Description

  The present invention relates to an air conditioner capable of performing humidification by humidifying outdoor air and supplying the air indoors.

  Conventionally, many inventions of this type of air conditioner have been devised. Among them, a typical device that is currently widely used as a product is an air conditioner equipped with a humidifying device shown in Patent Document 1, while rotating a rotor made of an adsorbent while in outdoor air. Moisture is adsorbed, heated and separated to obtain air with high humidity, and the operation of sending it into the room is performed continuously for humidification (see, for example, Patent Document 1).

  FIG. 4 shows the configuration of an air conditioner equipped with a conventional air conditioner humidifier described in Patent Document 1. As shown in FIG. 4, the air conditioner includes an indoor unit 101 including an indoor heat exchanger 102 and an indoor fan 103, a compressor 107, a four-way valve 109, an outdoor heat exchanger 105, an outdoor fan 106, and an expansion valve 108. The outdoor unit 104 includes a humidifier 300.

  The humidifier 300 includes an adsorption rotor 301 in which a material that adsorbs water vapor such as zeolite is formed into a honeycomb rotor, a drive belt 302, a drive motor 303, blowers 304 and 305, and a heater 306.

A refrigerant cycle 116 in FIG. 4 shows a heating state, and flows in the directions of arrows 116 a, 116 b, 116 c, 116 d, and 116 e, and the high-temperature and high-pressure refrigerant compressed by the compressor 107 passes through the four-way valve 109 to the room. The heat exchanger 102 condenses and heats the room 100. The refrigerant condensed in the indoor heat exchanger 102 is decompressed and expanded by the expansion valve 108, vaporized by the outdoor heat exchanger 105, returns to the compressor 107 through the four-way valve 109.
The air blowers 304 and 305 form separate air passages, and the air passage 307 of the air blower 304 is for adsorbing water vapor in the outside air to the adsorption rotor 301, and the outside air taken into the device is an arrow. It flows in the direction of 304a, passes through the adsorption rotor 301, is deprived of humidity, and is released again to the outside as indicated by an arrow 304b.

  The humidified air conveyance path 117 through which the humidified air is sent by the blower 305 is for separating the moisture adsorbed by the adsorption rotor 301 and conveying the humidified air. The outside air taken into the apparatus is heated by the heater 306. Then, the moisture of the adsorption rotor 301 is released to become high humidity air. Then, the air is sucked into the blower 305, flows in the directions of arrows 306a and 305a, is transported to the indoor unit 101, and humidifies the room 100.

As other humidification technologies, there are other technologies such as spraying water on the carrier air as in Patent Document 2, and technologies for transporting the drain water of the outdoor unit to the indoor unit and naturally vaporizing and humidifying it as in Patent Document 3. is there.
Japanese Patent No. 3559421 Japanese Examined Patent Publication No. 60-53823 Japanese Patent No. 2919711

However, in the conventional configuration, in the technology of spraying water on the carrier air or the technology of transporting the drain water of the outdoor unit to the indoor unit and naturally vaporizing and humidifying, there is a concern about the growth of gonococci and algae. And problems such as clogging of the conveyance path.
Moreover, in the technique using an adsorption | suction rotor, it has the subject that two fans and an adsorption | suction rotor require a big volume, and an apparatus enlarges. Furthermore, the technique for spraying water on the carrier air also has a problem that the space for spraying is necessary and the reason is the same, although the reason is different.
Further, in the technique using the adsorption rotor, the heated air must have the amount of heat for detachment because the moisture is desorbed by the heated air. Therefore, in order to increase the humidification amount, it is necessary to increase the temperature of the heated air or increase the carrier air.
In reality, there is an upper temperature limit due to the device configuration, so a large amount of carrier air is required for the amount of humidification, and accordingly, there is a problem that the cross-sectional area of the conveyance path becomes large and the installation workability deteriorates. Have.

  The present invention solves the above-mentioned conventional problems, and is free from problems such as sanitary problems due to the propagation of gonococci and algae and problems such as clogging of the conveyance path, and is an air conditioner having a humidification function that is small and excellent in installation workability. The purpose is to provide a machine.

  In order to solve the above-described conventional problems, an air conditioner of the present invention includes an outdoor unit, a water vapor generating unit that heats water to generate water vapor, an air heating unit that heats outdoor air, and the water vapor generating unit. And a humidified air conveying means for sending humidified air having a high absolute humidity and a high temperature obtained by mixing the water vapor generated by the means and the heated air generated by the air heating means to the indoor unit.

