The consumption of car air conditioning
When summer comes, driving without air conditioning can become a real ordeal on most Spanish roads. The air conditioning of the car becomes our salvation in these cases, but do you know that it is also a cause for concern about its possible fuel consumption?

The operation of the air conditioning system
The air conditioning system of a car applies various mechanical elements to get the indoor air to cool, filter its possible impurities and eliminate possible humidity. To this process must be added the mechanical compression of the refrigerant gas, which is repeated continuously while the air conditioning system is in operation.

All this refrigeration process involves the use of energy that is evidently obtained from the vehicle’s fuel.

Fuel consumption
The use of air conditioning increases the fuel consumption of the engine, although this increase depends on the work that we request from the system at all times.

As a general rule, we can say that the air conditioning system of a car can consume between 5% and 20% more than usual fuel, in the most extreme cases. This normally involves between 0.2 and 1 liter at 100 km.

Keep in mind that the more we want to lower the temperature inside the vehicle and the hotter the interior and exterior of the car, the more the system will have to work. Therefore, it will make a greater energy consumption.

Save fuel
Reducing the fuel consumption of the car involves establishing a series of basic measures.

Many people think that lowering the windows instead of using the air is essential to save, but we must take into account the speed at which we circulate. If we move at high speed, the normal thing will be that we worsen the vehicle’s aerodynamics and that, therefore, the engine has to work harder to move the car. As a result, it will consume more fuel
