteriorate even if the humidification process continues to be operated, and the origin of occurrence of abnormal noise and installation restrictions. An object of the present invention is to provide a humidifier that can be operated by controlling the amount of humidification so as not to cause dew condensation.

  A humidifier according to the present invention includes a moisture adsorbing means divided into a first area and a second area by an air passage partition plate, a heating means for generating high-temperature air to be sent to the moisture adsorbing means, and outdoor air for sucking outdoor air First air blowing means for exhausting air, second air blowing means for sucking outdoor air and supplying the air into the room, the first air blowing means communicating with the first area, and the second air blowing means being the second area. A first pattern that communicates; and an air path switching damper that switches between the second pattern in which the first blowing unit communicates with the second region and the second blowing unit communicates with the first region. When the air path switching damper is switched, the control value of the heating means is set to an initial control value smaller than the target control value of the heating means, and within a predetermined period from the switching time. , Stepping the control value from the initial control value Or continuously so as to be greater, after the predetermined period of time is one that has a control means for setting the control value to the target control value.

  In the present invention, by controlling the humidification amount for air to a value smaller than a predetermined target value, the relative humidity of the humidified air is suppressed to 100% or less, and the occurrence of condensation on the air path on the humidified air side is effective. Can be suppressed.

An AC power supply 54a supplies power, and a resistance switching device 54b changes a resistance value (control value) of the heating means 4 by changing a switch connected to the heating means 4, thereby changing a heating amount of the heating means 4. It is. The control unit 50 controls the air path switching damper rotation motor 55 according to the time set in the memory 51 in advance, and rotates the first air path switching damper 5 and the second air path switching damper 6 so that the air path A and Switch to air path B.

FIG. 3 is an internal perspective view of dehumidifying / humidifying device C according to Embodiment 1 of the present invention.
FIG. 1 shows a state in which the rotating shafts 102 of the first air path switching damper 5 and the second air path switching damper 6 are oriented in the horizontal direction, but FIG. 3 shows the state in which the rotating shaft 102 is oriented in the vertical direction. is there.
In FIG. 3, the intake air A <b> 0 is sucked as it is from the first intake port 42 as the adsorption inlet air A <b> 1 by the first blower 2 via the adsorption air inlet 103. The adsorption inlet air A1 flows upward, and moisture in the outside air is adsorbed when passing through the moisture adsorption means 1 to become dry air. After becoming dry air, it flows out from the 1st exhaust port 12 as adsorption exit air A2, and is exhausted from the adsorption air exit 104 to the exterior.

  The intake air A0 is heated by the heating means 4 via the regeneration air inlet 105 to become high-temperature and low-humidity air, and then sucked from the second intake port 13 as regeneration inlet air B1. The regeneration inlet air B1 flows downward, and when it passes through the moisture adsorption means 1, the moisture adsorbed on the moisture adsorption means 1 is regenerated to become high-humidity air. After becoming high-humidity air, it flows out as regeneration outlet air B2 from the second exhaust port 43, passes through the second air blowing means 3, passes through the regeneration air outlet 106, is transported into the room, and humidifies the room.

4 is a detailed view of the air path configuration around the moisture adsorbing means 1 inside the humidifying unit 100 in the schematic structural diagram of the dehumidifying / humidifying device shown in FIG.
Although each part is disassembled and shown in an easy-to-understand manner, the parts that are adjacent in the vertical direction are actually in close contact with each other.

  The peripheral air path of the moisture adsorbing means 1 has a total of four layers including an upper two layers (first layer 10 and second layer 20) and a lower two layers (third layer 30 and fourth layer 40) across the moisture adsorbing means 1. The first layer 10 is the first air channel partition plate 11, the second layer 20 is the second air channel partition plate 21, the third layer 30 is the third air channel partition plate 31, and the fourth layer 40 is Each of the air paths is divided into two by the fourth air path partition plate 41. At this time, the 2nd airway partition plate 21 and the 3rd airway partition plate 31 are parallel, and are each closely_contact | adhered and installed in the water | moisture-content adsorption | suction means 1, and with respect to these, the 1st airway partition plate 11 and the 4th wind The road partition plate 41 is installed vertically. Therefore, the second layer 20, the moisture adsorption means 1 and the third layer 30 are divided into two air paths in the same direction, and the first layer 10 and the fourth layer 40 are divided into two air paths in the direction perpendicular to them. Will be.

  Between the first layer 10 and the second layer 20 and between the third layer 30 and the fourth layer 40, there are two sectors (1/4 circle) having a central angle of 90 ° as shown in FIG. Dampers connected in a diagonal direction at 1, that is, a first air path switching damper 5 and a second air path switching damper 6 are installed. And both fan-shaped parts are installed so that it may become alternate. Thereby, the diagonal 2 area | region is made into the 1st air path switching damper 5 among 4 area | regions of the 1/4 circle | round | yen by the side of the upper air path formed by the 1st air path partition plate 11 and the 2nd air path partition plate 21. FIG. Is blocked. On the other hand, among the four regions each formed by the third airway partition plate 31 and the fourth airway partition plate 41 each having a quarter circle on the lower airway side, the diagonal two regions that are 90 ° different from the upper part are second The air path switching damper 6 is closed.

  Further, in the first layer 10, of the two air paths divided by the first air path partition plate 11, the first exhaust port 12 and the second air blowing means 3 communicate with the air path side communicating with the first air blowing means 2. A second air inlet 13 is provided on the air path side. Similarly, in the fourth layer 40, of the two air paths divided by the fourth air path partition plate 41, the first air inlet 42 and the second air blowing means 3 communicate with the air path side communicating with the first air blowing means 2. A second exhaust port 43 is installed on the air path side.

  Here, the first air passage partition plate 11, the second air passage partition plate 21, the third air passage partition plate 31, and the fourth air passage partition plate 41 have circular air passages on the partition surface of each air passage partition plate. A protrusion 11a, a protrusion 21a, a protrusion 31a, and a protrusion 41a are provided on the entire radial direction in a direction perpendicular to the partition surface. In addition, an upper protrusion 5 a is provided in the direction of the first air path partition plate 11 and a lower protrusion 5 b is provided in the direction of the second air path partition plate 21 on the entire sector radius portion of the first air path switching damper 5. Similarly, an upper protrusion 6 a in the direction of the third air path partition plate 31 and a lower protrusion 6 b in the direction of the fourth air path partition plate 41 are provided on the entire sector radius portion of the second air path switching damper 6. .

  FIG. 5 shows a view of the contact portions of the first air path partition plate 11, the second air path partition plate 21, and the first air path switching damper 5 as seen from the direction of the black arrow shown in FIG. As shown in FIG. 5, the installation position of the projection 11 a of the first air path partition plate and the height of the upper projection 5 a of the first air path switching damper coincide with each other, and the first air path partition plate 11. And the upper projection 5a of the first air path switching damper are engaged with each other.

  Similarly, the installation position of the projection 21 of the second air path partition plate and the height of the lower projection 5b of the first air path switching damper are the same, and the partition surface of the second air path partition plate 21 and the projection 21a The lower projection 5b of the first air path switching damper is engaged. Although not shown here, the positional relationship between the protrusion 31a of the third air passage partition plate and the protrusion 41a of the fourth air passage partition plate and the upper protrusion 6a and the lower protrusion 6b of the second air passage switching damper are the same. .

Next, an example of the operation in the first embodiment will be described with reference to FIG.
FIG. 6 is a plan view of each layer shown in FIG. The left damper position <A> in FIG. 6 is the same as the damper position in FIG.

  At the damper position <A>, the suction air A0 is sucked as it is as the suction inlet air A1 from the first suction port 42 by the first air blowing means 2 via the suction air inlet 103 shown in FIG. And since it flows into the area | region 40a of the 4th layer 40 partitioned off by the 4th air path partition plate 41 shown in FIG. 6, and the area | region 6a is obstruct | occluded by the 2nd air path switching damper 6, it is 3rd from the area | region 6b. Flows into the layer 30. The third layer 30 is partitioned into a third air passage partition plate 31 and the second layer 20 is partitioned into a semicircle by a second air passage partition plate 21, and the moisture adsorbing means 1 sandwiched between the two layers is also included. Since it is divided in the same manner, the air flowing in from the region 6b flows upward in the order of the region 30b, the region 1b, and the region 20b, and moisture in the outside air is adsorbed when passing through the region 1b to become dry air.

  After becoming dry air, since the area 5b is closed by the first air path switching damper 5, it flows into the area 10b of the first layer 10 partitioned by the first air path partition plate 11 from the area 5d, and then It flows out as the adsorption outlet air A2 from the first exhaust port 12, and is exhausted to the outside from the adsorption air outlet 104 shown in FIG.

  On the other hand, the intake air A0 shown in FIG. 3 is heated by the heating means 4 through the regeneration air inlet 105 to become high-temperature and low-humidity air, and thereafter, the regeneration inlet air B1 shown in FIG. Sucked from. The regeneration inlet air B1 flows into the region 10a of the first layer 10 partitioned by the first air path partition plate 11. The air that has flowed in flows into the second layer 20 from the region 5 a because the region 5 b is closed by the first air path switching damper 5. The second layer 20 is partitioned into a second air passage partition plate 21 and the third layer 30 is divided into a semicircle by a third air passage partition plate 31, and the moisture adsorbing means 1 sandwiched between the two layers is also included. Since it is divided in the same manner, the high-temperature and low-humidity air flowing from the region 5a flows downward in the order of the region 20a, the region 1a, and the region 30a, and the moisture adsorbed by the moisture adsorbing means 1 when it passes through the region 1a is regenerated. It becomes high humidity air.

  After becoming the high humidity air, the area 6a is closed by the second air path switching damper 6, and therefore flows from the area 6c into the area 40b of the fourth layer 40 partitioned by the fourth air path partition plate 41, Thereafter, it flows out from the second exhaust port 43 as regeneration outlet air B2. The regeneration outlet air B2 passes through the second air blowing means 3 shown in FIG. 3 and is conveyed into the room through the regeneration air outlet 106 to humidify the room.

Next, after the time for completing the adsorption step in the region 1b and the regeneration step in the region 1a of the moisture adsorption means 1 has elapsed, the damper position shown in FIG. 6 is switched from <A> to <B>.
At this time, the suction air A0 is sucked as it is as the suction inlet air A1 from the first air inlet 42 by the first air blowing means 2 through the suction air inlet 103 and is partitioned by the fourth air passage partition plate 41. Since the region 6b is blocked by the second air path switching damper 6 and enters the region 40a of the layer 40, the air flows into the third layer 30 from the region 6a. The third layer 30 is partitioned into a third air passage partition plate 31 and the second layer 20 is partitioned into a semicircle by a second air passage partition plate 21, and the moisture adsorbing means 1 sandwiched between the two layers is also included. It is divided in the same way. Therefore, the air flowing in from the region 6a flows upward in the order of the region 30a, the region 1a, and the region 20a, and the moisture in the moisture adsorbing means 1 is regenerated and dried when the region 1a is at the damper position <A>. When the region 1a passes, moisture in the air is adsorbed to become dry air.

  After becoming dry air, since the area 5a is closed by the first air path switching damper 5, the air flows into the area 10b of the first layer 10 partitioned by the first air path partition plate 11 from the area 5c. It flows out as the adsorption outlet air A2 from the first exhaust port 12 and is exhausted from the adsorption air outlet 104 to the outside of the room.

