  The water supply / drainage device 32 may be provided with a drainage valve (not shown) composed of, for example, an electromagnetic valve so that the water in the drain pan 32b can be drained.

<Configuration of indirect vaporization element>
FIG. 3 is an explanatory view showing an outline of the indirect vaporization element 10, FIG. 3A is an overall configuration of the indirect vaporization element 10, FIG. 3B is a main configuration of the indirect vaporization element 10, and FIG. The cooling principle is shown.

  As shown in FIG. 3B, the indirect vaporization element 10 includes a dry cell 33 having a plurality of first flow paths 33b partitioned by a partition 33a, and a plurality of second flow paths 34b partitioned by the partition 34a. A wet cell 34, and a dry cell 33 and a partition wall 35 that partitions the wet cell 34.

  The dry cell 33 and the wet cell 34 are stacked with the partition wall 35 interposed therebetween so that the first flow path 33b and the second flow path 34b are orthogonal to each other.

  As shown in FIG. 3 (c), the partition wall 35 includes a moisture-proof film 35a formed of a polyethylene film or the like, and a wet layer 35b formed of pulp or the like. The moisture-proof film 35a faces the dry cell 33, and the wet layer 35 b faces the wet cell 34.

  In addition, as shown in FIG. 3B, the partition wall 35 is formed with a vent hole 35c that allows a part of the first flow path 33b and the second flow path 34b to communicate with each other. Further, as shown in FIG. 3A, a closed portion 36 is formed at the outlet of the first flow path 33b in which the vent hole 35c is formed, and is configured so that air does not pass through.

  Thereby, in the indirect vaporization element 10, the working air flow path 10a is connected to the first flow path 33b, the vent hole 35c, and the second flow path from the suction port of the first flow path 33b in which the vent hole 35c is formed. It passes through 34b and communicates with the outlet of the second flow path 34b. Further, the product air flow path 10b communicates from the suction port of the first flow path 33b in which the vent hole 35c is not formed, through the first flow path 33b to the outlet of the first flow path 33b.

  The outline of the cooling principle by the indirect vaporization element 10 will be described with reference to FIG. Here, the working air WA and the product air PA flow in directions orthogonal to each other, but in FIG. 3C, the flowing directions of the working air WA and the product air PA are illustrated in parallel.

  Water is supplied to the wet layer 35b facing the working air channel 10a by the water supply / drainage device 32 shown in FIG. Thereby, moisture is vaporized by the temperature difference between the working air WA passing through the working air flow path 10a and the wet layer 35b, and the working air WA is cooled.

  When the working air WA is cooled, the product air PA passing through the product air channel 10b partitioned by the working air channel 10a and the partition wall 35 is cooled by receiving cold heat through the partition wall 35.

  Here, since the moisture-proof film 35a constituting the partition wall 35 does not pass moisture, the absolute humidity does not change even if the product air PA passes through the product air flow path 10b. Note that the working air WA becomes highly humid when it passes through the working air channel 10a.

  As an example, when the input temperature of the product air PA and the working air WA is 30 ° C., the absolute humidity is 10 g / kg (DA: dry air), and the relative humidity is about 40% RH, the outlet temperature of the product air PA is 20 ° C. Go down. The relative humidity increases to about 70% RH because the temperature decreases, but the absolute humidity is 10 g / kg (DA) and does not change.

  Further, the outlet temperature of the working air WA is lowered to 23 ° C. However, the absolute humidity increases to 16 g / kg (DA).

<Installation example of air conditioning system>
FIG. 4 is a configuration diagram illustrating an installation example of the air conditioning system 1 according to the present embodiment. Next, a configuration of a building in which the air conditioning system 1 is installed will be described. The building 51 is a detached house, for example, and the air conditioning system 1 is installed outdoors. The hybrid solar collector 2 of the air conditioning system 1 is installed in a direction in which the sunlight S is always incident as much as possible, for example, southward, as shown in FIG.

  In the air conditioning system 1, the hybrid solar collector 2 and the indirect vaporizer 3 may be configured integrally or separately, but the orientation of the hybrid solar collector 2 is adjusted. Considering the above, it is better to configure separately.

  In the indirect vaporization air conditioner 3, the air supply port 25 shown in FIG. 1 is connected via a duct 53 and an air supply grill 52 attached to a wall surface, a ceiling surface, or the like of a building 51. In addition, the exhaust port 26 is connected to an exhaust grill provided in a casing (not shown) of the indirect vaporization air conditioner 3 so as to exhaust to the outdoors.

