PURPOSE:To dispose moisture in indoor air as dew water and prevent frost from adhering to a heat exchanger and clogging it by a constitution wherein exhausting side blades and air supplying side blades are formed integrally so as to pinch a main plate having good heat conductivity. CONSTITUTION:The air supplying side blades 12 and the exhausting side blades 3 are constituted integrally so as to pinch the main plate 4. Cool indoor air in a cold district is discharged to the outside of a room through exhaut air paths A', A''. The indoor air is sent into the heat exchanger 6 by the exhausting side blades 3 driven by a motor 5 and the moisture in the indoor air becomes dew water by contacting with the main plate 4, is cooled by outdoor air by effecting heat exchange, then, is discharged out of a water discharging port 14. The indoor air, whose moisture is removed by the main plate 4 as the dew water, provides the outdoor air with heat energy through the heat transfer plate 7 of the heat exchanger 6, thereafter, is discharged to the outside of the room through the outdoor side discharging port 9 of an outer casing 1. Most of the moisture in the indoor air is removed as the dew water, therefore, the exhaust air path 8a, consisting of the heat transfer plate 7 and spacing plate 8 in the heat exchanger 6, will never cause clogging. |
