Abstract
In a cooling system including a refrigerant compressor for use in a vehicle for refrigerating a refrigerant compartment, the refrigerant compressor is a hermetic type compressor containing a DC electric motor as a compressor driver. An electric generator is actuated by an engine of the vehicle to generate an AC voltage which is, in turn, rectified by a rectifier to produce a DC power for driving the DC electric motor. A switch is provided to switch over from the electric generator to a commercial AC power source so that the commercial AC power is rectified by the rectifier to supply the DC power to thereby enable to drive the compressor by use of the commercial AC power source during a time period when the engine is stopped. In order to cool a passenger compartment of the vehicle, another compressor is provided to be driven by the engine. The other compressor can be temporally used for compressing refrigerant for refrigerating the refrigerant compartment together with the refrigerant compressor by valve control.
