Nowadays, the temperature is getting higher and higher. Even in the morning, you can feel the obvious heat wave. In this environment, the car owner will turn on the car air conditioner. But are you really using it right? These misunderstandings about the use of time and space adjustment during driving in summer are often committed by even old drivers with years of car age.

Misunderstanding 1. Always open internal circulation mode

After the internal circulation mode of the air conditioner is turned on, the air replacement inside and outside the vehicle will be stopped. The air outside the vehicle cannot enter the vehicle, and the air inside the vehicle cannot be discharged outside the vehicle. Using this mode for a long time is likely to cause poor air circulation, and the drivers and passengers are prone to feel dizzy and chest tightness, affecting the ride comfort. If it is serious, it will lead to carbon monoxide poisoning among drivers and passengers, threatening life and health.

Therefore, when driving in summer, car owners should recycle the internal and external circulation, not always drive the internal circulation, but pay attention to the circulation of air inside and outside the car.

Myth 2: turn on the air conditioner immediately after the car is exposed to high temperature

In summer, not all car owners will choose to park their cars in the underground parking lot. Some car owners park their vehicles in the open parking lot for other reasons such as saving time and trouble. When the car is exposed to the sun, some car owners will immediately turn on the air conditioner. In fact, this method is very wrong, which is easy to aggravate the load of vehicle engine and shorten its service life.

The correct way is that the owner should open the window or door first to let some of the hot air in the car dissipate. When the owner feels that the temperature inside the car has decreased significantly, he can close the windows and doors, and then turn on the air conditioner for cooling.

Misunderstanding 3. Random adjustment of wind direction

After the on-board air conditioner is turned on, the temperature in the car will be reduced to a certain extent, making the drivers and passengers feel cool. However, some car owners will adjust the wind direction at will after turning on the air conditioner, and even adjust the air outlets of each air conditioner to different directions, trying to accelerate the reduction of the temperature in the car in this way.

In fact, this approach is not desirable. Because the cold air is heavier than the hot air, if you want to reduce the temperature in the car faster, you should wind all the air outlets upward.
