Is the correct way to use the air recirculation to press and light up?
1 Answers
When the button is pressed and the indicator light is on, it means the air recirculation is activated, and when the indicator light is off, it means the external air circulation is activated. The default ventilation starts with the external air circulation. Here is additional information: 1. Air recirculation: Air recirculation is a state of the car's air conditioning system. In this state, the air exchange channels between the inside and outside of the car are closed. When the fan is off, the airflow inside the car does not circulate, and when the fan is on, the incoming airflow comes only from inside the car, forming an internal airflow circulation. 2. External air circulation: External air circulation refers to the car's air conditioning system opening to allow air from outside the car to circulate inside the vehicle.
