When choosing a new refrigerator, many are faced with the marking energy class A and wonder: what does this mean in practice? How many kilowatts does such a unit “eat up” per month, and how will this affect the electricity bills? In this article we will analyze real consumption figures, compare class A with more modern A+, A++ and A+++, and also tell you how to reduce costs without compromising the safety of products.
Spoiler: class refrigerator A does not always mean “economical” - it all depends on the volume, type of compressor and even how you operate it. For example, A two-chamber unit with a volume of 350 liters with class A can consume up to 450 kWh per year, while the A+++ model of the same volume is only 180 kWh. The difference in electricity bills over 5 years of operation can amount to more than 20 thousand rubles!
But do not rush to run to the store for a model with the maximum quantity pros. It is not always the case that overpaying for a class will pay off even within 10 years. We will help you figure out when it makes sense to choose a particular class A+++ will pay off even in 10 years. We will help you figure out when it makes sense to choose a class. A, and when it is better to pay extra for more energy-efficient equipment.
What is energy consumption class A and how is it determined
Energy efficiency class A is a standard that appeared in the EU in the 1990s for labeling of household appliances according to the level of electricity consumption. Initially, it designated the most economical models, but with the development of technology, classes A+, A++ and A+++appeared, which are superior to A in efficiency by 10–50%.
Today class A is considered average energy efficiency. It is suitable for budget models and refrigerators with a large volume, where high efficiency is difficult due to technical features (for example, two-compressor systems or No Frost).
- 🔹 Energy efficiency index (EEI) is a key parameter. For the class A it is
42–55%(the lower, the better). For example, EEI 44% means that the refrigerator consumes 44% of the standard for its volume. - 🔹 Consumption standard is calculated using a formula that takes into account the volume of the refrigerator and freezer compartments, climate class and type of defrosting For a model with a volume of 300 liters, the standard can be ~350. kWh/year, and class A means consumption of no more than 192 kWh/year (55% of the norm).
- 🔹 Changes in the labeling: from 2021 in the EU they have returned to the scale from A to G (without pluses), but in Russia and the CIS countries the old system is still in effect. Check the labeling on the label!
⚠️ Attention: If you see a class A with a green arrow on the refrigerator, but without pluses, this may be new scale (2021+), where A is no longer the most economical option. Compare consumption figures (kWh/year), not just letters!
How many kW does a class A refrigerator consume in month and year
Electricity consumption by a class refrigerator A depends on three key factors:
- Volume of chambers: the larger the refrigerator, the higher the consumption. For example, a single-chamber 150-liter model consumes ~150–200 kWh/year, and a two-chamber 400-liter model consumes up to 450–500. kWh/year.
- Compressor type: inverter compressors are 15–25% more economical than conventional ones. A refrigerator with an inverter class A can consume the same as a model A+ with a conventional compressor.
- Climate class: equipment for hot climates (T or ST) consumes more energy than for moderate climates (N).
In the table below - average consumption values for refrigerators of class A of different volumes (data for climate class N, conventional compressor):
| Volume (l) | Consumption per year (kWh) | Consumption per month (kWh) | Cost per month (at a rate of 5 rubles/kWh) |
|---|---|---|---|
| 100–150 | 150–200 | 12–17 | 60–85 ₽ |
| 160–250 | 220–300 | 18–25 | 90–125 ₽ |
| 260–350 | 300–400 | 25–33 | 125–165 ₽ |
| 360–500 | 400–500 | 33–42 | 165–210 ₽ |
Example: refrigerator ATLANT XM 4021-000 (class A, 340 l) consumes ~360 kWh/year, that is ~30 kWh/month. At a tariff of 5 rubles/kWh, this will cost 150 rubles monthly. For comparison, a model Samsung RB-30 J3200SA class spends the same amount. ~250 kWh/year (21 kWh/month), saving ~500 rubles per year. A+ of the same volume spends ~250 kWh/year (21 kWh/month), saving ~500 rubles per year.
Class A vs A+, A++, A+++: is it worth it overpay
The difference in consumption between classes can reach 40–50%. For example:
- 🔌 Refrigerator Indesit DF 4180 W (class A, 320 l) - 350 kWh/year.
- 🔌 Model LG GA-B409 SLGL (class A++, 323 l) - 200 kWh/year.
At first glance, the overpayment for the class A++ pays off for 3–5 years. But there are nuances:
⚠️ Attention: Manufacturers often underestimate actual consumption in technical specifications. Actual consumption may be 10–15% higher due to:
- 🔥 Frequent opening of the door (especially in hot weather). data-i="136">❄️ Icing of the evaporator (if not defrosted on time).
- ❄️ Icing of the evaporator (if not defrosted on time).
- 🔌 Power surges in the network (the compressor runs longer).
Before purchasing, check real reviews about the model - users often share data from meters. For example, refrigerator Bosch KGN39XL20R class A+++ according to the passport, consumes 173 kWh/year, but according to reviews - up to 220 kWh/year with intensive use.
How to reduce the consumption of a class A refrigerator
Even if your refrigerator does not belong to class A+++, you can reduce its “appetite” by 20-30%. methods proven methods:
Set the temperature to +4...+5°C in the refrigerator compartment and −18°C in the freezer|
Move the refrigerator from the wall 5-10 cm for ventilation|
Do not put hot dishes (let cool to room temperature)|
Check the door seals for leaks (test with a sheet of paper)|
Defrost the refrigerator when the ice thickness is more than 5 mm-->
One of the most effective techniques is download optimizationThe refrigerator spends more energy if:
- 🥩 The chamber is filled to capacity with products (air circulation is disrupted).
