Energy efficiency classes for electric motors

The class of energy consumption, also known as energy efficiency class, is a subdivision of the scale of consumption of household appliances regulated by the European Union. It indicates precisely the annual consumption expressed in kWh of an appliance as letters from A + + to G.

The consumption bands corresponding to a class vary according to the type of appliance.

After more than a year after its entry into force (19 June 2010), recently (21 July 2011) became mandatory for all EU Member States to apply the provisions in the EU Directive 2010/30. This directive, approved by the European Parliament in May last year, Directive 2010/30/EU has not only introduced a new format for the European energy label applied to household appliances, as well as new fields of application.

Let's see the most innovative aspects introduced by the standard.

Fields of application:

If the label is in fact so far been applied only to refrigerators, freezers, washing machines, dishwashers, ovens and air conditioners, now it will be mandatory for all products which have a significant direct or indirect impact on energy consumption.

Introduction of new energy classes:

Another important change in the number of energy classes. At present seven (A to G) were adds three additional classes: A +, A + + and A + + +. In economic terms, choose an appliance class A +, A + + and A + + + means you benefit from additional savings compared to a device of the class A.

Obligations for retail stores:

In the European Union the sellers have the obligation to show the label next to each appliance, clearly indicating which class you place the model on sale (Directive 92/75/EC). Now, with the takeover of the new energy label, we must not imagine a replacement immediately and in full within the stores. Will endure a transitional phase, during which the points of sale will include both forms of labeling, one beside the other, pending introduction of new and future absolute label.

Excluding air conditioners:

The new classes will therefore be applied to a greater range of products, except for some types of air conditioners.

The reason is to be found in the publication of Regulation no. 626/2011 (integration of the Directive) which will apply with effect from 1 January 2013, the type of air conditioners air / air with an output power of cooling / heating up to 12 KW. Depending on the type of air conditioner and according to the diagrams in the Regulations, the application of the label will be done in a gradual manner.

News in the ratings:

The new labels will take into account both the energy efficiency index seasonal (SEER value) that the seasonal coefficient of performance (SCOP value). Also, take into consideration the annual energy consumption in kWh / year for heating and cooling and also of sound power levels of indoor and outdoor units (expressed in dB (A) re1 pW).

Let's follow the energy efficiency classes for each appliance.


Classes for refrigerators and freezers

These are the values ​​of consumption of a refrigerator held in camera under laboratory conditions:

Class Annual Consumption

A + + <188 kWh

A + 188-263 kWh

A 263-344 kWh

B 300-400 kWh

C 400 to 560 kWh

D 563-625 kWh

E 625-688 kWh

F 688 to 781 kWh

G> 781 kWh

The values ​​indicated refer to a hypothetical refrigerator X product in all classes of efficiency and valid to compare refrigerators identical in internal volume and arrangement of space and any different temperature zones inside. In practice, energy labels applied to refrigerators and the annual consumption therein is measured according to CEN EN 153 which contain a range of measurements and laboratory tests.

Classes for washing machines, dryers, washer-dryers

These are the values ​​of consumption of a washing machine that makes two washes the week of 5 kg of cotton garments at 60 º C:

Class Annual Consumption

A <247 kWh

B 247-299 kWh

C 299 to 351 kWh

D 351-403 kWh

E 403-455 kWh

F 455 to 507 kWh

G> 507 kWh


Classes for dishwasher

These are the values ​​of consumption of a dishwasher that washes ago 220 per year (about 4 per week) with 12 covered for a time:

Class Annual Consumption

A <232 kWh

B 232-276 kWh

C 276 to 319 kWh

D 319-363 kWh

E 363-407 kWh

F 407 to 450 kWh

G> 450 kWh



Classes for electric ovens

These are the values ​​of the annual consumption of a furnace used for firing cycles percent a year.

There are three separate tables, depending on the size of the oven.

- Ovens small volume (12-35 liters)

Class Annual Consumption

A <80 kWh

B 80 - 100 kWh

C 100 - 120 kWh

D 120 - 140 kWh

E 140 - 160 kWh

F 160 - 180 kWh

G> 180 kWh


- Ovens volume of medium (35-60 liters)

Class Annual Consumption

A <100 kWh

B 100 - 120 kWh

C 120 - 140 kWh

D 140 - 160 kWh

E 160 - 180 kWh

F 180 - 200 kWh

G> 200 kWh


- Ovens large volume (more than 60 liters)

Class Annual Consumption

A <100 kWh

B 100 - 120 kWh

C 120 - 140 kWh

D 140 - 160 kWh

E 160 - 180 kWh

F 180 - 200 kWh

G> 200 kWh


Classes for air conditioners

These are the values ​​of consumption of a split air conditioner with a cooling capacity of 5.7 kW, air-cooled, used for 500 hours per year:

Class Annual Consumption

AA <734-890 kWh

A <891 kWh

B 891-950 kWh

C 950 - 1018 kWh

D 1018 - 1096 kWh

E 1096 - 1188 kWh

F 1188 - 1295 kWh

G> 1295 kWh


Keep in mind that all the data reported in the above tables are based on a consumption measured in the laboratory, according to well-defined parameters, in practical consumption may be higher.

The energy efficiency class of the appliance is still within its specified energy label.
