ABSTRACT:
The air conditioning apparatus for electric automobiles includes a refrigerant cycle having a refrigerant compressor driven by an electric motor, a refrigerant pressure sensor for detecting the high-pressure-side pressure of the refrigerant cycle, and an air conditioner control apparatus. The rotational speed of the electric motor is determined on the basis of a variably controlled frequency. The refrigerant pressure sensor detects the pressure of the refrigerant compressed by the refrigerant compressor and flowing toward the heat exchanger for heating and outputs it to an air conditioner control apparatus. The air conditioner control apparatus controls an inverter on the basis of the value detected by the refrigerant pressure sensor.
