Adsorption heat exchangers (51, 52) that perform adsorption action and regeneration action are switched in alternating fashion. A low-pressure-side motorized valve (56) is connected to a low-pressure-side pipe (13) of a humidity control unit (50), and the opening degree of the low-pressure-side motorized valve (56) is adjusted on the basis of the evaporation temperature of the adsorption heat exchangers (51, 52) serving as evaporators. |
