How much does the fuel consumption increase after turning on the air conditioning in a Baojun?

After turning on the air conditioning in a Baojun, the fuel consumption per 100 kilometers increases by 0.6L-1.5L. Principle of air conditioning refrigeration: The compressor of the air conditioning system compresses the refrigerant, which then expands through a valve. The expansion releases heat, causing the temperature of the refrigerant to drop. The refrigerant flows into the evaporator inside the car, absorbing heat from the cabin air through contact with the evaporator. It is then compressed again and expands once more, repeating this cycle to gradually remove heat from the cabin air. Air conditioning mode settings: In summer, use the recirculation mode more often when running the air conditioning. In winter, use the external circulation mode more often when using the heater. Use recirculation when the air quality is poor and external circulation when the air quality is good. On rainy days, if you want fresh air without opening the windows, use external circulation, which has the same effect as opening the windows.
Turning on the AC does significantly increase fuel consumption, mainly because the compressor requires additional power from the engine. Based on my observations of many car owners, fuel consumption typically rises by 10% to 15%, depending on the vehicle model and usage conditions. As an economical brand, Baojun's small-displacement engines are more noticeably affected under heavy loads. For example, in city driving combined with hot weather, fuel consumption may jump from the usual 7L/100km to over 8L/100km. It's recommended to keep the AC filter clean and set the temperature at around 26°C for a balance between comfort and fuel efficiency. Driving habits also play a crucial role, such as avoiding sudden acceleration or frequently turning the AC on and off in traffic jams. Overall, don't worry too much about the increased consumption—safety and comfort come first in summer. Regular maintenance checks can slightly mitigate the impact.
