Where are the Binzhi internal circulation and external circulation switches?

Just press the button below to adjust the wind speed. The specific position is as follows: The internal circulation state is that the air flow channels inside and outside the car are closed, and there is no air flow circulation without turning on the fan. When turning on the fan, the air flow inhaled only comes from the car, forming air flow circulation inside the car.

The main purpose of internal circulation is to prevent external dust and harmful gases from entering the car in time and effectively, for example, when driving through smoke, dust, odor areas or dense and compact vehicles, to prevent harmful tail gas discharged by the preceding car. Another function is to keep warm.

The function of external circulation is to use external circulation to breathe fresh air outside the car. Driving at high speed, after a long time, I feel that the air inside the car is turbid, people are uncomfortable, and I can't open the window, so I use the external circulation to bring in the breeze; It is too hot to send warm air in winter, so you can turn off the fan, turn on the external circulation, keep the temperature inside the car, and feel more comfortable with fresh air.

The function of external circulation is to connect the air inside and outside the car, so as to achieve the purpose of supplementing fresh air. If the external circulation is turned on, the air inside and outside the car is connected. When the vehicle is driving, the airflow will be automatically sucked into the vehicle by the wind pressure.

When the vehicle is stationary, the air outside the vehicle can enter the blower along the air duct, and then be blown into the vehicle by the blower, and the air entering the vehicle is discharged from the exhaust hole at the rear of the carriage, thus achieving the effect of circulation.
