How to Turn on the Air Conditioner's External Circulation?
2 Answers
Air conditioner external circulation activation method: Locate the button with a car symbol in the air conditioning control area; the button featuring an arrow pointing from outside the car to the inside is the one for activating external circulation. Press this button to turn on the external circulation. Below is information about air conditioner circulation modes: 1. External Circulation: The car uses a fan to expel the air inside the vehicle and then utilizes the suction of the blower to draw in outside air. It is advised not to activate the external circulation when the outside air quality is poor. 2. Internal Circulation: Internal circulation maintains the original air inside the car in circulation, isolating it from the outside air. Turning on internal circulation can help maintain temperature, and in summer, it cools the car interior faster. However, if internal circulation is used with windows closed for an extended period, the car interior will quickly fill with moisture from human respiration, and oxygen levels will decrease.
I haven’t been driving for long, and when I first started driving on my own, I didn’t know how to use the air recirculation function. Later, I found out that it’s just a button on the dashboard with a small car icon pointing outward—just press it lightly to turn it on. Sometimes, opening the windows creates too much wind and noise, especially on highways, so using the air recirculation mode makes things much quieter while still letting in fresh air, which feels more comfortable than the internal circulation mode. In city traffic, if the air is clean, turning on air recirculation for ventilation is great, but in heavily polluted areas, be careful not to inhale too much dirty air. For cars with automatic climate control, the operation is similar—pressing the air recirculation button doesn’t affect other settings, and you can easily confirm it’s on by checking the indicator light on the dashboard. It’s quite convenient.
