During a simple ventilation operation, in an outdoor-air conditioner (10) which is a humidity control apparatus, a first bypass damper (83) is opened to supply outdoor air to a room in unchanged form. When the outdoor temperature exceeds 35° C. during the simple ventilation operation, an operation of the outdoor-air conditioner (10) is forcibly switched to a dehumidification/ventilation operation, and then outdoor air passing through an adsorption heat exchanger (51, 52) operating as an evaporator is supplied to the room. When the outdoor temperature falls below 5° C. during the simple ventilation operation, the operation of the outdoor-air conditioner (10) is forcibly switched to a humidification/ventilation operation, and then outdoor air passing through the adsorption heat exchanger (51, 52) operating as a condenser is supplied to the room. That is, when the operation of the outdoor-air conditioner (10) is switched from the simple ventilation operation to the dehumidification/ventilation operation or the humidification/ventilation operation, a difference between the temperature of air to be supplied to the room and the room temperature is reduced as compared to that during the simple ventilation operation. |
