To assure both of air cooling capacity and battery cooling capacity as much as possible.SOLUTION: A control part 50 can be switched between second evaporator priority control that controls a throttle opening of a second expansion valve 15 on the basis of a coolant state of a second evaporator 16, and first evaporator priority control that controls a throttle opening of the second expansion valve 15 on the basis of at least one temperature among a temperature of a first evaporator 14, a temperature of a coolant flowing in the first evaporator 14, and a temperature of air heat-exchanged in the first evaporator 14. When at least one temperature among the temperature of the first evaporator 14, the temperature of the coolant flowing in the first evaporator 14 and the temperature of air heat-exchanged in the first evaporator 14 becomes a switching temperature or higher in second evaporator priority control, the second evaporator priority control is switched to the first evaporator priority control.SELECTED DRAWING: Figure 4
【課題】空気冷却能力および電池冷却能力の両方を極力確保することを目的とする。【解決手段】制御部50は、第2蒸発器16の冷媒状態に基づいて第2膨張弁15の絞り開度を制御する第2蒸発器優先制御と、第1蒸発器14の温度、第1蒸発器14を流れる冷媒の温度、および第1蒸発器14で熱交換された空気の温度のうち少なくとも1つの温度に基づいて第2膨張弁15の絞り開度を制御する第1蒸発器優先制御とを切り替え可能になっており、第2蒸発器優先制御において、第1蒸発器14の温度、第1蒸発器14を流れる冷媒の温度、および第1蒸発器14で熱交換された空気の温度のうち少なくとも1つの温度が切替温度以上になると、第1蒸発器優先制御に切り替える。【選択図】図4
