Abstract

PROBLEM TO BE SOLVED: To reduce power consumption, namely, supply energy to a heating means in consideration of the problem that it is necessary to supply a considerable amount of energy to the heating means for heating recirculating air, and power consumption becomes large when electrical energy is used in a dehumidifier using an adsorbent.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an adsorbent which adsorbs moisture in room air on the adsorption side and is heated and dehumidified and regenerated on the regeneration side, and circulating air heated and dehumidified on the regeneration side of the adsorbent. Heat exchanger for exchanging heat with the indoor air, heating means for heating the regeneration side of the adsorbent, a first blower fan for supplying the indoor air to the adsorption side of the adsorbent, and circulating the circulating air And a path for passing indoor air supplied by the first fan to the adsorption side of the adsorbent to be dry air, heating means for circulating air by the second fan, and Having a circulation path for passing the regenerating side of the adsorbent, circulating the high-temperature and high-humidity air through the heat exchanger and exchanging heat with the indoor air, wherein the adsorbent replaces the adsorbing side and the regenerating side, Moisture generated during regeneration is removed by the heat exchanger A dehumidifier that cools with air and collects as dew water, after passing at least a part of the adsorbent on the adsorption side of the adsorbent and circulating air after passing through the heat exchanger to remove heat held by the adsorbent. A circulation path is arranged so as to pass through the heating means, and the circulating air after passing through the heat exchanger deprives the adsorbent of heat when passing through the adsorption side of the adsorbent. As a result, the temperature rises and then passes through the heating means, so that the energy input to the heating means corresponding to the temperature rise, that is, the power consumption can be reduced.

In the circulation path, circulating air flowing from the heating means to the heat exchanger through the adsorbent regeneration side and circulating air returning from the heat exchanger to the heating means through a part of the adsorbent adsorption side to the heating means. The circulation air that has passed through the heating means passes through the adsorbent regeneration side without being mixed with the circulating air that has returned to the adsorption side of the adsorbent. The energy input to the system is efficiently used for the regeneration of the dehumidifier, and the circulating air that has passed through the adsorbent regeneration side is maintained at a high temperature and high humidity without being mixed with the circulating air cooled by the heat exchanger. Then, since the cooling water flows into the heat exchanger, the cooling effect in the heat exchanger is enhanced, and the dew condensation water is efficiently collected.

