How to Use the Interior and Exterior Air Circulation in a Car?
1 Answers
The usage of interior and exterior air circulation in a car is as follows: 1. Exterior Air Circulation Usage: By using the exterior air circulation, you can breathe fresh air from outside the car. When driving at high speeds for a long time, the air inside the car may become stale, making passengers uncomfortable. If you cannot open the windows, you should use the exterior air circulation to let in some fresh air. In winter, if the warm air feels too hot, you can turn off the fan and open the exterior air circulation to maintain the interior temperature while still getting fresh air, making the ride more comfortable. 2. Interior Air Circulation Usage: When the air conditioning is on and the interior temperature is higher than the exterior temperature, the front windshield may fog up. In this case, you should turn on the exterior air circulation to achieve a defogging effect.
