What is the appropriate temperature setting for a car's air conditioning?

The car's air conditioning in summer should be set to around 21°C to 25°C; in winter, it should be set to around 25°C to 28°C. Below is relevant content introduction: 1. Car air conditioning: Car air conditioning is a device that cools, heats, ventilates, and purifies the air inside the vehicle cabin. It provides a comfortable environment for passengers, reduces driver fatigue, and enhances driving safety. 2. Reasons for odors in car air conditioning: (1) When the air conditioning system operates, moisture in the air forms condensation on the surface of the air conditioning's condenser and evaporator, creating a breeding ground for mold, aspergillus, penicillium, and mites in the damp and dark air conditioning system. (2) Nicotine produced by passengers smoking in the car.
When driving long distances, I usually set the air conditioning temperature between 23 and 24 degrees Celsius, which is neither too cold nor too hot, providing a very comfortable environment. In summer, when it's hot outside, setting the temperature too low, such as 18 degrees, may make the car cool but increases the risk of catching a cold or feeling dizzy when getting out of the car. In winter, setting it to 25 degrees is sufficient; any higher can make the air too dry and uncomfortable. Actual adjustments depend on personal preferences: those who are sensitive to cold may set it higher, while those who tolerate heat well may set it lower. Automatic air conditioning is very convenient as it controls the fan speed and mode based on the set temperature, eliminating the need for frequent manual adjustments. When humidity is high, the air conditioning can dehumidify, and using the recirculation mode can improve efficiency. For long-term use of air conditioning, it's important to regularly clean the filter to prevent odors. Overall, setting the temperature should balance comfort, health, and driving focus, as extremes in temperature can be distracting. I recommend testing between 22 and 26 degrees to find the most comfortable setting for yourself.
