To prevent the damage of car exhaust, the internal circulation of the air conditioner used for driving is more effective

Word:[Big][Middle][Small] QR Code 2021/3/18     Viewed:    

For car owners, driving in the hot summer is a painful thing. Turning on the "internal loop" mode of the car can help you a lot.

The fan in the car is turned on, and there are two modes of external circulation and internal circulation. The external circulation is to use the fan to draw the air outside the car into the car, and the air inside and outside the car is circulated. The internal circulation is the air circulation inside the car. Using internal circulation in summer is equivalent to re-cooling the indoor cold air, which effectively improves the air conditioning effect.

More importantly, when you are in the constant flow of traffic, car exhaust will erode your health unknowingly, especially in a sultry sauna. The internal circulation can effectively stop these harmful gases in time. Scientific analysis shows that car exhaust contains hundreds of different compounds, including pollutants such as carbon monoxide, carbon dioxide, and hydrocarbons, which enter the human lungs with the breath, causing respiratory diseases and, in serious cases, lung cancer. Professor Wang Changli, director of the Department of Pulmonary Oncology, Tianjin Cancer Hospital, introduced that not only smoking, occupation, living habits, environmental pollution, etc., many factors may cause lung cancer, and the incidence of people who are exposed to car exhaust or often in polluted environments is higher. .

Therefore, the car mainly adjusts the internal circulation system in time according to the air condition outside the car. When encountering a traffic jam or following a vehicle with excessive exhaust emissions, it should be adjusted to the internal circulation mode. However, using the internal circulation mode for a long time can make people feel dizzy. When you feel unwell, it is best to use the external circulation for a few minutes to let fresh air into the car and improve the air quality.
