PURPOSE:To prevent drying by providing an air-permeable water absorber in a position where the dew formed through heat exchange is stored so as to impart appropriate moisture to the room air. CONSTITUTION:On the heat exchange in a heat exchanger 18, the moisture contained in the warm room air is cooled by the cold outside air to be condensed into dew, and the dew dropping out of the heat exchanger 18 is received by and stored in a water absorber 26. Because the water absorber 26 is air-permeable and the room air from the room air suction port is sucked through the water absorber 26, the sucked room air gets wet while passing through the water absorber 26, before mixed with the outside air and discharged into the room. |
