Patent attributes
A humidity control apparatus includes two adsorbing elements (81, 82), and performs a batch-type operation. The humidity control apparatus includes a refrigerant circuit (100). A second air for regenerating the adsorbing element (81, 82) is heated through a regenerative heat exchanger (102) of the refrigerant circuit (100). The refrigerant circuit (100) includes a first heat exchanger (103) and a second heat exchanger (104). In a dehumidification mode, the first heat exchanger (103) serves as an evaporator, and the first air to be supplied exchanges heat with the refrigerant. At this point, the second heat exchanger (104) is inactive. In a dehumidification mode, the second heat exchanger (104) serves as an evaporator, and the first air to be discharged exchanges heat with the refrigerant. At this point, the first heat exchanger (103) is inactive.
