  However, since the water for humidification is collected by condensing the moisture of the outside air, if the absolute humidity of the outside air is low, there is a possibility that sufficient condensation water is not generated and the water for humidification is insufficient. There is. Moreover, since dew condensation water contains the dust of the outside air, the filter which purifies water may be clogged during use.

  Embodiments of the present invention will be described below with reference to the drawings. The following embodiments are specific examples of the present invention and do not limit the technical scope of the present invention.

<Schematic configuration of air conditioner>
FIG. 1 is a configuration diagram of an air-conditioning apparatus according to an embodiment of the present invention. In FIG. 1, the air conditioning apparatus 1 includes a refrigerant circuit 10 through which a refrigerant flows. The refrigerant circuit 10 is formed by connecting a compressor 11, a four-way switching valve 12, an outdoor heat exchanger 13, a first expansion valve 14a, an indoor heat exchanger 15, an accumulator 20, and the like. The refrigerant leaving the compressor 11 flows to either the outdoor heat exchanger 13 or the indoor heat exchanger 15 by the four-way switching valve 12.

  For example, during the heating operation, the control unit 4 causes the four-way switching valve 12 to select the flow path indicated by the solid line in FIG. 1 and causes the refrigerant to flow to the indoor heat exchanger 15. On the other hand, during the cooling operation, the control unit 4 causes the four-way switching valve 12 to select the flow path indicated by the dotted line in FIG. 1 and causes the refrigerant to flow to the outdoor heat exchanger 13. The first expansion valve 14a depressurizes the refrigerant by narrowing the refrigerant flow path. The accumulator 20 accumulates excess liquid refrigerant and returns only the gas refrigerant to the compressor 11.

  The refrigerant circuit 10 further includes an adsorption heat exchanger 116 and a dew condensation heat exchanger 117. The adsorption heat exchanger 116 is connected between the indoor heat exchanger 15 and the first expansion valve 14a, and the dew condensation heat exchanger 117 is connected in parallel with the outdoor heat exchanger 13. Both the outdoor heat exchanger 13 and the dew condensation heat exchanger 117 function as an evaporator, and in particular, the dew condensation heat exchanger 117 is intended to dew moisture in the outside air.

  An adsorption agent mainly composed of zeolite is supported on the surface of the adsorption heat exchanger 116. The adsorbent is not limited to zeolite, but silica gel, activated carbon, organic polymer polymer material having hydrophilicity or water absorption, ion exchange resin material having carboxylic acid group or sulfonic acid group, high temperature sensitivity. It is selected from functional polymer materials such as molecules.

  The refrigerant circuit 10 further includes a second expansion valve 14b and a third expansion valve 14c. The second expansion valve 14b is connected upstream of the refrigerant flow of the condensation heat exchanger 117. Since the second expansion valve 14b further depressurizes the refrigerant decompressed by the first expansion valve 14a, the refrigerant evaporating temperature in the dew condensation heat exchanger 117 is lower than the refrigerant evaporating temperature in the outdoor heat exchanger 13. The temperature of the condensation heat exchanger 117 is lower than the temperature of the outdoor heat exchanger 13. The third expansion valve 14 c is connected between the indoor heat exchanger 15 and the adsorption heat exchanger 116. The third expansion valve 14c serves to depressurize the refrigerant flowing from the indoor heat exchanger 15 to the adsorption heat exchanger 116, but is normally open.

  A humidifying unit 21 is disposed in the vicinity of the indoor heat exchanger 15. The humidification unit 21 gives moderate moisture to the air that passes through the indoor heat exchanger 15 and is blown into the room. Water supplied to the humidifying unit 21 is stored in the tank 23. The water in the tank 23 is water obtained by purifying the dew condensation water generated in the dew condensation heat exchanger 117, and the water is pumped up by the pump 25 and conveyed to the humidification unit 21 through the hose 22. The humidification unit 21 is selected from an ultrasonic humidifier, a heating humidifier, and a spray humidifier.

  In this embodiment, the indoor heat exchanger 15 and the humidification unit 21 are on the indoor unit 3 side, and the others are on the outdoor unit 2 side. The control unit 4 includes a CPU and a memory, and controls each device of the air conditioner 1.

