What is the standard temperature for car air conditioning vents?

[DeAxel]

The standard temperature for car air conditioning vents is approximately 4 to 10 degrees Celsius. The method to check the vent temperature is as follows: 1. Set the air conditioning to maximum cooling and high fan speed, selecting the direct airflow position; 2. Open all vents, activate air recirculation and the AC switch, and ensure all doors are closed; 3. Increase the engine speed to 3000 rpm, insert a thermometer into the direct airflow vent, and measure the vent temperature for about 10 minutes. If the thermometer displays a temperature between 4 to 10 degrees Celsius, the car air conditioning vent temperature is normal. Car air conditioning, short for car air conditioning system, is used to regulate and control the temperature, humidity, air cleanliness, and airflow inside the car cabin to an optimal state.
