What is the general temperature setting for car air conditioning?

Car air conditioning is generally set between 21 to 25 degrees Celsius in summer and 25 to 28 degrees Celsius in winter. The temperature difference between the interior and the external environment should not be too large, as it may cause discomfort to passengers. Car air conditioning refers to the air conditioning system installed in vehicles, capable of cooling, heating, ventilating, and purifying the air inside the cabin, providing a comfortable environment for passengers, reducing driver fatigue, and enhancing driving safety. The air conditioning system has become one of the indicators for assessing whether a car is fully equipped. It typically includes cooling, heating, and ventilation devices. This integrated system makes efficient use of the limited space inside the car, features a simple structure, and is easy to operate, representing the internationally popular modern car air conditioning system.
I've been driving for several years and am accustomed to setting the air conditioning between 22°C and 24°C, finding this temperature range the most comfortable. During hot summers when the outside temperature often exceeds 30°C, I initially set the AC to the lowest 16°C to cool the car quickly, then gradually adjust it back to 24°C to avoid excessive fuel consumption and engine strain due to large temperature differences. In winter, I set the car's heating system to around 25°C to maintain warmth without making the air too dry. Cars with automatic air conditioning are quite convenient as they can adjust the temperature based on both interior and exterior conditions, typically maintaining the optimal range of 20-25°C. I also regularly replace the cabin air filter to prevent dust accumulation, which could affect air quality and temperature uniformity. Overall, maintaining a stable temperature of 22-24°C is both fuel-efficient and healthy, and I've never encountered any issues using this approach over the years.
I drive a new car with automatic air conditioning, and the temperature setting is quite intelligent, usually set at 23 degrees. The system has sensors to monitor the temperature and humidity inside and outside the car, automatically adjusting the airflow and temperature, with a fully adjustable range from 16 to 30 degrees. Manual air conditioning requires manual control; in summer, I often use 22 degrees for cooling, and in winter, 25 degrees for heating. Setting the air conditioning too low, such as below 18 degrees, consumes more fuel, so I maintain a median balance for efficiency. Regular maintenance includes checking the refrigerant pressure, and if the temperature is inaccurate, it might indicate a refrigerant leak requiring repair. Solar heat films applied to the windows can also assist in cooling, making daily use truly hassle-free.
The most important thing for air conditioning temperature is health. I usually set it at 22 degrees to maintain comfort, avoiding being too cold and catching a cold or too hot and sweating. Keeping the temperature difference between inside and outside the car within 7 degrees is safer, for example, setting it at 28 degrees when it's 35 degrees outside is fine. When traveling with elderly or children, set the temperature slightly higher at 25 degrees to prevent catching a cold. In summer, open the windows to dissipate heat before closing them and turning on the air conditioning at 24 degrees for energy saving. Don't use the internal circulation mode for too long; switch to external circulation to ventilate and prevent stuffiness. The 22-24 degree range is the most balanced for the body's needs.