<Outdoor unit 2>
FIG. 2 is a perspective view showing structures of an outdoor unit and a water collecting unit of the air conditioner. In FIG. 2, a water collecting unit 7 that collects moisture from the outside air by condensation is disposed above the outdoor unit 2. The water capturing unit 7 includes an adsorption heat exchanger 116, a dew condensation heat exchanger 117, a drain pan 31 b and a fan 118. The drain pan 31b is positioned below the dew condensation heat exchanger 117, and causes the dew condensation water generated by the dew condensation heat exchanger 117 to flow further downward.

  A vent hole 102 is provided on the wall surface of the water catching unit 7, and an outlet 119 is provided at a position away from the vent hole 102 by a predetermined distance. The fan 118 is a sirocco fan having a high static pressure. When the fan 118 rotates, the outside air is sucked from the vent 102, and the outside air becomes an air flow A, and the adsorption heat exchanger 116 and the condensation heat exchanger 117. And blown out from the air outlet 119. By providing the fan 118, the amount of air passing through the adsorption heat exchanger 116 and the dew condensation heat exchanger 117 can be freely adjusted, and the amount of dew condensation water can be easily controlled.

  In the outdoor unit 2, the compressor 11, the four-way switching valve 12, and the outdoor heat exchanger 13 shown in FIG. In addition, an outdoor fan 81 is also arranged, and sucks outside air by rotating and applies outside air to the outdoor heat exchanger 13 to actively exchange heat with the refrigerant. An air outlet 105 is provided on the wall surface of the outdoor unit 2, and the air exchanged by the outdoor heat exchanger 13 is blown out.

  A water supply unit 26 is arranged below the outdoor unit 2. The water supply unit 26 includes a hose 22, a tank 23 and a pump 25. The water in the tank 23 is pumped up by the pump 25 and conveyed to the humidification unit 21 through the hose 22.

  FIG. 3 is a perspective view of the tank. In FIG. 3, condensed water flows into the inside of the water purification tank 32 from the inlet 32a. A first solenoid valve 33 and a second solenoid valve 34 are connected below the water purification tank 32. The water that has passed through the first electromagnetic valve 33 is discharged from the drain port 51. The water that has passed through the second electromagnetic valve 34 enters the tank 23. A third electromagnetic valve 35 is connected to the bottom surface side of the tank 23, and water that has passed through the third electromagnetic valve 35 is discharged from the drain 51. The pump 25 draws water from the bottom surface side of the tank 23 and sends it to the three-way valve 36, and an appropriate amount of water is supplied from the three-way valve 36 to the humidifying unit 21.

  The water in the tank 23 is irradiated with ultraviolet rays from an ultraviolet lamp 37 for sterilization. Although the ultraviolet lamp 37 is attached to the upper part of the tank 23, since the installation is easy, workability | operativity is good. The sterilizing means is not limited to the ultraviolet lamp 37, and may be, for example, an ozone generator.

  Further, when the air conditioner 1 is installed in a cold region, a heater is disposed in the vicinity of the tank 23 or in the tank 23 in order to prevent the water in the tank 23 from freezing. The heater does not need to be operating at all times, but only when the outside temperature reaches below freezing point.

  The heater may be any heating means that can prevent the water in the tank 23 from freezing. For example, in the case of an electric heater, it is selected from nichrome wire, sheathed heater, carbon heater, ceramic heater, seat heater and the like. It is also possible to select a heat pump type in which piping on the high pressure side (compressor outlet, condenser outlet, etc.) in the refrigeration cycle is heated by being drawn to the lower part of the tank 23 or in the vicinity thereof. Furthermore, two compressors can be connected in parallel, and one compressor can be arranged in the vicinity of the tank 23 to heat the water in the tank 23 by the heat radiation of the compressor.

<Water circulation path>
FIG. 4 is a circuit diagram showing a water circulation path. As shown in FIG. 4, the inside of the water purification tank 32 is partitioned into a first tank 321 and a second tank 322 by a water purification filter 323, and the water that has entered the water purification tank 32 from the drain pan 31b It is stored in the tank 321, then passes through the water purification filter 323 and is stored in the second tank 322. When water passes through the water purification filter 323, impurities such as dust contained in the water are removed by the water purification filter 323.

  When the inside of the first tank 321 is full, the first electromagnetic valve 33 opens the flow path and drains water. The water in the second tank 322 flows into the tank 23 when the second electromagnetic valve 34 opens the flow path. When the tank 23 is full, the second electromagnetic valve 34 closes the flow path. When the water in the tank 23 becomes unnecessary, the third electromagnetic valve 35 opens the flow path and drains it.

