Abstract

PURPOSE:The unnecessitate a water exhaust pipe for draining and make it possible to humidify the room at the heating time by discharging the drain dewed in an indoor heat exchanger, at the cooling time, and introducing the drain dewed in the outdoor heat exchanger to the indoor side to humidify the same. CONSTITUTION:At the heating time, a damper 19 is located at a position indicated by solid line by means of a damper motor 18, and drain dewed in an outer heat exchanger 11 which is used as an evaporator falls onto a drain pan 13, and is stored in a storage tank 14. When the drain increases, a carrent is caused to flow through a heater 16 by a switch 17, and the drain is heated and evaporated. The drain is induced by to an indoor fan 21 and mixed with dry air from the indoor heat exchanger 10, and converted into humid air and blows out through a blow-off port 7. At the cooling time, the damper 19 is changed over to a dot-line position, the drain dewed in the indoor heat exchanger 10 falls onto the drain pan 12, and turned into vapor similarly and blown off to the outside of the chamber through the outdoor blow-off port 9.
