How to quickly remove fog in the car on a rainy day? What should I do if there is fog on the glass i

In rainy days, fogging in the car is quickly eliminated, and it is operated according to two conditions. If it is in a cold winter, the fast defogging method is to turn on the air conditioning defogging function and adjust the air volume and temperature to the highest setting, adjust the circulation mode to the external circulation state, and turn on the windshield heating function at the same time if there is one; If it is in the hot summer, the rapid defogging method is to turn on the refrigeration function, the wind direction is directed to the windshield, the cycle mode is adjusted to the external circulation state, and the temperature is adjusted to the lowest and the air volume is adjusted to the maximum.

The use of hot air to remove fog must ensure that the body is comfortable under the premise. Previously, it was reported in the news that a car owner in Changsha, Hunan Province was driving a car on the highway, and later the traffic police found that the driver was unconscious in the emergency lane, due to the owner's low blood sugar and the high temperature of the air conditioner in the car, and the closed windows caused poor air and caused physical discomfort. I hope that car owners and friends must use the vehicle air conditioning equipment correctly.

If there is fog on the glass inside the car on a rainy day, you may not need the most extreme defogging method, you can use conventional defogging methods to avoid physical discomfort caused by too high or too low temperature in the car. Here's a general defogging operation:

Method 1: Spraying anti-fogging agents and other preventive methods. Spray a little defogging agent on the car glass window, and then wipe it clean to remove the dirt and stains on the glass window.

While polishing the glass, a thin layer of transparent protective film is formed on the glass, which can effectively prevent the fog layer formed by the condensation of water vapor on the glass, especially suitable for cold winters.

Method 2: Use the air conditioner refrigeration function to defog. Fogging of the windshield is usually caused by a large temperature difference between the inside and outside of the car, and there is a lot of moisture in the car.

At this time, you can turn on the air conditioner to blow cold air on the front windshield, and use the air conditioner's dehumidification function to remove the fog vapor on the front windshield slightly. However, if the humidity is too high and the effect of air conditioning is not obvious, you can open the windows a little to quickly reduce the humidity in the cab.

Method 3: Reduce the temperature difference and then remove the fog. Fogging is removed by reducing the temperature difference, and windshield fogging in cold or rainy and foggy seasons is often caused by the temperature difference between the inside and outside of the vehicle.

Use warm air to blow hot air on the glass, quickly increase the temperature of the front glass, reduce the temperature difference between the inner and outer surfaces of the window glass, and prevent the fog vapor of the front windshield from being too heavy in time. However, hot air defogging requires a high temperature and takes a long time, so it is recommended to stop the car and wait for the fog to be removed before driving.

1. Defogging with air conditioning system It is a common practice to use air conditioning to defog out. Turn on the cold air to blow the glass, and the defogging effect is very straightforward.

Second, the effect of hot air blowing fog with hot air blowing glass is better than that of cold air, but the effect is slower than that of air conditioning. When the hot air dries the moisture in the car, the glass will no longer fog up for a long time. It is best to turn on the hot air first when parked, and then pick up a rag and wipe it again.

In addition, opening the external circulation during driving can also prevent fogging to a certain extent.

3. If the fog is not big and the temperature outside the car is not very low, you can lower a part of the windows on both sides to let the air in the car convection, and the temperature in the car will slowly approach the temperature outside the car, and the fog will disperse.

Fourth, the method of detergent anti-fogging blending "anti-fogging agent" to prevent fogging has been well known to many people. The ratio of washing spirit to water is about 1:10, and then use absorbent cotton or a clean and soft cloth dipped in it to apply it to the inside of the front and rear windshields, and then wipe off the remaining watermarks left on the inside of the glass after drying. It will work better with an air conditioner.

Use air conditioning or warm air to defrost the front window, and the fog from the front windshield and the left and right front door glass can be removed. Pay attention to where to defrost with the front windshield.

Fogging is the reason why the internal and external temperatures are different, turn on the fan, turn on the warm air in winter, open the external circulation in summer, and adjust the air outlet before the window is OK, and it will be done in 5 seconds.

1.Buy a special car glass defogging spray, ** is available. Pros: Simple. Disadvantages: Higher fees.

2.Apply the same detergent used for car washing (do not dilute) directly to the inside of the car glass and polish it when it is completely dry. The effect is obvious.

Pros: Cheap, negligible fees. Cons:

The taste is unpleasant. It's going to take a long time for that thing to dry. The polishing process is a cup.

When washing a car, scrubbing the inside of the window is also a cup.

3.Turn on the air conditioner, but does it need to be said? If that's all there is to it, do you still ask?

Turn on the outer circulation, and turn on the air conditioner to blow the front gear, and there will be no problem.

We should have all had this situation, fogging on the glass inside the car on a rainy day, if there are passengers in the same car in this situation, it is easy to solve, let them help wipe it, if the driver drives alone, it will be more troublesome, so how to solve the fog in the car in the rain?

There are many ways to eliminate water mist in the car on rainy days, and it is necessary to pay attention to the fact that when removing fog, it is necessary to avoid the temperature in the car being too high or too low to cause discomfort to the body of the driver and passengers, and do not use too extreme defogging methods.

