[Problem] To provide a heat pump vehicle air conditioner that implements comfortable heating in a vehicle interior during travel and prolongs traveling distance by preventing or suppressing frost on an exterior heat exchanger when heating the vehicle interior in advance while the vehicle is plugged in. [Solution] The invention is provided with an injection circuit (40) that diverts a refrigerant which has exited a heat dissipater (4) and returns the refrigerant to a compression midpoint of a compressor (2). A controller has a frost estimation means that estimates frost on an exterior heat exchanger (7) and, in a heating mode which is implemented when electricity is supplied from an external power source to the compressor (2) or to a battery that supplies power in order to drive the compressor (2), the controller injects gas to the compressor (2) via the injection circuit (40) when frost on the exterior heat exchanger (7) is predicted.
