Abstract: A cooling water circuit includes: a heat-radiating heat exchanger in which a cooling water is heated by heat radiated from an external heat medium; a heat-absorbing heat exchanger in which a cooling water is cooled by heat absorbed by an external heat medium; and a first heat exchanger and a second heat exchanger in which heat is exchanged between the cooling water and outside air. When a high-temperature cooling water heated by the heat-radiating heat exchanger flows through the first heat exchanger and the second heat exchanger, the first heat exchanger and the second heat exchanger are arranged in series for the cooling water to flow. When a low-temperature cooling water cooled by the heat-absorbing heat exchanger flows through the first heat exchanger and the second heat exchanger, the first heat exchanger and the second heat exchanger are arranged in parallel for the cooling water to flow.

Abstract: In a heat pump system, when a heat-shock determination portion determines that a difference between a coolant temperature in a coolant flow path and a coolant temperature in a heat source flow path is equal to or higher than a predetermined temperature, a flow-path switching portion mixes the respective coolants flowing through at least a bypass flow path and the heat source flow path together to flow into the coolant flow path.

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.