Further, an introduction portion for guiding the circulating air from the heating means to the regeneration side of the adsorbent and a recirculation portion for recirculating the circulating air from a part of the adsorption side of the adsorbent are integrally formed. Circulating air flowing from the heating means to the regenerating side of the adsorbent and returning to the heating means through a part of the adsorbing side of the adsorbent by filling the gap between the adsorbent and the reflux section. The circulating air that has passed through the heating means passes through the adsorbent regeneration side without being mixed with the circulating air that has returned to the adsorption side of the adsorbent. Therefore, the energy input to the heating means is efficiently used for the regeneration of the dehumidifier, and the circulating air that has passed through the regeneration side of the adsorbent is not mixed with the circulating air that has been cooled by the heat exchanger. State As the cooling water flows into the heat exchanger, the cooling effect in the heat exchanger is enhanced and the dew water is collected efficiently, which has the effect of suppressing the decrease in the amount of dehumidification and increasing the dehumidification efficiency, and also heats the circulation path. Since the inflow port from the means to the adsorbent and the recirculation port from the adsorbent to the heating means can be configured as one part, the number of parts can be reduced. Also, in the heat exchanger, the traveling direction of the circulating air is reversed during the heat exchange with the indoor air,
A circulation path is arranged so that an inflow port of the circulating air into the heat exchanger and an outflow port from the heat exchanger approach in a substantially vertical direction, and a traveling direction of the circulating air during the heat exchange. Inverting the heat exchanger makes the heat exchanger inlet and outlet of the circulating air closer, so that the wind tunnel connecting the heat exchanger and the adsorbent can be configured with a short distance and linearly, and circulates in the heat exchanger. By increasing the air passage distance, the heat exchange efficiency is increased and the size of the heat exchanger can be reduced, so that the size of the main body can be reduced. In addition, the heat exchanger is formed by molding a resin containing a heat transfer promoting substance. By including the heat transfer promoting substance, the heat exchange capacity of the heat exchanger is increased, and the heat exchange side of the adsorbent is regenerated. The circulating air in the high-temperature and high-humidity state passing through the circulating air can be efficiently cooled, and the moisture in the circulating air can be efficiently dew-condensed and collected as dew condensation water. Further, the heating means is divided into an adsorbent heating area for heating the adsorbent and a moisture transport area for transporting moisture desorbed from the adsorbent, so that the regeneration efficiency of the adsorbent is increased, and the adsorbent is located on the adsorption side. After adsorbing moisture at, when the adsorption side and the regeneration side are exchanged and the
First, the adsorbent is heated in the adsorbent heating area to sufficiently release moisture from the surface of the adsorbent, and then the moisture is transported to the regeneration air outlet in the moisture transport area, so the adsorbent can be efficiently regenerated and dehumidification efficiency Has the effect of increasing the Also,
In this configuration, the inlet of the circulating air of the heat exchanger is arranged so as to face the moisture transfer area of the heating means via the adsorbent, and the moisture transfer area and the inlet of the heat exchanger are arranged in a short distance and straight. To reduce the pressure loss in the regeneration air passage and efficiently transport the released moisture.
The dehumidifier can be efficiently regenerated, and has the effect of increasing the dehumidification efficiency. In addition, an air flow opening for protecting the heating means is provided on a dividing plate that divides the moisture conveying area of the heating means and the adsorbent heating area, and a part of the regeneration air flowing to the moisture conveying area is provided. Is caused to flow into the adsorbent heating region, thereby preventing the heating means from being abnormally high in temperature and from being damaged, and having an effect of protecting the heating means. In addition, the heater uses a radiant heat heater as the heating means, and has an effect of efficiently regenerating the adsorbent by effectively using the radiant heat, thereby increasing the dehumidifying efficiency.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the present embodiment, unless otherwise specified, the same parts as those described above are designated by the same reference numerals, and the description thereof will be omitted. Only different parts will be described.

Embodiment 1 FIG. 1 is a schematic view of an adsorbent 104 according to a first embodiment of the present invention. The adsorbent 104 is made of an inorganic material such as ceramic fiber or glass fiber or a mixture of the inorganic fiber and pulp made of an adsorbent material such as silica gel, zeolite or lithium chloride, and a corrugated corrugated paper 2. Are laminated and rolled up to form a disk shape, and have a number of small through holes in the direction of the arrow in the figure to allow ventilation. Adsorbent 10
4 contains relatively high moisture, releases relatively low humidity air, for example, heated air, releases moisture into the passing air and relatively releases the adsorbent when the adsorbent is relatively dry. When air with high humidity, for example, indoor air, passes through, it has the property of adsorbing moisture in the passing air.

FIG. 2 is a view for explaining the principle of the dehumidifying device according to the first embodiment of the present invention. The indoor air sucked into the main body 101 by the first blower fan 107 is supplied to the heat exchanger 105.
Pass while exchanging heat with the circulating air, and pass through the adsorption area 4 on the adsorption side of the adsorbent 104. At this time, the adsorbent 104 adsorbs moisture contained in the room air and simultaneously gives heat of adsorption to the room air. Since the indoor air is reduced in moisture and the temperature is also increased, the indoor air is blown indoors in a state of low relative humidity. On the other hand, the circulating air circulated by the second blower fan 109 is heated by the heating means 106 to a high temperature, passes through the regeneration area 3 on the regeneration side of the dehumidifier 104, and

At this time, since the adsorbent 104 releases the moisture adsorbed in the adsorption area 4 in the regeneration area 3, the circulating air is in a high temperature and high humidity state. The circulating air is cooled to a temperature lower than its dew point temperature by heat exchange with the indoor air in the heat exchanger 105, and condenses the contained moisture. The condensed water is taken out as condensed water. The circulating air that has cooled and condensed moisture passes through the heat recovery area 5 which is a part of the adsorbent 104 on the adsorption side.
Since the heat is stored in the adsorbent 104 itself during the heating in the heat recovery zone 5, the heat recovery area 5 applies heat to the circulating air. The circulated air to which heat has been applied is again blown to the heating means 106 by the second blower fan 109.