  On the other hand, as in the case of the damper position <A>, the regeneration inlet air B1 that has been heated by the heating means 4 to become high-temperature and low-humidity air via the regeneration air inlet 105 via the regeneration air inlet 105 is the second intake port. 13 is sucked in and flows into the region 10 a of the first layer 10 partitioned by the first air passage partition plate 11. The air that has flowed in flows into the second layer 20 from the region 5 b because the region 5 a is closed by the first air path switching damper 5. The second layer 20 is partitioned into a second air passage partition plate 21 and the third layer 30 is divided into a semicircle by a third air passage partition plate 31, and the moisture adsorbing means 1 sandwiched between the two layers is also included. Since it is divided in the same manner, the high-temperature and low-humidity air flowing from the region 5b flows downward in the order of the region 20b, the region 1b, and the region 30b, and the moisture adsorbing means 1 when the damper position is <A> when passing through the region 1b. The moisture adsorbed on the water is regenerated to become highly humid air.

  After becoming high-humidity air, since the area 6b is closed by the second air path switching damper 6, it flows from the area 6d into the area 40b of the fourth layer 40 partitioned by the fourth air path partition plate 41, Thereafter, it flows out from the second exhaust port 43 as regeneration outlet air B2. Then, the regeneration outlet air B2 passes through the second air blowing means 3, passes through the regeneration air outlet 106, is transported into the room, and humidifies the room.

  In this way, it is possible to continuously supply humidified air into the room by a simple operation of rotating the first air path switching damper 5 and the second air path switching damper 6 and switching the air path. Further, since the wind directions in the region 1a and the region 1b of the moisture adsorbing means 1 are opposite, that is, the adsorption process and the regeneration process are counterflows, even if the thickness of the moisture adsorbing means 1 is increased, moisture adsorption and regeneration are efficient. Can be done.

  Here, the optimum value of the time for switching the air path varies depending on the kind of the adsorbent supported on the moisture adsorption means 1, and is short in the case of a material having a relatively high adsorption rate such as zeolite (about 45). In the case of a material with a relatively low adsorption rate such as silica gel, it is possible to set the length long (about 90 to 180 seconds), so that an optimum operation can be performed for an adsorbent having various characteristics. .

  In addition, the damper of the present invention is applied to a rotor system in which an adsorption air passage through which low-temperature air flows and a regeneration air passage through which high-temperature and high-humidity air flows are always fixed, and condensation tends to occur on the regeneration air passage side of the boundary surface between both air passages. In the switching method, the adsorption air passage and the regeneration air passage are switched, and the specific air passage is not cooled.

The difference from the rotor system that rotates the moisture adsorbing means 1 is that the vicinity of the moisture adsorbing means 1 having the largest air leakage is completely sealed by the second air passage partition plate 21 and the third air passage partition plate 31. is there.
Further, as shown in FIG. 5, the first air path switching damper 5 is engaged with the partition surface, the protrusion 11a and the upper protrusion 5a of the first air path partition plate 11, and similarly, the second air path partition plate. The partition surface 21, the protrusion 21 a and the lower protrusion 5 b are also engaged. Compared with the case where the air path switching damper is in contact with the partition plate alone, not only the contact area is increased, but the air path between the air path partition plate and the air path switching damper is L-shaped, and air pressure is lost due to pressure loss. Since it becomes difficult to pass through, air leakage can be suppressed.

  In addition, since there is a protrusion at a position that inhibits the rotation of the air path switching damper, it cannot be rotated in the same direction, and the air path is switched by forward / reverse rotation at an angle of 90 °. Since the protrusion of the damper engages with the partition plate and serves as a stopper, it is possible to completely prevent the rotation error of the air path switching damper. In addition to this, the lower projection 5b of the first air path switching damper and the lower projection 6b of the second air path switching damper are respectively in relation to the projection 21a of the second air path partition plate and the projection 41a of the fourth air path partition plate. Since part of the projection 21a and the projection 41a are always in contact with each other, the projection 21a and the projection 41a also serve as a guide when the air path switching damper rotates, and the effect of preventing the vertical shake can be expected.

FIG. 7 is a conceptual diagram of a dehumidifying / humidifying amount control method according to Embodiment 1 of the present invention.
Graph 60 shows the time series change of the heating means control value (Q) in the power supply means 54, graph 61 shows the time series change of the dehumidification / humidification amount (W), and graph 62 shows the relative humidity (Φ _deo ) of the regeneration outlet air B2. Each series change is shown.

FIG. 7 means that the dehumidifying / humidifying amount (W) and the regeneration outlet air relative humidity (Φ _deo ) change with the change of the heating means control value (Q). The set value 63 is the set value (Q _set ) of the heating means control value, the set value 64 is the set value (W _set ) of the dehumidification / humidification amount, and the heating means control value (Q) is the set value (Q _set ). Thus, the dehumidifying / humidifying device shown in FIGS. 1 and 3 shows that the dehumidifying / humidifying amount (W) of the set value (W _set ) can be obtained.

The control value 65 is a heating means initial control value, which means heating means control value of the damper switching (Q _ini), only at start as a boot heating means initial control value _{65a (Q ini 0), Q} ini It is set a little lower. Similarly the control value 67 is a heating means control value (Q) refers to the control value changing time period for changing the (t _cha), only at start as the starting control value changing time 67a (t _cha 0), It is set slightly longer than t _cha . The control value 68 is a damper switching time (t _dump ) that means an interval for rotating the air path switching damper rotation motor 55, and is previously set so as to be longer than the control value change time (t _cha 0, t _cha ). It is set in the memory 51.

Here, the time-series change of the dehumidification / humidification amount (W) and the regeneration outlet air relative humidity (Φ _deo ) when the heating means control value (Q) is changed will be described based on the actual measurement results.
8 to 10 show the dehumidifying / humidifying apparatus shown in FIGS. 1 and 3, after the moisture in the ambient air is sufficiently adsorbed by the entire moisture adsorbing means 1, the first air path switching damper 5 and the second air path. (A) Dehumidification / humidification amount (W) / set dehumidification / humidification amount (W _set ) and 20 minutes after starting operation when the heating means 4 is operated in a state where the switching damper 6 is fixed without rotating. b) Measured result of time series change of regeneration outlet air relative humidity (Φ _deo ).

FIG. 8 shows the actual measurement results when the ambient air relative humidity is 60% RH, FIG. 9 is 80% RH, and FIG. 10 is 90% RH. Each figure shows a time-series change due to the difference in the heating means control value (Q), and the graphs 69a to 69f are respectively heating means control value (Q) / set heating means control value (Q _set ) = 0. The dehumidifying / humidifying amount (W) / the set dehumidifying / humidifying amount (W _set ) when 2 to 0.8, and similarly, the graph 70a to the graph 70f are the heating means control value (Q) / set heating means control value, respectively. It is a time-series change actual measurement value of the regeneration outlet air relative humidity (Φ _deo ) when (Q _set ) = 0.2 to 0.8. Here, the dehumidifying / humidifying amount (W) actually means the humidifying amount (W _de ) since the moisture adsorbing means 1 is not fixed and newly adsorbed, but the performance is the same.

From the results of FIGS. 8 to 10, the maximum value of the dehumidifying / humidifying amount (W) and the regeneration outlet air relative humidity (Φ _deo ) increases as the heating means control value (Q) increases under any ambient air relative humidity. In addition, there is a tendency to begin to decline earlier in time.
Further, there is a relationship that the dehumidification / humidification amount (W) exceeds the maximum value and the regeneration outlet air relative humidity (Φ _deo ) starts to decrease. If the ambient air relative humidity to be adsorbed is the same, the initial adsorbed moisture amount is the same, but the greater the heating means control value (Q), the lower the relative humidity of the regeneration inlet air B1, so humidification per hour. The total amount of released water, which is obtained by integrating the amount = dehumidification / humidification amount (W) and the dehumidification / humidification amount (W) with the elapsed time (t), also increases.

From the actual measurement results, it is meant that the larger the heating means control value (Q), the greater the total amount of released water, and the faster the initial adsorbed moisture is released. On the other hand, with the same heating means control value (Q), the higher the ambient air relative humidity is, the larger the maximum value of the dehumidification / humidification amount (W) and the regeneration outlet air relative humidity (Φ _deo ) is, and also the temporal decrease is. There is a tendency to slow down. This means that the higher the ambient air relative humidity is, the more the amount of initial adsorbed moisture and the total amount of released moisture are. These tendencies are phenomena that are always observed when shifting from the adsorption process to the regeneration process, and are particularly prominent at the start-up after sufficient adsorption as shown in the actual measurement results.

Based on the above measurement results, an example of the operation of the dehumidification / humidification amount control method shown in FIG. 7 will be described.
In the dehumidifying / humidifying device shown in FIGS. 1 and 3, when the first air path switching damper 5 and the second air path switching damper 6 are rotated and the process proceeds from the adsorption process to the regeneration process as described in FIG. There is a high possibility that the humidification amount (W) and the regeneration outlet air relative humidity (Φ _deo ) increase rapidly as shown in FIGS.

In particular, at the time of start-up when the operation is resumed after being left for a certain period of time, when a dehumidifying / humidifying device is installed in a high-humidity outdoor space such as a standard heating condition (7 ° C./87% RH), for example, FIG. As shown in the graph 70d, even when the heating means control value (Q) is limited to Q / Q _set = 0.4, the regeneration outlet air relative humidity (Φ _deo ) reaches 100% RH, and the regeneration outlet air B2 Will condense.

  Therefore, when the relative humidity of the blown regeneration outlet air B2 increases according to the operation time from the time of switching the air path switching damper 5 and the air path switching damper 6, it does not become 100% RH at any point in time, that is, regeneration. The relationship between the relative humidity, the heating amount, and the air volume of the adsorption inlet air A1 adsorbed by the moisture adsorbing means 1 is set in advance so that condensation does not adhere to the air blowing circuit through which air is blown.

  For example, 1) The heating amount (heating intensity) of the heating means 4 at the time of switching the damper is set to a small value with respect to a predetermined value, and is gradually increased to a predetermined value, and 2) the second blower means 3 is set to a value larger than a predetermined value and the air blowing amount by 3 is gradually reduced to a predetermined value, or 3) the amount of air sucked by the first blowing means 2 is set to a predetermined value. Thus, three methods are conceivable: setting the value to a small value and gradually increasing the value to a predetermined value. It is preferable to preliminarily set the humidification amount of the air when the damper is switched to be small by any one of the above three methods, and then gradually increase the predetermined humidification amount after a predetermined period.

Specifically, as shown in the time series change 60 of the heating means control value (Q) in FIG. 7, when the damper is switched, Q = Q _ini <Q _set is set, and the control value change time (t _cha ) is set. In the meantime, the heating means control value (Q) is raised stepwise and _set to Q = Q _set after t _cha elapses from the damper switching. Then, the dehumidifying / humidifying amount (W) gradually increases and reaches W = W _set after t _cha elapses from the damper switching, as indicated by the time series change 61. The regeneration outlet air relative humidity (Φ _deo ) gradually increases but does not reach 100% RH as indicated by the time series change 62, and decreases after the passage of t _cha. It is possible to operate without causing the air B2 to condense.