  As a result, air and water can be sterilized by heating, and it can be composed of only two small heating means and one humidified air conveying means, creating high-temperature and high-humidified humidified air in a small cross-sectional area conveying path. Can be transported.

  Since the air conditioner of the present invention can sterilize air and water by heating, it can prevent the propagation of gonococci and algae and clog the conveyance path, and can realize a hygienic and highly reliable humidification function. Moreover, since it can be comprised only with two small heating means and one humidified air conveyance means, a small apparatus can be provided. Furthermore, since high-temperature and high-humidity humidified air can be generated and transported through a transport path having a small cross-sectional area, excellent workability can be realized.

Air heating means, and humidified air conveying means for sending humid air having high temperature and high absolute humidity obtained by mixing water vapor generated by the water vapor generating means and heated air generated by the air heating means to the indoor unit With By humidifying the indoor air, the air and water can be sterilized by heating, and it can be composed of only two small heating means and one humidified air conveying means, and high-humidity humidified air can be obtained. Therefore, since a large amount of moisture can be transported even on a transport path having a small cross-sectional area, it is possible to provide a humidifying function that is hygienic and highly reliable, and can provide a compact and excellent workability device.

In the second invention, in particular, the humidified air conveying means of the first invention sends the outdoor air to the air heating means, and mixes the heated outdoor air and the water vapor generated by the water vapor generating means.

  In particular, the fourth invention includes humidified air heating means for heating the humidified air in the downstream of the humidified air conveying means of the third invention, and the temperature of the humidified air is increased and conveyed to the indoor unit. Thus, the temperature of the humidified air after the humidified air conveying means is raised to prevent condensation, or the temperature of the humidified air sucked into the humidified air conveying means is lowered and the temperature immediately before leaving the outdoor unit is increased.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 shows a configuration diagram of an air conditioner according to a first embodiment of the present invention.

As shown in FIG. 1, the air conditioner according to the first embodiment includes an indoor unit 101 including an indoor heat exchanger 102 that is an indoor heat exchanger and an indoor fan 103 that is an indoor fan, and a compressor 107. The outdoor unit 104 includes a four-way valve 109, an outdoor heat exchanger 105 that is an outdoor heat exchanger, an outdoor fan 106 that is an outdoor fan, an expansion valve 108 that is a throttle, and a humidifier 200. In FIG. 1, the refrigerant cycle 116 indicates a heating state and flows in the directions of arrows 116 a, 116 b, 116 c, 116 d, 116 e, and the compressor 107
The high-temperature and high-pressure refrigerant compressed in step 4 is condensed in the indoor heat exchanger 102 through the four-way valve 109 to heat the room 100. The refrigerant condensed in the indoor heat exchanger 102 is decompressed and expanded by the expansion valve 108, vaporized by the outdoor heat exchanger 105, returns to the compressor 107 through the four-way valve 109.

  During the defrosting operation or the cooling operation, the four-way valve 109 is switched so that the refrigerant flows from the four-way valve 109 sequentially to the four-way valve 109 through the outdoor heat exchanger 105 and the indoor heat exchanger 102.

  In the case of a dedicated heating machine or the like, the four-way valve 109 is not always necessary.

  The humidifying device 200 includes a steam unit 110 that is a steam generation unit including a heater 114, an air heating unit 111 that is an air heating unit including a heater 115, a blower 112 that is a humidified air conveying unit, and a humidification control unit 131. It is configured. Then, the moisture condensed in the outdoor heat exchanger 105 is supplied to the steam unit 110, heated to become steam, and flows in the direction of the arrow 114a. On the other hand, outside air is taken in by the blower 112 in the direction of arrow 112a, heated by the air heating unit 111, flows in the direction of arrow 115a, mixes with water vapor, flows in the humidified air conveyance path 117 in the direction of arrow 118a, and the indoor unit 101. To the room 100.

  Since the steam unit 110 hits the downstream side when viewed from the blower 112 and the steam flows in the direction of the arrow 114a, the steam unit 110 has a sealed structure. Therefore, the condensed water in the outdoor heat exchanger 105 is forcibly supplied by the water supply pump 113.

  Furthermore, the indoor unit 101 is provided with an indoor temperature / humidity sensor 119, and the outdoor unit 104 is provided with an outdoor temperature / humidity sensor 121, and temperature / humidity signals 120 and 122 are sent to the humidification control unit 131, respectively. The humidification control unit 131 determines the outputs 123, 124, and 125 of the heaters 114 and 115 and the blower 112 from the on / off of the humidification operation, the indoor target humidity, the temperature / humidity signals 120 and 122, and the like.