With the above configuration, when the circulating air after passing through the heat exchanger 105 passes through the heat recovery area 5 of the adsorbent 104, the temperature rises by depriving the heat stored in the adsorbent 104 of the adsorbent 104. Passing through the means 106, the energy input to the heating means 106 corresponding to the temperature rise,

That is, the high-temperature and high-humidity circulating air passing through the regeneration side of the adsorbent 104 flowing into the first chamber and the heat exchanger 105 flowing into the second chamber.
Since the short circuit with the circulating air in the low temperature state after the cooling is suppressed, the dew water can be efficiently collected in the heat exchanger 105, and the dehumidification efficiency can be improved. The specific values that exert the above effects are the outer ring 17 and the ribs 18.

That is, the circulating air flowing through the heating means 106 flowing into the first opening 25 and the adsorbent 10 flowing into the second opening 26
Since the short circuit with the circulating air that has recirculated a part of the adsorption side of 4 is suppressed, the energy input to the heating means 106 can be efficiently used for the regeneration of the adsorbent 104 and the dehumidification retail can be increased. .

A punching member 41 as a rectifying grid is fixedly installed on the heater frame 38, or installed integrally with the heater frame 38, or integrally formed with the holding plate 24 at a portion where the moisture transfer area 40 of the regeneration air outlet 31 is projected. Installed and adsorbent 1
The circulating air going to the regeneration area 3 of No. 04 is rectified. The suction port 34 of the second blower fan is open in the direction facing the holding plate 24, and the connection duct 30 is interposed between the suction port 34 of the second blower fan and the holding plate 24. A third opening 35 corresponding to the suction port 34 of the second blower fan is opened in a surface of the connection duct 30 in contact with the second blower fan 109, and a second opening is formed in the direction facing the holding plate 24. Since the fourth opening 36 corresponding to 26 is provided, the air flowing out of the second opening 26 is smoothly guided to the suction port 34 of the second blower fan. The actual assembling process includes the second blower fan 109 and the connection duct 3
0 is fixed by screwing, and the suction port 34 of the second blower fan and the third opening 35 of the connection duct 30 are combined to form an independent air path with no gap, and then the outlet 33 of the second blower fan. Is inserted into the regeneration air suction port 32 of the regeneration chamber 29 to form an independent air path with no gap, and then the regeneration chamber 29 and the connection duct 30 are connected to the holding plate 24.
Alternatively, it is fixed to the partition plate 14 or both by screwing. At this time, the regenerating air outlet 31 and the first opening 25 of the holding plate 24 are combined to form an independent air path with no gap, and the fourth opening 3 of the connection duct 30 is formed.
6 and the second opening 26 of the holding plate 24 are combined to form an independent air path with no gap, so that the air is sucked in from the second opening 26 via the connection duct 30 by the second blower fan 109 and reproduced. The first opening 25 is blown out to the chamber 29.
The independent wind path through which is passed is completed. The second blower fan 1
09 and the connection duct 30 may be integrally formed as a single component, and there is no difference in operation and effect. The rotor set 6 is rotating in the direction of the arrow in FIG. 10, and after the adsorbent 104 has absorbed the moisture of the indoor air in the adsorption area 4,
It rotates to the reproduction area 3. In the regeneration area 3, first, the adsorbent 104 is heated by the heat of the heater 28 and the radiant heat at a position facing the adsorbent heating area 39 of the heating means 106. At this time, the moisture adsorbed on the adsorbent 104 is separated from the surface of the adsorbent 104. Next, the moisture transport area 40
In this case, the circulating air rectified by the punching member 41 passes through the adsorbent 104 rotated from the adsorbent heating area 39, so that the adsorbent 1
The water released from the substrate 04 is conveyed toward the first chamber 19 of the partition plate 14.

