1. A refrigerant circulation apparatus comprising:

  • a vehicle-interior air conditioner configured to cool an interior of a vehicle;

    an on-vehicle battery cooler including an evaporator for on-vehicle battery cooling configured to cool an on-vehicle battery mounted on the vehicle;

    an electric compressor configured to compress and supply a refrigerant to one or both of the vehicle-interior air conditioner and the on-vehicle battery cooler;

    a temperature detection unit configured to detect a temperature of the electric compressor;

    a pressure detection unit configured to detect a pressure of the refrigerant compressed by the electric compressor; and

    a control unit configured to restrict operation of the evaporator for on-vehicle battery cooling so as to reduce load on the electric compressor based on the temperature of the electric compressor and the pressure of the refrigerant.
