Class A in the refrigerator: decoding, advantages and how not to overpay for energy efficiency

When choosing a new refrigerator, you probably came across the marking energy class A on the sticker. But what is actually hidden behind this letter? Why are some models marked as A+++, while others are simply marked as A? And most importantly, is it worth overpaying for a higher class if your old refrigerator works properly?

In this article we will understand how refrigerators are classified by energy efficiency, how the classes differ A, B, C, D and new designations after 2021, and we will also learn how to calculate real energy savings. You will learn what factors influence electricity consumption besides class, and why sometimes a refrigerator with a class B may be more profitable than one with A+++.

Spoiler: energy efficiency labeling is not just a marketing ploy. It determines how much you will pay for light over 10-15 years of operation of the device. But there are nuances that manufacturers prefer to keep silent about.

What is the energy consumption class and how is it determined?

The energy consumption class is standardized assessment, showing how efficiently the refrigerator consumes electricity compared to other models of the same volume. The higher the class (closer to A), the less electricity the equipment consumes under the same conditions.

Until 2021, there was a scale from A+++ (the most economical) to D (least economical). However, with the introduction of new European standards, the scale returned to simple letter markings from classes A+++, A++ and A+ have been abolished., and the scale returned to simple letter markings from A to G. Now A this is no longer the highest class, but simply a good indicator.

How is a class determined?

• 🔬 Laboratory tests. The refrigerator is tested under standard conditions: temperature in the chambers +5°C (for the refrigeration room) and -18°C (for the freezer room), ambient environment +25°C.
• ⚖️ Comparison with the standard. Real consumption is compared with the standard consumption for a given volume.
• 📊 Energy Efficiency Index (EEI). The lower this index, the higher the class. For example, for a class A EEI should be ≤ 55.

⚠️ Attention: After 2021, the class A+++ on new models is a fake or remnants of old stocks. Officially, such marking no longer exists.

Deciphering classes: from A to G according to new standards

On March 1, 2021, new labeling rules came into force in the EU (and then in Russia). Now the scale looks like this:

* For refrigerators with a volume of 250–350 liters. Actual consumption depends on the model and operating conditions.

It is important to understand that class A according to new standards ≠ class A according to old ones. For example, a refrigerator that previously had a mark A+can now receive a class B or even C. This does not mean that it has become worse - just the criteria have become more stringent.

Manufacturers are required to indicate:

• 📋 Energy efficiency class (letter from A to G).
• 🔋 Annual electricity consumption in kWh.
• ❄️ Volume of the refrigerator and freezer compartments in liters.
• 🔊 Noise level in decibels.

Why did they change the class scale?

Old classes A+, A++, A+++ misled buyers: the difference in consumption between A+ and A+++ could be minimal (only 5–10%), but the price tag differed significantly. The new scale is more transparent and leaves room for future innovations (for example, class A is now almost not assigned to any model).

How class A affects energy consumption and light bills

Let's calculate how much you will save by choosing a class refrigerator A instead of C. Let's take the average figures for a model with a volume of 300 liters:

• 🔌 Class A: 220 kWh/year → ~1 100 rub/year (at a tariff of 5 rubles/kWh).
• 🔌 Class C: 350 kWh/year → ~1,750 rub/year.

Difference: 650 rubles/year or 6,500 rubles for 10 years. But this is in ideal conditions! The actual consumption depends on:

Factors that increase electricity consumption:

• 🌡️ Room temperature. If the kitchen is +30°C, the compressor works 20–30% more intensely.
• 🚪 Frequency of door opening. Each opening adds 5–10% to the consumption.
• ❄️ Ice crust thickness. Frozen ice worsens heat transfer - consumption increases by 15–20%.
• 📦 Loading of chambers. A crowded refrigerator requires more energy for cooling.

Conclusion: class A is really more economical, but the difference can be offset by improper operation. For example, a refrigerator of class B with a system No Frost and optimal loading sometimes spends less electricity than A with manual defrosting and a thick layer of ice.

Is it worth overpaying for class A: comparison with classes B and C

Manufacturers often impose the idea that class A is a mandatory minimum. But let's look at the real numbers. Let's compare three models of the same brand (Samsung RB30A32N0SA, Samsung RB30A34N0SA, Samsung RB30A36N0SA) with the same volume of 310 liters, but different classes:

* At a tariff of 5 rubles/kWh.

Conclusions:

1. Overpayment for class B instead C — 7,000 rubles, but savings over 10 years - only 3,000 rubles. Unprofitable.
2. Overpayment for class A instead of C — 15,000 rubles, savings - 5,500 rubles. Also unprofitableif you do not plan to use the refrigerator for 20+ years.
3. Exception: if you solar panels or have a night tariff for electricity, the higher class can pay off faster.

⚠️ Attention: Manufacturers often underestimate actual consumption in technical specifications. According to Roskachestvo, actual consumption may exceed the declared one by 10–25%. Always check owner reviews!

How to check the real energy class of your refrigerator

If you have already bought a refrigerator or are using an old one, here is how to find out its real class:

1. Look at the sticker on the inside of the door or in the device passport. Look for a color scale with letters from A to G.
2. Check the model in the Rostest database. The website Rosaccreditation has a register of certified equipment.
3. Use an energy meter. Connect the refrigerator through a metering device (for example, Elitech SP 180) and measure consumption per day. Multiply by 365 and compare with the stated data.

