PURPOSE:To improve the dehumidifying efficiency of an evaporator and effect dehumidification with small energy loss by a method wherein the low rotations as well as the intermittent operations of outdoor and indoor motors and the opening as well as the closing of a damper are combined in the dehumidification effected by heating cooling air by the introduction of high-temperature atmosphere. CONSTITUTION:In case a room temperature is comparatively high, the damper 11 is closed, the indoor motor 6 is operated intermittently and the amount of ventilation is decreased. In this case, a power is inputted into the contactless relay of an indoor fan so as to lack a part of an electric source waveform of the indoor motor 6 and the indoor motor 6 is driven with the number of rotation lower than the electric source waveform without lacking. In case the room temperature is low, the damper 11 is opened and the high-temperature atmosphere is introduced to the side of the inside of the room. The outdoor motor 9 is operated intermittently just the same as the indoor motor 6. The outdoor motor 9 is operated by the electric source having more lacking portions than the electric source waveform which drives the indoor motor 6 and, therefore, the number of rotation thereof is reduced more. According to this method, the high-temperature atmosphere of outdoor is permitted to be introduced and heating of the indoor cooling air may be effected. |
