Abstract: A refrigeration cycle device includes: a first expansion valve that decompresses a refrigerant flowing out of a high-pressure side heat exchanger; an exterior heat exchanger that exchanges heat between the refrigerant flowing out of the first expansion valve and outside air; a second expansion valve that decompresses the refrigerant flowing out of the exterior heat exchanger; a low-pressure side heat exchanger arranged in series with the exterior heat exchanger; a cooler core that exchanges heat between the heat medium cooled by the low-pressure side heat exchanger and air to be blown into a vehicle interior to cool the air; and a controller configured to switch between a heat absorption mode and a heat dissipation mode by adjusting an amount of decompression in each of the first expansion valve and the second expansion valve.

Abstract: A vehicular heat management system includes a heat medium circuit, a heat source portion, and a device. A heat medium cooling an engine circulates in the heat medium circuit. The heat source portion heats the heat medium. The device is configured to function and heat the heat medium when the heat medium flowing into the device is at or above a predetermined temperature. When the engine is being warmed up, heat generated by the heat source portion is supplied to the device in preference to the engine. According to this, since the heat generated by the heat source portion is supplied to the device in preference to the engine when the engine is being warmed up, the engine can be warmed up early.

Abstract: In a thermal management system for a vehicle, a first switching valve is connected to at least one device in a group of a plurality of devices, a heat medium discharge side of a first pump, and a heat medium discharge side of a second pump in parallel with each other; and a second switching valve is connected to at least one device in the device group, a heat medium suction side of the first pump, and a heat medium suction side of the second pump in parallel with each other. Heat medium circulating through a first device included in the device group allows to flow through the second device. One side of a heat medium inlet side and a heat medium outlet side of the second device is connected to between one of the first switching valve and the second switching valve and the first device.

Abstract: A vehicular heat management system has a compressor, a heat-medium heating heat exchanger, and a flow adjustment part. The compressor draws and discharges a refrigerant. The heat-medium heating heat exchanger causes a heat exchange between the refrigerant discharged from the compressor and a heat medium other than air and heats the heat medium. The flow adjustment part causes a flow of a cooling fluid cooling the refrigerant when the compressor is stopped. The vehicular heat management system further has a refrigeration cycle unit and a refrigerant-flow-path forming member. The refrigeration cycle unit includes devices configuring a refrigeration cycle. The refrigerant-flow-path forming member (i) is disposed in a low-temperature area having an air temperature that is lower than an air temperature in an area in which the refrigeration cycle unit is disposed, and (ii) passes a refrigerant in the refrigeration cycle flows.

Abstract: A first-pump arrangement flow path, temperature-adjustment target-device arrangement flow paths, and a second-pump arrangement flow path are connected to a communication flow path in this order from one end side to the other end side of the communication flow path. A first heat exchanger is disposed in the first-pump arrangement flow path among numerous flow paths, which is connected to the communication flow path at a position on a side of the first-pump arrangement flow path, rather than the flow path in which a second heat exchanger is disposed. The switching portion is operated to establish communication between plural flow paths, starting from the flow path connected to the communication flow path at the position closest to the one end side among the numerous flow paths, up to the flow path connected to the communication flow path at an n-th position counted from the one end side among the numerous flow paths.

Abstract: A first heat transfer medium circuit includes a first path and a second heat transfer medium circuit includes a second path are formed independently from each other by operating a first switching valve and a second switching valve in conjunction with each other to make each of multiple flow passages of a first flow passage group communicate with either the first path or the second path. The first and second heat transfer medium circuits in which the first path and the second path are connected to each other in series is formed by operating the first switching valve and the second switching valve in conjunction with each other to make each of the multiple flow passages of the first flow passage group communicate with both the first path and the second path.
