How to remove the fog on the car glass in cold winter?
Another method is window convection, air convection inside the car, the temperature inside the car slowly approaches the temperature outside the car, and the fog will disperse. The advantage is that the air conditioner can be turned on without increasing fuel consumption, but this method can not be used in all situations, such as cold winter and rainy days. The above defogging methods are all temporary solutions, but they can't completely solve the problem of fogging, and people in the car will also be affected.
If we want to solve this problem, we must analyze the reasons. The reason why the window is foggy is that it is hot inside and cold outside. The temperature difference between the inside and outside of the car 10 to 20 degrees Celsius, the hot air exhaled by the occupants in the car will condense into water vapor when it meets the cold glass and condense on the window. This is an old problem, but it is not a small problem, because once the driving line of sight is blocked, it can't be seen clearly for a few seconds.
The correct way to turn it on: The first step is to stop (the moving vehicle must pull over) and turn on the warm air. Because hot air is turned on when the glass is foggy when driving, the fog on the glass will become more and more serious, especially in rainy days, when there is a lot of moisture in the air, the front windshield will suddenly become frosted glass, which is very dangerous! Therefore, the editor suggested that it is best not to try to blow the glass with hot air when driving. It is best to blow the glass with hot air before driving until it is dry.
Step 2, turn up the warm air temperature (the higher the better) and wait for 3-5 minutes. It takes a long time to demist with warm air. When you first open it, it will really make the fog inside the glass bigger. This is because the temperature difference between inside and outside is large. After hot air dries the moisture in the car, the glass will become transparent, and it will be fine in a few minutes.
Thirdly, after the fog inside the glass is completely dried, the temperature is lowered. Because the car is dry, it will not fog again during driving, and it can be adjusted to a temperature that the human body feels comfortable.
