The small cold has passed. The temperature in Beijing has dropped sharply. The severe cold has brought a lot of inconvenience to people with cars. Especially in the morning, a layer of frost is often formed on the outside of the windshield, and the inside of the glass will be covered with a layer of fog when the car is driven. Although this is not a big trouble, it may affect driving safety if it is not handled well. What are the tricks for defogging?
Answer: When the temperature is relatively low in winter, the car owner will close all the windows when driving, and there will be a layer of fog on the windows after a while. This is because the car glass is in contact with the outside, and its temperature is relatively low, and the temperature inside the car is relatively high. After the water vapor in the air contacts the car window glass with a lower temperature, a layer of mist is formed on the inside. If it is not removed in time, it will block the driver's sight and bring danger to driving.
Traditional method: In the process of driving, one of the most common methods used by many car owners is to wipe the fog on the windshield with a rag while driving to keep their sight clear. But one can't do two things with one heart.
If the owner of the car is driving the car by himself, using this method to defog, while driving and wiping the fog, the attention will definitely be distracted. If you can't focus on the road conditions, driving safety is difficult to guarantee. If the car owner is a novice, the risk factor is even greater.
There is a simple and convenient method suitable for young people. The formation of fog in the car is mainly caused by the high humidity in the car and the large temperature difference between the inside and outside of the car. So just open the window slightly to let the air flow. Eliminate the temperature difference between inside and outside, and the mist can be dispersed after a period of time. However, although this method is convenient and easy to use, the cold sunroof is a "test" for drivers and passengers. It is recommended that car owners exercise their bodies before using this method.

In this way, a transparent protective film is formed on the glass, which can effectively prevent water vapor from condensing on the glass to form a fog layer. Generally, one spray can prevent fog for about 5 to 7 days.

One of them is to adjust the air-conditioning vent to the windshield position, and turn on the air-conditioning to cool down.switch,letcompressorWork in order to dehumidify. However, at this time, the temperature knob must be placed in the warm air position to achieve both defogging and heating purposes; if the temperature control knob is adjusted to the cold windshield, the drivers and passengers in the car will be overwhelmed.
