What is the normal temperature range for car air conditioning?

[Kaylee]

Car air conditioning is generally considered normal when it is above 8 degrees Celsius. The temperature difference between the air outlet and the return air outlet should be at least 18 degrees Celsius in heating mode to be considered normal. The temperature at the car air conditioning outlet depends on factors such as ambient temperature and airflow volume, and there are national standards for the outlet temperature. The car air conditioning system, abbreviated as car AC, is used to regulate and control the temperature, humidity, air cleanliness, and airflow inside the vehicle cabin to an optimal state, providing a comfortable riding environment for passengers and reducing travel fatigue. Car air conditioning generally includes cooling devices, heating devices, and ventilation devices.
