ABSTRACT:
If an engine is stopped with a switch of an air-conditioner being on, such state is memorized. When the engine is started after dead soak, a compressor is driven automatically until a crank shaft has driven several revolutions to discharge liquid refrigerant from the compressor without liquid-compressing noise. When the engine starts, the compressor is deactivated until the air-conditioner switch is turned on by a driver.
