The German Automobile Club (ADAC) has said that the car air conditioner consumes a large amount of fuel in the summer if it is not used properly.
German experts have explained that under extreme outside temperatures, the air conditioner consumes fuel at the beginning of the cooling phase at a rate of 2.5 to 4 liters / 100 km. After cooling the car, the consumption rate is between 1 and 2 liters / 100 km in the city and between 0.2 and 0.7 liters / 100 km outside the city.
To reduce fuel consumption, German experts advise that the car is well ventilated before starting, by opening the doors and windows for several minutes. While driving, the air circulation fan should be on for a short time and the air conditioner should be on.
It is best not to operate the air conditioner in short distances less than 5 km and open the windows while walking.
On the other hand, the German experts have shown that the control of the air conditioner at a very low temperature not only increases fuel consumption, but also poses a health risk; it causes problems of the circulatory system and the impact of muscle or cold stress
