Zusammenfassung: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 【課題】バッテリの消耗を招くことなく、エアコンの圧縮機(コンプレッサ)の液圧縮音を抑制できるようにする。【解決手段】前回エアコン1が作動されていないときに、エンジン10の始動後、エンジン回転数が所定回転数以上低下した場合に、エンジンECU14により、マグネットクラッチ17が予め設定された断続タイミングで所定回数断続されたのち接続状態に保持されて、圧縮機2が断続されたのち連続的に駆動される。これにより、圧縮機2に冷媒の液体が溜まった状態で圧縮機2を駆動するときに、はじめに圧縮機2を断続することで、圧縮機2内の液体を排出してから圧縮機2を連続駆動でき、圧縮機2に溜まった冷媒の液体に起因する激しい液圧縮音を未然に防止することができる。【選択図】図1