In particular, at the time of start-up when the operation is restarted after being left for a certain period of time, the regeneration outlet air relative humidity (Φ _deo ) is more likely to rise than during normal damper switching. is set to low Q _ini 0 than Q _ini, similarly controlled value changing time is set longer t _cha 0 from t _cha. At the same time, during this control value change time (t _cha , t _cha 0), the heating means control value (Q) is lowered below the set value (Q _set ), and wasteful dehumidifying / humidifying operation that causes dew condensation occurs. Therefore, an energy saving effect can be expected with respect to a normal dehumidifying / humidifying operation for continuously obtaining the set dehumidifying / humidifying amount (W _set ).

  Here, as the time series change 60 of the heating means control value (Q), for example, as shown in Table 1, low humidity (FIG. 8: 60% RH) is assumed and standard (FIG. 8) according to the relative humidity of the ambient air. 9: 80% RH) assumption and high humidity (FIG. 10: 90% RH) assumption, the relationship between the time (t) and the heating means control value (Q) is set and incorporated in the memory 51.

In this case, the heating means control value of the damper switching the startup only startup heater initial control value as _{(Q 01 = Q ini 0)} , the heating means initial control value of the normal (Q ₁ = Q _ini) Set low. Similarly, the period during which the heating means control value (Q) is changed is a control value change period (t ₁ ) at the normal time as a start time control value change time (t ₀₁ + t ₀₂ + t ₀₃ = t _cha 0) only at the start. + T ₂ = t _cha ). Also, the higher the relative humidity of the ambient air is assumed, the heating means control value _{(Q 01, Q 02, Q} 03, Q 1, Q 2) is set low, the control value change time (t _01, t ₀₂ , T ₀₃ , t ₁ , t ₂ ) are set long.

The setting method shown in Table 1 is an example, and a setting corresponding to the installation environment, region, or the like may be used. Moreover, in order to completely avoid the condensation of the regeneration outlet air B2, a setting assuming high humidity (90% RH) may always be used. In Table 1, for each humidity assumption, the time t _dump from the start to the first damper switching is divided into four, and thereafter, the heating means control value (Q) is set in three. The number of divisions may be changed depending on the assumption.

起動から時刻ｔ＝０〜ｔ_cha０までは、時間ｔ₀₁、ｔ₀₂及びｔ₀₃に対応して、加熱手段制御値（Ｑ）をＱ₀₁、Ｑ₀₂及びＱ₀₃に設定し、その後時刻ｔ＝ｔ_cha０〜ｔ_dumpの時間ｔ₀₄の間は、Ｑ₀₄＝設定値Ｑ_setに設定する。起動後１回目のダンパ切換終了ｔ＝ｔ_dump以降は、ダンパ切換からｔ_chaの間は、時間ｔ₁及びｔ₂に対応して、加熱手段制御値（Ｑ）をＱ₁及びＱ₂に、ｔ_cha経過後から次のダンパ切換までの時間ｔ₃の間は、Ｑ₃＝設定値Ｑ_setに設定することを繰り返す。

From the time t = 0 to t _cha 0, the heating means control value (Q) is set to Q ₀₁ , Q ₀₂ and Q ₀₃ corresponding to the times t ₀₁ , t ₀₂ and t ₀₃ , and then the time t = T _cha 0 to t _dump time t ₀₄ is _set to Q ₀₄ = set value Q _set . From the end of the first damper switching after startup t = t _dump , the heating means control value (Q) is set to Q ₁ and Q ₂ corresponding to the times t ₁ and t ₂ from the damper switching to t _cha . During the time t ₃ after the time t _cha elapses until the next damper switching, the setting of Q ₃ = set value Q _set is repeated.

8 to 10 and the set value of the time series change 60 of the heating means control value (Q) in Table 1 are based on the regeneration outlet air B2 immediately after being released from the dehumidifying / humidifying device. However, when the dehumidifying / humidifying device is installed outside and the regeneration outlet air B2 is conveyed by a duct or the like to humidify the room, the possibility that the regeneration outlet air B2 is cooled and condensed in the duct conveyance process is increased. _Therefore , the control value change time (t _cha 0, t _cha ) is longer than the values shown in Table 1, and the heating means control values (Q ₀₁ , Q ₀₂ , Q ₀₃ , Q ₁ , Q ₂ ) are set lower. There is a need.

The dehumidifying / humidifying amount control method shown in FIG. 7 is used when the air path switching damper switching time (t _dump )> the control value change time (t _cha 0, t _cha ), and before the damper switching is performed. The heating means control value (Q) is always controlled to reach the _set value (Q _set ), but when t _dump ≦ t _cha 0 or t _dump ≦ t _cha , Q has reached Q _set. Even if not, it is necessary to set Q to the heating means initial control value (Q _ini ). However, this air path switching damper switching time (t _dump ) is for optimizing the operation time of the adsorption process and the regeneration process and ensuring a larger amount of humidification per unit time. It becomes shorter than the time (t _cha 0, t _cha ). However, as shown in FIG. 7, for a while after startup, the regeneration outlet air relative humidity (Φ _deo ) is highly likely to increase rapidly, as shown in FIG. 7, the regeneration outlet air relative humidity (Φ _deo). ) Is preferably set long so that it can be stabilized.

  8 to 10 show that, in the dehumidifying / humidifying apparatus shown in FIGS. 1 and 3, after the moisture in the ambient air is sufficiently adsorbed to the entire moisture adsorbing means 1, the first air path switching damper 5 and The results are measured when the heating means 4 is operated in a state where the second air path switching damper 6 is fixed without rotating, that is, in a state where no moisture is newly supplied to the moisture adsorption means 1.

In actual operation, since the first air path switching damper 5 and the second air path switching damper 6 rotate, the dehumidifying / humidifying amount (W) / the set dehumidifying / humidifying amount (W _set ) and the regeneration outlet air relative humidity (Φ _deo ) Is a larger value. Therefore, in addition to the control of the heating means control values shown in FIG. 7 (Q), as a conceptual diagram of a dehumidification amount control method shown in FIG. 11, the suction air air volume by the first blowing means 2 (V _ad) It is better to perform the same control.

In FIG. 11, the description of the same parts as in FIG. 7 is omitted, but the graph 71 shows the time-series change of the amount of adsorbed air flow (V _ad ) by the first blower driving motor 52, and the amount of adsorbed air flow (V _ad ). This means that the amount of moisture adsorbed by the moisture adsorbing means 1 changes, so that the dehumidification / humidification amount (W) and the regeneration outlet air relative humidity (Φ _deo ) change. Further, the graph 72 is a set value (V _{ad_set} ) of the adsorbed air flow rate. By setting the adsorbed air flow rate (V _ad ) as the set value (V _{ad_set} ), the dehumidifying / humidifying device shown in FIGS. It shows that the dehumidifying / humidifying amount (W) of the set value (W _set ) can be obtained. The set value 73 is a suction air initial air volume to mean suction air air volume damper switching _(V ad_ini), only at start as startup suction air initial air volume 73a _(V ad_ini 0), slightly lower than V _{Ad_ini} It is set.

As shown in the time-series change 71 in FIG. 11, V _ad = V _{ad_ini} <V _{ad_set} is set when the damper is _switched , and the amount of adsorbed air flow (V _ad ) is set during the control value change time (t _cha ). By setting V _ad = V _{ad_set} after elapse of t _cha from the damper switching, the dehumidification / humidification amount (W) gradually increases and t _cha from the damper switching as indicated by the time series change 61. After elapse, W = W _set is reached. In addition, the regeneration outlet air relative humidity (Φ _deo ) gradually increases but does not reach 100% RH as shown by the time series change 62, and decreases after t _cha elapses. It becomes possible to operate the regeneration outlet air B2 more reliably without causing condensation.

In particular, at the time of start-up when the operation is resumed after being left for a certain period of time, there is a high possibility that the regeneration outlet air relative humidity (Φ _deo ) will rise more than when the normal damper is _switched. set low _V ad_ini 0 than V _{Ad_ini,} similarly controlled value changing time is set longer t _cha 0 from t _cha. Here, as a general method for controlling the amount of adsorbed air flow (V _ad ), the number of rotations of the drive motor 52 of the first blower 2 and the voltage or frequency supplied to the drive motor 52 may be changed.

Although the time series change 60 of the heating means control value (Q) in FIG. 7 is set in a stepwise manner, it may be set so as to be changed continuously. A function that monotonously increases the heating means control value (Q) with respect to time is set in the memory 51 in advance, and the control unit 50 reads it and sets the dehumidification / humidification amount (W _set ) from the set value at the start of operation. The heating means control value (Q) may be controlled so as to continuously increase with time.

  In FIG. 1, the first air blowing unit 2 and the second air blowing unit 3 are installed on the leeward side of the moisture adsorption unit 1 to suck out the adsorption outlet air A2 and the regeneration outlet air B2, respectively. May be configured to push in the adsorption inlet air A1 and the regeneration inlet air B1, respectively, or to suck out one of them and push in the other.

  Further, in FIGS. 1 and 3, the second air inlet is provided in the first layer 10 so that the flow direction of the air passing through the moisture adsorbing means 1 is opposed by the first air blowing means 2 and the second air blowing means 3. 13 and the first exhaust port 12, and the fourth layer 40 is provided with the first intake port 42 and the second exhaust port 43. You may reverse the up-and-down position. Moreover, the position of the 1st exhaust port 12 installed in the 1st layer 10 and the 1st inlet port 42 installed in the 4th layer 40 is reversed, and the adsorption | suction process and regeneration process in the moisture adsorption means 1 are parallel. It may be performed in a stream.

  As described above, the input value of the heating means is set smaller than the target set value for ensuring the target performance, and the operation in the regeneration process is started, and then the target is set stepwise or continuously during the predetermined period. By approaching the value, the humidity of the humidified air is suppressed to 100% or less, so that a dehumidifying / humidifying device capable of continuing the dehumidifying / humidifying operation without causing condensation in the air path on the humidified air side is obtained. it can.

FIG. 12 is a flowchart showing the control method of the first embodiment, and the control method of the humidifier will be described based on this flowchart.
7 and Table 1, when the damper is switched once, the control shifts from the start time (time t ≦ t _dump ) to the normal time (t> t _dump ). When the region 1b of the moisture adsorbing means 1 that has been performing the adsorption process at the position <A> shifts to the damper position <B> by the damper switching and shifts to the regeneration process, the dehumidification / humidification amount (W) and the regeneration outlet air relative Since the humidity (Φ _deo ) is highly likely to rise rapidly as shown in FIGS. 8 to 10, here, the control at the start-up is repeated twice.

When the power is turned on in step S1-1, the control unit 50 drives the first blower drive motor 52, the second blower drive motor 53, and the power supply means 54 of the heating means in step S1-2. Next, when it is confirmed in step S1-3 that the time t after the power is turned on in step S1-1 is equal to or less than t _dump , the control unit 50 is preinstalled in the memory 51 in steps S1-4 to S7. The time t ₀₁ and t after the power is turned on in S1-1 after reading the time t and the setting value of the heating means control value (Q) that differ depending on the installation environment and use place as shown in Table 1. _The power supply means 54 is controlled based on the value of the heating means control value (Q) read out with respect to the values of ₀₂ , t ₀₃ (= t _cha 0), t ₀₄ (= t _dump ).

When 0 <t ≦ t ₀₁ , the heating means control value (Q) is set to Q _01. Similarly, when t ₀₁ <t ≦ t ₀₂ , Q ₀₂ is set, when t ₀₂ <t ≦ t ₀₃ is set to Q ₀₃ , and t ₀₃ When <t ≦ t ₀₄ , Q ₀₄ (= Q _set ) is set. This control is fed back until t> t _dump . When it is confirmed in step S1-3 that the time t has passed t _dump , the time t is reset in step S1-8, and in step S1-9. The controller 50 drives the air path switching damper rotation motor 55 to switch the damper.

