Winter is coming, the most troublesome thing for car owners is the front windshield fogging, the reason for the fogging of the front windshield is that the temperature difference between the inside and outside of the car is large, the temperature of the window is very low, when the car enters the person, the exhaled water vapor stains the cold front windshield, which is instantly liquefied, forming a layer of mist, thus affecting the owner's driving vision. For this fog, how should car owners effectively remove it? "Automotive Profile" introduces four methods, I hope all owners keep in mind!
Turn on the one-click defogging button
Car air conditioning has a function is a key to remove fog, as shown in the following figure, when the owner opens a key defogging function, the air conditioner will blow out the air will be blown directly to the front windshield, strong air convection is conducive to washing the fog on the surface of the front windshield, thereby significantly increasing the purification effect of the front windshield, at this time, the larger the air conditioning air volume, the better the window defogging effect.
Especially after the vehicle is driven for a long time, the engine water temperature rises, and the air blown out by the air conditioner is hot air, and the hot air can quickly heat the water mist on the surface of the front windshield, thereby increasing the defogging effect of the vehicle.
Turn on the AC button for air conditioning to increase the dehumidification effect
When the winter cold starts, the fog of the front windshield is attached to the interior of the vehicle, the main reason is that the humidity inside the vehicle is too high, and the water vapor in the car is liquefied after cold, and a layer of hazy fog will be attached to the surface of the front windshield. The owner can reduce the humidity in the car, so as to suppress the liquefaction of the water vapor in the car as much as possible, and open the AC button of the air conditioner to remove the humidity in the car with the air conditioner, which is very significant for the defogging effect of the front windshield.
On cold start, the outer loop is turned on
On how to slow down the fog on the surface of the front windshield, you may have mastered the above two techniques, "one-click defogging and opening the AC button", but in the winter cold start, there is an additional skill, that is, to turn on the external circulation of the air conditioner, which can significantly improve the defogging effect under the cold start condition of the vehicle.
According to the above analysis, after the owner enters the car, the air temperature in the car increases, and the air with higher temperature encounters the low temperature of the front windshield, which will liquefy into fog, but if the owner opens the external circulation and opens the one-key defogging function, the outside air flows directly into the front windshield surface, which is conducive to preventing the air with higher temperatures from contacting the front windshield surface, and the fogging effect will be well suppressed.
Under normal circumstances, when the vehicle starts cold in winter, if the owner encounters a more serious fog in the front windshield, it can be effectively solved by the above three methods, but if the temperature is too low and the fog is too serious, the owner can also improve through the following methods.
Zoom in: Open the window
Why is opening the window effectively preventing "fog on the surface of the front windshield during cold start"? It is from the root to inhibit the generation of fog, the front windshield surface of the fog is due to the large temperature difference between the inside and outside of the car, the temperature inside the car is high, the temperature outside the car is low, resulting in fog inside the front windshield, but if the owner opens the window, the temperature inside and outside the vehicle will tend to be balanced, so that the fog can be suppressed on the root.
Of course, in addition to the above four methods, the owner can also idle the car, after the engine temperature rises, the air blown out of the air conditioner is hot air, and the steam on the surface of the front windshield can be quickly suppressed. However, the idle hot car is damaged to the engine, it is easy to increase the carbon deposit inside the engine, so it is generally not recommended that everyone take the "idle hot car" approach.
In summary, if the vehicle in the winter cold start, the front windshield appeared fog, affecting the normal driving of the owner, the owner needs to open the air conditioner, open a key defogging function, while opening the AC button, if the fog can not be effectively removed, the air conditioning air volume can be adjusted to the maximum, or directly open the window, through the above method, the fog on the surface of the front windshield will be effectively removed.