As described above, the heating means 106 is divided into the adsorbent heating area 39 and the moisture transport area 40.
Adsorbent 10 by increasing the temperature and radiant heat of
4 is promoted, and in the moisture transfer area 40, the wind speed of the circulating air passing through the adsorbent 104 is increased, so that the water desorbed from the adsorbent 104 is conveyed at once, thereby improving the regeneration efficiency of the adsorbent 104. Can be improved.

As shown in FIG. 10, the first connection pipe 20 of the partition plate 14 is disposed facing the inside of the moisture transfer area 40 of the heating means 104 via the adsorbent 104, and The structure is such that it flows straight from the region 40 through the adsorbent 104 into the first connection pipe.

With the above configuration, the circulating air can be blown without increasing the pressure loss in the circulating air passage, and the adsorbent 104 can be blown.
Water that has been removed from the sorbent heating region 39 can be smoothly transported, and the pressure loss increases in the circulating air passage passing through the sorbent heating region 39, so that excess circulating air can be prevented from flowing into the sorbent heating region 39. The effect of dividing the heating means 106 into the adsorbent heating area 39 and the moisture transport area 40 can be further enhanced.

As shown in FIG. 10, the dividing plate 42 is provided with one or a plurality of air circulation ports 43 for protecting the heater 28.

Further, as shown in FIG.
The adsorbent 104 having desorbed water at 0 stores a part of the heat given by the heating means 106, and cannot adsorb water in this state. The adsorbent 104 in the above state rotates to the heat recovery area 5. Heat recovery area 5
Then, the circulating air, which has exchanged heat with room air in the heat exchanger 105 and has a low temperature, passes through the adsorbent 104. At this time, the circulating air is heated by the heat stored in the adsorbent 104 and becomes high temperature.
On the other hand, the moisture in the circulating air passes as it is because the adsorbent 104 cannot adsorb moisture. Heat recovery area 5
The circulating air that has passed through is blown to the heating means 106 by the second blower fan 109. Therefore, the temperature of the circulating air flowing into the heating means 106 can be increased, so that the energy input to the heating means 106 corresponding to the temperature increase, that is, the power consumption can be reduced. In the dehumidifier of the present configuration, the same amount of dehumidification as that of the conventional dehumidifier could be obtained with a heat input of 75 to 80% of that of the conventional dehumidifier.

If a radiation heater, for example, a halogen heater, is used as the heater 28, the adsorbent can be efficiently regenerated by using the radiation heat more effectively, and the dehumidification efficiency can be further improved.

FIG. 11 is a schematic configuration diagram of a heat exchanger 105 for exchanging heat between room air and circulating air that has become hot and humid in the regeneration region 3 of the adsorbent 104. The first, second, and third heat exchangers 44, 45, and 46 are formed by molding a resin material (preferably, polypropylene) by blow molding (or twin-sheet vacuum molding), and circulating air flows in a substantially vertical direction. A circulating air passage air passage 47 is formed, and an indoor air passage air passage 48 through which room air flows in a substantially horizontal direction is formed. On one end face of the first heat exchanger 44, a heat exchanger inlet duct 49 communicating with the circulating air passage 47 is provided, and on the other end face, a first heat exchange connection duct 50a is provided with a heat exchanger inlet duct. 49, and the second heat exchange connection duct 50b is arranged vertically downward as much as possible.
In addition, a third heat exchange connection duct 50c is disposed on an end surface of the second heat exchanger 45 facing the first heat exchanger, at a position facing the first heat exchange connection duct 50a, and The heat exchange connection duct 50d is arranged at a position facing the second heat exchange connection duct, and the fifth heat exchange connection duct 50
e is arranged so as to face the fourth heat exchange connection duct 50d. In addition, a heat exchanger outlet duct 51 is disposed on an end face of the third heat exchanger 46 facing the second heat exchanger 45 at a height vertically adjacent to the heat exchanger inlet duct 49 in a vertical direction, The sixth heat exchange connection duct 50f is arranged at a position facing the fifth heat exchange connection duct 50e. Further, all the heat exchangers have a condensed water outlet 52 formed at the lowermost portion in the vertical direction. The first heat exchange connection duct 50a is connected to the third heat exchange connection duct 50c,
Of the fourth heat exchange connection duct 50d
Is connected to the first heat exchanger 44 and the second heat exchanger 45, and the fifth heat exchange connection duct 50e is connected to the sixth heat exchange connection duct 50f. , These first, second, and third heat exchangers 44, 4
5, 46 are combined. Furthermore, these first, second and third
The heat exchangers 44, 45 and 46 are more securely fixed by screwing at four corners or two corners diagonally. The circulating air flows into the first heat exchanger 44 from the heat exchanger inlet duct 49, and a part of the circulating air flows through the circulating air passage 47 of the first heat exchanger 44 and the room air flowing through the room air passage 48. It flows downward while exchanging heat with the second heat exchanger 45 and flows into the second heat exchanger 45 from the second connection duct 50b. The other circulating air flows into the second heat exchanger 45 through the first connection duct 50a and the third connection duct 50c, and passes through the circulating air passage 47 of the second heat exchanger 45 through the indoor air. It flows downward while exchanging heat with the indoor air flowing through the air passage 48. The first heat exchanger 44 is connected to the fifth connection duct 50e.

