Which air circulation mode should be used for defogging inside the car?
1 Answers
Using the air recirculation mode can defog the windshield faster. Here is a brief introduction to the recirculation and fresh air modes: 1. Recirculation mode: This mode is designed to prevent dust and odors from entering the car through the fresh air system by closing the external air intake duct, thereby blocking polluted outside air. 2. Fresh air mode: Since the car interior forms a relatively sealed environment, prolonged occupancy may lead to oxygen deprivation. Therefore, the air conditioning system includes an additional air duct to draw fresh air from outside, which then passes through the evaporator or heater core to deliver either cool or warm air.
