Abstract: A humidity control apparatus has a refrigerant circuit 20 that has a compressor 21 and a first adsorption heat exchanger 23 and a second adsorption heat exchanger 25, each of which has an adsorbent for adsorbing the moisture of air supported thereon, and that reversibly circulates refrigerant to perform a vapor compression refrigeration cycle. The refrigerant circuit 20 is provided with a sensible heat exchanger 26 in which the refrigerant after having passed through the adsorption heat exchanger 23, 25 functioning as an evaporator exchanges heat with the air having passed through the adsorption heat exchanger 23, 25 functioning as a condenser, thereby cooling the air.

Abstract: A casing includes a holding member for holding an adsorption member for adsorbing moisture, and a heating medium circuit for heating or cooling an adsorbent of the adsorption member. The holding member is configured to be drawn out of the casing, while holding the adsorption member and the heating medium circuit together.

Abstract: The invention is directed to downsize a humidity adjustment unit as much as possible, thereby reducing the whole size of an air conditioner. An air conditioner (1) includes a humidity adjustment unit (2) for adjusting air humidity, and a temperature adjustment unit (8) for adjusting air temperature. The humidity adjustment unit (2) includes a humidity adjustment casing (20), first and second adsorption heat exchangers (14, 15) for adjusting the humidity of the air in the humidity adjustment casing (20), and a humidity adjustment electrical component unit (19). The temperature adjustment unit (8) includes a temperature adjustment casing (80) aligned with the humidity adjustment casing (20), and a temperature adjustment heat exchanger (94) which is contained in the temperature adjustment casing (80), and adjusts the temperature of the air.
