Abstract

PURPOSE:To dissipate the heat of a semiconductor in an inverter during the operation of a compressor intermediately operated, and to improve the follow-up properties of operation capacity with the increase of load-carrying capacity by working the compressor intermediately operated for a fixed time by using a commercial power source when a compressor is changed over. CONSTITUTION:A controller 16 turns only an electromagnetic switch 13 ON, only No.1 compressor 1a is operated by an output from an inverter 11, and cooling is conducted. When the output is lowered, operation shifts to inverter operation only of No.2 compressor 1b, but the dormant period of the inverter 11 is set when the compressor 1a is changed over to the compressor 1b. The controller 16 turns only an electromagnetic switch 15 ON during the dormant period, and No.2 compressor 1b is worked by a commercial power source AC. Only an electromagnetic switch 14 is turned ON after a fixed time passes, and No.2 compressor 1b is worked by the output from the inverter 11 while the inverter 11 is controlled in response to the output.
