When an outdoor-air conditioner (10), which is a humidity control device, is engaged in a simple ventilation operation, a first bypass damper (83) is opened and outdoor air is supplied as it is to indoors. When the outdoor temperature becomes above 35˚C in the simple ventilation operation, operation of the outdoor-air conditioner (10) is forcibly switched to dehumidification/ventilation operation, and this causes outdoor air having passed through an adsorption heat exchanger (51, 52) functioning as an evaporator to be supplied indoors. Also, when the outdoor temperature becomes below 5˚C in the simple ventilation operation, operation of the outdoor-air conditioner (10) is forcibly switched to humidification/ventilation operation, and this causes outdoor air having passed through an adsorption heat exchanger (51, 52) functioning as a condenser to be supplied indoors. That is, when operation of the outdoor-air conditioner (10) is switched from the simple ventilation operation to the dehumidification/ventilation operation or the humidification/ventilation operation, the difference between the temperature of air supplied indoors and the temperature indoors is less than that in the simple ventilation operation. |