  The three-way valve 36 not only supplies the water sent from the pump 25 to the humidifying unit 21 but also returns the water to the second tank 322 of the water purification tank 32 as necessary. By returning water to the 2nd tank 322, since the water after purified water is forced to flow through the purified water filter 323 to the water side before purified water, the purified water filter 323 is cleaned. That is, water flows backward from the second tank 322 to the first tank 321, and impurities accumulated on the surface of the water purification filter 323 are returned to the first tank 321. At this time, when the first electromagnetic valve 33 opens the flow path, the water in the first tank 321 can be discharged while removing impurities accumulated on the water purification filter 323.

  In the present embodiment, since the water catching unit 7 is located above the outdoor unit 2 and sucks in the outside air, the amount of dust contained in the outside air is less than that at the height position of the outdoor unit. Therefore, the rate at which impurities are deposited on the water purification filter 323 is also slow, and the state of the water purification filter 323 is maintained clean for a long time.

<Operation of air conditioner>
The air conditioner 1 can switch between the cooling operation and the heating operation by changing the flow path of the refrigerant with the four-way switching valve 12. This embodiment demonstrates the case where the refrigerant circuit 10 is a circuit for heating operation.

  During the heating operation, the control unit 4 controls the four-way switching valve 12 to select the flow path indicated by the solid line in FIG. 1 and causes the compressor 11 and the indoor heat exchanger 15 to communicate with each other. Since the third expansion valve 14c is normally open, the indoor heat exchanger 15 and the adsorption heat exchanger 116 function as a condenser. The outdoor heat exchanger 13 and the dew condensation heat exchanger 117 function as an evaporator. That is, the high-temperature and high-pressure refrigerant discharged from the compressor 11 is introduced into the indoor heat exchanger 15, and the refrigerant in the indoor heat exchanger 15 is introduced into the adsorption heat exchanger 116 after exchanging heat with indoor air. The refrigerant in the adsorption heat exchanger 116 exchanges heat with the outside air. As a result, the temperature of the refrigerant decreases, and the medium temperature / high pressure state is reached.

  The refrigerant that has exited the adsorption heat exchanger 116 is decompressed by the first expansion valve 14a, part of it is introduced into the outdoor heat exchanger 13, and the rest of the refrigerant is further decompressed by the second expansion valve 14b to the condensation heat exchanger 117. be introduced. Since the control unit 4 controls the second expansion valve 14b to set the evaporation temperature of the refrigerant in the dew condensation heat exchanger 117 to be equal to or lower than the dew point temperature of the outside air, the temperature of the dew condensation heat exchanger 117 is set to the outdoor heat exchanger. The temperature is lower than 13. As a result, even when the dew point temperature of the outside air is low and no dew condensation occurs in the outdoor heat exchanger 13, dew condensation always occurs in the dew condensation heat exchanger 117.

  Further, in the adsorption heat exchanger 116, the refrigerant heats the adsorbent to desorb moisture contained in the adsorbent into the air, so that the air passing through the adsorption heat exchanger 116 is desorbed from the adsorbent. Contains released moisture. Since the moisture also condenses when passing through the condensation heat exchanger 117, the condensation water generated in the condensation heat exchanger 117 is larger than that without the adsorption heat exchanger 116. The refrigerant that has exited the outdoor heat exchanger 13 and the refrigerant that has exited the dew condensation heat exchanger 117 are drawn into the compressor 11 again.

  Since the moisture adsorbed by the adsorbent of the adsorption heat exchanger 116 decreases as the heating time increases, it is preferable to adsorb moisture regularly. In the present embodiment, the refrigerant flow is squeezed periodically by the third expansion valve 14c to depressurize the refrigerant, the refrigerant is evaporated by the adsorption heat exchanger 116, and the adsorbent is cooled. As a result, moisture in the air is adsorbed by the adsorbent.

The air conditioner 1 includes an outdoor unit 2, a water collection unit 7, and a humidification unit 21. The water capturing unit 7 has a condensation heat exchanger 117 that condenses moisture contained in the outside air. The humidifying unit 21 humidifies the room using the condensed water collected by the water collecting unit 7. The water collecting unit 7 is disposed above the outdoor unit 2 and collects condensed water from outside air at a position higher than the outdoor unit 2, and has a dust content higher than that collected from outside air at a height position of the outdoor unit 2.

