The classification of household appliances by energy consumption was introduced in Europe in the mid-90s. Since 2011, such markings on large household appliances must be included in Russia, which include refrigerators, washing machines and dishwashers , electric stoves and ovens, freezers , air conditioners and heating appliances, televisions, microwave ovens, electric lamps and water heaters. Each household appliance must have a sticker that indicates the class of energy consumption. Similar information is duplicated in the passport.
The energy consumption class is denoted in Latin letters from A to G. The most economical class A appliances, the highest
energy consumption for class G appliances. Recently, a new generation of household appliances with ultra-low consumption has appeared, it is denoted as super A, A +, A ++. For ease of perception, the letter designation corresponds to a certain color. Energy class A is marked in bright green, class B is light green, D is yellow, and G is red.
To make it clearer what role this parameter plays, consider refrigerators - they work almost around the clock, and their share in energy consumption is palpable. To determine the class, they take the actual value of electricity, established experimentally, and divide it into a standard value, which is determined by a complex formula with many components. For class A, this ratio is 42-55%, energy class B - 56-75%, C - 76-90%, D - 91-100%, classes E, F, G - above 100%. For super-economical models
A +, A ++, A +++ - less than 41%. As you can see, economical models consume three times less electricity than the norm.
For air conditioners, the energy consumption class is determined by two indicators: the ratio of the produced cold and the energy spent at the same time and the same ratio only for heating. For dishwashers, water consumption is a priority. For washing machines, this parameter is determined based on the energy consumption per kilogram of washed laundry. When determining the energy class for ovens, their volume and current consumption are taken into account, for TVs, the ratio of energy spent to the screen area is calculated.
The use of high-class electrical appliances will significantly save on electricity costs , however, the cost of models with a high energy consumption class is much higher. This is due to the use of more modern, technologically more complex, and therefore more expensive elements.
When choosing new equipment, in addition to design, the manufacturer's company, dimensions and power, pay attention to the energy consumption class. In addition to significant budget savings when paying electricity bills, the widespread adoption of cost-effective technology will reduce the cost of natural resources, many of which are non-renewable. This, in turn, will help to slightly improve the environmental situation, which is complicated from year to year.
