Abstract
A vehicle air conditioner comprising a heat pump device including a compressor that compresses refrigerant, first and second heat exchangers disposed inside the vehicle cabin within an interior air-conditioning unit, and a pressure reducing valve. The vehicle air conditioner further comprises an air-conditioning controller which controls the heat pump device and interior air-conditioning unit, an exterior heat exchanger temperature sensor and a degree-of-heating requested detecting section. If the quantity of heat absorbed by the exterior heat exchanger has decreased, the controller operates the heat pump device to operate in a mode in which a refrigerant discharged from the compressor flows through the first and second heat exchangers, bypasses the exterior heat exchanger, and then is sucked into the compressor, and a second mode in which the refrigerant is flow throughs the first heat exchanger and is bypassed around the second and exterior heat exchanger after pressure has been reduced.