First of all, in order to prevent fogging in the car on rainy days, you can spray anti-fogging agents in advance. When spraying, you can spray a little, wipe it clean after spraying, and form a protective film for it while wiping the glass, which can effectively prevent the formation of mist by water vapor, this method is mainly suitable for rainy days in winter.

In the case of winter rain, there is to turn on the defogging function of the air conditioner in the car, and adjust the air volume and temperature to the highest gear, adjust to the external circulation, some models have the windshield heating function, you can also turn on the heating function, the hot air to eliminate the fog needs a higher temperature and takes a long time, at this time it is best to stop and wait for the fog to eliminate before going on the road.

The fog in the glass inside the car on rainy days is mainly due to the large temperature difference between the inside and outside of the car, coupled with the fact that there is more humidity in the car, which is mainly common in summer. In the case of rain in summer, you need to turn on the refrigeration function of the air conditioner, turn the wind direction to the windshield direction, adjust the circulation mode to the outer circulation, adjust the air volume to the maximum and adjust the temperature to the lowest. The vehicle's air conditioning equipment needs to be used correctly, and it is best to open the windows for ventilation at regular intervals.

If the humidity in the car is too large and the air conditioning effect is not obvious, you can open a little window to quickly reduce the humidity in the car and solve the fogging state.

1. Adjust the tuyere to the one that blows the front windshield, remember to open the external circulation, and blow the cold air. In this way, the temperature will drop very quickly, and the fog will naturally disappear.

2. You can install a rain shield, so that when it rains, you can open a little window, so that the air inside and outside the car can be effectively convection, and the temperature difference will be gone, and there will be no fogging.

3. You can also apply a layer of detergent in front of the window, which can also have the effect of anti-fogging. The method is simple: dilute the detergent and apply a gentle layer with a cloth. Try it and you'll find out, there are also ready-made ones on the market.

4. The fog on the side windows will also affect the driver's view of the rearview mirror. You can use cold air to blow, remember to adjust the wind direction, in addition to the left and right side of the air holes open, the middle air holes can be closed to strengthen the wind. Foggy rear windows can be heated with electricity.

The most convenient and fast way to defog the car in rainy days is to use the air conditioning system:

For manual air conditioning, turn on the front window defogging mode, then adjust the wind speed to the maximum, turn on the A C switch, and then adjust the temperature to the lowest, and the fog on the glass will disappear after a while.

Some models come with an electrically heated rear windshield and exterior mirrors that can be switched on for about a minute to remove fogging.

In the case of automatic air conditioning, you generally only need to press the one-button defrost button, and after pressing it, the air volume will automatically turn on to the maximum and open the external circulation, which is both practical and convenient.

We can also use the heating system to defog, if the car has just started, do not start the air conditioner for the time being, wait until the engine is warmed up for a few minutes, after the water temperature rises, then start heating, adjust the air volume to the maximum, and then also turn on the front window defogging mode, and the fog will disappear in a few minutes. This treatment is also suitable for fogging the outside of the glass in the summer.

There are many ways to remove fogging, and most people in Dongchang have a way to deal with fogging of the front windshield: turn on the air conditioner and blow on the glass. Blowing the front windshield with air conditioner actually forms an "air-conditioning film" on the surface of the glass to prevent hot air from condensing on the glass, so it can have a defogging effect.

But turning on the air conditioner on a cold day and getting cold yourself is not a long-term solution.

Another way is to open the window for convection, and the air inside the car will be convection, and the temperature inside the car will slowly approach the temperature outside the car, and the fog will dissipate. The advantage is that it can achieve the effect of turning on the air conditioner without increasing fuel consumption, but this method is not suitable for all situations, such as in the cold winter and when it rains. The above defogging methods are all palliative, not curative, and cannot completely solve the problem of fogging, and will also affect the people in the car.

To solve this problem, it is necessary to analyze the causes. The reason for the fogging of the car windows is "hot inside and cold outside". The temperature difference between the inside and outside of the car is 10 to 20 degrees Celsius, and the hot air exhaled by the occupants of the car will condense into water vapor when it encounters cold glass, which will condense on the windows.

This is an old problem, but it is not a small problem, because once the driving vision is blocked, it will not be clear in a few seconds.

The correct way to open: the first step is to stop (the vehicle in the line code must pull over) and turn on the heater. Because when the glass has been fogged up while driving, the fog on the glass will become more and more serious, and it will be more obvious when the moisture in the air is heavy in rainy days, and the front windshield will suddenly become ground glass, which is very dangerous!

Therefore, it is recommended that it is best not to try to blow the windshield with hot air while driving. It is best to blow the glass with hot air until it is dry before driving.

The second step is to increase the temperature of the warm air (the higher the better) and wait for 3-5 minutes. The process of using warm air to defog is relatively long, and when it is first opened, it will indeed make the fog on the inside of the glass larger, because the temperature difference between the inside and outside is greater, and after the hot air dries the moisture in the car, the glass will become transparent, and it will be good after a few minutes.

The third step is to wait until the fog on the inside of the glass is all blown dry to reduce the temperature, because the inside of the car is dry, the vehicle will not fog up again during driving, and it can be adjusted to a temperature that the human body feels comfortable with.
