A humidity conditioning device, comprising an adsorbing element and a refrigerant circuit, wherein, to prevent a performance from lowering due to frost formation on evaporators at the time of humidification, for example, an operation to raise the evaporation temperature of the refrigerant circuit (100) is performed for defrosting when frost formation occurs on the evaporators (103, 104) by primary air passing the evaporators (103, 104) in the refrigerant circuit (100). |