In step S1-10, it is determined whether or not the damper switching is the first time. If it is determined that the damper switching is the first time, the process returns to S1-3 and repeats the startup control of S1-3 to S9. When it is determined that it is after, the process proceeds to the normal control after step S1-11. In S1-11, since the time t is reset in S1-8, the control unit 50 is preliminarily assembled in the memory 51 in steps S1-12 to S14 based on the elapsed time t ′ from the damper switching. The time t and the set value of the heating means control value (Q) that differ depending on the installation environment and use place as shown in Table 1 are read, and the elapsed times t ₁ and t ₂ (= t _cha ) since the damper switching. , T ₃ (= t _dump ), the power supply means 54 is controlled based on the value of the heating means control value (Q) read out.

When 0 <t ′ ≦ t ₁ , the heating means control value (Q) is set to Q _1. Similarly, when t ₁ <t ′ ≦ t ₂ , Q _2, and when t ₂ <t ′ ≦ t ₃ , Q ₃ ( = Q _set ). This control is fed back until t ′> t _dump , and when it is confirmed in S1-11 that the elapsed time t ′ from the damper switching has passed t _dump , the elapsed time t ′ in step S1-15. Is reset, and in step S1-16, the control unit 50 drives the air path switching damper rotation motor 55 to switch the damper. Thereafter, the process returns to S1-11 and the normal control of S1-11 to S16 is repeated.

The first adsorption air air volume by the air supply means 2 for (V _ad) also, the flow chart of steps S1-4 through 7 of FIG. 12, and step S1-12 to 14 heating means control values shown in FIG. 11 (Q) By using the same control method as when the air flow rate is changed to the adsorbed air flow rate (V _ad ), the regeneration outlet air relative humidity (Φ _deo ) gradually increases as shown by the time series change 62. Since it changes without reaching% RH and decreases after t _cha elapses, the regeneration outlet air B2 can be operated without causing condensation more reliably.

Embodiment 2. FIG.
The second embodiment of the present invention has the same configuration as that of the first embodiment, and a description of the outline of the configuration is omitted.
FIG. 13 is a conceptual diagram of a dehumidifying / humidifying amount control method according to the second embodiment.
A graph 74 shows a time-series change in the regenerative air flow rate (V _de ) by the second air blowing means drive motor 53. This means that the dehumidification / humidification amount (W) and the regeneration outlet air relative humidity (Φ _deo ) change due to the change in the regeneration air flow rate (V _de ). The set value 75 is a set value (V _{de_set} ) of the regenerative air flow rate. By setting the regenerative air flow rate (V _de ) as the set value (V _{de_set} ), the dehumidifying / humidifying device shown in FIGS. The dehumidifying / humidifying amount (W) of the set value (W _set ) is obtained. The set value 76 is regeneration air initial air volume to mean regeneration air air volume damper switching _(V de_ini), only at start as startup suction air initial air volume 76a _(V de_ini 0), slightly higher setting than V _{De_ini} Has been. Since others are the same as those of the first embodiment, description thereof is omitted.

As for the regeneration air volume (V _de ), the time series of the dehumidification / humidification amount (W) and the regeneration outlet air relative humidity (Φ _deo ) when the heating means control value (Q) shown in FIGS. A trend similar to change is assumed. That is, in the configuration shown in FIGS. 1 and 3, the temperature of the regeneration inlet air B1 after passing through the heating means 4 decreases as the regeneration air volume (V _de ) increases (heating means control value (Q)). In the state where the moisture in the ambient air is sufficiently adsorbed by the moisture adsorption means 1, the maximum value of the dehumidification / humidification amount (W) and the regeneration outlet air relative humidity (Φ _deo ) is reduced, The time drop begins late. However, the decrease in the dehumidification / humidification amount (W) is simply supplemented by the large amount of the regenerative air flow (V _de ) even if the temperature of the regeneration inlet air B1 is low and the amount of moisture released is small. It is assumed that the value (Q) does not increase as much as the value (Q) decreases. On the other hand, if the same regeneration air air volume (V _de), the higher the ambient air relative humidity, since the initial adsorbed water content and total amount of discharged water is large, dehumidification amount (W) and playback outlet air relative humidity ([Phi _deo It is assumed that the maximum value of) is large and that the decline in time will be delayed.

An example of the operation of the dehumidifying / humidifying amount control method shown in FIG. 13 will be described based on the assumed tendency.
In the dehumidifying / humidifying device as shown in FIGS. 1 and 3, the first air path switching damper 5 and the second air path switching damper 6 are rotated, and the adsorption process is shifted to the regeneration process as described in FIG. At this time, the dehumidifying / humidifying amount (W) and the regeneration outlet air relative humidity (Φ _deo ) are highly likely to rise rapidly as shown in FIGS.

In particular, at the time of start-up when the operation is resumed after being left for a certain period of time, the moisture adsorbing means 1 adsorbs moisture in the surrounding air even if the first blowing means 2 and the second blowing means 3 are stopped. For example, when a dehumidifying / humidifying device is installed in a high-humidity outdoor space such as a standard heating condition (7 ° _{C./87% RH} ), V _de / V _{de_set} = 2.5 as the regeneration air flow rate (V _de ). As shown in the graph 70d of FIG. 10, the temperature of the regeneration inlet air B1 corresponds to the case where the heating means control value (Q) is limited to Q / Q _set = 0.4. The outlet air relative humidity (Φ _deo ) reaches 100% RH, and the regeneration outlet air B2 is condensed.

Therefore, as shown in the time series change 74 of the regenerative air flow rate (V _de ) in FIG. 13, V _de = V _{de_ini} > V _{de_set} is set at the time of damper switching, and during the control value change time (t _cha ). Then, the regenerative air flow rate (V _de ) is lowered stepwise, and V _de = V _{de_set} is set after t _cha elapses from the damper switching. Then, the dehumidification / humidification amount (W) gradually increases and reaches W = W _set after t _cha elapse from the damper switching, as shown in the time series change 61, and the regeneration outlet air relative humidity (Φ _deo ) As shown in the series change 62, it gradually rises but does not reach 100% RH, and decreases after t _cha elapses. Therefore, it is possible to operate without condensing the regeneration outlet air B2. It becomes.

In particular, at the time of start-up when the operation is restarted after being left for a certain period of time, the regeneration outlet air relative humidity (Φ _deo ) is more likely to rise than when the normal damper is _switched. , set to a higher _V de_ini 0 than V _{De_ini,} similarly controlled value changing time is set longer t _cha 0 from t _cha. Here, as a general method for controlling the regenerative air flow rate (V _de ), the rotational speed of the drive motor 53 of the second blower 3 and the voltage or frequency supplied to the drive motor 53 may be changed.

Here, the time series change 74 in the regeneration air air volume (V _de), for example, as shown in Table 2, depending on the relative humidity of the ambient air, low humidity (Figure 8: 60% RH) assuming a standard (Fig. 9: 80% RH) assumption and high humidity (FIG. 10: 90% RH) assumption, the relationship between the time (t) and the regeneration air volume (V _de ) is set and incorporated in the memory 51. In this case, regeneration air air volume damper switching only at startup as during regeneration air initial air volume start _{(V de01 = V de_ini 0)} , is set higher than the regeneration air the initial air volume of normal _{(V de1} = V de_ini) . Similarly, the period during which the regeneration air flow rate (V _de ) is changed is the control value change time at start (t ₀₁ + t ₀₂ + t ₀₃ = t _cha 0) only at the start, and the normal control value change period (t _1). + T ₂ = t _cha ). Further, as the relative humidity of the assumed ambient air is higher, the heating means control values (V _de01 , V _de02 , V _de03 , V _de1 , V _de2 ) are set higher and the control value change time (t ₀₁ , t _02). , T ₀₃ , t ₁ , t ₂ ) are set long.

The setting method shown in Table 2 is an example, and a setting corresponding to the installation environment, region, or the like may be used. Moreover, in order to completely avoid the condensation of the regeneration outlet air B2, a setting assuming high humidity (90% RH) may always be used. In Table 2, for each humidity assumption, the time t _dump from the start to the first damper switching is divided into four, and thereafter, the regeneration air volume (V _de ) is set in three. The number of divisions may be changed depending on the assumption.

起動から時刻ｔ＝０〜ｔ_cha０までは、時間ｔ₀₁、ｔ₀₂、ｔ₀₃に対応して、再生空気風量（Ｖ_de）をＶ_de01、Ｖ_de02、Ｖ_de03に設定し、その後時刻ｔ＝ｔ_cha０〜ｔ_dumpの時間ｔ₀₄の間は、Ｖ_de04＝設定値Ｖ_{de_set}に設定する。起動後１回目のダンパ切換終了ｔ＝ｔ_dump以降は、ダンパ切換からｔ_chaの間は、時間ｔ₁、ｔ₂に対応して、再生空気風量（Ｖ_de）をＶ_de1、Ｖ_de2に、ｔ_cha経過後から次のダンパ切換までの時間ｔ₃の間は、Ｖ_de3＝設定値Ｖ_{de_set}に設定することを繰り返す。

From the time t = 0 to t _cha 0, the regeneration air volume (V _de ) is set to V _de01 , V _de02 , V _de03 corresponding to the times t ₀₁ , t ₀₂ , t ₀₃ , and then the time t = T _cha 0 to t _dump time t ₀₄ is set to V _de04 = set value V _{de_set} . From the end of the first damper switching after startup t = t _dump , the regeneration air volume (V _de ) is set to V _de1 and V _de2 corresponding to the times t ₁ and t ₂ from the damper switching to t _cha . During the time t ₃ after the time t _cha elapses until the next damper switching, the setting of V _de3 = set value V _{de_set} is repeated.

8 to 10 and the set value of the time series change 74 of the regeneration air flow rate (V _de ) in Table 2 are based on the regeneration outlet air B2 immediately after being released from the dehumidifying / humidifying device. However, for example, when a dehumidifying / humidifying device is installed outdoors and the regeneration outlet air B2 is conveyed by a duct to humidify the room, the regeneration outlet air B2 may be cooled and condensed in the duct conveyance process. _Therefore , the control value change time (t _cha 0, t _cha ) is longer than the values shown in Table 2, and the regeneration air volume (V _de01 , V _de02 , V _de03 , V _de1 , V _de2 ) is set higher. There is a need to.

8 to 10 show that after the moisture in the ambient air is sufficiently adsorbed by the entire moisture adsorbing means 1 in the dehumidifying / humidifying device shown in FIGS. 1 and 3, the first air path switching damper 5 and This is a result measured when the heating unit 4 is operated in a state where the second air path switching damper 6 is fixed without rotating, that is, in a state where no moisture is newly supplied to the moisture adsorbing unit 1. However, since the first air path switching damper 5 and the second air path switching damper 6 rotate in actual operation, the dehumidification / humidification amount (W) / set dehumidification / humidification amount (W _set ) and the regeneration outlet air relative humidity (Φ) _deo ) is a larger value.

