Which button on the car's air conditioning is for cooling?

[StCharlie]

In the car's air conditioning system, pressing the AC button activates the cooling function. Here are detailed explanations about the car's air conditioning: 1. Cooling Details: The cold air from the car's air conditioning is produced by the compressor after it is turned on, and it only works when the vehicle is running. The compressor is driven by the engine's rotational torque. The AC button is the switch for the compressor; once activated, the compressor starts cooling. 2. Precautions: The car's air conditioning cooling system requires refrigerant. Refrigerant is volatile, so it should be stored away from direct sunlight, stoves, and other heat sources. Adding refrigerant should be done at low temperatures.
