How to defrost the car in rainy days? The windshield is foggy.

1, the fog in the car is not big, so you can open a gap in the windows on both sides, so that the air inside and outside the car will form convection, the temperature difference will be reduced, and the fog will gradually disappear. The principle of this method is the same as turning on the air conditioner, but it does not increase fuel consumption. The disadvantage of window convection is very obvious, which is not available in rainy and snowy weather, expressway and foggy weather. Opening the window will reduce the temperature inside the car.

Extended data:

The reason for the fog is that the water vapor in the car meets the cold glass and forms a thin layer of water vapor condensate. Therefore, to remove the fog on the windshield of a car, it is necessary to increase the temperature of the glass or reduce the humidity inside the car.

Therefore, when people leave the car, wait a while, open the window to ventilate the car, so that when the temperature difference between the inside and outside of the car is not big, lock the car and leave. The purpose of defogging is to improve driving safety, so it should be noted that no matter which method is used to defog, it must be carried out before driving.