  In the steam unit 110, the condensed water supplied by the water supply pump 113 is heated and boiled by the heater 114 to form water vapor, so that it is sterilized and sanitary. Also in the air heating unit 111, if the air is heated to a temperature exceeding 100 ° C., dew condensation can be prevented and a good sanitary state can be obtained. In this respect, the present invention is superior to a technique for transporting water with liquid and vaporizing or a technique for spraying water.

  Furthermore, since the steam unit 110 and the air heating unit 111 can use the heaters 114 and 115 with high output density, they can be configured with a small volume. Furthermore, since the humidified air conveying means can also be constituted by only one of the blowers 112, a compact device is constituted as compared with the adsorption-type technology using a suction fan as well as a bulky adsorbent rotor and conveying. can do.

Further, in the adsorption type, all the heat necessary for detachment of moisture is carried by heated air. The amount of heat required for the release of moisture is almost similar to the latent heat of water, and zeolite having a high adsorption capacity requires a little more heat than the latent heat of water. For example, when 100 g of water is mixed with 1 kg of dry air to create moist air (dew point is about 53 ° C.), the latent heat of water is 2300 J / g and the specific heat of air is 1.006 J / (g · K). In order to release water, the air needs to be at least 229 ° C. or higher. If the temperature of the humidified air is set to 100 ° C. to prevent dew condensation, the temperature of the air before contacting the adsorption rotor needs to be at least 330 ° C., and the materials used are limited and the configuration of the apparatus is difficult.
To avoid this, the amount of air used for moisture removal is increased and the temperature of the air is lowered. As a result, the total mass of humidified air to be transported increases, and a duct having a large cross-sectional area commensurate with this is required.
On the other hand, in the present invention, since the amount of water vapor generated in the steam unit 110 can be controlled by the output of the heater 114, high-temperature and high-humidity humidified air can be easily produced. Therefore, the total mass of the humidified air to be conveyed can be reduced, and a duct having a small cross-sectional area can be used, so that excellent workability can be realized.
In addition, since the blower 112 is upstream of the air heating unit 111, high-temperature or high-temperature and high-humidity air does not pass through the blower 112, so that deterioration due to heat of the blower 112 can be prevented and heat loss can be reduced.

  Further, when the distance between the indoor unit 101 and the outdoor unit 104 is increased, the resistance when the humidified air is transported increases, and when the output of the blower 112 is the same, the amount of transported air decreases, so the dew point of the humidified air increases. The outlet temperature is lowered and condensation tends to occur. Therefore, if the outputs of the blower 112 and the heater 115 of the air heating unit 111 are increased, condensation can be prevented and humidification can be performed with high reliability.

  Conversely, when the distance between the indoor unit 101 and the outdoor unit 104 is shortened, the amount of air transported increases and the decrease in the outlet temperature decreases, so the outputs of the blower 112 and the heater 115 become larger than necessary. When the output is lowered, efficient humidification can be performed.

  When the detected value of the indoor temperature / humidity sensor 119 is significantly smaller than the target humidity, the output of the heater 114 installed in the steam unit 110 is increased to increase the amount of humidification, and when the detected value is slightly lower, the output of the heater 114 is decreased. If the amount of humidification is reduced, the controllability is improved and a comfortable temperature and humidity environment can be obtained. Incidentally, when the detected value of the indoor temperature / humidity sensor 119 exceeds the target humidity, it is desirable not to perform humidification.

  Moreover, since the actual humidification amount changes not only with the output of the heater 114 but also with the temperature and humidity of the outside air, when the absolute humidity of the outside air is high, the output of the heater 114 is given in the same manner as when the humidity is low. The dew point of the humidified air becomes high and condensation tends to occur. Therefore, in consideration of the detection value of the outdoor temperature / humidity sensor 121, if the output of the heater 114 is reduced when the absolute humidity of the outside air is high, dew condensation can be prevented and highly reliable humidification can be performed.

  As described above, in the present embodiment, water vapor generating means for generating water vapor by heating water to the outdoor unit, air heating means for heating outdoor air, water vapor generated by the water vapor generating means, Humidified air conveying means for sending humid air having a high temperature and high absolute humidity obtained by mixing the heated air generated by the air heating means to the indoor unit, and humidifying the indoor air, thereby It can be sterilized by heating, can be configured with only two small heating means and one humidified air conveying means, and high temperature and high humidity humidified air can be obtained, so a large amount of moisture is conveyed even in the small cross-sectional area conveying path Therefore, a hygienic and highly reliable humidification function can be realized, and a small and excellent workability apparatus can be provided.

