<p>Provided is a vehicle air conditioning device which is capable of promptly heating the interior of a vehicle even immediately after a vehicle driving source is started, thus having satisfactory instant heating properties. On that side of a compressor (7) where a suction port (7a) is located, the vehicle air conditioning device (1) comprises an exhaust-heat heat exchanger (20) for supplying exhaust heat of an engine (15) to low-pressure refrigerant on that side of the compressor (7) where the suction port (7a) is located. In an early stage of start of the engine (15), the exhaust heat generated by the engine (15) is supplied by the exhaust-heat heat exchanger (20) to the low-pressure refrigerant on that side of the compressor (7) where the suction port (7a) is located, with the result that the low-pressure refrigerant on that side of the compressor (7) where the suction port (7a) is located, is heated.</p> |
