What does AC in car air conditioning mean?

[Lilliana]

AC in air conditioning refers to the cooling switch. When AC is turned on, the car's compressor activates, and the air blown by the air conditioner becomes cold; if AC is not turned on, the compressor remains off, and the air blown is natural air. Here is an introduction to AC in air conditioning: 1. AC is the abbreviation for air-conditioner, meaning air conditioning, and can also be understood as cold air. The AC switch controls the electromagnetic clutch. For the car's compressor to operate, the electromagnetic clutch must be activated when powered, which is done by pressing the AC button. This way, the car's compressor starts working, and the air blown by the car becomes cold. 2. The functions of car air conditioning are as follows: (1) Control the temperature inside the cabin, capable of both heating and cooling the air to maintain a comfortable cabin temperature. (2) Remove moisture from the air. Dry air absorbs human sweat to create a more comfortable environment. (3) Filter the air, removing dust and pollen from the air.
