Automobile skylight function
Automobile air pollution seriously affects the health of drivers and passengers, especially after the car is sealed for a period of time, the car compartment is filled with harmful substances such as benzene and formaldehyde in decorative products. Therefore, the first thing to do when getting on the bus at night is to open the skylight of the car and use its superior negative pressure ventilation principle to filter the air inside the car to protect the health of drivers and passengers.
Matters needing attention
Open the skylight in case of traffic jam to prevent exhaust gas from entering the car. When there is a traffic jam, open the skylight of the car. Because all vehicles are in a static state during traffic jams, automobile exhaust will inevitably spread in the air. At this time, the sunroof of the car is opened and the side window is closed, so that the exhaust gas in the car is discharged and filtered by the car air conditioner to complete the exchange of fresh air.
Open the skylight to balance the temperature inside the car after exposure. In hot summer, the temperature inside the car will become very high after being exposed to the sun. At this time, waiting for the bus mainly opens the skylight in time. Experiments show that the most ideal way to realize the temperature balance in the car is to open the air conditioner and the skylight of the car, and the ideal oxygen supply will ensure the comfort and safety of the drivers and passengers.
High-speed skylight opening can reduce wind noise. When the car owner is driving at high speed, he is often troubled by the noise generated when the side window is opened and the crosswind blowing head-on. If you open the skylight and close the side window at this time, this situation can be effectively prevented. Especially when the vehicle speed reaches 100 km/h, the noise generated by opening the side window ventilation can be as high as 1 10 dB, while the noise generated by opening the sunroof of the car is only 69 dB. Secondly, the airflow flows rapidly at the top of the skylight, thus forming a negative pressure in the car and pumping away the dirty air. The application of this principle solves the problem of crosswind blowing head-on. From this point of view, it is particularly important to open the skylight for ventilation at high speed.
