How much electricity does a Samsung refrigerator consume per month: calculation and ways to save

The refrigerator is the only household appliance that works around the clock without interruptions. And if you are thinking about buying a model Samsung or are already using it, the issue of energy consumption becomes critically important. After all, not only environmental friendliness, but also your monthly electricity bill depends on this. In this article we will figure out what it depends on and how to reduce costs without compromising the safety of products. how much electricity a Samsung refrigerator actually consumes per month, what it depends on and how to reduce costs without compromising the safety of products.

The manufacturer always indicates the average annual consumption in the technical data sheet, but these figures often raise questions. How to convert them into monthly expenses? Why may actual indicators differ from those stated? And why do even two identical models Samsung RB37J5230SA and Samsung RB37J5230WW (differing only in color) sometimes show different consumption? The answers are below.

How the energy consumption of a Samsung refrigerator is calculated

All refrigerators Samsung are certified according to the standard ISO 15502, which determines the methodology for measuring energy efficiency. The manufacturer tests the device in laboratory conditions:

• 🔹 Ambient temperature: +25°C
• 🔹 Temperature in the refrigerator compartment: +5°C
• 🔹 Temperature in the freezer: -18°C
• 🔹 The doors open once an hour for 1 minute
• 🔹 Product loading: 50% of the volume

It is with these parameters that the passport indicates annual consumption in kWh. For example, for the model Samsung RL38T671CS8 this is 287 kWh/year. To get monthly consumption, it is enough to divide this figure by 12:

287 kWh ÷ 12 ≈ 24 kWh/month

But in real conditions the numbers can differ by ±30%! Why? Affected by:

• 🌡️ Room temperature (the higher, the greater the load on the compressor)
• 🚪 Frequency of door opening (each opening adds 5-10% to the flow rate)
• 🍖 Load level (an overloaded refrigerator spends more energy on cooling)
• ❄️ Operating mode (for example, Power Cool or Power Freeze increase consumption)

Comparison of Samsung models by energy consumption

The energy efficiency of refrigerators Samsung depends on class, volume and technology cooling. Modern models (produced after 2020) belong to classes A+++, A++ or A+, but even within the same class, consumption can differ by 1.5–2 times.

The table below contains real data on popular models (based on tests and user reviews). Please note: two-chamber refrigerators with No Frost they consume 10–15% more than models with a drip system, but do not require defrosting.

As can be seen from the table, even Side-by-Side models (for example, Samsung RS55N5700SA) with a large volume can consume less than small old-style refrigerators. It's all about inverter compressors, which automatically adjust power depending on the load. Modern Samsung models can withstand a shutdown of 6–8 hours without risk to the products. Digital Inverter, which automatically adjust power depending on the load.

How energy efficiency class affects consumption

Since 2021, the EU has a new energy efficiency scale (from A to G), but in Russia and the CIS countries they still use the old one marking (A+++, A++ etc.). Samsung indicates both options in the technical specifications. Let's figure out what this means in practice:

• 🟢 A+++ (or A on the new scale): lowest consumption (40–50% more economical A+)
• 🟡 A++ (B): average consumption, optimal price/quality balance
• 🔴 A+ (C): aging category, high consumption (more often models until 2018)

For example, a refrigerator Samsung RL34ECSW class A+++ spends ~25 kWh/month, and a model of similar volume Samsung RL33EAMS class A+ — already ~35 kWh/month. The difference in 10 kWh is 50–100 ₽ additional monthly expenses.

But there is a nuance: sometimes class refrigerators are A+ cheaper by 10–15 thousand rubles. In this case, will overpayments for electricity pay off? Let's calculate:

(35 kWh - 25 kWh) × 5 ₽ × 12 months = 600 ₽/year
10,000 ₽ ÷ 600 ₽/year ≈ 16 years (term payback)

Conclusion: if you plan to use the refrigerator for less than 10 years, there is no point in overpaying for A+++ e. But if your region has high tariffs (for example, 7–9 ₽/kWh), the savings will become more noticeable.

