To improve fuel economy of a vehicle while sufficiently cooling a refrigerant for use in both cooling of a battery and air-conditioning of the vehicle.SOLUTION: A refrigerant for cooling a battery 32 circulates in a refrigerant flow passage 12. A compressor 14 is arranged in a refrigerant flow passage 12, and compresses the refrigerant. A condenser 16 is arranged in the refrigerant flow passage 12, and cools the refrigerant by exchanging heat with atmospheric air. A shutter 18 is arranged in a vehicle front direction of an electric automobile, and covers an introduction port of the atmospheric air. When the pressure of the refrigerant in the refrigerant flow passage 12 is not higher than a prescribed pressure during operation of the compressor 14 based on a cooling requirement of the battery 32, an opening/closing control part 506 brings the shutter 18 into a closed state, and when the pressure of the refrigerant exceeds the prescribed pressure, brings the shutter 18 into an open state.SELECTED DRAWING: Figure 1
【課題】バッテリ冷却と車両空調とを兼ねた冷媒の冷却を十分に行いつつ、車両の燃費向上を図る。【解決手段】冷媒流路12は、バッテリ32を冷却する冷媒が循環する。コンプレッサ14は、冷媒流路12上に設けられ冷媒を圧縮する。コンデンサ16は、冷媒流路12上に設けられ、外気との熱交換により冷媒を冷却する。シャッタ18は、電動車の車両前方方向に設けられ、外気の導入口を覆う。開閉制御部506は、バッテリ32の冷却要求に基づくコンプレッサ14の作動中に、冷媒流路12内の冷媒の圧力が所定圧力以下の場合はシャッタ18を閉状態とし、冷媒の圧力が所定圧力を超えた場合はシャッタ18を開状態とする。【選択図】図1
