The weather is getting hot, how to open the windows to let the heat out of the car as soon as possible when driving in the city? Open all the windows or crank up the air conditioner? Are these the best methods?

Generally, there are 4 windows on a car, and the sunroof is 5. There are many tricks in it, and the method of opening is also exquisite. Let's take a look!

all windows open

Many people think that opening all the windows is the best way to ventilate.

actually not. If the windows are fully opened, a large amount of air is poured into the cabin, and the exhaust speed is not as fast as the intake speed. The experience is not good either. Therefore, it is best not to use this kind of window opening for ventilation during driving.

Open one side front window

The main purpose of opening the one-side window in the front row is to dissipate the smell in the car. Friends who smoke should understand better: when smoking, open the window on your side a little bit, and use the principle of negative pressure, second-hand smoke will be quickly discharge. However, it is not advisable to open them all. If the airflow is fully opened, the air will be poured into the car, and the smell of smoke will run all over the car.

The editor here reminds you: Smoking while driving is distracted driving, please do not smoke while driving!

Open the same side window

If you open the front and rear windows on the same side at the same time, the wind is definitely strong. However, there is a hidden danger in this way of opening the window, that is, it affects the lateral stability of the vehicle. Air enters from one side, and the pressure inside the car is unbalanced.

Especially when driving at high speed, it is difficult to control the direction, and the passengers on the other side will feel particularly strong against the wind. If stones or garbage fly into it, it is very likely to cause injury to the passengers. Therefore, when driving on the highway, do not open the two windows on the same side at the same time.

Close one side front window and open the remaining three windows

If you close the front window on one side, the air flow will have a clear sense of direction, and the air will circulate quickly. If there are no passengers in the car, this method is very suitable for removing heat and odors. However, if there are passengers in the car, it is still easy to be blown by strong winds.

Close the rear window on one side and open the remaining three windows

When the one-side rear window is closed, the air in the rear row will gather a lot to form a high-pressure area, and then be discharged from the other side of the open window and the exhaust port. This method does not leave the passenger with the feeling of being blown, which is both comfortable and airy.

Note: If there is a skylight, you only need to open the skylight a little, and the negative pressure can also be used for quick ventilation. But don't open it too much, otherwise the effect will be bad and the noise will be loud.

Open front and rear diagonal windows

We all know the draft when we open the windows at home. The same is true for driving windows in the car. When the air enters from the front window and the air enters from the rear window, it forms a "small whirlwind". This air flow is very soft and will not make passengers feel uncomfortable. heat.
