Summer fuel consumption suddenly increased? The culprit must be it!

Opening air-conditioning and fuel costs, each owner's friend must have had a deep understanding, and I don't have to say anything. However, how much it can cost and how much impact it has on power is why air conditioning in summer is more costly than in other seasons. Today, the master talks about the “fat” of air conditioning.

Why air-conditioning air-conditioning?

The entire refrigeration process of the air conditioning system is through the refrigerating liquid gasification and liquefaction regasification in the air conditioning system, absorbing the heat in the air, and manufacturing the cold air blown from the air passage.

This whole refrigeration process is easy to say. In fact, it needs a lot of energy to make it run. Where does the energy come from? Naturally, it is a car energy source engine. The “engine” air-conditioning compressor in the air-conditioning system is connected to the engine through a belt, so that the power provided by the engine is used, so that it is natural to use more fuel.

How much engine power can the air-conditioning compressor consume?

The answer given by many people on the Internet is "10 percent." The master thinks this answer is not very accurate, because the air-conditioning compressor power gap between models is not large, the common air-conditioning compressor power on the market is probably 2-4 Between kilowatts, and the power gap between various models sometimes very large, a home scooter's maximum power is often less than 100 kilowatts, and a sports performance car's maximum power of more than 200 kilowatts. So how much impact on power, or depends on your car engine power, that is, the greater your horsepower, the smaller the impact of air conditioning on power, and vice versa.

Why is air conditioning more expensive in the summer?

The higher the temperature and the higher the humidity, the higher the fuel consumption of the automotive air conditioner. For example, when the temperature is 20°C, the humidity is 50%, and people are more comfortable. The fuel consumption is 10% higher than the air conditioner. However, if the humidity is doubled and becomes 100%, it means that the moisture will not evaporate and the sweat will not evaporate. The water will be on the side of the car glass. The humidity on the side of the wall will be drip. At this time, the air conditioner was on, and its fuel consumption was 20% higher than it could be. You have already doubled the difference, one 10% and one 20%. Let's assume that the temperature doubles it, and the temperature at 20°C becomes 40°C, and then the humidity also doubles, from 50% to 100%. In this case, the maximum fuel consumption may increase by about 30%.

To be precise, how much more fuel will be consumed to turn on air-conditioning?

Why open air-conditioning fee? In fact, in the final analysis, air conditioning will affect the engine power. If you want to reach the target speed, the throttle will need to be a little deeper than usual. This will certainly increase the fuel consumption. How much more is it? You can compare your compressor's power to your engine's maximum power. For example, your car's engine's maximum power is 100, the air conditioning compressor's power is 10, and the average daily fuel consumption is 10L. Then you may burn fuel after you turn on the air conditioner. One-tenth higher than the daily fuel consumption, which is 11L.

In the face of increased fuel consumption, how can we save fuel? What are the fuel-efficient mistakes?

Diligence and thrift are one of the traditional virtues of our country. Naturally speaking, it is worthwhile to sing. It is natural that you want to save fuel and save money. However, as long as you do a truly effective fuel-saving method, those who seem to be fuel-efficient do not know how to save fuel. Take it quickly and change it.

Fuel-efficient approach: Develop good driving habits

Open air conditioning in summer is inevitable. After all, the car is to serve the people. On such a hot day, do not take the body into account because of a few oil money. If you really want to save fuel and maintain a good driving habit, do not drive hard. , It can also effectively reduce fuel consumption.

Fuel-saving misunderstanding: Air-conditioning wind speed has nothing to do with fuel consumption

In order to save, some friends often adjust the air volume of air conditioners to a minimum, thinking that the fuel consumption will be reduced. However, in fact, the control of air-conditioning air intake and air-conditioning cooling is actually a complete two systems. The air-conditioning air volume is not controlled by the air-conditioning compressor. The energy consumed is just the power of the fan's rotation. It will not affect the fuel consumption at all.
