What is the appropriate temperature for car air conditioning in winter?

In winter, an air conditioning temperature of around 20 degrees Celsius is suitable. The method to turn on the warm air is: 1. After starting the car, wait for the water temperature to rise to the normal level, then turn on the warm air switch; 2. Set the air circulation mode to internal circulation; 3. Adjust the air conditioning level to a suitable position and set the airflow direction. The functions of car air conditioning are: 1. To regulate the temperature, humidity, airflow direction, and speed inside the car, and improve air quality through the filter; 2. To provide a comfortable environment for passengers, reducing travel fatigue; 3. To create good working conditions for the driver, ensuring safe driving.
In winter, I usually set the car air conditioning to around 22°C. After years of driving, I find this temperature the most comfortable—neither too hot nor too cold. When starting the car, I wait a few minutes for the engine to warm up before turning on the AC to avoid discomfort from cold air blowing directly. Setting it to 22°C in heating mode with the AUTO function automatically adjusts the fan speed, saving the hassle of manual adjustments. I also turn on the external circulation to let fresh air in, preventing the cabin from getting too dry or the windows from fogging up. If fogging occurs, pressing the defog button clears it up in seconds. For short trips, I sometimes set it to 20°C for quick warming, while on long drives, maintaining 22°C ensures stability and prevents fatigue from temperature fluctuations. Safety-wise, too high a temperature can cause drowsiness, while too low can stiffen hands and feet—22°C is just right, balancing fuel efficiency and safety. Personally, I recommend using a small thermometer to monitor and ensure accuracy.
