When buying a car, should I buy a car with or without a sunroof? Let’s talk about the pros and cons!

Advantages of sunroof

1. Rapid heat dissipation

When the car is exposed to the sun for 1 hour, the temperature inside the car will be about 60℃. Many car owners immediately choose to use air conditioners in their cars to reduce the temperature inside the car. If your car has a sunroof, you can use the negative pressure created by the roof of the car while driving to discharge hot, dry air by simply opening the sunroof. This method cools down 2 to 3 times faster than using an air conditioner, and fuel costs are also reduced.

2. High-speed ventilation

The skylight is very useful for people who often smoke in the car. When the vehicle is driving at high speed and the windows are opened, the vehicle speed is very fast, the wind can easily blow away the items in the vehicle, and the noise will be loud. At this time, open the sunroof. According to the principle of negative pressure when the car is driving, the difference in air pressure between the inside and outside of the car will lead to smoke in the car, achieving the purpose of ventilation, which is much lower than the wind noise when opening the side windows.

3. Traffic jams and prevention of exhaust gas

Traffic jams in cities are very common. When people are stuck in traffic jams, car exhaust is emitted into the air. At this time, we open the car sunroof and close the side windows. At this time, the dirty air in the car is discharged through the skylight, and the clean air filtered by the air conditioner enters the car. This can prevent exhaust gas from entering the car when the traffic jam begins.

Disadvantages of sunroofs

1. The most obvious one is the economic problem. Equipping sunroofs will definitely increase the cost. Of course, consumers need to spend more money, so consumers should pay attention to the problem before buying a car. Economic factors must be taken into account.

2. Secondly, abnormal noise is likely to occur. It may be a problem with the assembly process. Abnormal noises from the sunroof occur in most models. Repair it, you have to take it all apart, it hurts! If it is not repaired, it will creak all day long, which is annoying!

3. The most terrifying thing is that the skylight leaks. Sometimes it does not leak directly into the cab, but a little bit of dampness along the partition, as if it is in a water curtain hole, which is absolutely disgusting.

The ventilation principle of the sunroof

The ventilation of the sunroof uses the negative pressure principle, that is, it relies on the airflow in the car during driving. The rapid flow at the top of the sunroof creates negative pressure in the car and exhausts the air inside the car.

When the sunroof is opened, the air in the car is first extracted instead of directly entering the air. After the dirty gas is extracted, filtered fresh air is replenished from the air inlet.

Opening the sunroof for ventilation also has a much smaller impact on the air conditioning in the car than opening the side windows. Adopting this ventilation method of exhausting air first and then inhaling air can speed up the air renewal speed and have little impact on the air conditioner.
