What are the symbols for car air conditioning recirculation and fresh air mode?
2 Answers
The recirculation symbol is a circular arrow inside a car graphic; while the fresh air mode symbol shows an arrow entering the car from outside. Here are some explanations about car air recirculation and fresh air modes: 1. Function: Car recirculation means the air inside the vehicle is heated or cooled before being recirculated back into the cabin; fresh air mode means outside air is heated or cooled before entering the vehicle, achieving air exchange between inside and outside. 2. Recirculation mode: Recirculation mode closes the airflow passage between inside and outside the vehicle. Without the fan running, there's no airflow circulation. When the fan is on, the air drawn in comes only from inside the vehicle, creating internal air circulation. 3. Fresh air mode: Fresh air mode uses the fan to draw outside air into the vehicle, meaning there's an open air passage between outside and inside. The air blown by the fan comes from outside. Even without the fan running, moving the vehicle still draws in outside air to replenish fresh air inside.
I've driven quite a few cars, and the icons for the air conditioning system's recirculation and fresh air modes are quite common. The recirculation symbol usually features a small car outline with an arrow circling inside, indicating that the air only circulates within the car and no outside air enters. The fresh air mode symbol, on the other hand, shows an arrow from outside the car pointing inward, representing air being drawn from outside and circulated inside. I've found that in city traffic jams or when air quality is poor, turning on recirculation prevents exhaust fumes from entering the car and makes cooling more effective. When driving on the highway or if the car feels stuffy, switching to fresh air mode helps ventilate and remove odors, preventing dizziness. It's important to switch between them regularly—for example, using recirculation consistently during smoggy days protects health, while rainy days with heavy fog require fresh air mode to defog the windows, as blurred vision is too dangerous. From experience, these icons are simple and intuitive, and operating them isn't difficult—with a bit more practice, you can adapt flexibly to everyday driving conditions.
