PROBLEM TO BE SOLVED: To effectively prevent accumulation of liquid refrigerant inside of a compressor with a simple constitution, so as to improve reliability of an apparatus and to reduce power consumption. SOLUTION: The compressor is provided with plural electric heaters and a compressor temperature detecting device for detecting a temperature of an outer hull of the compressor, a control device is disposed to change the number of electric heaters to which power is distributed on the basis of a value of the compressor outer hull temperature in stopping the compressor, and the number of electric heaters to which power is distributed is increased when the compressor outer hull temperature is low during the stop of the compressor. In particular, the increase of cost is prevented by using the electric heater of standard specification, when a heat capacity is high. COPYRIGHT: (C)2008,JPO&INPIT |
