Using Recirculation or Fresh Air Mode in Winter?
1 Answers
Whether to use recirculation or fresh air mode in winter depends on the situation: use recirculation mode for short trips and fresh air mode for long-distance driving. The two modes refer to: 1. Recirculation mode means the air conditioning system closes external air intake and only circulates the air inside the vehicle cabin; 2. Fresh air mode means the air conditioning system opens external air intake to circulate outside air. The functions of automotive air conditioning are: 1. To cool, heat, ventilate and purify the air inside the vehicle; 2. To provide a comfortable environment for passengers, reduce driver fatigue and improve driving safety.
