Title:
REFRIGERATION CYCLE APPARATUS FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2016/117309
Kind Code:
A1
Abstract:
This refrigeration cycle apparatus for a vehicle has: a compressor (26) for suctioning and discharging a refrigerant, heat dissipating heat-exchangers (14, 23) for dissipating heat from the refrigerant discharged from the compressor, and a depressurizing device (28) for depressurizing the refrigerant from which heat has been dissipated by the heat dissipating heat-exchangers. The refrigeration cycle apparatus for a vehicle is provided with heat absorbing heat-exchangers (13, 22) for absorbing heat from the refrigerant depressurized by the depressurizing device, a heat medium circuit (10) through which a heat medium circulates, and a control device (40) for controlling the operation of the compressor. At least one of the heat dissipating heat-exchangers and the heat absorbing heat-exchangers is configured to exchange heat between the refrigerant and the heat medium, and when the temperature variation of the heat medium satisfies a predetermined predicted condition, the control device performs a capacity lowering control for temporarily lowering the refrigerant discharging capacity of the compressor. Accordingly, when the temperature of the heat medium varies thereby causing the refrigerant pressure of the refrigeration cycle to vary, the refrigerant discharging capacity of the compressor can be temporarily lowered so that the torque of the compressor can be prevented from varying.
