In winter, the temperature outside is very low. Sometimes when the car is parked downstairs for one night, the windows are easy to freeze. So how to prevent the windows from fogging and freezing? For the car owners, this is a problem that must be understood.
Why do windows fog
In winter, when the temperature difference between the inside and outside of the car is large, the water saturated vapor pressure on the low-temperature surface is lower than that of the surrounding environment, and the water vapor will gather on the surface of the glass to form a mist in the form of tiny water droplets. In short, when the temperature difference between the inside and outside of the vehicle is large, the side with high window temperature will condense the water in the air, and a layer of fog will appear. In autumn and winter, the foggy windows are usually the cause.
How to prevent the windows from frosting in winter:
1. Put out the hot gas in the car after flameout
After driving and parking, you can open the door for a few minutes to release the temperature inside the car, wait for the temperature inside and outside the car to equalize and then close the door to lock the car, which can reduce the probability of frosting in the morning.
2. The car is parked in the sun
In winter, it's better to park in the sunny place. A higher external temperature can reduce the probability of frost formation. In the cool place, not only frost formation but also ice formation is possible.
3. Park the car in the garage
The temperature of the garage must be higher than that of the outside. If you park it in the garage, there will be no frost and ice, and it will also prevent theft and face to face the impact of bad weather.
4. Using the car cover
You can buy a car suit to cover the car. If you open the car cover in the morning, there will be no frost on the car glass. Although it is troublesome, the effect is obvious.
5. Wipe with hot towel
It is not recommended to use hot water to pour directly on the glass, so the damage to the glass is very big. You can try to wipe it with a hot towel, and the frost will melt soon.
6. Heating can also be used
Start the car to use the heating, set the gear to the glass gear, blow for a few minutes, the frost will melt automatically, and then use the wiper to clean it.
What to do if the windows are frosted in winter:
1. Manual scraping with hard objects
The owner can prepare a hard plastic blade, of course, can also use a special glass frost shovel, which is more convenient, faster, and does not freeze hands. When there is snow and ice on the glass, use a plastic scraper or glass frost shovel to remove it.
But it must be noted that when removing ice and snow, it is necessary to prevent the glass from being scratched. The plastic blade or glass frost shovel cannot be scratched back and forth, and should be pushed in the same direction.
2. Turn off the air conditioner after parking
Adjust the air duct of the air conditioner to the external circulation state and then close it, or even operate the air conditioner in the external circulation + low temperature setting state for a period of time, so that the temperature in the car can be reduced to the extent that there is no condensation water in the window, but it is not recommended to open a gap in the window, because in the public parking environment, the gap left in the window will not only contaminate the interior of our car, but also may cause the car Loss of property within.
