The temperature of an air conditioner (AC) is not the same as the temperature outside. AC units are designed to cool the air inside a space, regardless of the temperature outside. The AC works by extracting heat from the indoor air and releasing it outside, which results in a lower temperature inside the room or building.
The AC temperature can be adjusted using a thermostat to maintain a comfortable indoor environment. You can set the desired temperature, and the AC will continue to cool the air until that temperature is reached. The AC unit does not directly measure or control the temperature outside; its purpose is to regulate the temperature indoors.
