。Next, operate the Danno E 3 J 132 to create the image shown in Figure 4 (
b) and FIG. 5(b), when the bathroom suction port 29 and discharge port 30 are opened, the air conditioning suction port 27 and discharge port 28 are closed. 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.

外に出せない場合好都合である。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.
