What Circulation Mode Should You Use in Your Car During Summer?
2 Answers
In summer, use the car's internal circulation mode. Below is an introduction to the internal circulation mode: Air Conditioning System: Internal circulation is a state of the car's air conditioning system. In this mode, the air exchange channels between the inside and outside of the car are closed. When the fan is off, the airflow inside the car does not circulate. When the fan is on, the airflow drawn in comes solely from inside the car, creating an internal airflow cycle. Function of Internal Circulation: The primary purpose of internal circulation is to effectively prevent external dust and harmful gases from entering the car. For example, when driving through areas with smoke, dust, unpleasant odors, or in heavy traffic, it blocks harmful exhaust emissions from vehicles ahead. Internal circulation enhances the cooling and heating efficiency of the air conditioning system and provides better insulation.
In summer, I often set the car air conditioning to recirculation mode because the outside temperature is too high. Using recirculation allows the cool air inside the car to circulate quickly without repeatedly cooling the incoming hot air, making it cool down fast and saving a lot of fuel. I remember once at noon when it was 35°C, I turned on recirculation as soon as I got in the car, and within less than ten minutes, the interior went from being hot and stuffy to refreshingly cool and comfortable. However, keeping recirculation on for too long can make the air inside the car stale and stuffy, so once the temperature drops, I usually switch to fresh air mode to let in some fresh air. Especially on highways, using fresh air mode can help prevent fatigue and is beneficial for health. If you notice any unpleasant odors outside, switching to fresh air mode promptly can help avoid pollution, which is quite convenient. Additionally, during the rainy season, using recirculation mode also prevents moisture from rain from entering the car. In short, recirculation is the go-to mode in summer, but flexible switching between modes ensures both safety and comfort.
