inner loop mode
1. When there is a traffic jam, be sure to turn on the internal circulation mode of the air conditioner. Because the vehicle speed is slow and the distance between the vehicles is close, the concentration of exhaust gas in the air is high. At this time, using the internal circulation mode can effectively prevent the exhaust gas from outside the car from entering the car.
2． When driving in sandy or dusty weather, you should also turn on the internal circulation mode. This will not only prevent dust from outside the car from entering the car, but also reduce the impact of dust on the air conditioning filter element.
3. In the summer, when turning on the air conditioner for cooling, you should also use the internal circulation mode. This way, the cold air inside the car cannot go out, and the hot air outside the car cannot come in. This not only reduces the load on the air conditioner, but also improves the cooling effect.
External circulation mode
1. When the car windows are closed, the external circulation will help us a lot. Because some situations are not suitable for opening windows for ventilation, such as when a vehicle is driving at high speed. At this time, if the external circulation mode of the air conditioner is turned on, the air conditioner filter element can filter the outside air and allow clean air to enter the car.
2. On rainy days, using the external circulation mode can effectively remove the fog on the car glass.
3. New cars you just bought should also use the external circulation mode more often, which can help release harmful gases and remove odors in the car.
Internal and external circulation can be used flexibly
The use of internal and external circulation modes of automobile air conditioners is not static. We have to judge according to the actual situation.
In summer, go outside first and then inside: After the vehicle is exposed to the sun, harmful gases will be produced, and the temperature inside the vehicle will be much higher than outside the vehicle. Turning on the outside circulation first is beneficial to timely replacement of the air in the car, and the temperature inside the car will be quickly dropped, waiting for the air outlet Turning on the internal circulation after the temperature drops will cool the car faster and save fuel.
Switch between high-speed or long-distance use: When driving on high-speed or long-distance, if the internal circulation is used for a long time, the air in the car will become very poor. Therefore, the internal and external circulation modes should be frequently switched to update the air in the car in a timely manner.
