What are the differences between pure electric car air conditioning and traditional car air conditioning?

1, the way different

1, electric air conditioning: the use of vacuum control mechanism, elected air conditioning function keys when the temperature and air volume can be automatically controlled within a predetermined temperature.

2, traditional air conditioning: toggle the function keys on the control board to control the temperature, wind speed and wind direction.

2, the principle of different

1, electric air conditioning: combined power compressor driven by the motor, cooling performance by the HCU (hybrid control module) control motor speed that compressor speed to complete.

2, traditional air conditioning: traditional car compressor driven by the engine through the belt, cooling performance by the ECU to adjust the compressor swashplate angle to complete.

Three, the voltage is different

1, electric air conditioning: electric air conditioning compressor to use both 12V voltage for control, but also to use high voltage to drive the motor operation.

2, traditional air conditioning: traditional compressor only use 12V voltage control.