Further, the circulating air flows upward through the circulating air passage 47 of the third heat exchanger while exchanging heat with room air flowing through the indoor air passage 48, and flows out of the heat exchanger outlet duct 51. On the assumption of this heat exchange, the circulating air is cooled by the room air, and the moisture in the circulating air is condensed and adheres to the circulating air passage 47 as water droplets. The attached water droplets are passed through the circulating air passage 47.
It flows down inside and is taken out from the condensed water outlet 41. In order to prevent the second connection pipe 22 extending from the partition plate 14 to the heat exchanger outlet duct 51 from interfering with the first heat exchanger 44 and the second heat exchanger 45,

Further, in the circulating air passage 47 of the first heat exchanger 44 and the second heat exchanger 45, the circulating air flows in the downward direction, so that the speed of the circulating air passing therethrough is increased to promote the drop of water droplets adhering to the inside. By doing so, the heat exchange performance can be improved. Since the circulating air flows upward in the circulating air passage 47 of the third heat exchanger 46, it is preferable to reduce the passing air velocity. In this embodiment, the width N of each of the first, second, and third heat exchangers,
By changing O and P, the above-described control of the passing wind speed is realized. That is, the widths N and O of the first and second heat exchangers through which the circulating air flows downward are 15 mm,

As is apparent from the above embodiments, according to the present invention, the circulating air passes through a part of the adsorbent on the adsorbent side to deprive the adsorbent of heat and raise the temperature. Since the adsorbent is regenerated at a high temperature by passing through the means, the energy input to the heating means corresponding to the temperature rise, that is, a dehumidifier having an effect of reducing power consumption can be provided.

The circulating air flowing from the heating means to the heat exchanger through the adsorbent regeneration side and the circulating air returning from the heat exchanger to the heating means through a portion of the adsorbent adsorption side to the heating means are mixed with each other. Because the configuration is limited to

Can be provided.

Further, an introduction part for guiding the circulating air from the heating means to the regeneration side of the adsorbent and a recirculation part for recirculating the circulation air from a part of the adsorption side of the adsorbent are integrally formed. Therefore, it is possible to provide a dehumidifying device that has the effect of improving the accuracy of parts, suppressing the mutual flow of air in the circulation path as much as possible, improving the dehumidifying efficiency, and reducing the cost.

Further, the direction of travel of the circulating air is reversed during the heat exchange with the room air, and the inlet of the circulating air to the heat exchanger and the outlet of the heat exchanger from the heat exchanger are substantially vertically oriented. Since the configuration is such that the circulation path is arranged so as to approach in, the wind tunnel connecting the heat exchanger and the adsorbent can be arranged in a short distance and linearly, so that the passage distance of the circulating air can be secured. It is possible to provide a dehumidifier having an effect of increasing the heat exchange efficiency and reducing the size of the heat exchanger to a compact body size.
