It's too hot. The car stopped in the sun. Do you want to open the window a little?

It is best to open the glass to avoid gas expansion in the car and the internal temperature is too high. After parking, the owner can leave a gap of 1~2 cm for each of the four windows to facilitate air circulation. When you open it again, the car won't be as hot as when you close it normally.

Exposure of cars to the sun will have the following effects:

First, the formaldehyde content in the air inside the car soared.

After the car is exposed to high temperature in summer, it will stimulate the release of pollution from many pollution sources, which is more likely to cause cancer over time. Formaldehyde is a colorless gas with a strong pungent smell, which is very harmful to human body.

Second, vehicles are aging.

Accelerate the aging of car paint and interior plastics; Ultraviolet rays will accelerate the aging of plastic parts and rubber parts (tires, etc.). ) and painting. The car has been exposed to the sun for a long time, and it smells pungent as soon as it opens the door.

Precautions for car use:

1. Try to choose a cool place to park. ?

The owner tries to find a cool place to park; Before getting on the bus, open the door and ventilate for 5 minutes, until the hot air and toxic gas in the car are exhausted (the owner can feel the same temperature as the outdoor temperature when entering the car), then close the window and turn on the air conditioner. ?

Don't turn on the air conditioner before entering the car. First, open the external circulation, adjust the air volume to the maximum position, and open all windows and skylights at the same time to achieve the purpose of rapid cooling. After this situation lasts for a few minutes, the temperature in the car will soon drop to a level that the human body can bear, and the driver can consider entering the car for long-distance driving. ?

When driving, the air outside the car circulates at a high speed, and the air pressure is low, and the hot air inside the car will be quickly dissipated, thus achieving the purpose of rapid cooling. Then you can close the windows and skylights, adjust the reasonable air volume, or open the internal circulation to enter the normal air conditioning use state.
