Which is More Fuel-Efficient: Recirculation or Fresh Air Mode?
1 Answers
From a theoretical perspective, the recirculation mode is more fuel-efficient than the fresh air mode, but in practical use, the difference is negligible. The differences between car recirculation and fresh air modes are as follows: 1. Different air circulation methods: Recirculation mode circulates the air inside the car when it is closed; fresh air mode brings outside air into the car. 2. Different air circulation states: In recirculation mode, the air inside the car is heated or cooled before being sent back into the car; in fresh air mode, outside air is heated or cooled before being introduced into the car. 3. Different working principles: The recirculation mode works by promoting air circulation inside the car. The fresh air mode works by using a fan to bring outside air into the car, while the air inside the car is blown out through the fan, achieving ventilation without opening the windows.