Therefore, in the same manner as in the first embodiment, in addition to the control of the regeneration air flow rate (V _de ) shown in FIG. 13, the adsorption by the first air blowing means 2 as shown in the conceptual diagram of the dehumidification / humidification amount control method shown in FIG. The air flow rate (V _ad ) is also set to V _ad = V _{ad_ini} <V _{ad_set} when the damper is _switched , as indicated by the time series change 71, and the adsorbed air during the control value change time (t _cha ). The air volume (V _ad ) is increased stepwise, and V _ad = V _{ad_set} is set after t _cha elapses from the damper switching. Then, the dehumidification / humidification amount (W) gradually increases and reaches W = W _set after t _cha elapses from the damper switching, as shown in the time series change 61, and the regeneration outlet air relative humidity (Φ _deo ) is As shown in the time series change 62, it gradually rises but does not reach 100% RH and decreases after t _cha elapses, so that the regeneration outlet air B2 is operated without condensation more reliably. It becomes possible to do.

In particular, at the time of start-up when the operation is resumed after being left for a certain period of time, there is a high possibility that the regeneration outlet air relative humidity (Φ _deo ) will rise more than when the normal damper is _switched. set low _V ad_ini 0 than V _{Ad_ini,} similarly controlled value changing time is set longer t _cha 0 from t _cha. Here, as a general method for controlling the amount of adsorbed air flow (V _ad ), the number of rotations of the drive motor 52 of the first blower 2 and the voltage or frequency supplied to the drive motor 52 may be changed. .

In the time series change 74 of the regeneration air flow rate (V _de ) in FIG. A function that monotonously decreases the regenerative air flow rate (V _de ) with respect to time is set in the memory 51 in advance, and the control unit 50 reads it and sets the dehumidification / humidification amount (W _set ) from the set value at the start of operation. The regeneration air volume (V _de ) may be controlled so as to decrease continuously over time.

  As described above, the regeneration air flow rate is set larger than the target set value for ensuring the target performance, and the operation in the regeneration process is started, and thereafter, the target set value is set stepwise or continuously during a predetermined period. By approaching, the humidity of the humidified air is suppressed to 100% or less, so that a dehumidifying / humidifying device capable of continuing the dehumidifying / humidifying operation without causing condensation in the air path on the humidified air side can be obtained.

FIG. 14 is a flowchart showing the control method of the second embodiment, and the control method of the humidifier will be described based on this.
In FIG. 13 and Table 2, when the damper is switched once, the control shifts from the start time (time t ≦ t _dump ) to the normal time (t> t _dump ). However, when the region 1b of the moisture adsorbing means 1 that has been performing the adsorption process at the damper position <A> in FIG. 6 at the time of startup is shifted to the damper position <B> by the damper switching and then transferred to the regeneration process, the dehumidification amount Since (W) and the regeneration outlet air relative humidity (Φ _deo ) are highly likely to increase rapidly as shown in FIGS.

Also in the second embodiment, the flow chart of steps S1-4 through 7 of FIG. 12, and by changing the step S1-12 to 14 heating means control value of (Q) to the regeneration air air volume V _de, steps S2-4 through 7 and steps S2-12 to 14 are used. However, as shown in Table 2, the value of the regeneration air volume V _de preset in the memory 51 decreases as the time t increases, and the heating means control value (Q) is set stepwise or continuously. Similarly to the case where the temperature is increased, the temperature of the regeneration inlet air B1 after passing through the heating means 4 gradually increases. Therefore, since the humidity of the regeneration outlet air B2 is suppressed to 100% or less, the humidification operation can be continued without causing condensation in the air path on the humidified air side.

Embodiment 3 FIG.
FIG. 15 is a schematic configuration diagram of a dehumidifying / humidifying device according to Embodiment 3 of the present invention, in which an intake air sensor 56 that detects the temperature or humidity of the intake air A0 is installed in addition to the configuration of Embodiment 1. It is. FIG. 16 is an internal perspective view of the dehumidifying / humidifying device in Embodiment 3 of the present invention.
In FIG. 15, the setting previously incorporated in the memory 51 is read based on the detection value of the intake air sensor 56 and input to the drive motor 52 of the first blower means 2, the drive motor 53 of the second blower means 3, or the heating means 4. A function for controlling at least one of the power supply means 54 for determining the power supply amount (control value) to be performed is added to the control unit 50.

FIG. 17 is a conceptual diagram of a dehumidifying / humidifying amount control method according to Embodiment 3 of the present invention.
A graph 77 shows a time-series change of the intake air temperature (To) detected by the intake air sensor 56, a set value 78 is an intake air temperature threshold (To _tri ), a set value 78a is a high temperature side threshold (To _{tri_h} ), and a set value. 78b is a low temperature side threshold value ( _{Totri_l} ).
The suction air temperature (the To), the suction air temperature hot side threshold _78a (To tri_h), and the suction air temperature low side threshold _78b (To tri_l) and the heating means control value by a relationship among the (Q) is changed, dehumidification It means that the quantity (W) and the regeneration outlet air relative humidity (Φ _deo ) change. The other parts are the same as those in the first embodiment, and thus the description thereof is omitted.

Next, an example of the operation will be described. The basic operation in the configuration of FIG. 16 and the basic control method of the dehumidifying / humidifying amount shown in FIG.
In FIG. 17, as shown in the time series change 60 of the heating means control value (Q), the first air path switching damper 5 and the second air path switching damper 6 are rotated to shift from the adsorption process to the regeneration process. Q = Q _ini <Q _set is set, the heating means control value (Q) is increased stepwise during the control value change time (t _cha ), and after t _cha elapses from the damper switching, Q = _Set to Q _set . Then, the dehumidifying / humidifying amount (W) gradually increases and reaches W = W _set after t _cha elapses from the damper switching, as indicated by the time series change 61. The regeneration outlet air relative humidity (Φ _deo ) gradually increases but does not reach 100% RH as indicated by the time series change 62, and decreases after the passage of t _cha. It becomes possible to drive without dewing B2.

  Here, as the time-series change 60 of the heating means control value (Q), as shown in Table 1, for example, as shown in Table 1, the humidity is reduced according to the relative humidity of the ambient air (FIG. 8: 60). % RH) assumption, standard (Fig. 9: 80% RH) assumption, and high humidity (Fig.10: 90% RH) assumption, the relationship between time (t) and heating means control value (Q) is set Alternatively, a setting corresponding to the installation environment, region, etc. may be used.

That is, a prediction model for controlling the humidification amount corresponding to the detection value of the intake air sensor 56 as shown in Table 1 is incorporated in the memory 51 in advance. Moreover, in order to completely avoid the condensation of the regeneration outlet air B2, a setting assuming high humidity (90% RH) may always be used. Desirably, the relative humidity of the ambient air is directly detected by the intake air sensor 56, or the time series change 77 of the intake air temperature (To) is detected as shown in FIG. <To _{tri_l} is set for low humidity (60% RH), To _{tri_l} ≤ To <To _{tri_l} is set for standard (80% RH), and To> To _{tri_h} is set for high humidity (90% RH). It is good to choose.

8 to 10 and the set value of the time series change 60 of the heating means control value (Q) in Table 1 are based on the regeneration outlet air B2 immediately after being released from the dehumidifying / humidifying device. However, for example, when a dehumidifying / humidifying device is installed outdoors and the regeneration outlet air B2 is conveyed by a duct to humidify the room, the regeneration outlet air B2 may be cooled and condensed in the duct conveyance process. Therefore, the control value change time (t _cha 0, t _cha ) is longer and the heating means control values (Q ₀₁ , Q ₀₂ , Q ₀₃ , Q ₁ , Q ₂ ) are lower than the values shown in Table 1. Must be set.

The dehumidifying / humidifying amount control method shown in FIG. 17 is for the case where the air path switching damper switching time (t _dump )> the control value change time (t _cha 0, t _cha ), and before the damper switching is performed. The heating means control value (Q) is always controlled to reach the _set value (Q _set ), but when t _dump ≦ t _cha 0 or t _dump ≦ t _cha , Q reaches Q _set. Even if not, it is necessary to set Q to the heating means initial control value (Q _ini ).

However, this air path switching damper switching time (t _dump ) is for optimizing the operation time of the adsorption process and the regeneration process and ensuring a larger amount of humidification per unit time. It becomes shorter than the time (t _cha 0, t _cha ). However, regeneration outlet air relative humidity ([Phi _deo) rapidly during the high starting after a while may increase, as shown in FIG. 17, dehumidification amount (W) and playback outlet air relative humidity ([Phi _deo ) Is preferably set long so that it can be stabilized.

FIG. 17 shows an example of the control method based on the heating means control value (Q) as in the first embodiment. However, as in the second embodiment, the regeneration air flow rate (V _de ) is changed to the control value change time. You may reduce in steps during (t _cha 0, t _cha ). Further, in addition to the control by the heating means control value (Q) and the regenerative air flow rate (V _de ), as shown in the first and second embodiments, the adsorption air flow rate (V _ad ) is also controlled by the control value change time (t _It may be raised stepwise during _cha 0, t _cha ) to reliably prevent condensation in the regeneration outlet air B2.

In the time series change 60 of the heating means control value (Q) in FIG. 17, the heating means control value (Q) is set to change stepwise, but may be changed to change continuously. . A function that monotonously increases the heating means control value (Q) with respect to time is set in the memory 51 in advance, and the control unit 50 reads it and sets the dehumidification / humidification amount (W _set ) from the set value at the start of operation. The heating means control value (Q) may be controlled so as to continuously increase with time.

  As described above, in order to ensure the target performance by controlling the input value of the heating means, the regeneration air volume, and the adsorption air volume in the predetermined period after the start of the regeneration process where the relative humidity of the humidified air is likely to be high. The dehumidifying / humidifying operation is performed without causing condensation in the air path on the humidified air side by setting the value so that the dehumidifying / humidifying amount is smaller than the target setting value of the Can be obtained. At this time, the temperature or humidity of the intake air is detected, and the setting period is shortened by setting the period during which the input value of the heating means, the regeneration air volume and the adsorption air volume are changed from the target set value based on the detected value. Generation | occurrence | production of the dew condensation in the humidified air side air path by being too much, and the dehumidification amount deficiency by setting time being too long can be prevented.

<About control>
18 to 19 are flowcharts showing the control method of the third embodiment, and the control method of the humidifier will be described based on this.
17 and Table 1, when the damper is switched once, the control shifts from the start time (time t ≦ t _dump ) to the normal time (t> t _dump ). When the region 1b of the moisture adsorbing means 1 that has been performing the adsorption process at the position <A> shifts to the damper position <B> by the damper switching and shifts to the regeneration process, the dehumidification / humidification amount (W) and the regeneration outlet air relative Since the humidity (Φ _deo ) is highly likely to rise rapidly as shown in FIGS. 8 to 10, here, the control at the start-up is repeated twice.

When the power is turned on in step S1-1, the control unit 50 drives the first blower drive motor 52, the second blower drive motor 53, and the power supply means 54 of the heating means in step S1-2. In step S3-3, the control unit 50 reads the intake air temperature To by the intake air sensor 56. Assuming absolute humidity from the read temperature To and determining that the humidity is low, standard or high in step S3-4, the control unit 50 is incorporated in the memory 51 in advance in steps S3-5 to S7. Tables of t ₀₁ , t ₀₂ , t ₀₃ (= t _cha 0), t ₀₄ (= t _dump ), Q ₀₁ , Q ₀₂ , Q ₀₃ , Q ₀₄ (= Q _set ) at each humidity assumption reads the relationship table, such as 1, is set to _{t 01, t 02, t 03} , the heating means control value corresponding to t ₀₄ the (Q), respectively _{Q 01, Q 02, Q 03} , Q 04.

