[China Glass Network] Before explaining the cause of windshield fogging, let us start with the concept of water vapor, relative humidity and dew point in the air. After all, this is the more basic reason for the formation of windshield fogging.
Under a given temperature environment, the pressure of the water vapor that the air can withstand is constant. The higher the temperature, the greater the pressure that the atmosphere can withstand the water vapor, and the less easily the water vapor reaches the saturated gas pressure. On the contrary, the more At lower temperatures, the easier it is for water vapor to reach saturation, the easier it is to form dew.
Relative humidity refers to the percentage of the actual water vapor density in the air and the saturated water vapor density at the same temperature. The relative humidity of the air is related to the degree of saturation of the water vapor contained in the air, and the moisture in the air. There is no direct relationship between the amount. When it reaches 100% relative humidity, we call it saturated. If we add more water, the air will be supersaturated to form water droplets.
With the rapid development of China's economy in recent years, a car is no longer an expectation for our people. According to statistics, in 2008, the sales volume of China's automobiles has exceeded 8.7 million. However, while China's auto industry is developing at a high speed, bringing convenience and joy to people, hidden dangers are also coming. In 2007, a total of 327,209 road traffic accidents occurred in China, causing 81,649 deaths, 380,442 injuries, and direct property losses of 1.2 billion yuan. This road accident rate far exceeds the average level of western developed countries, and the road above Among the causes of the accident, a considerable part of the accident occurred because in the winter or on rainy days, the driver's line of sight was blurred due to the fog on the windshield, which led to road accidents.
Today, there are many models with the “Defogging†button. For customers, directly using this defogging gear to defogg seems to be a very simple thing, but in fact many drivers are fundamentally I don't know when the car is fogging, I need to remove the fog, and when I don't need to remove the fog, I can turn off the button of the defogging gear. Customers often do not need to start the defogging function when it is not appropriate. Or when the car does not need to defogg, the driver continues to activate the defogging function, running the car's HVAC system for defogging, which greatly wastes energy consumption. At this time, an intelligent automatic defogging is needed. The system helps everyone determine the necessity and time of defogging. The automatic defogging system not only protects the life of people inside the compartment, but also saves the consumption of automobile energy, which plays an indelible role in saving fuel consumption.
In the past period of time, scholars and organizations from all over the world have done some research on windshield anti-fog. Windshield fogging is a phenomenon that often occurs easily. American professor JD proposed to solve the problem of "windshield fogging" is the second largest criterion for judging the quality of modern automobile HVAC system.
Scholar Allison research, consumers are quite interested in the "smart automatic anti-fog system", and the survey shows that most consumers in the anti-fog system need to increase the corresponding cost of $75 is acceptable, intelligent automatic anti-fog system and Engine control and wireless monitoring of car wheels have become the three major topics of interest to today's consumers.
