PROBLEM TO BE SOLVED: To make it possible to suppress a liquid compression sound of a compressor of an air conditioner without causing consumption of a battery.SOLUTION: When an engine speed is lowered by a prescribed revolution speed or more after an engine 10 is started in the state that an air conditioner 1 is not operated at a previous time, a magnet clutch 17 is disconnected by an engine ECU 14 at a preset disconnection timing, and thereafter, is held in a connection state, the compressor 2 is continuously driven after disconnection. Thus, when the compressor 2 is driven in the state that a coolant liquid is accumulated in the compressor 2, the compressor 2 is firstly disconnected, and consequently, the compressor 2 can be continuously driven after discharging the liquid in the compressor 2, whereby a severe liquid compression sound due to the coolant liquid accumulated in the compressor 2 can be prevented before generation.SELECTED DRAWING: Figure 1 |