5 factors that increase energy consumption

Even the most economical refrigerator Samsung can begin to “eat” electricity if you do not follow simple rules. Here are the main reasons for increased consumption:

1. Incorrect temperature in the chambers

   Optimal settings: +4…+5°C for the refrigerator compartment and -18°C for the freezer. Each degree lower adds 5–8% to consumption. For example, if you put -24°C in the freezer, the compressor will work almost non-stop.

2. Dirty condenser

   Dust on the back wall of the refrigerator acts like a “fur coat”: it worsens heat transfer and makes the compressor work harder. You need to clean the grill once every 6 months (you can use a vacuum cleaner).

3. Tight fit to the wall

   If the refrigerator is standing close to the wall or furniture, air circulation is disrupted. Minimum gaps: 5 cm rear and 2 cm on the sides.

4. Frequent door opening

   Each opening adds 1–3 kWh per month. It is especially critical if there are children in the house who forget to close the refrigerator.

5. Outdated firmware

   In refrigerators Samsung with a display (series Family Hub) There is built-in software that optimizes the operation of the compressor. Updates come out every 1–2 years and can reduce consumption by 3–5%.

Set the temperature to +4°C in the refrigerator compartment|Clean the condenser 2 times a year|Do not put hot foods inside|Check the door seals for leaks|Disable the "Vacation" mode during long periods of inactivity-->

Another hidden "energy eater" - ice in the freezer. If the thickness of the ice exceeds 5 mmthe compressor spends 15–20% more electricity. In models with No Frost ice does not form, but if you have a drip system, defrost the refrigerator once every 3-4 months.

How to check Is the seal tight?

Take a sheet of paper (A4 size), close the refrigerator door, holding the sheet between the seal and the body. If the sheet is easily pulled out, the seal is worn out and needs to be replaced. This can add up to 10 kWh to your monthly consumption!

How much does it cost to maintain a Samsung refrigerator per year

To calculate the annual consumption, you need to multiply the monthly consumption by 12 and the tariff of your region. Let's take for example the model Samsung RB37J5230SA (26.7 kWh/month) and three different tariffs:

For comparison: an old class refrigerator C (for example, Samsung RL33EAMS, 2015) will cost in Moscow ~2,500 ₽/year, and a model A+++ (for example, Samsung RL38T671CS8) - total 1,320 ₽/year. The difference is 1 180 ₽which can be spent on something more useful.

But don’t forget: electricity tariffs are rising every year. If in 2020 the average tariff in Russia was 4.03 ₽/kWh, then in 2026 it was already 5.12 ₽/kWh (an increase of 27%). This means that in 5 years your refrigerator will “eat up” 30–40% more money from the budget.

How to reduce the consumption of a Samsung refrigerator by 30%

You can reduce energy consumption without buying a new refrigerator. Here 7 working methodstested in practice:

• ⚡ Adjust the temperature: install +4°C in the refrigerator compartment and -18°C in the freezer. Every extra degree of cold increases consumption by 5–8%.
• 🧊 Do not put hot products: cool them to room temperature. This will save up to 10 kWh/month.
• 🔄 Check the seals: if they are worn out, the cold “leaks away” and the compressor runs longer. Replacing the seal costs 1 500–3 000 ₽, but pays off in 1-2 years.
• ☀️ Keep the refrigerator away from the stove and radiator: the distance to heat sources should be at least 50 cm.
• 📱 Update the firmware (for models with Family Hub): new algorithms optimize the operation of the compressor. The update is free and takes 10–15 minutes.
• 🧹 Clean the condenser: dust on the rear grill increases consumption by 15–20%. It is enough to vacuum it 2 times a year.
• 🔌 Use a voltage stabilizer: surges in the network cause the compressor to wear out. A stabilizer (~3 000 ₽) will extend the life of the refrigerator and reduce consumption by 3–5%.

