Which is the Recirculation Mode in Car Air Conditioning?
1 Answers
The symbol for air recirculation is: a car icon + an arrow turning inside the vehicle. Below is an introduction to the car's recirculation and fresh air modes: 1. Usage: Use recirculation mode in traffic jams and fresh air mode on highways. The use of recirculation and fresh air modes should be combined with the air conditioning and heating system. By using the fresh air mode, you can breathe fresh air from outside the car. When driving on highways for a long time, the air inside the car can become stuffy and uncomfortable, and you can't open the windows. In this case, you should use the fresh air mode to let in some fresh air. If the warm air in winter feels too hot, you can turn off the fan and switch to fresh air mode, maintaining the temperature inside the car while getting fresh air, which will feel more comfortable. 2. Principle: The recirculation mode closes the airflow channel between the inside and outside of the car. Without the fan, there is no airflow circulation. When the fan is turned on, the airflow drawn in comes only from inside the car, creating an internal airflow cycle within the vehicle.
