Should the Car Air Conditioning Be Set to Recirculate Mode?

[JonathanMarie]

Generally, the recirculation mode is more commonly used when driving with the air conditioning on. Below are detailed explanations of the car's recirculation and fresh air modes: 1. Fresh Air Mode: This mode draws air from outside the vehicle, directs it through the air conditioning system for heating or cooling, and then blows it out through the vents. Essentially, the fresh air mode replenishes the cabin with fresh air, improving the air quality inside. It is particularly useful for defrosting in winter or defogging in summer, as the air drawn from outside is richer in oxygen and drier, making it more effective for these purposes. 2. Recirculation Mode: This mode recirculates the air inside the vehicle, creating an internal airflow cycle. Its primary function is to effectively block external dust and harmful gases from entering the cabin. It helps the car warm up faster in winter and cool down quicker when the air conditioning is on in summer. It is also beneficial to use during smoggy conditions. The recirculation mode maintains the cabin temperature more efficiently by recycling the interior air.
