Automobile skylight function. A fresh air, one or more "windows", naturally there is an additional vent, so opening the skylight will increase the airflow speed in the car. Especially when there are many people in the car, the ventilation holes in the skylight can improve the ventilation in the car. Because the skylight is based on the principle of negative pressure ventilation, when the car is driving, the airflow flows quickly on the roof, forming negative pressure in the car and pumping away the turbid air in the car. Because it is not directly inflated, it is ventilated by pumping dirty air from the air inlet and supplementing fresh air, so the airflow on the car is soft, and there will be no uncomfortable feeling that the wind does not directly blow on the body, dust is not involved, and wind noise is less.
Using skylight to defog is a fast defogging method. Especially in summer and autumn, there is much rain and large temperature difference. Drivers all know that if the side window of a car is closed tightly when driving, the temperature difference between the inside and outside of the car will increase, and the front windshield will easily form fog. Most cars are equipped with anti-fog devices, but some of them are not very effective. As long as the owner opens the skylight, he can quickly remove the fog on the front windshield to ensure driving safety.
In hot summer, if the car is exposed to the sun for an hour, the temperature inside the car will reach about 60. Many car owners will immediately turn on the air conditioner and choose to lower the temperature on the car. If your car has a skylight, you can open the skylight and use the negative pressure formed by the roof to pump out the hot air when the car is driving, thus reducing the temperature. Using this method can be two to three times faster than using air conditioning, and it can also reduce energy consumption.
In summer, especially the panoramic skylight, you can get more sunshine even if you play the awning, and the temperature is very high. It is easy to produce joints. Could be the assembly process. Many models may have sunroof joints. Once you win, you win the bid. Please repair it. It's all going to be torn down, but it hurts. Don't fix it. I'm tired of squeaking all day. (For example, KIA (brand) K5 Hyundai Sonata 8, Audi Q5, etc. It's all here Many people may have heard of this, but they can't help it. The skylight leaks and they are in a bad mood when driving a good car. Sometimes, it doesn't leak directly into the cockpit, but it is slightly wet along the partition, which looks even worse.
The overall stiffness of the car body decreases and the safety factor decreases. Which car body has higher rigidity and stability, a car without the same sunroof or a car without a panoramic sunroof? Which is stronger, the glass cover or the metal cover, especially in the case of strong collision or rollover? Falling from high altitude is not safe. There is a panoramic skylight car parked downstairs. Heavy objects falling on it will break the skylight and people inside the car will be injured. Generally, if a car drops a heavy object, the roof will hit a pit at most, and the car is definitely safe. Skylights tend to hide dust. I believe that everyone does not deny it. Dust needs to be cleaned up, otherwise it will affect your eyesight. The above is an introduction to the function of automobile sunroof, and the advantages and disadvantages of automobile sunroof. I hope it helps.
