At What Temperature Can a Car Air Conditioner Cool?

[VonTalia]

Car air conditioner cooling temperature depends on specific conditions: 1. Manual air conditioners can cool at any temperature setting; 2. Automatic air conditioners require an external temperature of at least 5 degrees Celsius to cool. The steps to turn on a car air conditioner are: 1. Turn the knob in the air conditioning control area to the cooling or heating zone; 2. Press the AC button when cooling is needed. The car air conditioning system, abbreviated as car AC, is used to adjust and control the temperature, humidity, air cleanliness, and air flow inside the car cabin to an optimal state. Its components include: the refrigeration system, heating system, air purification device, and control system.

Whether the car AC can cool actually has no direct relation to the temperature setting - the key is whether the AC button is pressed. Even if you set it to 28°C, as long as the AC light is on, the compressor is working, it's just that the blown air isn't as cold. In summer, I prefer to first set the AC to lowest temperature with high fan speed for a few minutes to quickly cool down the cabin, then adjust to around 22-24°C for optimal comfort. Don't forget to turn on recirculation mode for faster cooling, but switch back to fresh air mode during long drives to avoid stuffiness. If cooling performance declines, it might indicate refrigerant leakage or a dirty condenser, requiring professional inspection.

The core of car air conditioning cooling lies in the compressor. As soon as you press the AC button on the center console, the compressor starts working. The temperature knob acts more like a temperature controller; setting it to 22 degrees makes it work harder to cool than at 28 degrees. From my own driving experience, on hot days, setting the temperature to the lowest and the fan to maximum right after getting in the car can make it comfortably cool in just five minutes. Remember to change the air conditioning filter every six months, as a clogged filter can affect cooling efficiency. If you notice weak airflow or insufficient cooling from the vents, the first thing to check is whether the refrigerant is low.

After starting the vehicle, press the AC button to activate the air conditioning compressor for cooling. The set temperature determines the cooling intensity. For example, setting it to 18°C will keep cooling until this temperature is reached. In practice, around 24°C is comfortable and fuel-efficient. It's recommended to first select the recirculation mode for quick cooling after turning on the AC, then switch to fresh air mode for ventilation when driving on highways. If the AC blows hot air, it might be because the AC is not turned on or there's a refrigerant leak.
