Therefore, the refrigerant hardly flows to the outdoor heat exchanger 13, and after radiating heat through the reheating heat exchanger 16 during dehumidification, it passes through the air conditioning heat exchanger 15 and returns to the compressor 12 from the four-way valve 17.

In this manner, the air conditioning heat exchanger 15 acts as a refrigerant evaporator to cool and dehumidify the surrounding air during cooling and dehumidification, and acts as a radiator to warm the surrounding air during heating. Also, during dehumidification, the reheating heat exchanger 16
operates to warm the surrounding air.

The air conditioner 1 also includes an outdoor heat exchanger blower 20 and an air conditioning blower 21 in its housing 11 . Note that the shower heat exchanger 14 is installed in the shower heating tank 22 in FIG. 2(a).

When the air conditioner is operated in this state, air in the bathroom is drawn into the air conditioning heat exchange chamber 25, heat exchanged, and then discharged into the bathroom. Therefore, when the bathroom suction port 29 and the discharge port 30 are opened, the solenoid valve 18 of the refrigerant circuit is opened and the air conditioner is operated to dehumidify the air in the bathroom 2. The air in the bathroom 2 is dried. That is, the air in the bathroom enters the air conditioning heat exchange chamber 25, where it is cooled and dehumidified by the air conditioning heat exchanger 15, as shown in FIG. The dehumidified air is heated by the reheating heat exchanger 16 during dehumidification and becomes warm air with low humidity. This warm air is discharged into the bathroom 2 from the bathroom outlet 30. Therefore, the bathroom can be used as a drying room.

In general, a bathroom is a space that is not used except for bathing, and the temperature is relatively high during bathing, and it is also used as a laundry area or a place where a laundry area can be set up nearby, so the bathroom is a drying room. Being able to do this is convenient if you cannot take your laundry outside.