  Further, the outside air introduction opening 16 of the hybrid solar heat collector 2 is provided in the case main body 11 shown in FIG. 1 and is connected to an intake grill (not shown) having a filter and the like. Furthermore, the suction port of the outside air supply fan 28 connected to the outside air suction port 20 of the indirect vaporization air conditioner 3 is provided in a housing (not shown), and is connected to an intake grille having a filter or the like so that outside air can be taken in. To do.

<Cooling operation example of air conditioning system>
FIG. 5 is a configuration diagram showing an air flow during cooling in the air conditioning system 1 of the present embodiment. Next, an operation during cooling of the air conditioning system 1 will be described.

  First, when performing a cooling operation, in the indirect vaporization air conditioner 3, the flow path switching damper 27 a is driven to connect the regeneration air outlet 22 and the processing air outlet 23 to the exhaust outlet 26, and the flow path switching damper. 27 b is driven to allow the cooling air outlet 24 to communicate with the air inlet 25.

  6 and 7 are configuration diagrams showing an operation example of the hybrid solar heat collector 2. In the hybrid solar heat collector 2, the regeneration air supply fan 29 is driven, so that the outside air sucked from the outside air introduction opening 16 passes through the air flow path 5 and flows toward the warm air outlet 17. Is generated.

  Moreover, the water which passes along the piping 4 with a fin circulates by the circulation pump 15 being driven. Here, in the finned pipe 4, when the circulating pump 15 is driven so that water is supplied from the first connecting portion 13 b side and drained from the second connecting portion 13 a side, as shown in FIG. The water flow in 4 is in the direction indicated by arrow A1. The air flow in the air passage 5 communicating with the warm air outlet 17 is in the direction indicated by the arrow B, and the water flow in the finned pipe 4 is opposed to the air flow. This flow of water is called countercurrent.

  On the other hand, in the finned pipe 4, when the circulation pump 15 is driven so that water is supplied from the second connection portion 13 a side and drained from the first connection portion 13 b side, as shown in FIG. The flow of water in the attached pipe 4 is in the direction indicated by the arrow A2. The air flow in the air flow path 5 communicating with the warm air outlet 17 is in the direction indicated by the arrow B, and the water flow in the finned pipe 4 is in the same direction as the air flow. Such a flow of water is called a parallel flow.

  Now, as shown in FIG. 2, when the sunlight S enters the hybrid solar collector 2, the sunlight S irradiates the finned pipe 4. Thereby, the water which flows through the piping 4 with a fin is warmed. Further, the air flowing through the air flow path 5 is also warmed.

  Further, when the water flowing through the finned pipe 4 is warmed, the finned pipe 4 dissipates heat. Here, since the finned pipe 4 is provided with the fins 4a, the heat transfer area is wide. Thereby, heat can be efficiently transmitted to the air flowing through the air flow path 5, and the air flowing through the air flow path 5 is further warmed.

  Thereby, in the hybrid solar collector 2, both hot water and warm air are generated using solar energy.

  Here, in the hybrid solar collector 2, the water flowing through the finned pipe 4 and the air flowing through the air passage 5 are warmed by solar energy, and further, the heat flowing through the finned pipe 4 flows through the air passage 5. Since air is further warmed, heat collection efficiency is high.

  In particular, the hybrid solar collector 2 of the present example can lengthen the air flow path 5 by providing the partitioning portion 18, and when the air flow path 5 becomes longer, the air passing through the air flow path 5 becomes solar. The time to irradiate the light S and the time to contact the finned pipe 4 are increased, and the amount of heat received increases, improving the heat collection efficiency.

  That is, in the configuration in which the partition portion 18 is not provided, it is necessary to provide the outside air introduction opening 16 in the side portion of the case main body 11 that faces the warm air extraction opening 17. On the other hand, by providing the partition portion 18, the outside air introduction opening 16 and the warm air extraction opening 17 can be provided on the same side of the case main body portion 11, and the length of the same case main body portion 11 is doubled. The air flow path 5 having a certain length can be secured.

  In addition, when the water flow is a countercurrent type as shown in FIG. 6 and a parallel flow type as shown in FIG. 7, the cocurrent type has higher heat collection efficiency of water and air. .

  The total heat collection efficiency of water and air is about 80 to 90 percent for the counterflow type and about 95 percent for the cocurrent type, and a very high total heat collection efficiency of water and air is obtained.