Next, in step S3-8, when it is confirmed in step S1-1 that the time t from when the power is turned on is equal to or less than t _dump , the set values in steps S3-5 to S7 are set in steps S3-9 to S12. As in steps S1-4 to S7 of the first embodiment, the heating means control value (Q) is set according to the time t after the power is turned on to control the power supply means 54. This control is fed back until t> t _dump . When it is confirmed in step S3-8 that the time t has passed t _dump , the time t is reset in step S3-13, and in step S3-14. The controller 50 drives the air path switching damper rotation motor 55 to switch the damper. In step S3-15, it is determined whether or not the damper switching is the first time. If it is determined that the damper switching is the first time, the process returns to S3-3 and repeats the startup control of S3-3 to 14, for the second time. When it determines with it being after, it progresses to the normal time control after step S3-17 shown in FIG. 19 via step S3-16.

In step S3-17, the control unit 50 reads the intake air temperature To by the intake air sensor 56, assumes absolute humidity from the read temperature To, and determines in step S3-18 that the humidity is low, standard or high. In steps S3-19 to S21, the control unit 50 is incorporated in the memory 51 in advance, and t ₁ , t ₂ (= t _cha ), t ₃ (= t _dump ), Q ₁ in each humidity assumption. A relational table such as Table 1 of Q ₂ , Q ₃ (= Q _set ) is read, and heating means control values (Q) corresponding to t ₁ , t ₂ , t ₃ are respectively set to Q ₁ , Q ₂ , Q _3. Set to.

Next, in step S3-22, since the time t is reset in S3-13, based on the elapsed time t ′ from the damper switching, in steps S3-23 to 25, in steps S3-19 to 21. In the same manner as steps S1-12 to S14 of the first embodiment, the elapsed time t ₁ , t ₂ (= t _cha ), t ₃ (= t _dump ) from the damper switching is used. The power supply means 54 is controlled based on the value of the heating means control value (Q) read out. This control is fed back until t ′> t _dump , and when it is confirmed in step S3-22 that the elapsed time t ′ from the damper switching has passed t _dump , the elapsed time t ′ in step S3−26. Is reset, and in step S3-27, the control unit 50 drives the air path switching damper rotation motor 55 to switch the damper. Thereafter, the process returns to S3-17, and the normal time control of S3-17 to S27 is repeated.

  FIGS. 17 to 19 illustrate a control method in which the temperature of the intake air is detected by the intake air sensor 56 and the humidity is assumed from the temperature. However, the humidity of the intake air is directly detected and incorporated in the memory 51 in advance. Of course, the same control may be performed using the setting at the time of low temperature, standard temperature or high temperature.

In the above description, the humidifying device that controls the heating means control value (Q) of the heating means 4 based on the detection value of the suction air sensor 56 has been described. (V _ad ) or when the regeneration air volume (V _de ) by the second air blowing means 3 in FIG. 13 described in the second embodiment is controlled based on the detection value of the intake air sensor 56, the regeneration outlet air relative The humidity (Φ _deo ) gradually increases but does not reach 100% RH as indicated by the time-series change 62, and decreases after the passage of t _cha, so that the regeneration outlet air B 2 is condensed. It becomes possible to drive without.

In this air volume control, the heating means control value (Q) in steps 3-5 to 7 or S3-9 to 12 in FIG. 18 and steps 3-19 to 21 or S3-23 to 25 in FIG. It can be implemented by changing to (V _ad ) or the regeneration air flow rate (V _de ) and using the same control method. In addition to controlling one of the heating means control value (Q), the adsorbed air flow rate (V _ad ), or the regeneration air flow rate (V _de ), it is possible to adjust the humidification amount by combining two or more of these. In this case, the operation can be performed without more reliably condensing the regeneration outlet air B2.

Embodiment 4 FIG.
FIG. 20 is a schematic configuration diagram of a dehumidifying / humidifying device in Embodiment 4 of the present invention.
In addition to the configuration of the first embodiment, the suction inlet air sensor 56a that detects the temperature or humidity of the suction inlet air A1 (= suction air A0), and the suction outlet air sensor 57a that detects the temperature or humidity of the suction outlet air A2. Further, a deterioration detecting means 58 for detecting deterioration of the moisture adsorbing means 1 from a change with time of detection values of the adsorption inlet air sensor 56a and the adsorption outlet air sensor 57a and a display section 59 for displaying when the deterioration is detected are provided. Furthermore, the set value previously incorporated in the memory 51 is changed according to the detection value of the deterioration detection means 58, and the drive motor 52 of the first blower means 2, the drive motor 53 of the second blower means 3, or the heating means 4 is changed. A function for controlling at least one of the power supply means 54 that determines the input power supply amount (control value) is added to the control unit 50.

FIG. 21 is a detailed view of the air path configuration around the moisture adsorbing means 1 according to the fourth embodiment of the present invention, and is arranged inside the dehumidifying / humidifying device shown in FIG. 3 in the first embodiment. .
In FIG. 21, each component is disassembled and shown in an easy-to-understand manner as in FIG. 4, but in reality the components adjacent in the vertical direction are in close contact. Although the description of the same parts as those in the first embodiment is omitted, in addition to the suction inlet air sensor 56a and the suction outlet air sensor 57a shown in FIG. 20, the regeneration inlet air for detecting the temperature or humidity of the regeneration inlet air B1. A regeneration outlet air sensor 57b for detecting the temperature or humidity of the sensor 56b and the regeneration outlet air B2 is provided.

Regarding operation, basically, as in the first embodiment, the first air path switching damper 5 and the second air path switching damper 6 are rotated to switch the air path, thereby continuously supplying humidified air into the room. Details are omitted.
At this time, the air passing through the first air inlet 42, the first air outlet 12, the second air inlet 13, and the second air outlet 43 in either of the damper positions <A> or <B> shown in FIG. Are always the adsorption inlet air A1, the adsorption outlet air A2, the regeneration inlet air B1 and the regeneration outlet air B2. Therefore, the air sensors 56a, 57a, 56b and 57b always detect the temperature or humidity of the target air.

  Therefore, in the adsorption area (area 1b at the damper position <A> and area 1a at the damper position <B>), the adsorbent carried by the moisture adsorption means 1 adsorbs moisture in the adsorption inlet air A1 and generates heat. Since the reaction occurs, the temperature rises and the humidity falls in the adsorption outlet air sensor 57a with respect to the value detected in the adsorption inlet air sensor 56a. On the other hand, in the regeneration region (region 1a when the damper position <A>, region 1b when the damper position <B>), moisture is regenerated from the adsorbent carried on the moisture adsorbing means 1 by the high-temperature regeneration inlet air B1. Since the endothermic reaction occurs, the temperature at the regeneration outlet air sensor 57b decreases and the humidity increases with respect to the value detected by the regeneration inlet air sensor 56b.

For example, the adsorption energy of the adsorbent 5b carried on the moisture adsorbing means 1 is 800 kcal per 1 kg of adsorbed moisture as a general zeolite value, and the air volume by the first blowing means 2 and the second blowing means 3 is 3 m. Assuming that the humidification amount is 1 L / h at ³ / min, the temperature is about 15 ° C. and the absolute humidity is about 4.6 g if heat loss is ignored before and after the moisture adsorbing means 1. / Kg will change.

  Here, the adsorbent carried on the moisture adsorbing means 1 adsorbs not only moisture in the air but also other gas components. For example, when the adsorption inlet air A1 is supplied from outside, NOx or the like generated from the exhaust gas of an automobile or the like, when supplied from the room, ammonia or VOC generated from tobacco smoke is the type of adsorbent. Some are adsorbed once in the adsorption process. The high-temperature regeneration inlet air B1 is discharged together with moisture in the regeneration process, but it accumulates in the moisture adsorbing means 1 over time, and the adsorbent structure may be destroyed to reduce the humidification amount.

  When the humidification amount decreases, the difference in temperature and humidity before and after the moisture adsorption means 1 described above also becomes small. When the temperature and humidity of the inlet air are constant, if the humidification amount is halved, the temperature difference and absolute humidity difference are also halved. To do. Therefore, whether the design values of the temperature and humidity to be detected by the adsorption outlet air sensor 57a and the regeneration outlet air sensor 57b are determined with respect to the temperature and humidity detected by the adsorption inlet air sensor 56a and the regeneration inlet air sensor 56b. Alternatively, the deterioration of the adsorbent can be confirmed by measuring the initial value and detecting the secular change. At this time, if the adsorbent deteriorates and the amount of humidification decreases, the effect appears on the temperature and humidity. Therefore, either one or both may be detected to improve accuracy.

  In FIG. 21, the adsorption inlet air sensor 56 a before the first intake port 42, the adsorption outlet air sensor 57 a after the first exhaust port 12, the regeneration inlet air sensor 56 b and the second exhaust port 43 before the second intake port 13. However, the regeneration outlet air sensor 57b may be installed only on either the adsorption process side or the regeneration process side.

  Since the dehumidification amount in the adsorption process and the humidification amount in the regeneration process are the same, it is possible to detect the deterioration of the adsorbent from the difference in temperature or humidity of either one, and the number of sensors can be reduced. Increase can be suppressed. However, on the regeneration step side, since the high-temperature regeneration inlet air B1 heated by the heating means 4 is detected, an error due to heat loss may be included greatly. As shown, it is desirable to install an adsorption inlet air sensor 56a and an adsorption outlet air sensor 57a.

In addition, as shown in the third embodiment, the heating means control value (Q), the regeneration air flow rate (V _de ), and the regenerative air flow rate (V _de ) When controlling the amount of adsorbed air (V _ad ), among the air sensors 56a, 57a, 56b and 57b, the detection value by the regeneration outlet air sensor 57b is fed back, and each control value and control value change time (t _cha 0, By setting t _cha ), the dehumidifying / humidifying operation is continued without causing the dew condensation in the humidified air side air passage due to the setting period being too short or the dehumidifying amount being insufficient due to the setting period being too long. It is possible to obtain a dehumidifying / humidifying device that can be used.

  As described above, sensors for detecting temperature or humidity are installed before and after the moisture adsorption means, and the change in the temperature or humidity of the outlet air with respect to the temperature or humidity of the inlet air is detected. In addition to the effects shown in Embodiment 1, it is possible to confirm a decrease in the dehumidification / humidification amount with respect to the design value or the initial value, and to detect the secular deterioration of the adsorbent due to adsorption of gas other than moisture. A humidifier can be obtained.

FIG. 22 is a flowchart showing the control method of the fourth embodiment, and the control method of the humidifier will be described based on this.
When the power is turned on in step S1-1, the control unit 50 drives the first blower drive motor 52, the second blower drive motor 53, and the power supply means 54 of the heating means in step S1-2. Control unit at step S4-3 50 is adsorbed inlet air sensor 56a and the suction outlet air sensor 57a detects, reads the suction inlet air temperature T _in and adsorbed outlet air temperature T _out, the control unit 50 in step S4-4 The adsorbed air volume (V _ad ) is read from the rotational speed of the first blower drive motor 52.

In step S4-5, determines that the initial value ΔT0 of the temperature difference of the adsorption outlet air and the suction inlet air, whether the setting of the initial value V _ad 0 of adsorption air air volume have been made. When the initial value is not set, the process proceeds to step S4-6, where the control unit 50 determines the initial operation temperature difference ΔT0 = from T _in and T _out read in S4-2 and V _ad read in S4-3. T _out -T _in is set in the memory 51 as the adsorbed air volume V _ad 0 = V _ad at the initial operation, and the process returns to S4-3. In S4-5, if ΔT0 and V _ad 0 are already set, the process proceeds to step S4-7, and the temperature difference ΔT = T _out −T _in between the suction inlet air and the suction outlet air at that time is calculated.

