The fog fog in the car window will appear in the four seasons，Because the temperature difference between inside and outside will always exist，The common fog location and solution have the following three standards。

Summer rainy driving will always appear inner fog in the front gear，This state seems to be difficult to solve。Because of the fog, the rainwater continued to cool down from the outside of the window glass，The temperature in the rainy days is generally low，Using cold air conditioners in the car will make the experience bad。

At this time, most users will choose to turn off the cold air conditioner，The result will cause the internal air temperature to be lower than the outside of the car，To the temperature below the front -block window that is continuously cooled，Fog will inevitably appear in the front gear。

The concept of fog refers to the water vapor in the air condensed into a subtle water drop，It can be understood as the air humidity is too large、Water vapor liquefied suspension caused by the ability of the air itself to carry aquatic molecule。General window glass does not have "driving water"，The air will condense when the air is exposed to the glass;

And the water vapor will be condensed when it is cold，Low -temperature front -block glass is the best "landing point"seabet my。So the front is always blocked in rainy days，So you only use only one way to solve the fog at this time -drying。

Processing method: Generally drying the effect of hot air is the best，But the use of warm wind in summer will make it difficult for drivers and passengers to endure。Therefore, there is only "low -efficiency drying" with cold winds to continue using cold winds，but the actual effect is not good;

Because the cold wind will reduce the air temperature in the car，The lower its temperature, the worse the ability to carry water vapor，So the lower the air temperature closer to the front gear, the worse the ability to condense the fog。So the correct fog windshield should be "front block hair dryer"，or "front block plus foot"。

Driving the front gear in normal weather in summer will also fog，At this time, many drivers will deliberately adjust to "front -resistance fog" windshield，But the degree of fog is getting more and more exaggerated。The reason lies in the error understanding of the principle of fog，Because the concept of the fog at this time is from the rainy days "opposite inside and outside"。

High temperature weather in summer will make the air temperature high，The ability of external air to carry water will naturally be strong。Always use cold air conditioning when driving，The circulation flow of cold wind in the car will continue to cool down the window "from the inside out"; the result is naturally after the water vapor of the external air encounters a low -temperature window，Condensed into a water droplet。

The outer fog solution of the front window and the side window is very simple:Clean the wiper with a front gear，The side window lifting can effectively remove water and fog。The windshield in the car does not need to be adjusted deliberately，Because the density of the cold air is greater than the warm air in the seabet iocar，So the cold wind blowing out is sinking; blowing the upper body directly will feel "the wind is too hard"，The best experience is to remove fog windshield with front gears，Use the gentle cooling of air flow。

The reason for the fog in the car in winter is exactly the same as the fog in summer rainy days，Because low temperature air will continue to cool down the window during driving。

The so -called "wind resistance" can be understood as air resistance，Under the action of gravity, the air will cover the surface without dead ends; the car is actually constantly impacted and pushed away the air，So low -temperature air will naturally continue to cool down the body and windows。At this time, the window temperature is low、High temperature in the car，The air with a large internal humidity will be condensed in front of the water fog，Of course, the solution is to dry it with warm air.

Use "warm air + front gear removal" windshield，At the beginning, there will be fog aging，The reason is that the changes in air temperature strengthen the ability to condense water mist。

But the effect will be better and better afterwards，It takes time because of the heating of the front block，The temperature slows down to reduce the condensation ability; at the same time, the continuous hair dryer of the warm air can also accelerate the drying effect，So using warm air is the best way to drive for a long time。

As for the cold wind, although it can be quickly divorced，But as long as you close it, you will get fog quickly，This method should not be used in winter。，The rear gear is heated with resistance wires can be opened and used directly)

The above is the content of the window and the fog，I hope it can help all the owners and friends。
