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.

Abstract: A control apparatus is applied to a system including an engine and a compressor for air-conditioning, and adjusts an operating point of the engine when the engine is operated. The control apparatus determines whether or not to allow increase in engine output to drive a compressor based on an air-conditioning request, based on the operating point of the engine before driving of the compressor in relation to a predetermined high-efficiency region including a maximum efficiency point in an efficiency characteristics of the engine, when the compressor is driven in response to the air-conditioning request. The control apparatus controls the engine output such that the operating point of the engine is in the high-efficiency region, if the increase in engine output is determined to be allowed.
