PURPOSE:To obtain the most proper cooling and dehumidifying capacities in accordance with a condition by a method wherein the ON, OFF control of the operation of a compressor is effected by comparing a room temperature with a set room temperature while the capacity of the compressor is varied in accordance with the temperature of an evaporator or a humidity in a room. CONSTITUTION:The room temperature is detected by a room temperature sensor 11, the humidity in the room is detected by an indoor humidity sensor 13 and, further, the temperature of the evaporator is detected by a heat exchanging temperature sensor 5. When the room temperature is higher than the set room temperature, a switch 12 is put ON and a compressor motor 1M is operated. That means the operation of the compressor 1 is started. Thereafter, when a refrigerating cycle has almost been stabilized, a mian control unit 10 compares the detected temperature of the evaporator with a latent heat ratio corresponding to a desired humidity, decides the setting of the revolving number of the compressor motor 1M by said comparation and outputs a revolving number setting command A. Thus, the revolving number of the compressor motor 1M is changed and the capacity of the compressor 1 is set into a condition wherein the sufficient dehumidifying capacity may be obtained. |