  In the indirect vaporization air conditioner 3, when the outside air supply fan 28 is driven, an air flow from the outside air inlet 20 toward the cooling air outlet 24 and the processing air outlet 23 is generated.

  In the indirect vaporization air conditioner 3, since the outside air inlet 20 communicates with the dehumidification flow path 31a of the dehumidification unit 6, the outside air OA flows through the dehumidification flow path 31a when the outside air supply fan 28 is driven.

  In addition, the regeneration channel 31 b of the dehumidifying unit 6 communicates with the regeneration air suction port 21. The regenerative air inlet 21 communicates with the warm air outlet 17 of the hybrid solar collector 2 via the regenerative air supply fan 29. As a result, the regeneration air supply fan 29 is driven, and warm air heated by the hybrid solar collector 2 flows as regeneration air in the regeneration flow path 31b.

  In the dehumidifying unit 6, the outside air passing through the dehumidifying channel 31 a is dehumidified by adsorbing moisture to the dehumidifying rotor 8. When the dehumidification rotor 8 is driven to rotate, the portion that has adsorbed moisture moves to the regeneration channel 31b side.

  The heater 9 provided in the regeneration channel 31 b is supplied with hot water heated by the hybrid solar collector 2 by the circulation pump 15 via the external pipe 14. Thereby, the regenerated air passing through the regenerating flow path 31 b is further heated by the heater 9 and passes through the dehumidifying rotor 8. The dehumidification rotor 8 is regenerated to a state where moisture is evaporated by allowing the heated regeneration air to pass through and the moisture can be adsorbed again. Then, the regeneration air that has passed through the dehumidification rotor 8 is discharged from the regeneration air outlet 22.

  Then, the regenerated portion of the dehumidifying rotor 8 moves again to the dehumidifying flow path 31a side. Therefore, in the dehumidifying unit 6, the dehumidifying rotor 8 is rotationally driven, so that the outside air passing through the dehumidifying passage 31 a is dehumidified while repeating the adsorption and regeneration of moisture by the dehumidifying rotor 8, and is supplied to the indirect vaporizing unit 7. The

  The hot water supplied from the hybrid solar collector 2 to the heater 9 returns to the hybrid solar collector 2 from the heater 9 through the external pipe 14 and is heated again through the finned pipe 4. And supplied to the heater 9.

  In the indirect vaporization air conditioner 3, as described above, the outside air supply fan 28 is driven to generate an air flow from the outside air inlet 20 toward the cooling air outlet 24 and the processing air outlet 2.

  Thereby, a part of the dehumidified outside air that has passed through the dehumidifying channel 31a of the dehumidifying unit 6 passes through the working air channel 10a of the indirect vaporizing element 10 as the working air WA. Further, part of the dehumidified outside air that has passed through the dehumidifying channel 31a passes through the product air channel 10b of the indirect vaporization element 10 as product air PA.

  As described with reference to FIG. 3, in the indirect vaporization element 10, the working air WA passing through the working air flow path 10a is cooled by the heat of vaporization of water, and when the working air WA is cooled, the product passing through the product air flow path 10b. The air PA is cooled by receiving the cold heat of the working air WA.

  And since no movement of humidity occurs between the working air flow path 10a and the product air flow path 10b, the humidity (absolute humidity) of the outside air that has passed through the product air flow path 10b of the indirect vaporization element 10 does not change. The temperature goes down.

  The working air WA that has passed through the working air passage 10a of the indirect vaporization element 10 is discharged from the processing air outlet 23, and the product air PA that has passed through the product air passage 10b is discharged from the cooling air outlet 24.

  During the cooling operation, since the cooling air outlet 24 communicates with the air supply port 25, the low-humidity and low temperature outside air that has passed through the product air flow path 10b of the indirect vaporization element 10 is supplied from the air supply port 25 as the air supply SA. Blown out. Thereby, the indoor temperature can be lowered.

  Further, since the regeneration air outlet 22 and the processing air outlet 23 communicate with the exhaust outlet 26, the high-humidity and high-temperature regeneration air that has passed through the regeneration passage 31b of the dehumidifying unit 6 and the working air flow of the indirect vaporization element 10 The medium-humidity and medium-temperature outside air that has passed through the passage 10a is discharged to the outside as the exhaust EA from the exhaust port 26.

