Abstract: A first outward passage and a second outward passage are branched from a branch portion to guide refrigerants to a first evaporator and a second evaporator, respectively. In the second outward passage with a longer refrigerant flow path of the first and second outward passages, a second decompressor is disposed closer to the branch portion rather than the second evaporator in the second outward passage. Further, a part of the second outward passage located on the downstream side of the refrigerant flow with respect to the second decompressor is defined by an inner pipe of a double pipe, and a part of a second return passage is defined by an outer pipe of the double pipe.

Abstract: In an operation mode for heating battery air, a refrigerant passage switching portion switches over to a first refrigerant passage in which a refrigerant including gas refrigerant flowing out of an interior condenser flows into an auxiliary heat exchanger through a first pipe having a relatively large passage cross-sectional area and a liquid refrigerant flowing out of the auxiliary heat exchanger flows to an inlet of an exterior heat exchanger through a second pipe having a relatively small passage cross-sectional area. Meanwhile, in an operation mode for cooling the battery air, the refrigerant passage switching portion switches over to a second refrigerant passage in which a liquid refrigerant flowing out of the exterior heat exchanger flows into the auxiliary heat exchanger through the second pipe and a gas refrigerant flowing out of the auxiliary heat exchanger flows to a suction port of a compressor through the first pipe.

Abstract: A heat pump cycle includes a refrigerant circuit and a coolant circuit. A first heat exchanger and a second heat exchanger are disposed between the refrigerant circuit and the coolant circuit. The first heat exchanger includes an exterior heat exchanger that functions as an evaporator in a heating operation, and a radiator for radiating heat of a coolant. The second heat exchanger transmits a heat of high-pressure refrigerant to the coolant in the heating operation. A temperature of refrigerant within the second heat exchanger is higher than a temperature of refrigerant within the first heat exchanger. The heat obtained from the second heat exchanger is supplied to the first heat exchanger through the coolant. Further, the heat obtained from the second heat exchanger is stored in the coolant. In defrosting operation, the coolant that has stored the heat therein is supplied to the first heat exchanger.

Abstract: When a refrigerant flow-path switch performs switching to a first refrigerant flow path, an interior condenser heating air blown into an interior as a first temperature-adjustment subject and an auxiliary heat exchanger are connected in parallel, and the auxiliary heat exchanger heats air blown to a battery as a second temperature-adjustment subject. In contrast, when the refrigerant flow-path switch performs switching to a second refrigerant flow path, an interior evaporator cooling air blown into the interior and the auxiliary heat exchanger are connected in parallel, and the auxiliary heat exchanger cools the air blown to the battery. With this arrangement, one common auxiliary heat exchanger can cool or heat the air for the battery, thereby leading to reduction in size of an entire refrigeration cycle device.

Abstract: A device temperature regulator is provided with a gas passage part that guides a gaseous working fluid evaporated in a device heat exchanger to a condenser, and a liquid passage part that guides a liquid working fluid condensed in the condenser to the device heat exchanger. The device temperature regulator is provided with a supply amount regulator that increases or decreases a supply amount of the liquid working fluid supplied to the device heat exchanger. The supply amount regulator decreases the supply amount of the liquid working fluid to the device heat exchanger such that a liquid surface is formed in a state where the gaseous working fluid is positioned at a lower side lower than a heat exchanging portion exchanging heat with a temperature regulation target device in the device heat exchanger, when a condition for keeping the temperature regulation target device at a temperature is satisfied.

Abstract: A refrigeration cycle device includes an air heat exchanger that heats air to be blown into an interior of a vehicle compartment using refrigerant discharged from a compressor, a high-stage side expansion valve decompressing the refrigerant flowing out of the air heat exchanger, and a battery heat exchanger that heats air to be blown to a battery using the refrigerant decompressed by the high-stage side expansion valve. In an air heating-warming up mode of heating the air for the interior and the air for the battery, a refrigerant discharge capacity of the compressor is controlled such that an air temperature for the interior approaches a target air temperature, and an opening degree of the high-stage side expansion valve is controlled such that a battery temperature becomes within a predetermined reference temperature range. A selector switch allows a passenger to select which operation of air conditioning or warming-up is prioritized.

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.