If you are willing to spend a little money, consider purchasing thermostat with timer (for example, Xiaomi Mijia Smart Plug). It allows:

• 📊 Monitor consumption in real time;
• ⏱️ Turn off the refrigerator for several hours a day (for example, when everyone is at work);
• 📲 Control it through smartphone.

What to do if a Samsung refrigerator begins to consume more

If you notice that your electricity bill has increased for no apparent reason, first check the refrigerator. Here symptoms of increased energy consumption:

• 🔊 The compressor works almost non-stop;
• ❄️ Ice forms on the back wall of the refrigerator compartment;
• 🌡️ The temperature in the chambers does not correspond installed;
• 💰 The electricity bill increased by 200–500 ₽ without changes in consumption.

Causes and solutions:

If the refrigerator is under warranty, do not try to repair it yourself this will deprive you of the right to free service. Contact an authorized service center Samsung (the list is on the official website). Average repair period - 3–7 days.

How to check if the meter is at fault?

Turn off all appliances in the house except the refrigerator. Note how many revolutions the meter disk makes (or how many pulses the indicator flashes) in 15 minutes. Multiply by 4 - get the hourly consumption in kWh. If it is significantly higher than the nominal one, there is a problem. in the refrigerator.

⚠️ Attention: If your refrigerator Samsung was manufactured before 2018, it may use freon R-134a or R-600a. If there is a leak, these substances are not toxic, but require professional refilling!

FAQ: Frequently asked questions about the consumption of Samsung refrigerators

Is it possible to turn off a Samsung refrigerator at night to save money?

Short-term shutdown (for 6-8 hours) is acceptable for modern models with good thermal insulation. However, frequent shutdowns. turning on/off reduces the service life of the compressor. The best option is to use a socket with a timer and turn off the refrigerator only during the daytime (for example, from 8:00 to 17:00), when everyone is at work.

⚠️ Do not turn off refrigerators with a display Family Hub - this may lead to a failure firmware.

Why does the new Samsung refrigerator consume more than indicated in the passport?

The passport indicates laboratory conditions (temperature +25°C, opening the door once an hour). In reality, consumption is affected by:

• Temperature in the room (if). higher +30°C, consumption grows by 20–30%);
• Frequency of door opening (each opening adds 1–3 kWh per month);
• Loading of products (an overloaded refrigerator spends more energy on cooling).

To to get real data, use wattmeter (costs ~1,000 ₽) or a smart socket with an electricity metering function.

Which Samsung model is the most economical in 2026?

According to test results, the best performance y:

1. Samsung RB30A32N0SA (class A+++, 25 kWh/month, volume 301 l);
2. Samsung RL38T671CS8 (class A+++, 24 kWh/month, volume 367 l, No Frost);
3. Samsung RT22HAR4DSA (class A++, 15.8 kWh/month, volume 213 l, ideal for small families).

All these models are equipped with inverter compressors Digital Inverter, which automatically adjust to the load.

Is it worth buying a Samsung refrigerator with the Metal Cooling?

Technology function (metal back wall) speeds up cooling and distributes the temperature more evenly, but increases consumption by Metal Cooling (metal back wall) speeds up cooling and distributes temperature more evenly, but increases consumption by 5–7%Justified if:

• you often. load large volumes of products (for example, after shopping for a week);
• You live in a hot climate (the temperature in the kitchen is higher +28°C);
• Store perishable foods (meat, fish, dairy products).

In other cases, there is no point in overpaying.

How to find out the exact consumption of my Samsung refrigerator?

There are 3 ways:

1. Wattmeter: connect the refrigerator to the device for 24 hours, then multiply the result by 30;
2. Smart socket: models with electricity metering (for example, TP-Link HS110) show consumption in real time;
3. Manual calculation: turn off all appliances in the house, except the refrigerator, and record the meter readings for 1 hour. Multiply by 720 (number of hours in a month).

Please note that in the first 2-3 days after switching on, the refrigerator may consume 20-30% more due to temperature rise.
