Should You Use Recirculation or Fresh Air Mode for Car AC in Summer?
2 Answers
In summer, it is recommended to use the recirculation mode for your car's air conditioning. This helps reuse the cooled air, reduces cooling energy consumption, and consequently lowers the engine's fuel consumption. However, remember to open windows periodically for ventilation to prevent discomfort caused by stagnant air. Here are relevant details: Recirculation Mode: This mode closes the external air intake and circulates only the air inside the vehicle cabin. Fresh Air Mode: This mode opens the external air intake to draw in outside air for circulation. Car air conditioning refers to the climate control system installed in vehicles, capable of cooling, heating, ventilating, and purifying cabin air to provide a comfortable environment for passengers, reduce driver fatigue, and enhance driving safety.
I've been driving for many years, and in summer, I immediately turn on the air conditioning's recirculation mode as soon as I get in the car. This quickly cools down the interior temperature by utilizing the existing cool air circulation, making it comfortable within minutes. However, prolonged use of recirculation can make the air stuffy, leading to dizziness and discomfort. I usually switch to fresh air mode after 15-20 minutes to introduce outside air and prevent oxygen deprivation. This is especially important during highway traffic jams—poor air quality can cause distraction and affect safe driving. I also keep a small air quality monitor in the car to track changes and ensure comfort and safety. In short, start with recirculation for rapid cooling, then switch to fresh air mode at the right time to maintain a cool and fresh environment.
