Electricity consumption of the air conditioner depending on the class

An air conditioner of any type (split-system, monoblock, multisplit) is factory-labeled according to the class of energy consumption. For domestic and industrial air conditioners, the energy consumption classes are different.

Energy labeling of air conditioners

According to the class of energy consumption, air conditioners for apartments and offices (household) are divided into 7 classes.

They are designated by the Latin letters A - G. The most energy efficient equipment belongs to class A, that is, it consumes less. Class G air conditioners consume the most.

One of the important indicators of the electricity consumption of an air conditioner is the annual consumption. It is calculated like this:

the total capacity in cooling mode at maximum load is multiplied by 500 (this is the average operating time in hours).

Energy consumption of air conditioners

The energy efficiency class of an air conditioner is determined by how much electricity it uses. There are two factors that can be used to judge the efficiency of climate technology. The first indicator that influences the energy efficiency class of the air conditioner is the cooling capacity. This is the cooling capacity at maximum load, expressed in kilowatt hours.

The most important indicator of the energy consumption of an air conditioner is the Energy Efficiency Ratio or EER:

the cooling capacity is divided by how much electricity the air conditioner consumes.

The lower the power consumption of the air conditioner, the higher the EER:

Class A - EER above 3.2;
Class B - EER from 3.2 to 3.0;
Class C - EER- 3.0 to 2.8;
Class D - EER- 2.8 to 2.6;
Class E - EER from 2.6 to 2.4;
Class F - EER from 2.4 to 2.2;
Class G - EER up to 2.2.

The above figures are valid for multisplit and split systems only.

Heating capacity is important for both cooling and heating air conditioners. This is the heating power at maximum load in kilowatt hours. The coefficient of heating capacity, or COP, is calculated as follows:

Divide the heating capacity by an indicator that determines how much electricity the air conditioner consumes.

The higher the value, the lower the power consumption of the air conditioner.

Energy efficiency classes of air conditioners for heating:

Class A - COP above 3.6;
Class B - COP 3.6 - 3.4;
Class C - COP 3.4 - 3.2;
Class D - COP from 3.2 to 2.8;
Class E - COP from 2.8 to 2.6;
Class F - COP from 2.6 to 2.4;
If the COP reading is less than 2.4, class G is assigned.
