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: 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.

Abstract: A first refrigeration cycle includes a first compressor, a first radiator, an air-conditioning expansion valve, an air-conditioning evaporator, a first expansion valve, and a first evaporator. In the first refrigeration cycle, a first refrigerant evaporates in at least one of the air-conditioning evaporator or the first evaporator. A second refrigeration cycle includes a second compressor, a second radiator, a second expansion valve, and a second evaporator. A heat transfer portion switches a heat radiation destination from the first radiator to a second refrigerant in the second evaporator or outside air. In the air-conditioning evaporator, the first refrigerant absorbs heat from ventilation air blown into a space to be air conditioned as the first refrigerant evaporates. In the first evaporator, the first refrigerant absorbs heat from the outside air as the first refrigerant evaporates. In the second radiator, the second radiator radiates heat from the second refrigerant to the ventilation air.
