<p>First and second adsorption heat exchangers (51, 52) where adsorption agent is carried are used as heat exchangers of a refrigeration circuit (50), and switching over of an evaporator and a condenser is made possible. An air channel (60) is constructed so that it can be switched over regardless of through which one of the first and second adsorption heat exchangers (51, 52) air from outdoor to indoor and air from indoor to outdoor flows. Further, the following operation modes are made possible: a dehumidifying mode and a humidifying mode where the flow of refrigerant and the flow of air are switched over for each predetermined time period, a cooling operation mode and a heating mode where the flow of refrigerant and the flow of air are not switched over, and a ventilation operation mode where air is conducted through the air channel (60) with the refrigerant circuit (50) closed.</p> |
