An outside air temperature thermistor 22 for detecting the outside air temperature is disposed in the outdoor unit. The outside air temperature and the compressor shell temperature are compared, and the compressor heating device is made disabled when the shell temperature is higher than the outside air temperature. A refrigerant accumulating condition is determined, and the compressor heating device is operated, when the shell temperature is lower than the outside air temperature. In the case where the shell temperature is higher than the outside air temperature by a certain specific temperature or more, the operation of the compressor heating device is stopped, thus the wasteful standby power is reduced, and energy-saving of the device is achieved.
