Should You Use Recirculation or Fresh Air Mode on the Highway?

[DelRemington]

Whether to use recirculation or fresh air mode on the highway depends on different situations: In summer, to quickly cool down and maintain the interior temperature, recirculation mode should be used; If there are many passengers in the car, it is necessary to periodically switch to fresh air mode to maintain air freshness. The definitions of recirculation and fresh air modes are: 1. Recirculation mode means the air conditioning system closes external air intake and only circulates the air inside the vehicle; 2. Fresh air mode means the air conditioning system opens external air intake to circulate outside air. The functions of car 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.
