What is the best energy consumption class for a freezer?

A freezer is a household appliance that allows you to store food at subzero temperatures for a long time. If you are not satisfied with the freezer size of a standard refrigerator, purchasing a separate freezer cabinet may be a solution.

This equipment has several important parameters that need to be taken into account when choosing a specific model: dimensions and volume, freezing class, power, climate, availability of various functions, etc.

This article will discuss such an important parameter as energy efficiency. It certainly needs to be taken into account when choosing any electrical appliance, but in the case of a freezer, the energy efficiency class is especially important for two reasons:

• firstly, a refrigerator is a powerful device that consumes a large amount of energy;
• secondly, it is characterized by the fact that it is constantly on, which means it continuously consumes energy.

Which energy class freezer is best to choose?

It is no secret that throughout the world, electrical energy is an exhaustible, limited and rather expensive resource, which they are trying to save at both the state and household levels.In this regard, manufacturers of electrical appliances are trying to use circuit solutions that can make their products the most energy efficient. But how to measure this parameter?

In European countries, at the beginning of the 2000s, they came up with a system of energy efficiency classes for appliances. Since the beginning of 2011, by Government Decree No. 1222 of December 31, 2009, a similar system for certain types of electrical products was introduced in the Russian Federation.

Initially, 7 classes of energy efficiency of devices were defined, which were designated by capital letters from A to G. For greater clarity, each letter was assigned a color in a gradient from green (the highest) to red (the worst efficiency). At the same time, a conditional level was determined corresponding to the average energy consumption of devices of a certain group.

IMPORTANT! Each product group has its own energy efficiency indexing.

Since manufacturers are constantly working to improve the performance of their products, category A has been supplemented with three more subcategories. So the exhaustive list is as follows:

• A+++;
• A++;
• A+;
• A;
• B;
• C;
• D;
• E;
• F.

The class is determined by the energy efficiency index, which shows the ratio of the actual energy costs of a particular device to the nominal (averaged values).

A+++

A+++ is today an indicator of the most energy-efficient equipment. This indicator applies to a small number of expensive modern models of refrigerators and freezers. This technique has an efficiency index of less than 22.This means that they consume less than 22% of electricity than an average energy efficient appliance. Moving on to a practical level, we can say that a class A+++ freezer will consume approximately 5 times less energy. If you multiply this coefficient by the power consumption, the cost of 1 kW, and the number of hours of operation per year, you will get an amount that means how much such a miracle device will allow you to save per month on energy consumption alone.

A++

It corresponds to an index in the range from 22 to 33. Freezing units with this index also belong to highly efficient devices with a consumption of less than 0.15 kWh/kg. Such equipment will be somewhat cheaper and more represented on the market.

A+

These freezers consume only 32–42% of the conventional average model, which is also very good. Their consumption will be only 0.17-0.15 kWh for each kilogram of frozen contents. It is also advisable to purchase such equipment if it satisfies all other important parameters for you.

The first three classes lie in the high energy efficiency zone and are marked in green.

A

Devices of this class correspond to the index 42–55. Some 10–15 years ago these devices would have been considered the most energy efficient, but now they can rather be classified as economy class. You can purchase them due to their significantly lower cost for occasional use, for example, at the dacha for short-term use or seasonal use.

IN

Today, this category contains the most low-efficiency devices with an index from 55 to 75. Purchasing such equipment is hardly advisable.

C–G

Such freezing units can no longer be found often among suppliers and manufacturers of household appliances. Below is a table with the energy efficiency indicator of each of the remaining classes.
