Washing machine energy class: What is it? What does it depend on?

In the house of a modern person there are various electrical appliances: a refrigerator, a hair dryer, an iron, a washing machine, which consume a huge amount of electricity. We make special demands on washing machines. They are obliged to wash our clothes perfectly, look beautiful, decorate the interior of the bathroom, and, most importantly, consume the minimum amount of electrical energy.

Manufacturers indicate data on power consumption in the passport for equipment and on a sticker on the back of the washing machine.

Energy class - what is it and which is better?

Energy class - what does it mean? Let's start with the definition of the concept of energy saving - this is an indicator of the efficiency of electrical energy consumption. But washing equipment cannot be completely energy-efficient, since its design provides for a powerful engine. Classes of washing machines are marked with English letters. Alphabet from A to G. The class definition method was defined in 1995.

The European Community adopted Directive No. 92/75/EEC, according to which European manufacturers of equipment had to complete their products with a sticker that would indicate the energy class of washing machines (from A to G), applied to a multi-colored ruler. Under laboratory conditions, a small contaminated piece of cloth is placed in the washing machine and washed for 1 hour at a temperature of 60 degrees.

The results are compared with the standard. An A-class washing machine should remove dirt better than the standard, class B - no worse than the standard. Currently, almost all all washing appliances are produced in the A-class. Energy class A is subdivided into "+", "++" and "+++". The more pluses, the better the quality of washing, and less energy is spent.

Cars marked "A" are bright green. A washing machine "A +++" requires less than 0.13 kW / h, "A ++" is enough for 0.15 kW / h per 1 kg of laundry, class "A +" is enough 0.17 kW / h, class " A "- from 0.17 to 0.19 kW / h. Class B washing machines can be identified by the pale green color on the scale. Class C and D are colored in shades of yellow, E, F, G are marked in red.

The total energy consumption is affected by the values ​​of four pantographs:

• - drive motor of the drum (activator), the power of which is measured in watts (from 180 to 800 W);
• - TEN - its power far exceeds the engine power and ranges from 180 to 80 watts. The heating element only works when the water is heated;
• - drain pump - low-power unit (24-40 W);
• - sensors, control unit, relays, indicator lights (5-10 W in total).

The maximum power of the washing machine reaches 4 kW.

It should be noted that many factors influence energy consumption:

1. - the service life of washing equipment. The older the washing machine, the more lime deposits it has on the heating element. At the same time, the time for heating water increases, increasing energy consumption;
   

2. – load size – the amount of electricity consumed is calculated per 1 kg of laundry. The more laundry we put in the drum, the more energy your washing machine will consume;

3. – the selected washing program – this primarily refers to the set washing temperature. The hotter the water, the more electricity is required to heat it.

Technologies that make the washing machine more economical. Some manufacturers independently develop technologies that help consumers save. And some buy technologies from developers and apply them in their products.

Here are some of the innovations that modern washing machines have become much more economical:

1. - inverter motor - thanks to innovative technology, the consumption of electrical energy has decreased significantly. washing machine brand LG considered the most economical;

2. - the system is intelligent - different manufacturers call it differently, but the principle of operation is the same. The possibility of dispensing water depending on the amount of laundry loaded makes the washing machine more economical. After all, the less water in the washer, the less electricity will be required to heat it.

3. - EcoBubble is the developer of this technology, Samsung Corporation, thanks to which washing machines of this brand have become more energy efficient. When mixing powder and water, air is added. Due to this, the amount of foam increases, easily penetrating into the fabric, better washing off dirt. Thanks to this development, effective washing at low temperatures is possible.
