Is the AC Switch for Heating or Cooling?

[DeJoel]

AC button is the cooling switch of the car air conditioning. After pressing the AC button, the car air conditioning will cool, so AC is for cold air. Related introduction about car air conditioning cooling is as follows: 1. After pressing the AC button, the compressor clutch will engage, and the engine will drive the compressor to operate. This allows the compressor to continuously compress the refrigerant and deliver it to the evaporator. 2. The AC button is the switch for the cold air conditioning. When pressed, the compressor works while the temperature control knob is adjusted to the cooling zone, and the blower is turned on (1, 2, 3, 4 gears). At this time, cold air will blow out. For heating, there is no need to press the AC button. 3. The AUTO mode is a unique function of the car's automatic air conditioning. It automatically selects whether to use cold or hot air based on the set interior temperature. However, the AC button does not need to be activated when cooling is not required, aiming to prevent the compressor from working unnecessarily to save fuel.
