Classification of household electrical appliances by the level of energy consumption introduced in Europe in the mid-90's. In Russia, since 2011, this marking must necessarily be on large household appliances, which include refrigerators, washing machines and dishwashers , electric stoves and ovens, freezers , air conditioners and heaters, TVs, microwave ovens, electric lamps and water heaters. On each household electric appliance there must be a sticker, which indicates the energy consumption class. Similar information is duplicated in the passport.
The energy consumption class is denoted by Latin letters from A to G. The most economical class A appliances, the largest electricity consumption for class G devices. Recently a new generation of household appliances with ultra-small consumption has appeared, it is designated as super A, A +, A ++. For ease of perception, a certain color corresponds to the letter designation. The energy consumption class A is designated as bright green, class B - light green, D - yellow, G - red.
In order to understand what role this parameter plays, let's consider refrigerators - they work practically around the clock, and their share in the consumption of electricity is palpable. To determine the class take the actual value of electricity, established experimentally, and divide it by a standard value, which is determined by a complex formula with many components. For class A, this ratio is 42-55%, energy consumption class B is 56-75%, C is 76-90%, D is 91-100%, classes E, F, G are above 100%. For superseconomic models A +, A ++, A +++ - less than 41%. As you can see, economical models consume three times less electricity than the standard.
For air conditioners, the energy consumption class is determined by two factors: the ratio of the produced cold and the energy spent while maintaining the same attitude only for heating. For dishwashers, water flow is a priority. For washing machines, this parameter is determined based on the consumption of electricity per kilogram of laundry washed. Determining the energy consumption class for ovens, take into account their volume and current consumption, for TV sets calculate the ratio of energy expended to the screen area.
The use of high-end electrical appliances will save considerable energy 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.
Choosing a new technique, except design, manufacturer, size and power, pay attention to the energy consumption class. In addition to significant budget savings when paying bills for electricity, the widespread use of economical technology will reduce the costs of natural resources, many of which are non-renewable. This, in turn, will slightly improve the environmental situation, which is complicated from year to year.
