Does the wind speed of automobile air conditioning affect automobile fuel consumption?

Will the wind speed of automobile air conditioning affect the fuel consumption of automobile? You may not believe this answer.

Now that we have a car, we don't have to worry about extreme heat and cold when we go out. As soon as we get on the bus and turn on the air conditioner, we will experience the most comfortable enjoyment. However, while enjoying air conditioning, fuel consumption will also increase. But many people think that as long as the wind speed is lowered, fuel consumption can be saved. But is there a relationship between air speed and fuel consumption? Let's analyze this problem for everyone. The answer may not be what you think.

The working principle of turning on cold air and warm air is different, so the influence on fuel consumption is also different. It's the coldest time in winter. Everyone turns on the warm air, but its wind speed will not affect the fuel consumption. Car air conditioning is different from air conditioning at home, especially warm air, because the heat it uses mainly comes from the engine. When the car is working, the engine is constantly heating, and under normal circumstances, it will dissipate heat through the water tank and coolant. The car is equipped with a blower, which directly blows the heat of the engine into the car to keep warm.

In other words, no matter whether you turn on the warm air or not, the engine must dissipate heat, so the influence of warm air on fuel consumption is not great, and the power of the blower is not great, which can be completely ignored. It can be seen that heating the car in winter has little effect on fuel consumption, so it has nothing to do with wind speed. However, it is also recommended that you wait until the engine works normally when using warm air, otherwise it will affect the engine.

The principle of turning on air conditioning in summer is more complicated, because it not only isolates the heat of the engine, but also plays a role in cooling down. The principle of refrigeration is the same as that of air conditioning at home, and the output of cold air is realized through the compressor. The power of the compressor is relatively large, so the fuel consumption will also increase, but it has little to do with the wind speed, because whether it is strong wind or small wind, it is only a matter of the gear position of the blower, while the cold air is mainly used by the compressor and the displacement of the car. The size of the air outlet only affects the temperature inside the car, not the compressor power. As long as the compressor is on, the fuel consumption will increase.

It can be seen that whether it is cold air or warm air, the wind speed will not be related to fuel consumption when driving. You may not believe this answer, because it is really different from conventional thinking. Relatively speaking, cold air consumes more fuel than warm air, but in the future, you don't have to worry about the air volume. As long as the air conditioner is turned on, it will consume fuel, regardless of the wind speed. Therefore, there is absolutely no need for car owners to deliberately lower the wind speed in order to save fuel.
