Which part of the blue zone in car air conditioning is the coldest?

[StBrantley]

The colder side of the blue zone in car air conditioning is towards the bluer end. This is because the blue zone only adjusts the opening degree of the cold air inlet, which means it changes the temperature by adjusting the mixed flow of cold air entering the cabin, rather than altering the working state of the compressor. Therefore, there is no energy-saving effect. Air outlet temperature: The temperature at the car air conditioning outlet depends on the set temperature and the power of the cooling system. Generally, a temperature between 2°C and 10°C is considered normal. Among them, German and American vehicles typically have temperatures below 8°C, while Korean and Japanese vehicles are considered normal below 10°C. Judging abnormal temperature: If the thermometer shows a temperature between 4°C and 10°C, it means the car air conditioning outlet temperature is normal and meets the standard. If the temperature is outside this range, it indicates poor cooling performance, and the system should be checked and repaired.
