摘要： A refrigeration cycle device includes a compressor, a radiator, an air-conditioning heat exchanger, a cooling heat exchanger, an air-conditioning decompression unit, a cooler-unit decompression unit, a refrigerant flow rate detector, and a controller. The radiator is configured to radiate heat of refrigerant discharged from the compressor. The air-conditioning heat exchanger absorbs heat from air to evaporate the refrigerant. The cooling heat exchanger is arranged in parallel with the air-conditioning heat exchanger in the flow of refrigerant. The air-conditioning decompression unit adjusts a decompression amount of the refrigerant flowing into the air-conditioning heat exchanger. The cooler-unit decompression unit adjusts a decompression amount of the refrigerant flowing into the cooling heat exchanger. The controller controls the operation of the cooler-unit decompression unit so that the flow rate of the refrigerant detected by the refrigerant flow rate detector exceeds a predetermined reference flow rate.

摘要： In a heat pump system, when a heat-shock determination portion determines that a difference between a coolant temperature in a coolant flow path and a coolant temperature in a heat source flow path is equal to or higher than a predetermined temperature, a flow-path switching portion mixes the respective coolants flowing through at least a bypass flow path and the heat source flow path together to flow into the coolant flow path.

摘要： A refrigerant cycle device includes a compressor, a radiator, a first expansion valve, a second expansion valve, a first evaporator, a second evaporator, and a controller. The controller is configured to switch between a first evaporator priority control and a second evaporator priority control. During the first evaporator priority control, the controller controls a throttle opening of the second expansion valve based on at least one of a temperature of a first evaporator, a temperature of a refrigerant flowing through the first evaporator, and a temperature of an air having exchanged heat in the first evaporator. During the second evaporator priority mode, the controller controls the throttle opening based on a refrigerant state of the second evaporator. When the at least one of the temperatures is equal to or greater than a switching temperature, the second priority mode is switched to the first priority mode.

摘要： 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.
