The energy efficiency class of office equipment is a label that allows a person to evaluate the energy efficiency of devices due to full information about it.
Probably everyone has seen the stickers provided by the manufacturer. They are usually located on the front side of the device. This is the required marking. This information must be used if you want to choose a powerful and economical technique. That is what the energy efficiency class was created for. But how to use the information on the label correctly? Let's take a look at this.
Marking
This is a fairly simple task. You must select equipment that bears the Class A, A+, A++, or A+++ markings. To calculate the energy efficiency, it is necessarysummarize the mode of operation and certain technical characteristics that correspond to this type of equipment.
For example, consider the electricity consumption of a washing machine. How to do it? It is necessary to calculate the maximum load and energy consumption, which corresponds to an hour of work. If we consider the oven, then the electricity consumption will depend on the power and volume.
To effectively save electricity, you need to understand the technical characteristics. For example, for air conditioners, 3 parameters must be taken into account:
- channels that are located in the split system;
- presence or absence of water cooling;
- presence of heating.
Energy efficiency classes for household and office equipment in Russia - 7, and in the US and Europe - 10. These indicators should be paid attention to when choosing any equipment. All energy efficiency classes are shown on the label.
What do the different types of markings correspond to?
- The letter A, A+, A++ or A+++ indicates that the power consumption is 45% less than that of a conventional appliance. This marking is placed on high-quality and energy-efficient equipment that can serve for about 15 years.
- Letters B and C indicate less efficient appliances that consume 25% (for B) and 5% (for C) less electricity than standard appliances.
- The letters D and E correspond to the average energy efficiency. Expenseselectricity will correspond to standard appliances (for D). E-marked equipment consumes 10% more than conventional equipment.
- The last class is an uneconomical technique. Appliances labeled F and G will consume 25% more than standard counterparts.
Tables and their meanings
Today, the main direction in energy saving is the production of equipment that is created using new technologies. These devices try to make sure that they consume as little electricity as possible. All modern household and office equipment is created with this parameter in mind. Therefore, it is worth paying attention to the energy efficiency class of office and household appliances when choosing equipment.
As we found out earlier, this information is presented in the form of a sticker, on which there is a bright table with all the values. Usually glue it on the front side of the device.
If you choose the right equipment, you can choose economical equipment without any problems. Remember that the classification is the same for any appliances, but consumption rates may vary slightly. Therefore, when buying, it is worth considering the table of equipment energy efficiency classes.
Marking in EU countries
Energy efficiency classes were originally created in the European Union. Based on their information, some countries have begun to develop their own assessments for technology. But this did not become an obstacle to the spread of Europeansystems. Now on the vast majority of different devices you can see the European marking. It was introduced on the basis of studies by the EU Commission on Transport and Energy. Russia also adopted the developments that were made in the EU countries.
This energy efficiency step has many positive factors:
- people can save money by cutting down on utility bills;
- the state will be able to save resources and budget;
- this way you can save the environment;
- energy companies will reduce production costs;
- The most important thing is that you can reduce the use of natural resources.
Energy-efficient home appliances
Energy-saving equipment with Class A marking is quite common in the market. This contributed to the fact that some foreign companies introduced new designations for their equipment, namely: A+, A++ and A+++.
Refrigeration technology
Today, on any high-quality cooling equipment, you can see that manufacturers depict an energy efficiency index on the label. What does it depend on? It is calculated from the percentage of energy consumed per year and the energy consumption of a typical appliance 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: defrosting and temperature conditions. Also on the marking you can see the volume of working compartments.
The label of the refrigerator should bethe following options are displayed:
- Brand and manufacturer.
- To identify the technique, a special code must be displayed.
- Energy consumption 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, the energy efficiency class must be specified.
- The noise level of equipment during operation.
Washing machines
You can see different types of markings on washing machines. What does each of them correspond to?
Until 2010, energy efficiency was based on washing in the "Cotton 60" mode. This must be taken into account when the drum is fully loaded. Manufacturers had to fix how much electricity is spent for 1 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, a directive appeared, according to which it was customary to take into account 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 carried out at different types of load, that is, 42% - washing at full load and 60 degrees, 29% - partial load, half of which occurs at 60degrees, 29% - incomplete load, but washing at 40 degrees. Class A equipment consumes less than 340 kWh per year.
Washing machine labels usually indicate:
- As in the previous case, the brand and manufacturer are indicated, a code in the form of numbers and letters to identify the model of the corresponding manufacturer, energy efficiency class.
- Water consumption based on one year survey.
- Power consumption based on the same period.
- Energy efficient laundry drying.
- Maximum drum loading (this parameter is indicated in kilograms).
- The noise level of this equipment in the "Cotton 60 degrees" mode.
Dryers
To calculate the energy efficiency class for a dryer, it is necessary to consider the drying of laundry while the equipment is fully loaded. When assessing energy consumption, the parameter is taken into account - the number of kWh per 1 kilogram of laundry.
The label contains information about the brand and manufacturer, an alphanumeric code to identify the model, energy efficiency class.
Dryer characteristic parameters:
- energy costs for a certain period;
- mode of this equipment;
- loading the device;
- 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 mode of operation. Now the definition of the energy efficiency class involves the calculation of 275 washing cycles, they also began to take into account the standby mode. Efficient dishwashers consume 462 kilowatts a year.
Characteristic parameters that correspond to this type of technique:
- calculation of water consumption for 1 year of operation;
- power consumption;
- noise level;
- also takes into account the number of sets of dishes that are needed for a standard work cycle.
Lighting fixtures
To determine which class of energy efficiency of household appliances a lamp belongs to, it is necessary to take into account the consumed electricity. Next, you need to compare it with old incandescent lamps.
Energy efficiency classes of lamps:
- The letter A includes LED and fluorescent types, as well as some closed bulb fluorescent lamps.
- Class B includes certain closed bulb fluorescent and halogen infrared lamps.
- If the letter C is on the label, it is a xenon halogen lamp.
- Classes D, E, F include various halogen types.
- The last ones are incandescent lamps. They correspond to markings from E to G.
Office household special equipment. Energy Efficiency Class
Sorry,today there are no energy class tables that fit every office appliance. This can be explained by the fact that this type of technology is very diverse. In this wide range, there is a rather large variation in the technical parameters and orientation of a particular device.
How to determine the energy efficiency class of office appliances? To reduce electricity consumption, you need to choose modern models of office equipment. Each new generation consumes less electricity, but surpasses the old models in terms of technical characteristics. For example, ray tube monitors need to be replaced with modern LED screens, which consume much less electricity.
The energy efficiency class of a computer is difficult to define as 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 a computer is largely determined by the power supply. That is why a certification program was developed for them. Now it is recommended to buy power supplies that are marked - 80 PLUS. Remember, the higher this value, the more economical and reliable this part is.
Conclusion
If you want to choose appliances that will consume little electricity, you need to familiarize yourself with the energy efficiency classes of office equipment. Of course, if the required types do not have the appropriate markings, then it is better to choose a new technique. It is usually quite efficient, powerful and consumes little power. For example, if you want to choose a printer, then you need to look at the table of printer energy efficiency classes. Thus, you can choose a quality model.
