It is better to use the external circulation when turning on the car's air conditioning. Setting the air conditioning to internal circulation mode will cause the temperature inside the car to rise quickly. After the car becomes warm, switch to external circulation to help with air circulation inside the vehicle. The functions of car air conditioning are: 1. Achieving a cooling effect through the continuous phase change cycle of the refrigerant; 2. Removing dust, odors, smoke, and toxic gases from the air inside the car, making the air fresher and increasing the relative humidity inside the vehicle. Methods for using and maintaining car air conditioning include: 1. Do not set the temperature too low; 2. Control the direction of the air vents; 3. Avoid prolonged use; 4. Occasionally turn on high fan speed; 5. Turn off the air conditioning when driving at low speeds.
