What should be the maximum temperature setting for a car air conditioner?

The most comfortable air conditioning temperature for the human body is between 24-27 degrees Celsius. Below is relevant information regarding car temperature settings: 1. For high interior temperatures, start with external air circulation: Cars parked under the scorching sun in summer can reach interior temperatures of 60-70 degrees Celsius. In such cases, first open the doors and windows to allow hot air to escape for two to three minutes before entering and starting the car. Do not immediately close the windows; instead, turn on the external air circulation first. Once the interior and exterior temperatures are similar, close the windows and switch to internal circulation. Although this may feel hot initially, it prevents excessive load on the engine during startup and allows the air conditioning compressor to quickly reach optimal working conditions, making it the best approach. 2. Direct cold air vents upward: The direction of the air vents is also important. When using the air conditioner, point the vents upward because cold air naturally sinks. Additionally, avoid setting the temperature too low or the fan speed too slow. For non-thermostatic air conditioners, initially set the temperature to the lowest and the fan speed to the highest. Once you feel cold, slightly increase the temperature and reduce the fan speed by one level. If you still feel cold, adjust the temperature higher and lower the fan speed further. Repeating this process is the correct way to operate the system.
As an experienced driver for many years, I believe car air conditioning temperature shouldn't be set too high. The most suitable range is 22 to 25 degrees Celsius, preferably not exceeding 24 degrees. Setting it too high makes the vent temperature high, the car interior not cool enough, and you may sweat and feel drowsy while driving, affecting safety. I always keep it fixed around 24 degrees because this temperature is both comfortable and won't cause excessive body temperature differences that lead to colds. In summer, I first turn on the AC at 20 degrees for quick cooling, then raise it back to 24 degrees to maintain balance. Also, pay attention to using recirculation mode, which makes the AC more efficient, saves fuel, and prevents outdoor odors from affecting health. Regular inspection of the cabin air filter is also important - if clogged, it affects temperature control. In short, keeping it within 24 degrees ensures both you and your car stay comfortable.
