Should the AC be turned on when using the car air conditioner in summer?

When using the car air conditioner in summer, the AC should be turned on. The AC is the switch for the compressor. When the AC button is pressed, the temperature adjustment should be set to the blue position. For automatic air conditioning, you can set a temperature and then press the auto button, and the system will automatically adjust the interior temperature. The car air conditioning system includes not only the compressor but also the condenser, evaporator, expansion valve, etc. However, the compressor is one of the main components of the refrigeration system, responsible for compressing and transporting refrigerant vapor. To use the air conditioner, you should first turn on the fan, set the airflow to maximum, and use the external circulation to draw out the hot air inside the car. Then, turn on the AC for cooling. After about two minutes, you can switch to internal circulation. Once the interior temperature drops, you can temporarily turn off the AC cooling and turn it back on when the temperature rises again. This method can help reduce fuel consumption.
