What does AC in a car mean?

[DeLydia]

AC in a car is the abbreviation of air-conditioner, which means the air conditioning cooling switch, and can also be simply understood as cold air. Here is its introduction: When the air conditioner is turned on, turning on the AC will activate the car's compressor, and the air blown by the air conditioner will be cold air. If the AC is not turned on, the car's compressor remains off, and the air blown will be natural air. Here are some precautions regarding the AC button: 1. Turning on the AC does not produce heat; the air blown is the heat from the radiator. 2. The AC in the car controls the compressor's operation and only provides cooling.
