Abstract:

A humidity control device (10) performs humidification operation in which outdoor air is supplied into a room through a moisture desorption/adsorption heat exchanger which acts as a condenser, and indoor air is discharged outdoors through a moisture absorption/adsorption heat exchanger which acts as an evaporator. This humidity control device (10) is provided with: a pre-heating heat exchanger (34) for functioning as a condenser in a refrigerant circuit (15) and heating outdoor air, the pre-heating heat exchanger being positioned upstream from the moisture desorption/adsorption heat exchanger in the flow of outdoor air in an air passage during humidification operation; and a heat recovery heat exchanger (35) for functioning as an evaporator in the refrigerant circuit (15) and recovering the heat of indoor air, the heat recovery heat exchanger being positioned downstream from the moisture absorption/adsorption heat exchanger in the flow of indoor air in the air passage during humidification operation.
