Treatment methods of road arch fog in rainy days.

Summer is coming, summer vacation is approaching, and more and more riders travel by car, but summer is the rainy season and the wettest time. So, how to solve the fog in the car?

The most important thing is that the weather is hot, so you should always turn on the air conditioner when driving, unless you go to Hulunbeier grassland, it is most comfortable to open the window.

The fog on the front window of the car is a very dangerous thing, which will hinder the line of sight and need to be dealt with frequently, affecting the pleasant mood and safety of traveling on the road.

Especially when it rains, cars are most prone to fog.

If the air conditioner is turned on for a long time, there will be fog outside the car, and the problem is very serious, which will cause wiper resistance and uncleanness.

There are two kinds of fogging on the front window:

One is that the humidity is too high, and the other is that the temperature is too low. Both are indispensable.

First, when the air humidity is constant and the window temperature is lower than the dew point temperature, condensation will form on the window surface, which is what we often see, the front windshield fogging.

Second, there is a certain temperature difference between the two sides of the window. When the saturated vapor pressure of surface moisture at lower temperature is lower than the surrounding environment, water vapor will gather on the glass surface and dialyze out in the form of tiny water droplets to form fog vapor.

Fog will form when the dew point temperature is higher than zero degrees Celsius, and frost will form when the dew point temperature is lower than zero degrees Celsius.

So, is there any way to defog quickly?

First: spray antifogging agent and other preventive methods.

Spray a little defogging agent on the window, then wipe it clean to remove dirt and spots on the window. When polishing glass, forming a thin transparent protective film on the glass can effectively prevent the fog layer formed by water vapor condensation on the glass, especially in cold winter.

Other anti-fogging agents that can be replaced are detergent, soapy water, glycerin, alcohol or salt water. After drying, use suede or soft dry cloth to wipe off the excess fiber, which can ensure that the automobile glass will not fog in a few days.

Second: open the skylight, or open the window to let the air convection.

Drivers with skylights can open the skylights to allow air convection, because the skylights can strongly absorb the polluted air in the car and can play a very good defogging effect.

If it is found that the fog in the car is not big, you can open a gap in the windows on both sides, so that the convection temperature difference between the air inside and outside the car will be reduced and the fog will slowly disappear.

The principle of this method is the same as that of turning on the air conditioner, but it does not increase fuel consumption. The disadvantage of window convection is very obvious, which is not available in rainy and snowy weather, expressway and foggy weather. Opening the window will reduce the temperature inside the car.

This method is not suitable for rainy days. No matter whether you open the skylight or open the window, raindrops will enter the car, which is not good.

Third: air conditioning refrigeration method.

Using the refrigeration and dehumidification function of air conditioner, fog and steam can be removed by reducing air humidity.

In summer, especially after many people enter the car, if they don't turn on the air conditioner in time, the gas exhaled by people will be wet, and soon the front windshield will be foggy. At this time, you can turn on the air conditioner and blow cold air against the front windshield, and use the dehumidification function of the air conditioner to slightly remove the fog and steam on the front windshield.

However, if the humidity is too high and the air conditioning effect is not obvious, you can open the window a little and quickly reduce the humidity in the cab.

Can be used with air conditioning, the effect will be faster.

Fourth: air conditioning and warm air method.

Eliminate fogging by reducing the temperature difference. Blowing hot air against the glass in winter can 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 front windshield from fogging too much in time.

The temperature of the glass on the back and side rises slowly, so it takes a long time to eliminate all the fog.

When it rains in summer, it is most likely to fog. At this time, when the air conditioner is turned on, the best defogging method has shortcomings, that is, the outside of the windshield is prone to fogging for a long time. Whether it is an automatic air conditioner or a manual air conditioner, turning on the air conditioner is beneficial to dehumidification.
