Is the AC button in the car air conditioning for cooling or heating?

The AC button in the car air conditioning is the cooling switch, which refers to the air conditioning compressor switch. The cooling function of the car air conditioning is controlled by the AC switch on the air conditioning control panel. When the AC switch is turned on, the compressor's electromagnetic clutch engages, and the compressor starts working, enabling the car air conditioning to cool. The car air conditioning system consists of a compressor, condenser, throttle element, evaporator, fan, and necessary control components, which are used to regulate the temperature and humidity inside the car, providing a comfortable environment for passengers. The air conditioning also has an internal and external circulation switch. The internal circulation mode reuses the air inside the car, while the external circulation mode draws air from outside the car.
I found that the AC button in the car's air conditioning system is specifically designed for cooling. Many people mistakenly believe that pressing it will produce warm air, but this is a misunderstanding. Heating relies on the engine's heat, while the air conditioning system only blows air. When it's hot in summer, pressing the AC button activates the compressor, and cold air blows out, quickly cooling the cabin. In winter, I turn off the AC and just use the fan to blow warm air, which also saves some fuel since the compressor isn’t consuming power. Another common issue: if the windows fog up, turning on the AC removes moisture faster, much more effectively than using warm air. Remember to regularly maintain the cabin air filter to prevent bad odors and ensure a more comfortable ride. In short, the AC button isn’t for heating—it’s purely designed for cooling.
