How to turn on the car heating and air conditioning?

How to turn on the car heating and air conditioning is as follows:

The main function of automobile air conditioning equipment is to improve the ventilation and adjust the temperature inside the car. Using sensors and filtering equipment to detect harmful substances can prevent dust or pollen that causes allergic reactions from entering the car. Automobile air conditioning system can cool and heat, and also has the option of internal and external air circulation.

The way to turn on the warm air function of automobile air conditioner is as follows: start the vehicle and let it idle for 5- 10 minutes, and the rest idle time will be extended accordingly in colder areas; Turn on the air conditioning system switch and turn off the air conditioning switch. Vehicles in the hot car state can be operated directly from the second step; Adjust the warm air temperature, air outlet direction and air volume, and select the external circulation mode. At this point, the heating operation is completed.

Demisting:

It should be pointed out that when the vehicle turns on the warm air, the window is very prone to fog. The solution is to turn one of the air outlets to the windshield and keep the external circulation. Being in the internal circulation mode for a long time may accelerate the fogging of the window. If the above operation fails to demist effectively, you should also turn on the forced demisting option to increase the temperature and increase the air volume blowing to the window.

The significance of automobile air conditioning equipment is also related to driving safety, and the "microclimate" in the car has an important influence on the driver's driving state. The research results show that when the car lacks fresh air, it will seriously affect the driving safety of the car.

A research report from the University of Siena in Italy pointed out that when there is no fresh air in the car for 45 minutes, drivers will feel tired and have difficulty concentrating, thus increasing the risk of traffic accidents.
