What should the temp be set to in a car?

The temp setting in a car does not have a fixed optimal value; it should be adjusted according to the external temperature while driving. The temp in a car refers to temperature, which can be adjusted via buttons. It is generally located on the car's center console, and some models also have it at the rear air vents. However, rear independent air conditioning is typically found in high-end models. Below are the functions of a car's air conditioning system: 1. Temperature adjustment: In summer, the cooling system produces cold air to lower the cabin temperature; in winter, except for large commercial vehicles that use independent combustion heaters, most vehicles utilize residual heat for warming. 2. Humidity adjustment: Humidity significantly affects the thermal comfort of passengers. The cabin humidity should generally be maintained between 30% and 70%. Standard car air conditioning systems do not have humidity adjustment capabilities; this can only be achieved through ventilation or by installing advanced integrated heating and cooling systems found in luxury vehicles. 3. Airflow adjustment: Airflow speed and direction greatly impact passenger comfort. When the temperature is suitable, the air conditioning can adjust airflow speed based on factors such as passengers' living environment, age, health, and personal preferences. 4. Air purification: Cabin air quality is crucial. The air conditioning system helps maintain clean air and prevents bacterial growth.
I find setting the car air conditioning between 22 to 24 degrees Celsius is the most comfortable, which is the preferred range for most people. If the temperature is set too high (above 26°C) after starting the car, it can cause sweating during summer driving, affecting comfort. Setting it too low (below 18°C) may make the cabin uncomfortably chilly. I recommend starting at 23°C as a baseline, then making slight adjustments based on your daily comfort—for example, tweaking by 1 degree if you feel uncomfortable after half an hour of driving. Additionally, avoid setting the fan speed too high to prevent direct airflow from causing discomfort. Modern cars' AUTO function works well by automatically managing temperature and airflow, helping maintain cabin stability and reducing distractions for safer driving.
