What is the function of a car sunroof?

[LaMarcus]

The function of a car sunroof: Enhances the ventilation inside the vehicle, allowing for rapid cooling and better air renewal. It utilizes the superior principle of negative pressure ventilation to filter the air inside the car, thereby protecting the health of the driver and passengers. Car sunroofs can be broadly categorized into: sliding-out type, built-in type, built-in flip-up type, panoramic type, and curtain type. The car sunroof changes the traditional form of ventilation; when wind blows in, it creates an airflow that draws out the stale air inside the car. When the car is moving at high speed, air flows rapidly around the vehicle. Opening the sunroof creates a negative pressure zone outside the car, and due to the difference in air pressure inside and outside the car, the stale air inside is drawn out, achieving the purpose of ventilation.
