Which button to press to exhaust air from the car?
1 Answers
There are two circulation modes for exhausting air from the car: external circulation and internal circulation. Here are the extended details: 1. External circulation function: When using external circulation, fresh air enters the car from the external air intake, while the air inside the car is expelled through the vents at the rear of the vehicle, balancing the air pressure inside and maintaining air circulation. These vents are designed as one-way valves, allowing air to flow only from the inside to the outside. 2. Internal circulation function: The main purpose of the car's internal circulation is to block out polluted air, preventing external gases from entering the car, ensuring clean air inside without air flow circulation.
