摘要： A refrigeration cycle device includes: a first expansion valve that decompresses a refrigerant flowing out of a high-pressure side heat exchanger; an exterior heat exchanger that exchanges heat between the refrigerant flowing out of the first expansion valve and outside air; a second expansion valve that decompresses the refrigerant flowing out of the exterior heat exchanger; a low-pressure side heat exchanger arranged in series with the exterior heat exchanger; a cooler core that exchanges heat between the heat medium cooled by the low-pressure side heat exchanger and air to be blown into a vehicle interior to cool the air; and a controller configured to switch between a heat absorption mode and a heat dissipation mode by adjusting an amount of decompression in each of the first expansion valve and the second expansion valve.

摘要： A vehicular heat management system includes a heat medium circuit, a heat source portion, and a device. A heat medium cooling an engine circulates in the heat medium circuit. The heat source portion heats the heat medium. The device is configured to function and heat the heat medium when the heat medium flowing into the device is at or above a predetermined temperature. When the engine is being warmed up, heat generated by the heat source portion is supplied to the device in preference to the engine. According to this, since the heat generated by the heat source portion is supplied to the device in preference to the engine when the engine is being warmed up, the engine can be warmed up early.

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.

摘要： A refrigeration cycle device includes a compressor, a condenser, a first decompressor, an outside heat exchanger, and an evaporator. A predetermined part of a refrigerant passage from the condenser to the first decompressor through which the refrigerant flows is a condenser outlet portion. A predetermined part of a refrigerant passage from the first decompressor to the outside heat exchanger through which the refrigerant flows is an outside heat exchanger inlet portion. A predetermined part of a refrigerant passage from the outside heat exchanger to the second decompressor through which the refrigerant flows is an outside heat exchanger outlet portion. A volume capacity of the condenser outlet portion is larger than a volume capacity of the outside heat exchanger inlet portion. According to the refrigeration cycle device, preferable coefficient of performance of cycle can be achieved in different operation modes.

摘要： A vehicular heat management device includes a first heat source, a second heat source, a heater core, a first heat medium pathway, a second heat medium pathway, a heater core pathway, a switching portion, and a control unit. The first heat source is provided in the first heat medium pathway, and the second heat source is provided in the second heat medium pathway. The heater core is provided in the heater core pathway. The switching portion switches between flowing connection and flowing disconnection. The control unit performs at least one of a switching control and a second heat source control when a temperature of the heat medium of the heater core pathway is at or above a predetermined temperature. In the switching control, the switching portion connects the second heat medium pathway to the heater core pathway. In the second heat source control, the second heat source generates heat.