Next, in step S4-8, the controller 50 divides the product of the adsorbed air flow rate V _ad and the temperature difference ΔT by the product of the initial operation adsorbed air flow rate V _ad 0 and the initial operation temperature difference ΔT0. The degree of deterioration is determined, and it is determined whether or not the degree of deterioration is smaller than a predetermined value c. c is an arbitrary real number less than 1 and is stored in the memory 51 in advance. Of course, a different deterioration degree calculation formula may be used. When the degree of deterioration is smaller than a predetermined value, the process proceeds to step S4-9, and the setting value incorporated in advance in the memory 51 is changed based on the degree of deterioration.

This change, the control value change time _{(t 01, t 02, t} 03 (= t cha 0), t 1, t 2) to apply a respective degree of deterioration, or the heating means control value (Q _01, Q _02, Q ₀₃ , Q ₀₄ (= Q _set ), Q ₁ , Q ₂ , Q ₃ (= Q _set )) and adsorbed air flow (V _ad01 , V _ad02 , V _ad03 , V _ad04 (= V _{ad_set} ), V _ad1 , V _{For ad2} and V _ad3 (= V _{ad_set} ), the values are divided by the degree of deterioration, respectively, and the regeneration air volume (V _de01 , V _de02 , V _de03 , V _de04 (= V _{de_set} ), V _de1 , V _{For de2} and V _de3 (= V _{de_set} )), it may be changed to a value multiplied by the degree of deterioration, but of course, the setting value previously incorporated in the memory 51 is changed using a different relational expression. May be. After the set value is changed, in step S4-9, the display unit 10 displays a content such as “It is time to replace the honeycomb”. If the degree of deterioration obtained in S4-8 is not smaller than a predetermined value, the process returns to S4-3.

  In this way, the adsorbent is detected by detecting the aging deterioration of the adsorbent based on the temperature or humidity detected by the sensors installed before and after the moisture adsorbing means, and by determining the degree of deterioration of the adsorbent and changing the control value. It is possible to obtain a humidifier that can suppress a decrease in humidification performance even if it deteriorates.

When the heat pump cycle performs the heating operation, as described in the first embodiment, the first air path switching damper 5 and the second air path are arranged so that the damper positions <A> and <B> in FIG. 6 are obtained. By repeatedly switching the switching damper 6, the adsorption outlet air A2 that is dry air and the regeneration outlet air B2 that is high-temperature and high-humidity air are continuously discharged from the humidification unit 100. At this time, the regeneration outlet air B2 is conveyed into the room by the second air blowing means 3 via a duct connecting the room and the outside, and is supplied into the room together with the high-temperature air discharged from the indoor unit to heat the room. Humidify.

  In this way, by installing the humidifying unit 100 integrally on the upper part of the outdoor unit 200 of the air conditioner, an air conditioner having a humidifying function without securing a floor space for newly installing the humidifying unit 100 is provided. You can get a chance. Moreover, since it becomes possible to supply humidified air continuously indoors simultaneously with the heating operation of a heat pump cycle, the effect that the drying at the time of heating can be prevented is acquired.

Here, in the predetermined period after the start of the regeneration process where the relative humidity of the humidified air is likely to be high, as shown in the first to third embodiments, the heating means control value (Q), the regeneration air flow rate (V _de ) and adsorbed air volume (V _ad ) are controlled to set the value so that the humidification amount is less than the target set value for ensuring the target performance, and gradually or continuously approach the target set value. Thus, the humidification operation can be continued without causing condensation in the air path on the humidified air side.

In particular, as shown in the third embodiment, the temperature or humidity of the intake air is detected, and the heating means control value (Q), the regeneration air flow rate (V _de ), and the adsorption air flow rate (V _ad ) are determined from the detected values. By setting the period to be changed from the target set value, it is possible to prevent the occurrence of dew condensation in the humidified air side air passage due to the setting period being too short, and the insufficient humidification amount due to the setting period being too long. At this time, in particular, the heating means control value (Q) is _{set to} Q ₀₁ , Q ₀₂ and Q _{03 which} are smaller than the set value Q _set at the time of start-up, and is increased stepwise. The heating means control value (Q) at the time of start-up of a high load where 201 consumes electric power can be suppressed.

  Similarly to the fourth embodiment, the first intake port 42, the first exhaust port 12, the second intake port 13, and the second exhaust port 43 are respectively connected to the adsorption inlet air sensor 56a, the adsorption outlet air sensor 57a, and the regeneration inlet air. A sensor 56b and a regeneration outlet air sensor 57b may be installed. As a result, it is possible to detect a change over time in the temperature or humidity after passage with respect to the passage before the moisture adsorption means 1 and confirm the decrease in the humidification amount with respect to the design value or the initial value, and adsorb gases other than moisture. As a result, it is possible to detect aged deterioration of the adsorbent. At this time, since the air conditioner is often provided with outdoor and indoor temperature sensors, the number of sensors can be reduced and an increase in cost can be suppressed.

  In FIG. 23, the humidifying unit 100 is integrated and installed on the upper part of the outdoor unit 200 of the air conditioner. However, if the humidifying unit 100 is in a position that does not hinder the ventilation of the outdoor unit blower 203, You may install it integrally. In either case, it is possible to guide the regeneration outlet air B2 into the room, and when installed on the bottom surface, the installation floor space does not change, so the same effect as when the humidification unit 100 is integrated and installed at the top is obtained. can get.

  In FIG. 23, as described in the first embodiment, the second air inlet 13 and the first air inlet 13 are formed in the first layer 10 so that the air flow directions in the moisture adsorption means 1 are opposite to each other in the regeneration process. The first intake port 42 and the second exhaust port 43 are installed in the exhaust port 12 and the fourth layer 40, but they are the same counter flow, and the vertical positions of the first layer 10 and the fourth layer 40 are reversed. In addition, the positions of the first exhaust port 12 installed in the first layer 10 and the first intake port 42 installed in the fourth layer 40 are reversed so that the adsorption process and the regeneration process in the moisture adsorption unit 1 are performed. May be performed in parallel flow.

  In this case, in addition to the effects described in the third embodiment, the first exhaust port 12 is disposed in the fourth layer 40 in the vicinity of the air suction port of the outdoor unit heat exchanger 202, and is dry air. Further, the adsorption outlet air A2 whose temperature is slightly higher than the outside air due to the adsorption heat is sucked into the outdoor unit heat exchanger 202 which is an evaporator during the heating operation of the heat pump cycle. The effect of suppressing frost and improving heating operation efficiency can also be expected.

  In FIG. 23, the first blower unit 2 is installed exclusively for exhausting the adsorption outlet air A2, but the humidifying unit 100 is installed integrally with the outdoor unit 200 of the air conditioner. A communication port may be provided, and a part of the air taken in by the outdoor unit blower 203 may be guided to the first intake port 42. In this case, since the outdoor unit blower 203 is also used as the first blower unit 2 and only the second blower unit 3 is required to be installed in the humidifying unit 100, the number of blowers can be reduced and the cost is reduced.

Further, in FIG. 23, the humidifying unit 100 is integrally installed on the upper part of the outdoor unit 200 of the air conditioner. However, if the humidifying unit 100 is operated in conjunction with the air conditioner, the humidifying unit 100 is as shown in FIG. You may install in the outer wall 300a of a building.
When installed on the outer wall 300a of the building, the adsorption air outlet 104 communicating with the first exhaust port 12 is opened to the outside, and the regeneration air outlet 106 communicating with the second exhaust port 43 faces the existing wall hole 301. Although it is necessary to adhere closely, the duct for conveying reproduction | regeneration exit air B2 to a room | chamber becomes unnecessary, and it can achieve cost reduction. Furthermore, since the conveyance distance is the shortest, the air path pressure loss and noise are reduced, the second blower means 3 can be downsized, and an air conditioner having a highly reliable and compact humidifying function can be obtained. .

  Further, when the regeneration outlet air B2 having a high humidity is conveyed by a duct, the duct is cooled by the outside air particularly in winter, so there is a high risk of condensation inside. However, since the duct is unnecessary, the humidifying unit 100 The generated humid air can be effectively supplied indoors without loss. Therefore, the values in Table 1 are used as they are in the control of the heating means control value (Q) in the predetermined period after the start of the regeneration process where the relative humidity of the humidified air is likely to be high as described in the first embodiment. It will be good.

Similarly, if operated in conjunction with the air conditioner, the humidification unit 100 may be installed on the inner wall 300b of the building as shown in FIG.
When installed on the inner wall 300b of the building, the regeneration air outlet 106 communicating with the second exhaust port 43 is opened to the room, and the adsorption air outlet 104 communicating with the first exhaust port 12 faces the existing wall hole 301. It needs to be in close contact. However, as in the case of installing on the outer wall 300a of the building, a duct for transporting the regeneration outlet air B2 into the room is not required, and a compact humidification function can be achieved by downsizing the regeneration air blowing means 3 at a low cost. In addition to obtaining an air conditioner, it is possible to avoid problems such as duct noise and condensation in the duct, and the effect of ensuring reliability can be obtained.

  Further, since the indoor air A0b is used as the adsorption inlet air A1, air below room temperature does not flow inside the humidifying unit 100, and condensation may occur inside the unit as compared with the case where outside air flows through the adsorption air passage. The effect that sex can be avoided is obtained. Furthermore, since the heated indoor air A0b is heated by the heating means 4 and used as the regeneration inlet air B1, the heating means 4 is used to obtain the air temperature necessary for the moisture regeneration in the moisture adsorption means 1. Thus, the energy saving effect that the amount of heat required for temperature increase is reduced can also be obtained. In addition, since the regeneration outlet air B2 is opened to the room as it is, the heating means is used in the predetermined period after the start of the regeneration process, which is likely to increase the relative humidity of the humidified air as described in the first embodiment. In the control of the control value (Q), the values in Table 1 may be used as they are.

  As described above, by installing the humidification unit integrally or separately with the air conditioner and performing the humidification operation simultaneously with the heating operation of the heat pump cycle, in addition to the effects shown in the first to third embodiments, An air conditioner having a humidifying function capable of preventing drying can be obtained. At this time, by setting the input value of the heating means to be smaller than the target set value and gradually approaching the target set value in a predetermined period after the start of the regeneration process, where the relative humidity of the humidified air is likely to be high. The room can be humidified without causing condensation. In addition, it is possible to suppress the heating means control value at the time of start-up of a high load where the compressor consumes most power.

Embodiment 6 FIG.
FIG. 26 is a schematic configuration diagram of an air conditioner having a humidifying function in Embodiment 6 of the present invention.
As described in the fifth embodiment, the air conditioner outdoor unit 200 includes a compressor 201, an outdoor unit heat exchanger 202, an outdoor unit blower 203, an expansion valve 204, a four-way valve 205, and the like, as is well known. Are installed in the indoor unit 400, and an indoor unit heat exchanger 401, an indoor unit blower 402, and the like are connected to each other to form a heat pump cycle.

