Class of energy efficiency of office equipment

The class of energy efficiency of office equipment is the marking, which enables a person to assess the energy efficiency of devices due to full information about him.

Probably everyone saw the stickers that the manufacturer provides. They are usually located on the front of the device. This is the required marking. This information should be used if you want to choose a powerful and economical technique. It is for this purpose that a class of energy efficiency is created. But how correctly to use the information on the marking? Let's look at this.

Marking

This is a fairly simple task. You must select the equipment on which the labeling of class A, A +, A ++ or A +++ is located. To calculate the energy efficiency, it is necessary to sum up the operating mode and certain technical characteristics that correspond to this type of equipment.

For example, you can consider the power consumption for a washing machine. How to do it? It is necessary to calculate the maximum load and the energy consumed, which corresponds to the hour of operation. If we consider the oven, then the consumption of electricity will depend on the capacity and volume.

To effectively save electricity, you need to understand the technical characteristics. For example, air conditioners need to take into account 3 parameters:

• Channels that are located in the split system;
• Presence or absence of water cooling;
• Availability of heating.

Classes of energy efficiency for household and office equipment in Russia - 7, and in the US and Europe - 10. These indicators, and you need to pay attention when choosing any equipment. All energy efficiency classes are shown on the label.

What do the different types of marking correspond to?

• The letter A, A +, A ++ or A +++ indicates that the consumption of electricity is 45% less than that of a conventional device. This marking is placed on high-quality and energy-efficient technology, which can serve about 15 years.
• The letters B and C indicate a less efficient technique, which consumes 25% (for B) and 5% (for C) electricity less than the standard technique.
• The letters D and E correspond to the average energy efficiency. The energy costs will correspond to standard instruments (for D). The equipment labeled E consumes 10% more than conventional equipment.
• The last class is an uneconomical technique. Devices labeled F and G will consume 25% more than standard analogs.

Tables and their meaning

Today, the main direction in energy saving is the production of equipment, which is created using new technologies. These devices are trying to make sure that they consume as little electricity as possible. All modern household and office equipment is created taking this parameter into account. Therefore, it is worth paying attention to the energy efficiency class of office and home appliances, choosing equipment.

As we already found out earlier, this information is made out in the form of a label on which is a bright table with all the values. Usually glue it on the front side of the device.

If you correctly approach the choice of technology, then you can easily choose economical equipment without special problems. Remember that the classification is the same for all appliances, but the consumption rates may be slightly different. Therefore, when buying it is worth considering the table of classes of energy efficiency equipment.

Marking in the EU countries

Energy efficiency classes were originally created in the European Union. Based on their information, some countries began to develop their own estimates for technology on their own. But this did not become an obstacle to the spread of the European system. Now on the vast majority of different devices you can see the European marking. It was introduced on the basis of the studies of the EU Commission on Transport and Energy. In Russia, they also adopted the developments that have been made in the EU countries.

Such a step on the effective energy expenditure has many positive factors:

• People can save money, as this will cut utility costs;
• The state will be able to save resources and budget;
• Thus saving ecology;
• In energy companies the production cost will decrease;
• The most important is that it is possible to reduce the use of natural resources.

Energy-efficient home appliances

Energy-saving equipment with class A marking is quite common in the market. This has contributed to the fact that some foreign companies have introduced new designations for their equipment, namely: A +, A ++ and A +++.

Cooling Technology

Today, on any quality cooling technology, you can see that manufacturers are putting on the label an energy efficiency index. What does it depend on? It is calculated from the percentage of energy consumed per year and the energy consumption indicator for a conventional device of the same type.

At the same time, in order to calculate the average electricity consumption, it is necessary to take into account the volume of the chambers, as well as additional characteristics: defrost and temperature conditions. Also on the marking you can see the volume of working compartments.

The following parameters shall be displayed on the refrigerator label:

• Brand and manufacturer.
• To identify the technique, a special code must be shown.
• Energy costs of this model for a certain period.
• The manufacturer must specify the volume of compartments in which the operating temperature is more than 6 degrees.
• Storage capacity in places where the operating temperature is less than 6 degrees. Such compartments should be marked with asterisks.
• Of course, an energy efficiency class should be specified.
• The noise level of machinery during operation.

