What does AC mean in a sedan?

[VonJuliette]

AC in a car refers to the air conditioning cooling switch. AC stands for air-conditioner, which can also be understood as cold air. Here is an introduction about the AC in air conditioning: 1. When turning on the air conditioning, pressing the AC button activates the car's compressor, and the air conditioning blows cold air. If the AC is not turned on, the car's compressor remains off, and the system blows natural air. 2. The AC switch regulates the electromagnetic clutch. For the car's compressor to operate, the electromagnetic clutch must be activated by supplying power, which is done by pressing the AC button. This way, the car's compressor starts working, and the car blows cold air. 3. When using the car's air conditioning in winter, there is no need to press the AC button because the heating relies on the car's cooling system.