  Further, the humidified air conveying means sends the outdoor air to the air heating means, and the humidified air obtained by mixing the heated outdoor air and the water vapor generated by the water vapor generating means to the indoor unit. By carrying, high-temperature air or water vapor does not pass through the humidified air conveying means, so the humidified air conveying means is not deteriorated by heat, heat loss can be reduced, and reliability is high and efficient. A good device can be provided.

  Further, by adjusting the output of the humidified air conveying means and the air heating means and the humidified air heating means according to the distance for conveying the humidified air, a predetermined amount of humidified air is conveyed even if the conveying distance changes. In addition, it is possible to avoid the reduction of the maximum humidification amount and the excessive amount of conveyance, perform highly reliable and efficient humidification, and realize efficient humidification with stable capacity.

  In addition, an indoor temperature / humidity detecting means for detecting the indoor temperature and humidity is provided, the humidification amount is determined according to the difference between the target humidity and the detected humidity of the indoor temperature / humidity detecting means, and the output of the water vapor generating means is adjusted. By doing so, the responsiveness of humidity control can be improved, and excellent comfort can be obtained.

  The outdoor temperature / humidity detection means for detecting the outdoor temperature and humidity is further provided, and the humidification amount is determined as the indoor target temperature / humidity, the indoor temperature / humidity detected by the indoor temperature / humidity detection means, and the outdoor By calculating from the outdoor temperature and humidity detected by the temperature and humidity detection means, even if the absolute humidity of the outdoor air changes, the absolute humidity of the humidified air is accurately controlled, and the target humidification amount can be controlled. It is possible to prevent the humidity of the humidified air from becoming too high and cause dew condensation, and a highly reliable device for dew condensation in the transport path can be obtained.

In this embodiment, the condensed water generated in the outdoor heat exchanger 105 is used for humidification. However, a configuration in which water is manually supplied or automatically supplied from the water supply is also possible. However, when manually supplying water, the humidification operation is stopped or interrupted, or a separate water tank is provided, and water is supplied manually to the water tank and then automatically supplied to the steam unit 110 from there. There is a need.
(Embodiment 2)
FIG. 2 shows a configuration diagram of an air conditioner according to the second embodiment of the present invention.
As shown in FIG. 2, the air conditioner according to the second embodiment includes an indoor unit 101 including an indoor heat exchanger 102 that is an indoor heat exchanger and an indoor fan 103 that is an indoor fan, and a compressor 107. The outdoor unit 104 includes a four-way valve 109, an outdoor heat exchanger 105 that is an outdoor heat exchanger, an outdoor fan 106 that is an outdoor fan, an expansion valve 108 that is a throttle, and a humidifier 200.

  The portions other than the humidifying device 200 are exactly the same as those in the first embodiment, and a different humidifying device 200 inside will be described.

  As shown in FIG. 2, the humidifying device 200 according to the second embodiment includes a steam unit 110 that is a steam generation unit including a heater 114, an air heating unit 111 that is an air heating unit including a heater 115, and humidified air. It consists of a blower 126 and a humidification control unit 131 which are conveying means. The difference from the first embodiment is that the blower 126 is disposed downstream of the steam unit 110 and the air heating unit 111 at a position after the steam and the heated air are mixed to become humidified air.

  Since the blower 126 is disposed downstream, the steam unit 110 and the air heating unit 111 have negative pressure. The air heating unit 111 does not change, but the steam unit 110 has a negative pressure, so that even if the steam unit 110 has an opening, water vapor does not leak. Therefore, the water supply pump 113 provided in the first embodiment of FIG. 1 is not required, and the configuration is simple. Further, when water is supplied manually, it is not necessary to give special consideration.

  In addition, the second embodiment can prevent dew condensation and obtain a good hygiene state, can constitute a small device, and has excellent workability by using a duct having a small cross-sectional area. What can be realized is the same as in the first embodiment.

Furthermore, if the output of the fan 126 and the heater 115 of the air heating unit 111 is changed according to the distance between the outdoor unit 104 and the indoor unit 101, condensation can be prevented and highly reliable humidification can be achieved. Depending on the difference between the detected value of 119 and the target humidity, the steam unit 11
It is possible to change the output of the heater 114 installed at 0 to obtain a comfortable temperature and humidity environment, and to determine the humidification amount and adjust the output of the heater 114 in consideration of the detection value of the outdoor temperature and humidity sensor 121. Thus, it is the same as in the first embodiment that condensation can be prevented and humidification can be performed with high reliability.

