1 Answers
The symbol for the car air conditioning's external circulation mode is an arrow pointing into the car. Below is a relevant introduction about the car air conditioning's internal and external circulation modes: 1. External circulation: Simply put, it means expelling the air inside the car and drawing in fresh air from outside. The car uses a blower and fan to draw outside air into the interior. Therefore, if you use external circulation in heavy traffic, even with the windows closed, you can smell exhaust fumes. In dusty areas, using external circulation will bring in a dusty smell. 2. Internal circulation: Internal circulation prevents outside air from entering the car, and the air inside the car is recirculated. Another function is maintaining temperature. In summer, using internal circulation cools the car faster.
