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 combined heat exchanger exchanges heat between a refrigerant circulating through a vapor compression type refrigeration cycle, a first heat medium flowing through a first heat medium circuit including a first heat generating element, and a second heat medium flowing through a second heat medium circuit including a second heat generating element. The combined heat exchanger includes a refrigerant flow channel portion through which the refrigerant flows, a first heat medium flow channel portion through which the first heat medium flows, and a second heat medium flow channel portion through which the second heat medium flows. The refrigerant flow channel portion, the first heat medium flow channel portion, and the second heat medium flow channel portion are arranged to transfer heat of the refrigerant to both the first heat medium and the second heat medium.

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: In an air conditioner, a heat medium circuit includes: a first branch part, a first merging part, a second branch part, and a second merging part. A first flow rate adjusting unit is disposed in the heat medium circuit between the first branch part and an outside-air heat exchanger or between the outside-air heat exchanger and the first merging part, and a second flow rate adjusting unit is disposed in the heat medium circuit between the first branch part and the first heater core or between the first heater core and the first merging part. At least one of the first flow rate adjusting unit or the second flow rate adjusting unit is configured to optionally adjust the flow rate of the heat medium, and a controller controls the at least one of the first flow rate adjusting unit or the second flow rate adjusting unit.