If there is no sticker or it has worn off, the class can be determined by year of manufacture:

• 📅 Before 2010: most likely, class D or lower.
• 📅 2010–2015: usually B or C.
• 📅 2016–2020: A+ or A++ (according to old standards).
• 📅 After 2021: class according to the new scale (from A to G).

For an accurate calculation, use the formula:

Real class ≈ (Actual consumption / Standard for volume) × 100%

The standard for a 300 liter refrigerator is about 400 kWh/year. If your appliance consumes 320 kWh, its EEI index = (320/400) × 100 = 80% → corresponds to the class C.

Set the temperature to +4...+5°C in the refrigerator compartment and -18°C in the freezer

Defrost the refrigerator with a layer of ice > 5 mm

Do not place near the stove, radiator or in direct sunlight

Check rubber seals for tightness (test with a sheet of paper)-->

Myths about class A: what sellers do not tell

Marketers actively exploit the topic of energy efficiency, but not all of their statements correspond to reality:

Myth 1: "Class A is always more economical, than B or C"

Reality: Profitability depends on cooling technologies. For example, a class refrigerator B with an inverter compressor (LG GA-B489YGLZ) can spend less electricity than a class model A with a conventional compressor, if the first one turns on less often.

Myth 2: “Class A refrigerators last longer”

Reality: Energy consumption class does not affect reliabilityThe service life depends on the quality of the compressor, the cooling system and operating conditions. For example, Atlantic ATL 2208 (class C) with proper care will last the same 15 years as Bosch KAN92VI30R (class A).

Myth 3: “All new refrigerators are class A"

Reality: According to new standards, the class A is almost not assigned! Most modern models receive B or Cbecause the requirements have become more stringent. For example, the flagship Samsung Bespoke RF23BB8600 (2023) has class B.

Myth 4: "Class A guarantees quiet operation"

Reality: Noise level and energy efficiency - different parameters. A refrigerator of class A can hum at 45 dB, and class C — operate almost silently (35 dB). Always check the decibels in the specifications!

How to choose a refrigerator: class A or other parameters?

Energy consumption class is an important, but not the only criterion. Here's what else you need. consider:

Selection algorithm:

1. Determine required volume (50–60 liters per person).
2. Select type defrosting (No Frost or drip).
3. Compare models by real consumption (kWh/year), and not just by class.
4. Evaluate additional functionsDo you need a freshness zone or. are standard shelves enough?
5. Check noise level (optimally ≤ 40 dB).

⚠️ Attention: B In 2026, some manufacturers began to indicate the energy consumption class only electronically (via a QR code on the sticker). Always scan the code before purchasing - this way you will see the full data, including annual consumption.

FAQ: Frequently asked questions about class A in refrigerators

Can I change the energy consumption class of the refrigerator myself?

No, the class is assigned at the production stage and depends on the design of the compressor, thermal insulation and cooling system. However, you can reduce actual consumption:

• 🔧 Defrost the refrigerator regularly (if not No Frost).
• 🌡️ Set the optimal temperature: +4°C in the refrigerator compartment, -18°C in the freezer.
• 🚫 Do not place near heat sources (battery, stove).

These measures can reduce energy consumption by 15-30%, but the class will not change.

Why is my new refrigerator class A consumes more than indicated in the specifications?

There are several reasons:

1. Test conditions ≠ real. Manufacturers measure consumption at +25°C in the room, but yours may be +30°C.
2. Frequent opening of the door. by 5–10%.
3. Incorrect loading. If the products are stored loosely or hot, the compressor runs longer.
4. MalfunctionCheck the seal, thermostat and ventilation (for models with No Frost).

For accurate diagnosis, use an energy meter or call a technician.

Is it worth buying a used Class A refrigerator?

It depends on:

• ⏳ Age of the modelIf the refrigerator is > 10 years old, even. class A according to old standards can correspond to modern ones C.
• 🔧 Compressor conditions. A worn-out compressor increases consumption by 20–40%.
• 💰 PricesIf it is a used refrigerator. class A cheaper than a new class B by 30%+, the purchase makes sense.

Checklist before buying a used one:

Look at the sticker with the class (must be original, not re-glued)

Check the compressor for rust and oil stains

Make sure that the rubber seals are intact and elastic

Turn on the refrigerator for 2 hours - it should gain temperature and turn off-->

What is the energy consumption class of Soviet refrigerators (ZIL, Minsk, Biryusa)?

Old Soviet refrigerators (ZIL-63, Minsk-15M, Biryusa-3) by modern standards belong to classes D–G. Their actual consumption is:

• ZIL-63: ~500–600 kWh/year.
• Minsk-15M: ~450–550 kWh/year.
• Biryusa-3: ~400–500 kWh/year.

For comparison: a modern refrigerator class B of the same volume (200–250 l) spends 250–300 kWh/year. Savings on replacement - up to 3,000 rubles/year.

However, Soviet refrigerators win in reliability and maintainability. If durability is more important to you than saving on electricity, they can be used further (provided the compressor is in good working order).

Does the energy consumption class affect the price of the refrigerator?

Yes, but not as much as other parameters. Here is an approximate relationship for models 2023–2026:

• Class A: +15–25% to the base price.
• Class B: +5–10%.
• Class C: base price (without extra charge for energy efficiency).

However, the price difference between classes A and B often pays off only after 10–15 years. For example:

• Bosch KAN92VI30R (class A) - ~70,000 rubles.
• Bosch KAN90VI20R (class B) - ~60,000 rubles.

The difference of 10,000 rubles will pay off in ~12 years (with savings of 800 rubles/year on electricity).
