Mistakes in the use of automobile air conditioners

Myth 1: The air conditioner is always on at low speed.

The correct way: turn on the air conditioner in the car, most people will not open it to the maximum gear, thinking it will cost money. Of course, there is nothing wrong with this idea, but air conditioners will inhale a lot of dust and form dirt when they are used. It will get moldy after a long time, and then it will be distributed to the car through air conditioning, which is easy for people to inhale. Therefore, we should always set the air conditioner to the maximum gear and blow out the scale in the air conditioner through strong wind.

Myth 2: Turn on the air conditioner as soon as you enter the carriage.

Correct way: As we all know, the temperature in the car may be higher than that in the car under the scorching sun, so when you get on the bus, you should first open the car and the window to let the hot air out. Then, open the external circulation of the air conditioner to reduce the temperature difference between the inside and outside of the car. Then, open the internal circulation again, and close the air door when the temperature inside the car reaches the normal and comfortable state. Finally, before leaving, carefully check whether the exhaust system leaks.

Myth 3: Turn off the air conditioner after the flameout.

The correct way: it is also the habit of many people not to turn off the air conditioner until they reach their destination. However, the consequences of this will lead to the spread of mold in air conditioners due to humidity. Therefore, the air conditioner should be turned off a few minutes before parking, and then the natural wind should be turned on later to keep the air conditioning system relatively dry and avoid mold propagation.

Myth # 4: Air conditioning winds blow at will.

The correct way: some people don't pay much attention to it. After turning on the air conditioner, let the wind direction of the air conditioner blow at will. According to the principle that cold air sinks and hot air rises, it is wrong to do so. We should raise the air outlet of the air conditioner, so that the cooling effect will be better.

Myth 5: stop and turn on the air conditioner to rest.

The correct way: In summer, I often see some people park their cars on the side of the road and turn on the air conditioner for a while, but I don't know that this is suicide. No matter how long it stops, after the air conditioner is turned on for a while, you must open the window to let the air convection and let there be enough fresh air in the car. The driving process is the same. If the air is not changed for a long time, the chances of poisoning will be higher. Therefore, when you turn on the air conditioner for a long time, you must always open the window or let the air conditioner have a rest, which can save fuel!