- 🥤 There are open containers with liquid on the shelves (humidity increases, the compressor runs longer).
- 🧊 The freezer is covered with ice more than 3–5 mm thick (heat transfer deteriorates).
Example: after defrosting and cleaning the back grill, a refrigerator Samsung RL-34 ECMS class A reduced consumption from 380 to 320 kWh/year (saving ~300 rubles per year) year).
Top 5 class A refrigerators with an optimal price/consumption ratio
We analyzed the 2023–2026 models and selected class refrigerators Athat offer best balance between price, volume and energy consumption:
| Model | Volume (l) | Consumption (kWh/year) | Average price (2026) | Features |
|---|---|---|---|---|
| ATLANT MXM 2835-90 | 345 | 300 | 32 000 ₽ | No Frost, inverter compressor, climate class SN-T |
| Biryusa 140 | 340 | 280 | 28 000 ₽ | Mechanical control, manual defrosting, low level noise |
| Indesit DF 5200 W | 320 | 310 | 35 000 ₽ | Electronic control, super freezing, antibacterial coating |
| POZIS RK-149W | 344 | 290 | 30 000 ₽ | Two-compressor, independent chamber control |
Pay attention to the model ATLANT MHM 2835-90: despite the class A, its consumption (300 kWh/year) is comparable to some refrigerators of the class A+ thanks to the inverter compressor. This is one of the best options in terms of price/quality ratio for families of 3-4 people.
When class A is the best choice, and when is it better to take A+++
Class A suitable in the following cases:
- 💰 Budget up to 30,000 ₽: the difference in price between classes A and A+++ can reach 15–20 thousand rubles.
- 🏡 Country option: if the refrigerator works only in the summer, the overpayment for A+++ will not pay off.
- 👨👩👧👦 Large family: for a volume of 400+ l the difference in consumption between A and A++ is minimal (only 50–80 kWh/year).
Class A+++ It is worth choosing if:
- 🔥 You live in a hot climate (room temperature above +30°C).
- 💡 Electricity tariff is higher than 6 rubles/kWh (for example, in Moscow or with a two-tariff meter).
- 🏢 The refrigerator works in the office or around the clock (shop, cafe).
Detailed calculation of payback
Suppose a class A refrigerator costs 30,000 rubles and consumes 400 kWh/year, and model A+++ costs 45,000 rubles and consumes 200 kWh/year. The difference in price is 15,000 rubles, savings on electricity (at a tariff of 5 rubles/kWh) is 1,000 rubles/year. The payback will be 15 years, which is longer than the average lifespan of a refrigerator (10–12 years). In this case, class A is more profitable.
Common mistakes when choosing a refrigerator based on energy consumption
Many buyers focus only on the energy efficiency class, forgetting about other important parameters. Here typical mistakes:
- Ignoring climate class. A refrigerator of class A for a moderate climate (N) in the heat will consume the same as a model of class B.
- Choice by volume “in reserve”. An empty refrigerator spends more energy cooling the air. For 1–2 people, 180–220 liters are enough.
- Trust only the label. Manufacturers may indicate consumption for ideal conditions (temperature +25°C, rarely opening the door). In reality, the numbers are higher.
⚠️ Attention: If you see a class refrigerator A with consumption of less than 150 kWh/year with a volume of 300+ liters, this is a reason to be wary. Perhaps the consumption of only the refrigerator compartment (without a freezer) is indicated or the data is outdated.
Example: refrigerator Stinol STS 167 class A in the characteristics it has a consumption of 230 kWh/year, but in fact (according to reviews) - 280–300 kWh/year due to poor thermal insulation.
FAQ: Answers to frequently asked questions
Is it possible to reduce the energy class of an old refrigerator to A?
No, the energy efficiency class is a technical characteristic that depends on the design of the compressor, thermal insulation and system cooling. However, you can reduce actual consumption by 15–20% by:
- Regular defrosting (ice 5 mm thick increases consumption by 10%).
- Replacing the door seal (if worn out).
- Install the refrigerator away from the stove and battery.
But even after this, the old class refrigerator C or D will not consume as much as a class model A.
Which refrigerator is more economical: inverter class A or regular class A+++?
Let's compare using an example:
- ATLANT XM 4021-000 (class A, inverter) - 360 kWh/year.
- Samsung RB-30 J3200SA (class A+, conventional compressor) - 250 kWh/year.
In this case, the class A+ wins. However, inverter models last longer (less wear on the compressor) and are quieter. If the difference in consumption is less than 50 kWh/year, it is better to choose an inverter.
Does the color of the refrigerator affect energy consumption?
No, the color of the body (white, black, metallic) does not affect consumption. However matte surfaces (for example, models LG Door-in-Door) heat up less from sunlight than glossy ones, which indirectly reduces the load on the compressor on hot days.
How much electricity does a class A refrigerator consume in standby mode (when turned off light)?
Refrigerators of class A (as well as other classes) do not consume electricity when the power is completely turned off. However, after switching on, the compressor operates in enhanced mode for 1–2 hours, consuming up to 0.5–1 kWh to restore the temperature.
If the lights are turned off frequently, it is recommended to use uninterruptible power supply (UPS) to start the compressor smoothly - this will reduce peak load.
How to check the real consumption of your refrigerator?
The most accurate way is to use wattmeter (for example, Robiton PM-1 or Elitech SP 1400). Connect the refrigerator through the device for 3-5 days and calculate the average daily consumption. Alternative method:
- Turn off all appliances in the apartment except the refrigerator.
- Take the readings of the electricity meter.
- After 24 hours, take the readings again - the difference will show the daily consumption.
Multiply the result by 30 to get the monthly consumption.
