To improve restartability, immediately after a motor driven compressor is stopped, without using an equalizing valve by providing a control means for operating a motor driven fan, even after the compressor has stopped.
When an air conditioner switch 9 is closed, a motor driven fan 3 and a blower fan 6 are operated based on a command from an air conditioning controller 8, and an inverter 10 applies an AC voltage to a motor portion 103 of a motor driven compressor 1. The portion 103 receives its voltage and drives a compressor mechanism section 100. The mechanism section 100 sucks and compresses a refrigerant, and discharges the refrigerant to a condenser 2 side. A gas refrigerator fed under pressure to the condenser 2 is heat exchange with an atmosphere fed under pressure by a motor driven fan 3, condensed, liquefied, and pressure reduced by a pressure reducing unit 4 to become a vapor- liquid phase, and the vapor-liquid phase refrigerant is fed to an evaporator 5. The evaporator 5 heat exchanges the vapor-liquid phase refrigerant with air condensed air supplied by the fan 6 to cool in a compartment by the cooled conditioned air.
