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 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 switching valve configured to switch between a battery mode in which refrigerant flows to a battery heat exchanger and a non-battery mode in which the refrigerant bypasses the battery heat exchanger; and a controller controlling a compressor and the switching valve. The controller includes an estimation unit configured to estimate an oil stagnation amount, which is an amount of lubricating oil accumulated in the battery heat exchanger in accordance with execution of the non-battery mode. The controller includes a determination unit configured to determine whether lubricating oil in the battery heat exchanger needs to be recovered on the basis of the oil stagnation amount. The controller includes an execution unit configured to execute an oil recovery mode for recovery of lubricating oil in the battery heat exchanger when the determination unit determines that lubricating oil needs to be recovered.
