PROBLEM TO BE SOLVED: To provide a vehicle refrigeration cycle device for suppressing a torque variation of a compressor even when a heat medium temperature of a heat medium circuit varies.SOLUTION: A vehicle refrigeration cycle device comprises: a compressor 26 which draws in and delivers refrigerant; a heat-radiation heat exchanger 14 which radiates heat of the refrigerant delivered from the compressor; decompression means 28 which decompresses the refrigerant heat-radiated by the heat-radiation heat exchanger; a heat-absorption heat exchanger 13 which absorbs the heat of the refrigerant decompressed by the decompression means; a heat medium circuit 10 which circulates a heat medium therein; pumps 11, 12 which draw in and deliver the heat medium; and a control unit which controls the compressor to operate, at least either the heat-radiation heat exchanger or the heat-absorption heat exchanger implementing heat exchange between the refrigerant and the heat medium, and the control unit exerting a capability reduction control to temporarily reduce a refrigerant delivery capability of the compressor when a predetermined condition on which a temperature variation of the heat medium is predicted is satisfied.SELECTED DRAWING: Figure 1

    【課題】熱媒体回路の熱媒体温度が変動しても、圧縮機のトルク変動を抑制する車両用冷凍サイクル装置を提供する。【解決手段】冷媒を吸入して吐出する圧縮機26と、圧縮機から吐出された冷媒を放熱させる放熱用熱交換器14と、放熱用熱交換器で放熱された冷媒を減圧させる減圧手段28と、減圧手段で減圧された冷媒を吸熱させる吸熱用熱交換器13と、熱媒体が循環する熱媒体回路10と、熱媒体を吸入して吐出するポンプ11,12と、圧縮機の作動を制御する制御装置とを備え、放熱用熱交換器および吸熱用熱交換器のうち少なくとも一方は、冷媒と熱媒体とを熱交換させるようになっており、制御装置は、熱媒体の温度変動が予想される所定条件を満たした場合、圧縮機の冷媒吐出能力を一時的に低下させる能力低下制御を行う。【選択図】図1
