What is the temp setting for cold air in a car?
3 Answers
In a car, temp 18°C is considered cold air. Below is relevant information about car temp: 1. Definition: Temp in a car refers to temperature, which can be adjusted via buttons. The temp button is generally located on the car's central console, and some models also have it at the rear air vents, allowing independent control of the rear air conditioning temperature. 2. Adjustment Method: There is a temperature adjustment knob on the car's dashboard, with one side red and the other blue. Turning it all the way to the red side produces hot air, while turning it all the way to the blue side produces normal temperature air. To get cold air, you also need to press the compressor AC switch to activate the cooling system and produce cold air.
When it comes to setting the car air conditioning to cold air, over the years of driving, I've found that adjusting the temperature to around 18°C is the most suitable cooling state. Setting it too low, like below 16°C, can feel freezing, while setting it above 20°C is closer to cool air. The manual mode is straightforward: turn the temperature knob to the left to cool down, and remember to press the A/C button to activate the compressor for cooling. Without turning on the A/C, simply lowering the temperature might only result in natural air that's not cold enough. I usually set it to 20°C as soon as I get in the car during summer. If the car has a digital display, you can see the numbers change very quickly. Don't forget to turn on the external circulation to let fresh air in, otherwise, it can get stuffy, but don't leave it on for too long to avoid overloading the air conditioning. Regular maintenance is crucial, such as checking the filter to ensure it's not clogged, otherwise, the cooling effect will be poor, it will consume more fuel, and it will affect comfort and even health. In actual driving, different car models may show significant differences in temperature display, but generally, anything below 22°C can give you a chilly feeling.
I think the car air conditioning temperature settings are very smart, especially with the automatic AC—just press the AUTO button, and it automatically balances the cool and warm air. When set below 20°C, the system prioritizes blowing cold air for maximum cooling as the compressor activates. A temperature display between 18-22°C ensures continuous cold air output, while higher settings like 24°C may mix in warm air. The electronic control unit monitors the cabin temperature in real-time and optimizes airflow based on the set value. If the air doesn’t feel cold enough, check the refrigerant level or system faults—regular maintenance ensures efficiency. Modern cars even allow fine-tuning via the central screen; I often set it to 19°C to beat the heat. Understanding this helps save energy, prevent compressor overuse, and extend the system’s lifespan.
