  Here, the refrigeration cycle of the air conditioner of the present invention will be described. FIG. 13 is a diagram showing a refrigeration cycle of an air conditioner conditioner. The refrigeration cycle is roughly composed of an outdoor unit 1 and an indoor unit 2. The refrigerant discharged from the compressor 36 in the outdoor unit passes through the four-way valve 26, passes through the tank 28 during cooling operation, passes through the outdoor heat exchanger 8, passes through the other tank 33, and passes through the expansion valve 31. It passes through the indoor heat exchanger 37 and returns to the compressor 36 through the four-way valve 26.

  In such a refrigeration cycle, in the air conditioner, when the refrigerant passes through the two tanks 28 and 33, the refrigerant is cooled by the tap water in the tanks 28 and 33. As the refrigerant is cooled in this manner, the cooling efficiency is increased and power is saved. On the contrary, the temperature of the tap water in the tanks 28 and 33 rises and is sent to the bathtub 39, thereby reducing the utility cost for reheating the bath and reducing the heat load on the atmosphere.

  FIG. 14 is a diagram illustrating a heating cycle of the air conditioner conditioner. During the heating operation, the cycle opposite to the above-described refrigeration cycle is advanced by the operation of the four-way valve 26. The refrigerant discharged from the compressor 36 in the outdoor unit passes through the four-way valve 26, through the indoor heat exchanger 37, through the expansion valve 31, through the tank 33, through the outdoor heat exchanger 8, and another one. It passes through the tank 28 and returns to the compressor 36 through the four-way valve 26. When the refrigerant passes through the two tanks 28 and 33, the refrigerant is warmed by the remaining hot water in the tanks 28 and 33, so that the heating efficiency is improved and power is saved, and the fins of the outdoor heat exchanger 8 are Also effective for defrosting.

  FIG. 15 is a cross-sectional view showing a cooling operation state of the outdoor unit of the air conditioner conditioner. As shown in FIG. 15, in the cooling operation of the outdoor unit 1 and the heat exchanger chamber 6 configured as described above, the fan motor 9 of the outdoor unit 1 is activated and the fan 10 rotates, so that the outside air moves in the direction of the arrow. move on. The outside air is sucked into the outdoor unit and heated by passing through the heat exchanger 8, is heated as hot air, is discharged from the blowout port 5, is blown to the heat exchanger coil 13, and the heat exchanger coil 13 captures the hot air. .

  FIG. 16: is a perspective view which shows the use condition which warms tap water and sends water to a bathtub in an outdoor unit. In the heat exchanger coil 13, as shown in FIG. 16, when the water supply valve 40 is opened, tap water having a temperature lower than the outside air temperature passes through the pipe 41 and passes through the tap water inlet 19 of the heat exchanger coil 13 to the heat transfer pipe 18. Water is sent to Then, the tap water cools the copper heat transfer tubes 18 and the aluminum fins 17. By contacting the heat transfer tubes 18 and the fins 17 thus cooled, the hot air discharged from the outlet 5 is cooled and released into the atmosphere, so that the heat load on the atmosphere is reduced.

  On the contrary, the tap water inside the heat transfer tube 18 of the heat exchanger coil 13 provided on the front surface of the outlet 5 is warmed by the hot air. The warm tap water is supplied to the bathtub 39 until the overblow prevention device 43, which is a device that automatically stops at a predetermined water level, is activated so that the tap water does not overflow through the pipe. By supplying the tap water warmed in this way to the bathtub 39, it is possible to reduce the utility cost of reheating the bath and the heat load released to the atmosphere.

  Further, when the outdoor unit is not used and the outside air temperature is higher than the tap water temperature, the cross flow fans 15 and 16 are operated with the generated power of the solar cell panel 12 or the common AC power source as shown in FIG. Warm outside air is blown to the heater coil 13 in the direction of the arrow to warm the tap water inside the heat transfer tube 18. By supplying the tap water whose water temperature has risen from the water outlet 20 to the bathtub 39 through the pipe 42, it is possible to reduce the utility cost of reheating the bath and reduce the heat load on the atmosphere.

  Moreover, the solar cell panel 12 closely attached to the solar cell unit 11 is cooled by supplying tap water from the water inlet 22 of the solar cell unit 11 shown in FIG. Further, in order to cool the refrigerant pipe 27 in the outdoor unit 1 shown in FIG. 10 and the refrigerant pipe 32 shown in FIG. 11, tap water is supplied to the water inlet 29 of the tank 28 in the outdoor unit 1 as shown in FIG. Water is supplied, water is supplied from the water outlet 30 through the pipe connection 44 to the water outlet 35 of the other tank 33, and water is supplied from the water inlet 34 to the bathtub 39. In this way, cooling of tap water suppresses a temperature rise on the surface of the solar cell panel 12 to suppress a decrease in power generation efficiency, and cooling of the refrigerant improves cooling efficiency to save power.

  Conversely, the tap water in the solar cell unit 11 is warmed, but the warm tap water is further heated in the tank 28 and the tank 33 by the refrigerant in the refrigerant pipe. By supplying the heated water to the bathtub 39 in this way, it is possible to reduce the utility cost of reheating the bath and reduce the heat load on the atmosphere.

FIG. 19 is a perspective view showing a usage state of remaining hot water in the outdoor unit. In winter, when there is snow, the remaining hot water in the bath is sent to the water inlet 22 of the solar cell unit 11 by the pumping pump 38, so that the snow on the surface of the solar cell panel 12 is heated by the remaining hot water in the bath. Can be melted. Further, as shown in FIG. 14, the remaining hot water of the bath is passed from the water inlet 34 of the tank 33 through the water outlet 35 , through the pipe connection 44, and from the water outlet 30 of the other tank 28 through the water inlet 29. The remaining hot water in the bath can heat the refrigerant in the refrigerant pipes penetrating the tanks 28 and 33. In this way, heating efficiency is increased and power is saved, and outdoor heat exchange is performed from the refrigerant pipes. Heat transfer to the fins of the oven is also effective for defrosting the fins of the outdoor heat exchanger.
