What is the normal temperature range for car air conditioning vents?
2 Answers
Car air conditioning vent temperature depends on factors such as ambient temperature and airflow volume. There are national standards for air conditioning vent temperatures. The temperature difference between the vent and return air vent should not exceed 8°C in cooling mode to be considered normal, while in heating mode, the temperature difference should be no less than 18°C to be considered normal. The method for checking car air conditioning vent temperature is as follows: 1. Before checking the car air conditioning vent temperature, set the air conditioning to maximum cooling, open all vents, activate air recirculation, turn on the A/C switch, and close all doors. 2. Increase the engine speed to 3000r/min, insert a thermometer into the direct vent to measure the air conditioning vent temperature for 10 minutes. If the thermometer displays a temperature between 4°C to 10°C, it indicates the car air conditioning vent temperature is normal and meets standards.
I think the normal temperature of car air conditioning vents is usually between 4 to 10 degrees Celsius, depending on the situation. For example, on hot summer days, after running the MAX cooling setting for 10 minutes, it's good if the temperature drops to around 5 degrees, providing a nice chilly breeze; if it exceeds 15 degrees, there might be issues like insufficient refrigerant or a faulty compressor. I've tested my own car with a thermometer, and at 30-degree weather, 8 degrees at the vent feels very comfortable. During regular maintenance, remember to clean the air conditioning filter to prevent dust from blocking airflow. Occasional checks can help detect faults early, reducing the risk of breakdowns, especially during long-distance drives when a well-functioning air conditioner prevents discomfort from heat. In short, the goal is to keep the car interior cool and comfortable, and don't overlook minor issues.
