Abstract: The refrigeration cycle device includes a compressor, an outside heat exchanger, a cooling pressure reducing unit, an evaporator, a branch portion, a cool down pressure reducing unit, a temperature adjusting unit, a merging portion, a bypass passage, and a first on-off valve. The temperature adjusting unit includes a temperature adjusting heat exchange unit and adjusts a temperature of a temperature adjustment target object. During a cooling and cool down mode, the outside heat exchanger functions as a radiator, and the evaporator and the temperature adjusting heat exchange unit function as heat absorbers. During a target object warm up mode, the refrigerant discharged from the compressor is guided to the temperature adjusting heat exchange unit via the bypass passage, and the heat of the discharged refrigerant is used as a heat source for heating the temperature adjustment target object.

Abstract: An air conditioner includes a heat medium circuit, a refrigerant cycle device, a discharge capacity controlling section, a heat generation amount controlling section, a target temperature determining section, and an upper limit determining section. The heat medium circuit includes a heating heat exchanger and an electric heater. The refrigerant cycle device exchanges heat between a heat medium in the heat medium circuit and a refrigerant discharged from an electric compressor. During a heater priority mode, the rotational speed of the compressor is increased to reach an upper limit and a heating amount of the heater is increased as a temperature difference increases. During a compressor priority mode, the heating amount of the heater is decreased and the rotational speed is increased to compensate for a decreasing amount.

Abstract: A thermal management device for a vehicle includes heat medium circuits, a reserve tank, and a connector. The heat medium circulates through the heat medium circuits separately. The reserve tank is configured to separate an air bubble contained in the heat medium from the heat medium. The connector allows the reserve tank to come in communication with the heat medium circuits selectively. As such, an occurrence of the heat loss in the degassing performed in the reserve tank can be suppressed with the thermal management device for a vehicle including the heat medium circuits.

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.
