Abstract
There is disclosed a vehicle air conditioner of a heat pump system in which there is prevented or inhibited frosting to an outdoor heat exchanger when heating in a vehicle interior is beforehand performed during plug-in, thereby achieving comfortable heating in the vehicle interior during running and also extending a running distance. The vehicle air conditioner includes an injection circuitwhich distributes a refrigerant flowing out from a radiatorto return the refrigerant to the middle of compression by a compressor, a controller has frosting estimation means for estimating the frosting to an outdoor heat exchanger, and when a heating mode is executed in a state where a power is supplied from an external power source to the compressoror to a battery which supplies the power to drive the compressor, the injection circuitperforms gas injection to the compressorin a case where the frosting to the outdoor heat exchangeris predicted.
