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 method for manufacturing a device temperature controller includes filling an inside of a circuit with working fluid by connecting a filling port of the circuit to a container that stores gas phase working fluid. The circuit constitutes a thermosiphon heat pipe and allows the working fluid to circulate in the circuit. In the filling, the working fluid inside the circuit is cooled by a cooling source. An inside temperature of the circuit is decreased to be lower than an inside temperature of the container, and thereby an inside pressure of the circuit is decreased to be lower than an inside pressure of the container.

Abstract: A vehicle air conditioning apparatus includes: at least one processor programmed to control a flow rate of at least one of a heat medium and outside air flowing through a heat medium-to-outside air heat exchanger such that a temperature of blast air cooled in an air-cooling heat exchanger is adjusted toward a first target temperature, and to control a flow rate of a refrigerant discharged from a compressor such that a temperature of blast air, which has been adjusted in at least one of the air-cooling heat exchanger and an air-heating heat exchanger and which is blown out into a vehicle interior, is adjusted toward a second target temperature. Accordingly, a surface temperature of the air-cooling heat exchanger and the temperature of the blast air into the vehicle interior can be properly controlled.

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.
