Overall, the difference in fuel consumption between using the AC and not using it is not very significant, typically around 0.5-1L per 100 kilometers. Below is an introduction to car air conditioning: 1. Introduction to Car Air Conditioning: Car air conditioning consists of a compressor, condenser, throttle element, evaporator, fan, and necessary control components. It is an air conditioning system designed to regulate the temperature and humidity inside the vehicle, providing a comfortable environment for the driver. 2. Working Principle: When the compressor operates, it draws in low-temperature, low-pressure gaseous refrigerant from the evaporator. After compression, the temperature and pressure of the refrigerant increase, and it is sent to the condenser. Inside the condenser, the high-temperature, high-pressure gaseous refrigerant transfers heat to the outside air passing through the condenser, causing it to liquefy into a liquid. The liquid refrigerant then flows through the throttle device, where its temperature and pressure decrease, and it enters the evaporator. Inside the evaporator, the low-temperature, low-pressure liquid refrigerant absorbs heat from the air inside the vehicle passing through the evaporator, causing it to evaporate into a gas. The gas is then drawn back into the compressor to begin the next cycle.
