How to Turn on the Air Conditioning After the Car Has Been Exposed to the Sun?

After the car has been exposed to the sun, it is necessary to fully open the windows or doors to allow the harmful gases inside the car to completely dissipate, creating a relatively normal environment inside the vehicle. Only when the interior temperature has dropped is the best time to turn on the air recirculation mode. Here is some additional information: 1. External Circulation: In this mode, the fan draws air from outside the car into the interior, meaning there is a flow of air between the outside and inside of the car. The air blown by the fan comes from outside, and even if the fan is not turned on, air will still be drawn into the car while driving, replenishing the fresh air inside. Sometimes, you may feel air coming in even when the fan is off—this is because the external circulation mode is set. 2. Internal Circulation: In this mode, the airflow passage between the inside and outside of the car is closed. Without the fan, there is no airflow circulation, and when the fan is turned on, the air drawn in comes only from inside the car, creating an internal airflow cycle. The internal circulation mode is mainly used to effectively and promptly block external dust and harmful gases from entering the car, such as when driving through areas with smoke, dust, strong odors, or when driving in heavy traffic where harmful exhaust fumes from the car in front need to be blocked.
When I encounter a situation where the car interior becomes as hot as a steamer after being exposed to the sun, I usually open all four doors to ventilate for a minute or two to let the hot air escape. Then, I get into the car, start the engine, and immediately lower all the windows instead of turning on the air conditioning. I begin driving at a low speed for about 300-500 meters to allow air to circulate inside the car. Only then do I press the air conditioning button, set the temperature to around 26 degrees, and switch to the external circulation mode to speed up air exchange. After turning on the air conditioning, I continue driving with the windows down for a few more minutes until the air conditioner starts blowing cool air, then gradually close the windows. This method cools the car faster and prevents the compressor from being overloaded suddenly, protecting the air conditioning system. Finally, don’t forget to switch the air conditioning to internal circulation mode for longer-lasting cooling effects. The whole process takes about five to six minutes but is much more effective than turning on the air conditioning directly.
