Sunroof is no longer a "patent" of luxury cars, and now many economy sedans are also equipped with sunroofs. In actual use, the sunroof usage rate is not high and has become an unnecessary configuration. In fact, a small skylight has many uses.

1. Quickly eliminate the fog inside the car

Using the sunroof for defogging is a quick and effective method. Especially in summer and autumn, there is a lot of rain and high humidity.

Drivers know that if the side windows of the car are tightly closed during driving, it will increase the temperature difference between the inside and outside of the car, and the front windshield is prone to fogging up.

Although most cars are equipped with anti fog devices, some of them are not as effective. Drivers only need to open the sunroof to the rear ventilation position, which can easily eliminate the fog on the front windshield and ensure driving safety.

By using the sunroof for ventilation, you don't have to worry about the harsh and dirty environment outside the car, nor do you have to worry about rainwater being blown into the car.

2. Rapid cooling saves energy

The use of skylights also has energy-saving effects. In hot summer, if a car is exposed to the sun for an hour, the temperature inside the car can easily reach around 70 ℃. Open the car door, and a wave of heat will hit you. For many people, they choose to immediately turn on the air conditioning in the car to lower the temperature inside.

In fact, if you own a sunroof version of a car, simply open the sunroof and use the negative pressure formed on the roof of the vehicle to extract hot air during driving to achieve rapid ventilation and cooling. This method is 2-3 times faster than using car air conditioning to cool down, and also saves gasoline.

3. The best time to open the sunroof

In early spring, the early morning and evening are still chilly, which can easily make one fall for the trick. At this point, in order to ventilate without losing the temperature inside the car, we need to open the car sunroof.

Because the car sunroof is installed on the top of the car, its negative pressure principle will extract a large amount of waste and turbid gas that is trapped on top, forming a gas exchange with the turned on hot air conditioning. This not only does not lose the temperature inside the car, but also achieves good ventilation effect, which is a win-win situation.

4. Cars that have been exposed to direct sunlight

After your car has been exposed to the sun, you can open the sunroof. The best way to ventilate the car is to combine air conditioning and a sunroof.

Experimental results have shown that the most ideal way to achieve a balanced temperature inside a car is to open the air conditioning and sunroof. After being exposed to sunlight, the car is like a stranded whale, requiring a quick and gentle temperature adjustment method to lower the temperature. In this situation, opening the sunroof and air conditioning inside the car is the best choice, energy-saving and fast!

5. Cars in traffic jams

When stuck in traffic, all vehicles are in a stagnant or slow-moving state, and car exhaust will inevitably be denser than ever before. At this point, opening the car sunroof and closing all side windows can prevent you from worrying about exhaust fumes entering the car. The negative pressure ventilation of the car sunroof will exhaust the exhaust gas inside the car, preventing polluted air from entering the car.
