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: 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: A refrigeration cycle device includes a compressor, a radiator, an air-conditioning heat exchanger, a cooling heat exchanger, an air-conditioning decompression unit, a cooler-unit decompression unit, a refrigerant flow rate detector, and a controller. The radiator is configured to radiate heat of refrigerant discharged from the compressor. The air-conditioning heat exchanger absorbs heat from air to evaporate the refrigerant. The cooling heat exchanger is arranged in parallel with the air-conditioning heat exchanger in the flow of refrigerant. The air-conditioning decompression unit adjusts a decompression amount of the refrigerant flowing into the air-conditioning heat exchanger. The cooler-unit decompression unit adjusts a decompression amount of the refrigerant flowing into the cooling heat exchanger. The controller controls the operation of the cooler-unit decompression unit so that the flow rate of the refrigerant detected by the refrigerant flow rate detector exceeds a predetermined reference flow rate.

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.

A refrigerant flow switching valve is provided to switch between a heat-medium cooling mode of cooling the heat medium in the heat medium-refrigerant heat exchanger, and a heat-medium heating mode of heating the heat medium in the heat medium-refrigerant heat exchanger. In addition, a heat medium flow switching device is provided such that, in the heat-medium cooling mode, the heat medium circulates between the heat medium-refrigerant heat exchanger and the cold-heat utilization device, and that in the heat-medium heating mode, the heat medium circulates between the heat medium-refrigerant heat exchanger and the hot-heat utilization device.

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.