  As described above, the indirect vaporization air conditioner 3 uses the indirect vaporization element 10 of the indirect vaporization unit 7 to reduce the temperature of the outside air OA using the heat of vaporization of water and supply it indoors, thereby suppressing the consumption of electric energy. It can be used as an air conditioner.

  Here, in the indirect vaporization element 10, the outlet temperature of the product air PA decreases as the inlet humidity of the working air WA and the product air PA is lower.

  Therefore, the dehumidification unit 6 is provided in the front stage of the indirect vaporization unit 7, and the outlet temperature of the product air PA can be lowered by dehumidifying the outside air and supplying it to the indirect vaporization unit 7.

  However, if an electric heater is used as a heat source for regenerating the dehumidifying rotor 8 in the dehumidifying unit 6, the electric power consumed by the electric heater is about 1000 watts, so that the electric energy consumption increases.

  Therefore, in the indirect vaporization air conditioner 3, as the heat source for regenerating the dehumidifying rotor 8 of the dehumidifying unit 6, the heater 9 heated by the hot water warmed by the hybrid solar heat collector 2 is used and heated by the heater 9. By using the warm air warmed by the hybrid solar heat collector 2 as well, the regenerative air can suppress the consumption of electric energy and reduce the energy load.

  In particular, since the cooling is often used in a hot state where the sun is in the summer, the hot water and warm air generated by the hybrid solar heat collector 2 have a high temperature and are suitable for the regeneration of the dehumidifying rotor 8. Regenerative air can be efficiently generated using solar energy, and the effect of using the hybrid solar collector 2 is great.

<Example of heating operation of air conditioning system>
FIG. 8 is a configuration diagram showing an air flow during heating in the air conditioning system 1 of the present embodiment. Next, an operation during heating of the air conditioning system 1 will be described.

  First, when performing the heating operation, in the indirect vaporization air conditioner 3, the flow path switching damper 27 a is driven so that the regeneration air outlet 22 and the processing air outlet 23 communicate with the air supply opening 25, and the flow path switching is performed. The damper 27b is driven to make the cooling air outlet 24 communicate with the exhaust outlet 26.

  In the hybrid solar heat collector 2, the regeneration air supply fan 29 is driven, so that the outside air sucked from the outside air introduction opening 16 passes through the air flow path 5 and flows toward the warm air outlet 17. Is generated. Moreover, the water which passes along the piping 4 with a fin circulates by the circulation pump 15 being driven.

  As shown in FIG. 2, when the sunlight S enters the hybrid solar collector 2, the sunlight S irradiates the finned pipe 4. Thereby, the water which flows through the piping 4 with a fin is warmed. Further, the air flowing through the air flow path 5 is also warmed.

  Further, when the water flowing through the finned pipe 4 is warmed, the finned pipe 4 dissipates heat. Here, since the finned pipe 4 is provided with the fins 4a, the heat transfer area is wide. Thereby, heat can be efficiently transmitted to the air flowing through the air flow path 5, and the air flowing through the air flow path 5 is further warmed.

  Thereby, in the hybrid solar collector 2, both hot water and warm air are generated using solar energy.

  In the indirect vaporization air conditioner 3, when the outside air supply fan 28 is driven, an air flow from the outside air inlet 20 toward the cooling air outlet 24 and the processing air outlet 23 is generated.

  In the indirect vaporization air conditioner 3, since the outside air inlet 20 communicates with the dehumidification flow path 31a of the dehumidification unit 6, the outside air OA flows through the dehumidification flow path 31a when the outside air supply fan 28 is driven.

  In addition, the regeneration channel 31 b of the dehumidifying unit 6 communicates with the regeneration air suction port 21. The regenerative air inlet 21 communicates with the warm air outlet 17 of the hybrid solar collector 2 via the regenerative air supply fan 29. As a result, the regeneration air supply fan 29 is driven, and warm air heated by the hybrid solar collector 2 flows as regeneration air in the regeneration flow path 31b.

  In the dehumidifying unit 6, the outside air passing through the dehumidifying channel 31 a is dehumidified by adsorbing moisture to the dehumidifying rotor 8. When the dehumidification rotor 8 is driven to rotate, the portion that has adsorbed moisture moves to the regeneration channel 31b side.

  The heater 9 provided in the regeneration channel 31 b is supplied with hot water heated by the hybrid solar collector 2 by the circulation pump 15 via the external pipe 14. Thereby, the regenerated air passing through the regenerating flow path 31 b is further heated by the heater 9 and passes through the dehumidifying rotor 8. The dehumidification rotor 8 is regenerated to a state where moisture is evaporated by allowing the heated regeneration air to pass through and the moisture can be adsorbed again. Then, the regeneration air that has passed through the dehumidification rotor 8 is discharged from the regeneration air outlet 22.

