Abstract: A composite heat exchanger is used in a vapor compression refrigeration cycle. The vapor compression refrigeration cycle includes: a compressor; a decompressor configured to decompress a high-pressure refrigerant discharged from the compressor; and an evaporator configured to evaporate a low-pressure refrigerant decompressed at the decompressor by exchanging heat between the low-pressure refrigerant and a first heat medium. The composite heat exchanger includes a condenser unit, a liquid storage unit temporarily storing a high-pressure liquid refrigerant, a sub-cooler unit sub-cooling the high-pressure liquid refrigerant through heat exchange with a second heat medium, and an internal heat exchanger unit exchanging heat between the high-pressure liquid refrigerant passed through the sub-cooler unit and the low-pressure refrigerant. The condenser unit, the sub-cooler unit and the internal heat exchanger unit are joined together by a predetermined binding element and thereby form an integral structure.

Abstract: A battery temperature control device includes a heating medium circuit that connects a battery heat exchanger, an outside air heat exchanger, a heating medium pump, and a flow rate regulating unit. The outside air heat exchanger is connected in parallel to the battery heat exchanger. The flow rate regulating unit adjusts a flow rate of the heating medium in a first path through which the heating medium flows via at least the outside air heat exchanger and a flow rate of the heating medium in a second path through which the heating medium flows by detouring around the outside air heat exchanger. The control unit controls the flow rate regulating unit to adjust a ratio between a flow rate of the heating medium in the first path and a flow rate of the heating medium in the second path.

Abstract: A refrigeration cycle device includes a compressor, a radiator, a first decompression unit, a first evaporator, a second decompression unit, and a second evaporator. A refrigerant joining portion joins refrigerant having passed through the first evaporator and the second evaporator, on a refrigerant suction side of the compressor. The first decompression unit regulates a degree of superheating of the refrigerant between the first evaporator and the refrigerant joining portion on the basis of a first physical quantity having a correlation with the degree of superheating of the refrigerant flowing between the first evaporator and the refrigerant joining portion. The second decompression unit regulates a degree of superheating of the refrigerant between the refrigerant joining portion and the compressor on the basis of a second physical quantity having a correlation with the degree of superheating of the refrigerant flowing between the refrigerant joining portion and the compressor.

Abstract: A vehicular air conditioner includes a refrigeration cycle system, a high-temperature heat medium circuit, and a low-temperature heat medium circuit. The high-temperature heat medium circuit includes an air-heat medium heat exchanger, a heater core, a branching portion, a common passage, a flow rate adjuster, and an auxiliary heat source. The air-heat medium heat exchanger exchanges heat between the heat medium and an outside air. The heater core is arranged parallel to the air-heat medium heat exchanger and causes the heat medium to transfer heat to a ventilation air. The branching portion divides a flow of the heat medium into a flow toward the air-heat medium heat exchanger and a flow toward the heater core. The auxiliary heat source is arranged in the common passage at a position upstream of the branching portion.

Abstract: A housing forms: a first space and a second space; and a third space that is placed on one side relative to the first space and the second space in one direction. A primary partition partitions between the first space and the second space, and secondary partitions partition the first space into a plurality of subspaces. A valve element has: a first communication passage extending through the valve element in the one direction; and a second communication passage recessed on the valve element from another side toward the one side in the one direction. In response to movement of the valve element, the valve element changes a subspace to be communicated with the third space through the first communication passage among the plurality of subspaces and also changes another subspace to be communicated with the second space through the second communication passage among the plurality of subspaces.

Abstract: A refrigeration cycle device includes a compressor configured to compress and discharge a refrigerant containing oil, a refrigerant radiator configured to heat the ventilation air using the refrigerant discharged from the compressor as a heat source during a room interior heating, a refrigerant decompression unit configured to decompress the refrigerant having passed through the refrigerant radiator, an evaporator configured to evaporate the refrigerant and to function as a heat absorber during the room interior heating; and a controller configured to control the refrigerant decompression unit and to perform a fluctuation operation at least during the room interior heating. In the fluctuation operation, a throttle opening degree of the refrigerant decompression unit is changed such that a refrigerant state on a refrigerant outlet side of the evaporator is alternately changed to a superheated state having a superheat degree and a wet state containing the wet vapor.

Abstract: In a refrigeration cycle device, in an operation mode in which a refrigerant does not flows into a cooling evaporator, a throttle opening degree characteristic of a heat absorption valve disposed upstream of a heat absorption evaporator is set to cause the refrigerant on the outlet side of the heat absorption evaporator to be in a gas-liquid two-phase state.

Abstract: An air conditioning device for a vehicle includes a door control unit that controls multiple blowing port doors or an air mix door to prevent a heat generated from a heater core from leaking out of an air conditioning case before air conditioning of a vehicle interior is determined to be started. The air conditioning device includes an air conditioning control unit that performs the air conditioning of the vehicle interior by controlling the multiple blowing port doors to open at least one of multiple blowing ports and blow out a heat in the air conditioning case as hot air to the vehicle interior from the at least one blowing port after the air conditioning in the vehicle interior is determined to be started.

Abstract: An air conditioner for a vehicle includes a refrigeration cycle, a heating unit and a control unit. The refrigeration cycle includes an air-conditioning evaporator, a chilling evaporator, an air-conditioning side flow path, a detour flow path and an air-conditioning flow rate adjustment unit. The control unit includes a determination unit that determines whether a condensation condition is satisfied when a refrigerant is flowing through the chilling evaporator via the detour flow path in a state where an inflow of a refrigerant into the air-conditioning evaporator is prohibited. When the determination unit determines that the condensation condition is satisfied, the control unit controls the air-conditioning flow rate adjustment unit to allow an inflow of a refrigerant into the air-conditioning evaporator as a condensation suppression operation for suppressing condensation of a refrigerant in the air-conditioning evaporator.