  As described above, in the present embodiment, the humidified air transporting means uses the humidified air obtained by mixing the outdoor air heated by the air heating means and the steam generated by the steam generating means. By sucking and transporting to the indoor unit, there is no fear that the water vapor generating means has a negative pressure and the water vapor leaks, so that the water vapor generating means can be sealed and the water supply device can be omitted. The apparatus can be configured with a simple configuration.

In the air conditioner according to the second embodiment, the condensed water generated in the outdoor heat exchanger 105 is used for humidification as in the first embodiment. However, water is supplied manually or automatically from the water supply. It is also possible to provide a configuration that supplies them automatically. Here, in this Embodiment 2, when performing water supply manually, it is not necessary to stop or interrupt a humidification driving | operation.
(Embodiment 3)
FIG. 3 shows a configuration diagram of an air conditioner according to the third embodiment of the present invention.
As shown in FIG. 3, the air conditioner according to the third embodiment includes an indoor unit 101 including an indoor heat exchanger 102 that is an indoor heat exchanger and an indoor fan 103 that is an indoor fan, and a compressor 107. The outdoor unit 104 includes a four-way valve 109, an outdoor heat exchanger 105 that is an outdoor heat exchanger, an outdoor fan 106 that is an outdoor fan, an expansion valve 108 that is a throttle, and a humidifier 200.

  The portions other than the humidifying device 200 are exactly the same as those in the first and second embodiments, and the humidifying device 200 is also supplied with the humid air in the downstream (downstream) of the fan 126 in the second embodiment. A humidified air heating unit 128 which is humidified air heating means for heating is provided.

  The humidified air heating unit 128 is provided with a heater 129 that is controlled by receiving the output 130 from the control unit 131, and reheats the humidified air sent from the blower 126. Accordingly, the temperature immediately before the outdoor unit outlet of the humidified air conveyance path can be raised while keeping the blower 126 below the temperature at which it deteriorates due to heat, so the temperature difference between the humidified air temperature and the dew point can be increased. It is easier to prevent condensation.

  Moreover, since the temperature of the humidified air passing through the blower 126 is not required to reach the dew point, it can be easily set to a temperature that does not cause thermal degradation. In addition, since heat loss in the blower 126 can be suppressed, it is also effective from the viewpoint of reliability of the blower 126 and suppression of heat loss.

  The third embodiment can prevent dew condensation and obtain a good hygiene state, can constitute a small device, and has excellent workability by using a duct having a small cross-sectional area. What can be realized is the same as in the first and second embodiments.

  Furthermore, if the output of the fan 126 and the heater 115 of the air heating unit 111 is changed according to the distance between the outdoor unit 104 and the indoor unit 101, condensation can be prevented and highly reliable humidification can be achieved. The output of the heater 114 installed in the steam unit 110 can be changed according to the difference between the detected value of 119 and the target humidity to obtain a comfortable temperature / humidity environment, and the detected value of the outdoor temperature / humidity sensor 121 is also taken into consideration. As in the first and second embodiments, the humidification amount is determined and the output of the heater 114 is adjusted to prevent condensation and to perform highly reliable humidification.

  As described above, in the present embodiment, humidified air heating means for heating the humidified air is provided downstream of the humidified air conveying means, and the temperature of the humidified air is increased and conveyed to the indoor unit. Therefore, the temperature of the humidified air after the humidified air conveying means is raised to prevent condensation, and the temperature of the humidified air sucked into the humidified air conveying means is lowered to keep the temperature just before leaving the outdoor unit high. By doing so, it is possible to prevent thermal deterioration of the humidified air conveying means and suppress heat loss, increase the humidity of the humidified air, increase the conveying distance from the outdoor unit to the indoor unit, The efficiency can be improved, and efficient humidification can be performed.

  In the air conditioner according to the third embodiment, the condensed water generated in the outdoor heat exchanger 105 is used for humidification as in the second embodiment, but water is supplied manually or automatically from the water supply. It is also possible to provide a configuration that supplies them automatically. Further, when water is supplied manually, it is not necessary to stop or interrupt the humidification operation, as in the second embodiment.

  As described above, the air conditioner according to the present invention has a humidifying function for bringing moisture from the outside, can realize a hygienic and highly reliable humidifying function, and can provide a small-sized device. Therefore, it can be widely applied to air conditioners that perform humidification, such as air conditioners and ventilators.