  Then, the regenerated portion of the dehumidifying rotor 8 moves again to the dehumidifying flow path 31a side. Therefore, in the dehumidifying unit 6, the dehumidifying rotor 8 is rotationally driven, so that the outside air passing through the dehumidifying passage 31 a is dehumidified while repeating the adsorption and regeneration of moisture by the dehumidifying rotor 8, and is supplied to the indirect vaporizing unit 7. The

  The hot water supplied from the hybrid solar collector 2 to the heater 9 returns to the hybrid solar collector 2 from the heater 9 through the external pipe 14 and is heated again through the finned pipe 4. And supplied to the heater 9.

  In the indirect vaporization air conditioner 3, as described above, the outside air supply fan 28 is driven to generate an air flow from the outside air inlet 20 toward the cooling air outlet 24 and the processing air outlet 2.

  Thereby, a part of the dehumidified outside air that has passed through the dehumidifying channel 31a of the dehumidifying unit 6 passes through the working air channel 10a of the indirect vaporizing element 10 as the working air WA. Further, part of the dehumidified outside air that has passed through the dehumidifying channel 31a passes through the product air channel 10b of the indirect vaporization element 10 as product air PA.

  As described with reference to FIG. 3, in the indirect vaporization element 10, the working air WA passing through the working air flow path 10a is cooled by the heat of vaporization of water, and when the working air WA is cooled, the product passing through the product air flow path 10b. The air PA is cooled by receiving the cold heat of the working air WA.

  And since no movement of humidity occurs between the working air flow path 10a and the product air flow path 10b, the humidity (absolute humidity) of the outside air that has passed through the product air flow path 10b of the indirect vaporization element 10 does not change. The temperature goes down.

  The working air WA that has passed through the working air passage 10a of the indirect vaporization element 10 is discharged from the processing air outlet 23, and the product air PA that has passed through the product air passage 10b is discharged from the cooling air outlet 24.

  During the heating operation, since the cooling air outlet 24 communicates with the exhaust port 26, the low-humidity and low-temperature outside air that has passed through the product air flow path 10b of the indirect vaporization element 10 is discharged to the outdoors from the exhaust port 26 as the exhaust EA. Is done.

  Further, since the regeneration air outlet 22 and the processing air outlet 23 communicate with the air supply opening 25, the medium-humidity / high-temperature regeneration air that has passed through the regeneration flow path 31 b of the dehumidifying unit 6 and the working air of the indirect vaporization element 10. The medium-humidity and intermediate-temperature outside air that has passed through the flow channel 10a is mixed and blown out from the air supply port 25 as the air supply SA.

  Since the regeneration air discharged from the regeneration air outlet 22 is heated by the heater 9, it is at a high temperature. However, since the absolute humidity in the outside air is low in winter, the amount of moisture adsorbed to the dehumidification rotor 8 is small in the dehumidification channel 31a of the dehumidification unit 6, and the amount of moisture released from the dehumidification rotor 8 in the regeneration channel 31b is small. The humidity of the regeneration air is not high.

  Accordingly, by mixing the regenerated air with the working air WA having a medium humidity and a medium temperature, warm humidified air can be supplied into the room.

  As described above, in the indirect vaporization air conditioner 3, as the heat source for regenerating the dehumidifying rotor 8 of the dehumidifying unit 6, the heater 9 heated by the hot water heated by the hybrid solar heat collector 2 is used. The regenerative air to be heated also uses the warm air heated by the hybrid solar collector 2 and uses this regenerative air for indoor air supply, thereby reducing the consumption of electric energy and reducing the energy load. Can be used as a reduced heater.

  As described above, the hybrid solar collector 2 of the present example has high heat collection efficiency that combines water and air. Therefore, by using both warm air and hot water generated by the hybrid solar collector 2 Heating can be done efficiently.

  In addition, it is desirable to mount an auxiliary heater in consideration of the case where there is little irradiation of sunlight in winter. Although the auxiliary heater uses an electric heater, the power consumption can be suppressed as compared with the case where all the heaters 9 are realized by an electric heater, so that the energy load can be reduced.

  The present invention is applied to an air conditioning system that performs cooling and heating using warm air and warm water generated by using solar energy.
