Abstract: A thermal management system for a vehicle includes an engine cooling circuit that causes a heat medium to circulate through an engine, and an engine radiator that exchanges heat between the heat medium in the engine cooling circuit and outside air. The thermal management system for a vehicle further includes a switching device that switches between an independent mode in which the heat medium circulates respectively independently through a cooler cooling circuit and the engine cooling circuit, and a communication mode in which the cooler cooling circuit and the engine cooling circuit communicate with each other to cause the heat medium to flow between a chiller and the engine radiator; and a controller that controls an operation of the switching device to switch to the communication mode when a temperature of the heat medium in the engine cooling circuit is lower than a first heat-medium temperature.

Abstract: A vehicle air-conditioner has a casing, a first heat exchanger, and a second heat exchanger. The casing forms an air passage through which air flows toward inside of a vehicle cabin. The first heat exchanger is housed in the casing and performs a sensible heat exchange between the air flowing in the air passage and a heating medium. The second heat exchanger is housed in the casing and performs a sensible heat exchange between the heating medium and air that has exchanged sensible heat in the first heat exchanger. The first heat exchanger and the second heat exchanger respectively have a plurality of tubes through which the heating medium flows. A longitudinal direction of the plurality of tubes of the first heat exchanger and a longitudinal direction of the plurality of tubes of the second heat exchanger are the same direction as each other.

Abstract: A refrigeration cycle device for a vehicle has a compressor, a first pump, a high-pressure side heat exchanger, a heating medium-outside air heat exchanger, and a controller. The compressor draws and discharges a refrigerant. The first pump draws and discharges a first heating medium. The high-pressure side heat exchanger heats the first heating medium by exchanging heat between a high-pressure refrigerant discharged from the compressor and the first heating medium. The heating medium-outside air heat exchanger exchanges heat between the first heating medium and outside air. The controller controls operation of the compressor and the first pump. The controller activates the first pump when an activation request of the compressor is made. The controller activates the compressor, after activating the first pump, when it is determined or estimated that a temperature of the first heating medium is lower than or equal to a first predetermined value.
