Should the Air Conditioning Be Set to Recirculation or Fresh Air Mode?
1 Answers
Air conditioning should alternate between recirculation and fresh air modes. In summer, using recirculation mode helps cool the car interior quickly, blocks harmful external gases, and prevents outside air from entering the cabin. However, exhaust gases inside the car will still be expelled through the vents. At this point, switching to fresh air mode allows fresh air to enter the vehicle rapidly. The automotive air conditioning system, commonly referred to as car AC, is designed to regulate and control the temperature, humidity, air cleanliness, and airflow within the car cabin to optimal conditions. It provides passengers with a comfortable environment, reduces travel fatigue, creates favorable working conditions for the driver, and plays a crucial role in ensuring safe driving as an essential ventilation device.
