What is the standard temperature for car air conditioning?

[SanIris]

There is no standard temperature for the air coming out of a car's air conditioning vents. In cooling mode, a vent temperature around 10 degrees Celsius is considered normal. If the vent temperature is too high, it indicates poor cooling performance in the air conditioning system. The reasons for poor cooling may include refrigerant not being replaced for a long time, damage to the compressor clutch, or compressor failure. Considerations for selecting air conditioning temperature: 1. Avoid setting it too low: Some people set the temperature very low for quick cooling, which may feel comfortable initially. However, this can disrupt the body's endocrine system. If the indoor temperature is set too low, such as below 20°C, it can cause various discomforts like leg pain, general fatigue, chills, and headaches. If there are elderly or children in the car, it's better to set the temperature at 27°C. 2. Temperature difference: Normally, the temperature inside the car should be about 5°C to 6°C different from the outside temperature. Therefore, when adjusting the temperature, it's best to refer to the outdoor temperature.
