Which Button is the Air Conditioner in the Car?

[LeArcher]

In the car, the air conditioner is the AC button. When the AC button light is on, it indicates that the compressor is activated and the car air conditioner starts cooling. The air conditioner, short for the car air conditioning device, is used to adjust and control the temperature, humidity, air cleanliness, and air flow inside the car compartment to an optimal state. The functions of the air conditioner are: 1. Achieving a cooling effect through the continuous cycle of refrigerant; 2. Removing dust, odors, smoke, and toxic gases from the air inside the car, making the air fresher, and humidifying the air to increase its relative humidity; 3. Using engine coolant, waste heat, or heat generated by a burner as a heating source, warming the air through a heater, and then blowing it into the car compartment or outside air to raise the temperature at the air outlet for heating purposes; 4. Drawing in fresh external air for ventilation and air exchange, which also helps prevent window fogging.
