What does AC mean in a car's air conditioning

[ColemanLynn]

In a car, A/C stands for the air conditioning cooling device, also known as the air conditioning cooling switch. Here is more information about A/C: 1. A/C is short for Air Conditioning in English, representing the air conditioning device. Pressing the A/C button activates the air conditioning to adjust the temperature according to the set value. At this time, the air conditioning compressor starts, increasing the engine load and fuel consumption. 2. The A/C switch is only used when turning on the air conditioning in summer. It is not used when turning on the air conditioning in winter. If this button is pressed in winter, the warm air from the air conditioning will not only fail to work but also increase the engine load, resulting in wasted effort. Additional information: The principle of air conditioning cooling is that the low-pressure vapor of the refrigerant in the cooling system is sucked into the compressor and compressed into high-pressure vapor, which is then discharged to the condenser. The indoor air continuously circulates, achieving the purpose of lowering the temperature.
