When is it appropriate to turn on the recirculation mode?
2 Answers
Recirculation mode is suitable to turn on during traffic congestion. Recirculation mode means that the air blown by the blower only circulates inside the car without any external air participation. After using recirculation mode, the cooling or heating effect is faster, and it can prevent external dust and harmful gases from entering the car. Common buttons for car air conditioning include the AC button, MAX AC button, front windshield defogging, rear windshield defogging, air direction control, recirculation mode, and fresh air mode. When turning on the air conditioning for cooling or heating, activate recirculation mode to quickly lower or raise the temperature inside the car. Once the temperature stabilizes, appropriately switch to fresh air mode to exchange air with the outside.
I think about using the recirculation mode every day. When stuck in traffic with heavy exhaust fumes, turning on recirculation is a must – inhaling those harmful gases really damages your health. On highways, when passing through tunnels or construction zones with dust everywhere, switching to recirculation is also necessary. Keeping the windows tightly closed reduces the amount of dirt you breathe in. If you want to cool down or warm up the car quickly with the AC on, recirculation is much more efficient, getting the temperature comfortable in just ten minutes. But a word of caution: using recirculation on rainy days can easily cause fogging on the windows, making it hard to see the road. In such cases, you should switch to fresh air mode to ventilate. During normal city driving, switch to fresh air mode every half hour to get some fresh air and avoid feeling stuffy. The key is to flexibly switch between these two functions based on road conditions – that’s the most reliable approach.