Washing machines

On washing machines you can see different types of marking. What does each of them correspond to?

Until 2010, energy efficiency was based on washing in the "Cotton 60 degree" mode. This must be taken into account when the drum is fully loaded. Producers had to record how much energy was wasted per hour of work when washing one kilogram of laundry. It was also necessary to take into account that the initial temperature is 15 degrees.

Later there was a directive, according to which it was decided to take into account the annual electricity consumption. It is necessary to monitor the consumption of electricity in the operating mode and in the standby mode. Energy efficiency should be calculated based on 220 washes per year. Of course, they must be produced under different types of load, ie 42% - full load washing and 60 degrees, 29% - partial loading, half of which occurs at 60 degrees, 29% - incomplete loading, but washing at 40 degrees. The technique, which corresponds to class A, consumes less than 340 kW per year.

The marking for the washing machine is usually indicated:

• As in the previous case, the brand and manufacturer are denoted, the code in the form of numbers and letters to identify the model of the respective manufacturer, the energy efficiency class.
• Water consumption based on studies per year.
• Energy consumption based on the same period.
• Energy efficiency of drying clothes.
• Maximum loading of the drum (this parameter is indicated in kilograms).
• The noise level of this equipment in the mode "Cotton 60 degrees".

laundry dryer

To calculate the energy efficiency class for the dryer, you must consider drying the laundry during the full load of the equipment. When estimating energy consumption, the parameter - the amount of kWh per kilogram of laundry is taken into account.

The marking indicates information about the brand and manufacturer, an alphanumeric code to identify the model, a class of energy efficiency.

The dryer is characterized by the following parameters:

• Energy consumption for a certain period;
• Mode of this equipment;
• Device loading;
• Drying time, this characteristic is taken into account at full load;
• noise level.

Dishwashers

Until 2010, in dishwashers, in order to estimate energy consumption, it was necessary to take into account the energy expended and the operating mode. Now the definition of the energy efficiency class involves the calculation of 275 washing cycles, also began to take into account the standby mode. Effective dishwashers consume 462 kilowatts per year.

Characteristic parameters that correspond to this type of technology:

• Calculation of water consumption for 1 year of operation;
• Energy consumption;
• noise level;
• It also takes into account the number of sets of dishes that are needed for a standard cycle of work.

Lighting

To determine to which class of energy efficiency of household appliances the lamp belongs, it is necessary to take into account the consumed electricity. Next, you need to compare it with the old incandescent lamps.

Classes of energy efficiency of lamps:

• The letter A includes LEDs and fluorescent types, as well as some fluorescent lamps with closed bulbs.
• Class B includes certain luminescent flasks with closed flasks and halogen infrared lamps.
• If the marking shows the letter C, then this is a halogen lamp with xenon.
• Classes D, E, F include various halogen types.
• The latter are incandescent lamps. They correspond to the marking from E to G.

Office household special equipment. Energy efficiency class

Unfortunately, today there are no energy class tables that are suitable for every office device. This can be explained by the fact that this type of technology is very diverse. In this wide range there is quite a wide range in terms of technical parameters and directivity of a particular device.

How to determine the class of energy efficiency of office appliances? To reduce the power consumption, you need to choose modern models of office equipment. Each new generation spends less electricity, but in terms of technical characteristics it outperforms older models. For example, radiant tube monitors need to be changed to modern LED screens, which consume much less electricity.

The class of energy efficiency of a computer is difficult to determine, since it depends on many details. It should be remembered that gaming laptops will consume much more electricity than budget models. But this does not mean that new and expensive components will not be effective and reliable.

The energy efficiency class of the computer is determined to a greater degree by the power supply unit. That's why a certification program was developed for them. Now it is recommended to buy power supplies, on which the marking is indicated - 80 PLUS. Remember, the higher this value, the more this detail is more economical and reliable.

Conclusion

If you want to select devices that will consume little power, you need to familiarize yourself with the classes of energy efficiency of office equipment. Of course, if the necessary types do not have the appropriate marking, then it is better to choose a new technique. It is usually quite efficient, powerful and consumes little energy. For example, if you want to pick up a printer, you need to look at the printer's energy efficiency class table. Thus, you can choose a quality model.
