To inhibit an endothermic amount of a chiller from being excessive to inhibit deterioration of performance of heating.SOLUTION: A processor 50 controls a flow regulation valve 26 so that at least a part of a refrigerant flowing through a heating element temperature regulation circuit 12 flows to a radiator 24 without going through a chiller 32 when a vehicle internal temperature regulation circuit 14 conducts heating operation, an outdoor temperature is lower than or equivalent to an outdoor temperature threshold value, a temperature of an evaporator 42 is lower than or equivalent to an evaporator temperature threshold value, an exhaust heat rate of a vehicle unit 22 is larger than or equivalent to an exhaust heat rate threshold value, and a temperature of a battery 20 is larger than or equivalent to a battery temperature threshold value.SELECTED DRAWING: Figure 2
【課題】チラーの吸熱量が過多になることを抑制することで、暖房の性能低下を抑制する。【解決手段】プロセッサ50は、車両内温調回路14が暖房動作中であり、外気温が外気温閾値以下であり、エバポレータ42の温度がエバポレータ温度閾値以下であり、車両用ユニット22の排熱量が排熱量閾値以上であり、且つ、電池20の温度が電池温度閾値以上の場合は、発熱体温調回路12を流れる冷媒の少なくとも一部が、チラー32を介さずにラジエータ24へ流れるように流調弁26を制御する。【選択図】図2
