How much fuel does it take to run the air conditioning in a car for an hour?

Generally the fuel consumption of a family car with the air conditioner on for an hour is about 1-3L.

According to different models, driving habits, the condition of parts and other factors, the vehicle's fuel consumption will be different, the car open air for an hour, idling state and driving state fuel consumption is different. In addition, according to different models, the results will have some deviation. Finally, the fuel consumption of the car after one hour in driving is also related to the adjustment of the engine by each brand, there is no accurate, standard and consistent answer to this question, because it is affected by too many objective factors.

When the vehicle is moving, it is more fuel-efficient to turn on the air conditioner when the speed is higher than 80 kilometers, and more fuel-efficient to turn on the air conditioner when the speed is lower than 80 kilometers. As we all know, the operation of air conditioning works through the compressor. The compressor is driven by the engine and when the engine is started, gasoline is used.

The amount of gasoline consumed by cars with different displacements is different, for example, a 1.4L car with air conditioning on for one hour will consume 2.4 liters of gasoline, while a 1.8L displacement car will consume a little more gasoline, and the fuel consumption of an hour with air conditioning on is about 4.35 liters of gasoline.

I, the car air conditioning precautions are:

1, start and rapid acceleration when off AC.

2, air conditioning temperature is not too low.

3, the owner of the car in the control of air conditioning vents, you can follow the air vents upward when turning on the cold air, when turning on the warm air will be the air vents downward.

4, do not open the air conditioning immediately after exposure to the sun.

5, turn off the air conditioning before turning off the engine.

Automobile air conditioning refers to the air conditioning device installed in the car, can be cooled, heated, ventilation and air purification of the air in the cabin, to provide a comfortable ride for passengers, reduce the fatigue intensity of the driver, improve the safety of driving, air conditioning device has become a measure of whether the car is fully functional as one of the signs.