The water capturing unit 7 further includes an adsorption heat exchanger 116. The adsorption heat exchanger 116 carries an adsorbent that desorbs moisture at a high temperature. The adsorption heat exchanger 116 is connected to the high-pressure side of the refrigerant circuit 10 including the condensation heat exchanger 117 and is disposed in the air flow passage region toward the condensation heat exchanger 117. The adsorption heat exchanger 116 becomes a high temperature as a radiator and the adsorbent desorbs moisture. Since the air passing through the adsorption heat exchanger 116 contains moisture desorbed from the adsorbent, the dew condensation water generated in the dew condensation heat exchanger 117 is increased as compared with the case without the adsorption heat exchanger 116. As a result, a decrease in humidification capacity due to water shortage is prevented.

<Modification>
FIG. 5 is a configuration diagram of an air-conditioning apparatus according to a modification of the embodiment of the present invention. The same components as those in the above embodiment are given the same reference numerals and the description thereof is omitted. In FIG. 5, the air conditioner 101 includes two independent refrigerant circuits 10 and 110. The refrigerant circuit 10 is formed by connecting a compressor 11, a four-way switching valve 12, an outdoor heat exchanger 13, a first expansion valve 14a, an indoor heat exchanger 15, an accumulator 20, and the like.

The refrigerant circuit 10 is used for indoor air conditioning, and the second refrigerant circuit 110 is used for generating condensed water. The control unit 104 includes a CPU and a memory, and controls each device of the air conditioning apparatus 101.

<Operation of air conditioner>
In the second refrigerant circuit 110, the control unit 104 controls the four-way switching valve 112 to select the flow path indicated by the solid line in FIG. 1, and causes the compressor 111 and the adsorption heat exchanger 116 to communicate with each other. That is, the high-temperature and high-pressure refrigerant discharged from the compressor 111 is introduced into the adsorption heat exchanger 116 and exchanges heat with outdoor air, so that the temperature is lowered and the medium temperature and high pressure state is obtained.

  The refrigerant that has exited the adsorption heat exchanger 116 is decompressed by the second expansion valve 14 b and is introduced into the condensation heat exchanger 117. The evaporation temperature of the dew condensation heat exchanger 117 is set to be equal to or lower than the dew point temperature of the outside air in order to dew moisture from the outside air. The dew condensation heat exchanger 117 is disposed downstream of the air flow that has passed through the adsorption heat exchanger 116. In the adsorption heat exchanger 116, since the refrigerant heats the adsorbent to desorb moisture contained in the adsorbent, moisture desorbed from the adsorbent is present in the air passing through the adsorption heat exchanger 116. include. Since the moisture also condenses when passing through the condensation heat exchanger 117, the condensation water generated in the condensation heat exchanger 117 is larger than that without the adsorption heat exchanger 116.

  Since the moisture adsorbed by the adsorbent of the adsorption heat exchanger 116 decreases as the heating time increases, it is preferable to adsorb moisture regularly. In the present modification, the control unit 104 periodically controls the four-way switching valve 112 to select a flow path indicated by a dotted line in FIG. 5 to cause the adsorption heat exchanger 116 to function as an evaporator, thereby cooling the adsorbent.

  When the dew condensation heat exchanger 117 is frosted, the control unit 104 controls the four-way switching valve 112 to select the flow path indicated by the dotted line in FIG. 5 so that the dew condensation heat exchanger 117 functions as a condenser. A high-temperature refrigerant is passed through the heat exchanger 117. The dew condensation heat exchanger 117 is defrosted by the heat radiation of the high-temperature refrigerant. Also at this time, since the adsorption heat exchanger 116 functions as an evaporator, the adsorbent is cooled, and moisture in the air is adsorbed by the adsorbent.

<Features of modification>
The air conditioner 101 includes a refrigerant circuit 10 that is used for indoor air conditioning and a second refrigerant circuit 110 that is used to generate condensed water. The 2nd refrigerant circuit 110 has the adsorption heat exchanger 116 which is a condenser, and the dew condensation heat exchanger 117 which is an evaporator. The air that has passed through the adsorption heat exchanger 116 contains moisture desorbed from the adsorbent, and the moisture is condensed when passing through the condensation heat exchanger 117. For this reason, the dew condensation water which generate | occur | produces in the dew condensation heat exchanger 117 is more than the case where there is no adsorption heat exchanger 116. The condensed water is conveyed to the humidifying unit 21 and used as humidifying water.
