How much is the cooling air related to fuel consumption?

Use air conditioning at home

The lower the temperature, the more electricity you use

The higher the wind speed, the more electricity you use

Is that true of cars?

Master Bang will tell you about it

Cool air meeting

Increase fuel consumption?

First of all, the principle of car air conditioning refrigeration and home air conditioning is not much different, all work through the compressor, and open the air conditioner is the blower and compressor to work at the same time, so open the air conditioner fuel consumption will increase.

The higher the wind speed

Higher fuel consumption?

The effect of wind speed on fuel consumption is not large, because the wind speed is only related to the gear position of the blower, and the fuel consumption generated can be almost negligible.

The size of the air output only affects the speed of cooling in the car, and will not affect the compressor power. So fuel consumption is not affected.

The lower the temperature

Higher fuel consumption?

Now the car air conditioning is generally divided into automatic frequency conversion and manual frequency.

If it is a manual fixed-frequency air conditioner, it is not necessary to deliberately adjust the temperature and wind speed, because it is a fixed displacement, as long as the air conditioner is opened, the fuel consumption is almost fixed, which has nothing to do with the temperature and air volume.

If it is an automatic variable frequency air conditioner, when the temperature in the driver's compartment reaches the set temperature value, the compressor will stop working, and the relative fuel consumption will be less. The lower the temperature setting, to reach the ideal temperature, the compressor will work for a while longer, and the fuel consumption will increase accordingly.
