What is the difference between the internal and external air circulation modes in Tesla's air conditioning system?
2 Answers
Tesla's air conditioning system has two air circulation modes: internal and external. The differences between them are: 1. Different states: In the internal circulation mode, the airflow channel between the inside and outside of the car is closed, and there is no air circulation without the fan; In the external circulation mode, the fan draws air from outside the car into the interior. 2. Different functions: The internal circulation mode mainly prevents external dust and harmful gases from entering the car in a timely and effective manner; The external circulation mode allows you to breathe fresh air from outside the car. 3. Different usage scenarios: When driving in the city, especially during rush hour traffic jams or in tunnels, it is recommended to use the internal circulation mode; When driving on highways, the external circulation mode should be used.
I think understanding the difference between recirculation and fresh air modes is crucial when using the air conditioning in a Tesla. Recirculation mode closes the windows and only circulates the air inside the car, essentially breathing the same air you exhale. This is particularly useful in summer to cool down the cabin quickly, or when passing through tunnels or areas with poor air quality, as it keeps pollutants out. However, prolonged use can make the air feel stuffy and stale. Fresh air mode, on the other hand, opens a vent at the front of the car to draw in outside air, which is then purified through a high-efficiency particulate air (HEPA) filter before being blown into the cabin. Tesla's 'Bioweapon Defense Mode' essentially maximizes the fresh air mode's power, ensuring clean air regardless of how polluted the outside air is. So, in general, use recirculation mode when stuck in traffic, passing through tunnels, or when you first get in the car to cool it down quickly. On highways or when the cabin feels stuffy after prolonged use, switch to fresh air mode or auto mode to improve air circulation.
