The present invention concerns an on-vehicle air-conditioner, resolving problems of the prior art, and allowing to perform cooling, heating, dehumidification or others efficiently even for vehicles of low waste heat, such as hybrid cars taking electricity and gasoline as energy source, idle stop coping cars or battery cars taking only electricity as energy source, or other vehicles, by cooling by loading a refrigeration circuit, using for example CO2refrigerant, and provided with an electrically driven two-stage compression system compressor, and at the same time, installing a refrigerant heat exchanger for cooling the refrigerant, compressed in the first stage in a way to exchange heat with the car interior air, and using conveniently also for heating together with the heat of the cooling water for cooling the engine.
