Title: VEHICLE AIR CONDITIONER
Abstract:
In this vehicle air conditioner, when the amount of heat absorbed by a vehicle exterior heat exchanger (33) is decreasing, a first hot gas heating operation mode is implemented in which refrigerant that is discharged from an electric compressor (30) is supplied to a downstream-side vehicle interior heat exchanger (31) and an upstream-side vehicle interior heat exchanger (32), the refrigerant is subsequently made to bypass the vehicle exterior heat exchanger (33) and decompressed, and is then sucked into the electric compressor (30).