  In addition to this, the sixth embodiment includes a compressor inverter 201a that controls the operating frequency of the compressor 201, and a load detecting unit 58a that detects an air-conditioning load from a change over time in the operating frequency, and the load detecting unit 58a. The set value previously incorporated in the memory 51 is changed in accordance with the detected value, and the power supply is input to the drive motor 52 of the first blower means 2, the drive motor 53 of the second blower means 3, or the heating means 4. A function for controlling at least one of the power supply means 54 for determining the amount (control value) is added to the control unit 50.

FIG. 27 is a conceptual diagram of a humidification amount control method in Embodiment 6 of the present invention.
A graph 79 shows a time series change of the compressor frequency (Hz) by the compressor inverter 201a, and a set value 80 is a compressor frequency threshold value (Hz _tri ). The set value 80a is a starting operation threshold (Hz _{tri_ini} ), the set value 80b is a high load side threshold (Hz _{tri_h} ), the set value 80c is a low load side threshold (Hz _{tri_l} ), and the set value 81 is a heating means control at start. This is a start-up control value fixed time (t _ini ) that means a time for driving with a constant value (Q). Compressor frequency (Hz), compressor frequency start-up operation threshold 80a (Hz _{tri_ini} ), compressor frequency high load side threshold 80b (Hz _{tri_h} ) and compressor frequency low load side threshold 80b (Hz _{tri_l} ) This means that the heating means control value (Q) is changed, and the humidification amount (W _de ) = dehumidification / humidification amount (W) and the regeneration outlet air relative humidity (Φ _deo ) change. The other parts are the same as those in the first embodiment, and thus the description thereof is omitted.

Next, an example of the operation in the sixth embodiment of the present invention will be described. The basic operation in the configuration of FIG. 26 and the basic control method of the humidification amount shown in FIG. 27 are the same as those in the first embodiment, and thus the description thereof is omitted.
In the heating operation shown in FIG. 26, the first air path switching damper 5 and the second air path switching damper 6 are rotated as shown in the time series change 60 of the heating means control value (Q) shown in FIG. When shifting from the adsorption process to the regeneration process, Q = Q _ini <Q _set is set, and during the control value change time (t _cha ), the heating means control value (Q) is increased stepwise, After t _cha elapses from the damper switching, Q = Q _set is set. Then, the humidification amount (W _de ) = dehumidification / humidification amount (W) gradually increases and reaches W _de = W _set after t _cha elapses from the damper switching, as indicated by the time series change 61, and the regeneration outlet air The relative humidity (Φ _deo ) gradually increases but does not reach 100% RH as indicated by the time-series change 62, and decreases after the passage of t _cha. Therefore, the regeneration outlet air B2 is condensed. It becomes possible to drive without making it.

Here, in the first embodiment, for example, as shown in Table 1, low humidity (FIG. 8: 60% RH) assumption, standard (FIG. 9: 80% RH) assumption, and high according to the relative humidity of the ambient air. The relationship between time (t) and heating means control value (Q) was set for each of the assumptions of humidity (FIG. 10: 90% RH), and settings corresponding to the installation environment, region, etc. were used. However, in the sixth embodiment, an air conditioning load is assumed by the load detecting means 58a from the time series change of the compressor frequency (Hz) as shown in FIG. 27, which is controlled by the compressor inverter 201a. For example, the _setting of a low humidity (60% RH) with a large heating means control value (Q) is assumed at a low load of Hz <Hz _{tri_l} , and a standard (80% RH) is assumed at a standard load of Hz _{tri_l} ≦ Hz <Hz _{tri_l.} In the case of Hz ≧ Hz _{tri_h} , it is preferable to select a setting assuming a high humidity (90% RH) with a small heating means control value (Q). This makes it possible to control the amount of humidification according to the air conditioning load. When the compressor 201 is operating at a high frequency, the heating means control value (Q) becomes small, and the overall power consumption is kept below a certain value. It can be suppressed and useless driving can be prevented.

In particular, at the time of start-up when the operation is restarted after being left for a certain period of time, there is a high possibility that the regeneration outlet air relative humidity (Φ _deo ) will be higher than at the time of normal damper switching. heating means initial control value of the switching time is set to a low Q _ini 0 than Q _ini, similarly controlled value changing time has been set to a long t _cha 0 from t _cha, in the sixth embodiment, described above The start-up operation is determined by the load detection means 58a. That is, as indicated by the time-series change 79, the compressor frequency (Hz) rapidly increases at the time of starting normal heating operation, and then gradually decreases. _Therefore , after the frequency reaches the maximum value, Hz ≦ Hz _{tri_ini} and The time (t _ini ) until this time is regarded as the start-up operation time, and during this period, the heating means control value (Q) is not increased and the operation is fixed at Q = Q _ini 0.

8 to 10 and the set value of the time series change 60 of the heating means control value (Q) in Table 1 are based on the regeneration outlet air B2 immediately after being released from the humidifier. However, as shown in FIG. 23, for example, when the humidifier is installed outside the room and the regeneration outlet air B2 is conveyed by a duct or the like to humidify the room, the regeneration outlet air B2 is cooled in the duct conveyance process. Since the possibility of condensation increases, the control value change time (t _cha ) is longer than the values shown in Table 1, and the heating means control values (Q ₀₁ , Q ₀₂ , Q ₀₃ , Q ₁ , Q ₂ ) are Need to set low.

The method of controlling the humidification amount shown in FIG. 27 is for the case where the air path switching damper switching time (t _dump )> the control value change time (t _cha ), and the heating means control value is always set before the damper switching is performed. (Q) is a control to reach the _set value (Q _set ). However, when t _dump ≦ t _cha , Q is _set to the heating unit initial control value (Q even if Q has not reached Q _set ). Q _ini ) must be set.

However, this air path switching damper switching time (t _dump ) is for optimizing the operation time of the adsorption process and the regeneration process and ensuring a larger amount of humidification per unit time. Although it is shorter than the time (t _cha ), it is highly likely that the regeneration outlet air relative humidity (Φ _deo ) is likely to rise suddenly. It is desirable to set the humidification amount (W _de ) and the regeneration outlet air relative humidity (Φ _deo ) so as to be stable.

FIG. 27 shows an example of the control method based on the heating means control value (Q) as in the first embodiment. However, as in the second embodiment, the regeneration air flow rate (V _de ) is changed to the control value change time. You may reduce in steps during (t _cha ). Furthermore, in addition to the control by the heating means control value (Q) and the regeneration air air volume (V _de), as shown in the first and second embodiments, the suction air air volume (V _ad) for also, the control value change time (t _It may be raised stepwise during _cha ) to reliably prevent condensation in the regeneration outlet air B2.

In the time series change 60 of the heating means control value (Q) in FIG. 27, the change of the heating means control value (Q) is set in a stepwise manner, but may be changed so as to change continuously. A function that monotonously increases the heating means control value (Q) with respect to time is set in the memory 51 in advance, and the control unit 50 reads it out from the set value at the start of operation to the set humidification amount (W _set ). What is necessary is just to control so that a heating means control value (Q) increases continuously with respect to time.

  As described above, assuming the air conditioning load from the operating frequency of the compressor, the input value of the heating means is controlled according to the load, and the input value at the start of heating operation, which is particularly high load, is kept small. In addition to the effects shown in the fifth aspect, it is possible to obtain a necessary amount of humidification according to the load, avoid unnecessary use, and reduce the overall power consumption to a certain value or less.

FIGS. 28 to 29 are flowcharts showing the control method of the sixth embodiment, and the control method of the humidifier will be described based on this flowchart.
When the power is turned on in step S1-1, the control unit 50 drives the first blower drive motor 52, the second blower drive motor 53, and the power supply means 54 of the heating means in step S5-2. At this time, the heating means control value (Q) is set to the starting heating means initial control value (Q _ini 0), which is the minimum value.

In step S5-3, the control unit 50 reads the compressor frequency Hz of the compressor inverter 201a, and in step S5-4, the frequency maximum value Hz _max (initial value is Hz _max = 0) preset in the memory 51 and In comparison, if Hz ≧ Hz _max , the maximum value Hz _max is replaced with the current Hz in step S5-5, and the process returns to S5-3. In S5-4, Hz <Hz _max is satisfied, that is, Hz reaches the maximum value. Repeat S5-3 and S5-4.

After Hz <Hz _max , when compared with the startup operation threshold value Hz _{tri_ini} previously set in the memory 51 in step _S5-6 , if Hz ≧ Hz _{tri_ini} , the process returns to S5-3, and in S5-6 When it is determined that Hz <Hz _{tri_ini} , that is, Hz has decreased and the start-up operation has been completed, the _{process proceeds} to step S5-7.

  In S5-7, it is determined whether or not this step is executed for the first time, and when the startup control is passed for the first time, the time t is reset in Step S5-8, and the control unit 50 in Step S5-9. After the air path switching damper rotation motor 55 is driven to switch the damper, the process proceeds to step S5-10. If it is determined that the second time or later, S5-8 and S5-9 are omitted, the process proceeds to S5-10, and the normal time control after step S5-11 shown in FIG. 29 is performed via S5-10. Proceed to

In S5-11, a low load, a standard load or a high load is determined from the compressor frequency read in S5-3, and the control unit 50 is previously incorporated in the memory 51 in steps S5-12 to S14. Read the relationship table for the humidity assumptions in Table 1 for t ₁ , t ₂ (= t _cha ), t ₃ (= t _dump ), Q ₁ , Q ₂ and Q ₃ (= Q _set ) t _1, t ₂ and the heating means control value corresponding to t ₃ the (Q), respectively set to Q _1, Q ₂ and Q _3.

Next, since the time t is reset in step S5-8 in step S5-15, based on the elapsed time t 'from the damper switching, in steps S5-16 to S18, in steps S5-12 to S14. Using the set values, as in steps S1-12 to S14 of the first embodiment, the values of the elapsed times t ₁ , t ₂ (= t _cha ) and t ₃ (= t _dump ) from the damper switching are used. The power supply means 54 is controlled based on the read heating means control value (Q), and the process returns to S5-3 via step S5-21.

This control is fed back until t ′> t _dump , and when it is confirmed in step S5-15 that the elapsed time t ′ from the damper switching has passed t _dump , the elapsed time t ′ in step S5-19. Is reset, and in step S5-20, the control unit 50 drives the air path switching damper rotation motor 55 to switch the damper. Thereafter, the process returns to S5-3 via S5-21, and S5-4 to S9-9 are omitted if the start-up operation is completed. Therefore, the normal control of S5-11 to S20 is repeated.

In the above description, the humidifying device that controls the heating means control value (Q) of the heating means 4 based on the detection value of the suction air sensor 56 has been described. (V _ad ) or when the regeneration air volume (V _de ) by the second air blowing means 3 in FIG. 13 described in the second embodiment is controlled based on the detection value of the intake air sensor 56, the regeneration outlet air relative The humidity (Φ _deo ) gradually increases but does not reach 100% RH as indicated by the time-series change 62, and decreases after the passage of t _cha, so that the regeneration outlet air B 2 is condensed. It becomes possible to drive without.

This air volume control is the same by changing the heating means control value (Q) in steps S5-12 to S14 and S5-16 to S18 in FIG. 29 to the adsorption air volume (V _ad ) or the regenerative air volume (V _de ). This control method can be used. In addition to controlling one of the heating means control value (Q), the adsorbed air flow rate (V _ad ), or the regeneration air flow rate (V _de ), it is possible to adjust the humidification amount by combining two or more of these. In this case, the operation can be performed without more reliably condensing the regeneration outlet air B2.
