What is the external circulation symbol for vehicle air conditioning?
2 Answers
The button with an arrow pointing directly from outside the vehicle represents the external air circulation mode when pressed, indicating that air is drawn from outside. The button with an arrow inside the vehicle represents the internal circulation mode when pressed, meaning the air circulates within the car. Using external circulation allows you to breathe fresh air from outside. Additional information: Below are precautions for using car air conditioning: 1. Do not set the temperature too low. 2. Control the direction of the air vents. 3. Avoid prolonged use. 4. Occasionally use higher fan speeds. 5. Turn off the air conditioning when driving at low speeds.
The symbol for the car air conditioning's external circulation mode looks like a small car icon with an arrow pointing from the outside into the car, somewhat resembling the flow of outside air into the vehicle. Having driven many cars, I've noticed the button is usually located in the middle of the air conditioning control panel. Pressing it switches between internal and external circulation modes. Personally, I prefer using external circulation when driving in the city or when the air quality is good. It allows fresh air to enter, reducing stuffy odors and significantly improving ventilation inside the car, which helps prevent drowsiness during long drives. On rainy or foggy days, switching to external circulation can also prevent window fogging, enhancing safety. Fellow drivers should pay attention to the location of this symbol; with a few uses, you'll get familiar with it. It's also important to keep the air conditioning system clean—don't let a clogged filter affect your experience. Regular checks can help reduce malfunctions.
