What are the signs of Magotan internal circulation and external circulation?

Pacific Auto Network Magotan external circulation sign is that a small car with an arrow enters the car through the front glass. If it is an arrow rotating in the car, it indicates the internal circulation sign.

Magotan's internal and external circulation signs are on the center console of the vehicle. The button is a car with an arrow passing through the front glass to indicate external circulation. If it is an arrow rotating in the car, it indicates the internal circulation sign. Automobile internal and external circulation refers to the way to adjust the air flow in the car by choosing whether the air conditioner inlet circulates in the car or enters the air from outside.

The external circulation state is that the air outside the car is sucked into the car by the fan, that is to say, the external air duct and the internal air duct are circulating, and the wind generated by the fan comes from outside the car. Even if the fan is not turned on, there is still airflow sucked into the car when the car is driving to supplement the fresh air in the car.

In the state of internal circulation, the airflow channels inside and outside the car are closed, so there is no airflow circulation without turning on the fan. When turning on the fan, the inhaled airflow only comes from the car, forming airflow circulation inside the car.

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