Abstract: A refrigeration cycle device for a vehicle has a compressor, a first pump, a high-pressure side heat exchanger, a heating medium-outside air heat exchanger, and a controller. The compressor draws and discharges a refrigerant. The first pump draws and discharges a first heating medium. The high-pressure side heat exchanger heats the first heating medium by exchanging heat between a high-pressure refrigerant discharged from the compressor and the first heating medium. The heating medium-outside air heat exchanger exchanges heat between the first heating medium and outside air. The controller controls operation of the compressor and the first pump. The controller activates the first pump when an activation request of the compressor is made. The controller activates the compressor, after activating the first pump, when it is determined or estimated that a temperature of the first heating medium is lower than or equal to a first predetermined value.

Abstract: A vehicular heat management system has a compressor, a heat-medium heating heat exchanger, and a flow adjustment part. The compressor draws and discharges a refrigerant. The heat-medium heating heat exchanger causes a heat exchange between the refrigerant discharged from the compressor and a heat medium other than air and heats the heat medium. The flow adjustment part causes a flow of a cooling fluid cooling the refrigerant when the compressor is stopped. The vehicular heat management system further has a refrigeration cycle unit and a refrigerant-flow-path forming member. The refrigeration cycle unit includes devices configuring a refrigeration cycle. The refrigerant-flow-path forming member (i) is disposed in a low-temperature area having an air temperature that is lower than an air temperature in an area in which the refrigeration cycle unit is disposed, and (ii) passes a refrigerant in the refrigeration cycle flows.

Abstract: A refrigeration cycle device has a compressor, a radiator, a decompressor, an evaporator, a heat medium cooling evaporator, a cooling target device, a detector, and a controller. The heat medium cooling evaporator cools a cooling heat medium by performing a heat exchange between the refrigerant decompressed in the decompressor and the cooling heat medium. The cooling heat medium cools the cooling target device. The detector detects a subcooling state of the cooling target device having a temperature lower than or equal to a reference temperature. Upon the detection of the subcooling state in the cooling target device by the detector, the controller increases the degree of superheat of the refrigerant flowing out of the heat medium cooling heat exchanger as compared to the degree of superheat of the refrigerant flowing out of the heat medium cooling heat exchanger when the detector does not detect the subcooling state.
