The reason for the fogging of the windshield is actually very simple. It is due to the temperature difference between the inside and outside of the car. It acts on the windshield, and the temperature in the cab is higher than the outdoor, causing the condensation in the cab to form fog on the inner windshield.
This phenomenon is more common in winter. The fog on the windshield believes that all drivers have encountered many people who are used to it or turn a blind eye to the poor treatment will seriously affect the driving, and even lead to a car accident.
Here are some solutions for windshield fogging, hoping to help you quickly defogg or fundamentally avoid fogging of the glass.
Simpler solution to windshield fogging - driving windows to circulate air inside and outside the car
The fogging of the windows is caused by the temperature difference between the inside and the outside. Can the temperature difference be solved?
The answer is yes. Ventilation of the window allows the convection of the interior and exterior of the vehicle to alleviate the fogging of the glass.
The advantage of this method is to alleviate the fogging of the window without any tools, but this method can not be used in all situations, such as when it is raining.
If the fog is not big, we can open a gap between the windows on both sides (it can't be done when it rains), so the air inside the car will convect, the temperature inside the car will slowly approach the temperature outside the car, and the fog will Scattered. The advantage is that it can achieve the effect of air-conditioning and does not increase fuel consumption, but this method can not be used in all situations, such as cold winter and rain.
More practical solution to windshield fogging - using the car's own air conditioning system to blow
Winter and rainy days are the high incidence of foggy windows. I believe many car owners will use the car's own air conditioner to defogg, but the debate on the topic of using cold air or warm air to remove fog is not stopped. In fact, this issue is two-sided and is discussed in different situations.
The usual practice is to turn on the fan and the cooling switch inside the car, so that the cold air will blow to the glass and the fog will be exhausted, and the effect will be very direct. This is because cold air is blown onto the glass to form a "cold film" on the surface of the glass, preventing carbon dioxide from agglomerating on the glass and providing a defogging effect. This method has a big drawback, that is, people in the car may feel very cold. Imagine that in the rainy days and winters where fog is prone to occur, the taste of blowing air in the car is really uncomfortable! Blowing for a few minutes may turn off the air-conditioning, and soon the fog will start to hang on the glass, and then open the air-conditioning... This is an inconvenient operation and the temperature inside the car will be very unsuitable, and the low-head operation will cause safety. There must be hidden dangers. Of course, if you are physically strong or have just undergone intense exercise, this method can also be used.
Solve the windshield fog problem or prevent it better
Method of avoiding fogging of windows
Method 1: Spraying anti-fogging agent and other preventive methods.
Spray a small amount of defogging agent on the glass window of the car and wipe it off to remove dirt and marks on the glass window. While polishing the glass, a thin transparent protective film is formed on the glass, which can effectively prevent the formation of a mist layer formed by condensation of water vapor on the glass, and is particularly suitable for cold winters. Can replace anti-fogging agent and detergent, soapy water, glycerin, alcohol or salt water, wait for it to dry, then wipe the excess fiber with suede or soft dry cloth, it can guarantee the car glass will not be covered within a few days Foggy.
Method 2: Air conditioning refrigeration method.
The air conditioning refrigeration dehumidification function is used to reduce the humidity of the air to remove the mist. When many people enter the car in the summer, the air conditioner is not turned on in time, and the humidity of the gas exhaled by the person is large, and soon the windshield will fog. At this time, the air conditioner can be turned on to blow the cold air to the front windshield, and the air conditioning dehumidification function can be used to remove the mist on the front windshield. However, if the humidity is too large and the air conditioning effect is not obvious, you can open a little window slightly to make it reduce the humidity in the cab quickly. Of course, it can also be used with air conditioners, and the effect will be faster.
Method three: air conditioning warm air method.
The fogging is removed by reducing the temperature difference. In winter, the hot air is blown onto the glass to quickly increase the temperature of the front glass, and the temperature difference between the inner and outer surfaces of the window glass can be reduced, so that the fogging of the front windshield can be prevented in time, but the temperature of the glass on the back and sides is increased. It is slow, so it takes a long time to remove all the fog. Note: Whether it is automatic or manual air conditioning, the air conditioner is turned on, which is good for dehumidification; the air conditioner temperature control should not be in a cold position, otherwise the outside of the defrosting windshield glass will be easy to fog.
