When choosing a new refrigerator or repairing an old one, many are faced with the question: what refrigerant is used in it? Not only the cooling efficiency, but also health safety, environmental friendliness and even the cost of maintenance depend on the type of freon. In 2026, manufacturers almost completely abandoned obsolete refrigerants in favor of modern solutions - but which ones exactly?
Even 10 years ago, 90% of refrigerators used R134a, but today it is being actively replaced by R600a (isobutane) and R290 (propane). Why this change occurred, what are the pros and cons of each option, and how to determine the type of freon in your refrigerator - we will look in detail.
Important: information about refrigerants is relevant for household refrigerators Samsung, LG, Indesit, Atlant, Beko and other popular brands. For industrial and medical models, other standards may be applied.
Evolution of refrigerants: from banned freons to eco-solutions
Until 2010, chlorofluorocarbons (CFC) were widely used in refrigerators - for example, R12. They were cheap and effective, but they destroyed the ozone layer. After the signing of the Montreal Protocol (1987), these substances were banned and replaced with hydrofluorocarbons (HFC) — R134a and R404A.
However, problems were also discovered: high global warming potential ( R134a problems were discovered: high global warming potential (GWP = 1430). 2020, the EU began a phase-out of it in household appliances. Today, priority is given to natural refrigerants:
- 🔥 R600a (isobutane) - most common in refrigerators 2023-2026
- 🌿 R290 (propane) —more environmentally friendly, but flammable (used in premium models).
- ❄️ R134a —also found in budget and older models.
The transition to natural refrigerants is dictated not only by environmental standards, but also by savings: isobutane (R600a) is 15–20% more efficient than R134a with the same energy consumption. However, it has nuances - more on that below.
R600a (isobutane): why is it the market leader?
R600a is isobutane, a hydrocarbon refrigerant with zero ODP (ozone depletion potential) and minimal GWP (3). Its main advantages:
- ⚡ Energy efficiency: R600a refrigerators consume 10–15% less electricity.
- 🌍 Environmentally friendly: does not harm the ozone layer and the climate.
- 💰 Low cost of refueling: cheaper than R134a by 1.5–2 times.
- 🔧 Compatibility: works with most modern compressors.
However, isobutane has two critical disadvantages:
- Flammability: R600a ignites at a concentration in the air of 1.3%. In domestic conditions, this is unlikely (there is only 50-150 grams of it in the refrigerator), but in the event of a leak it is required. ventilation.
- Sensitivity to moisture: when water gets into the system, an ice plug is formed, which can damage the compressor.
Manufacturers solve the problem of flammability through:
- 🔒 Sealed systems with an ultra-low probability of leakage.
- 🛡️ Leak sensors in premium models (for example, Liebherr Premium).
- 📄 Certification according to the standard IEC 60335-2-24that guarantees safety.
R134a: outdated, but still alive
R134a (tetrafluoroethane) is a refrigerant of the previous generation, but it is still used in:
- 💵 Budget refrigerators (for example, Birusa, Snaige).
- 🏥 Medical equipment (due to low flammability).
- 🚗 Automotive air conditioners (until 2026).
Advantages of R134a:
- ✅ Non-flammable and non-toxic.
- ✅ Cheaper than natural refrigerants when refilled (but more expensive to operate due to high energy consumption).
- ✅ Compatible with old compressors.
Disadvantages:
- ⚠️ GWP = 1430 (harmful to the climate).
- ⚠️ Less efficient: a refrigerator using R134a spends 10–20% more electricity.
- ⚠️ Banned in the EU for new household appliances from 2026 (there are no restrictions in Russia yet).
Why has R134a not been banned in Russia yet?
Russia has less stringent environmental standards than the EU. In addition, many factories (for example, Pozis in Kirov) are still producing refrigerators with R134a for the domestic market and the CIS countries. A complete abandonment of it is not expected before. 2030.
R290 (propane): an eco-friendly alternative for the premium segment
R290 is propane, another natural refrigerant with GWP = 3It is even more environmentally friendly than R600a, but has its own characteristics:
- 🔥 High flammability: ignites at a concentration of 2.1% (versus 1.3% for isobutane).
- 💎 Used in premium refrigerators (Liebherr, Miele, Smeg).
- ⚡ 5–10% more efficient than R600a energy consumption.
Due to the flammability, R290 requires:
- 🛡️ Enhanced circuit protection (double walls of tubes).
- 🔧 Special equipment for refueling (not every master takes on the job).
- 📜 Certifications according to the standard EN 378.
In Russia, R290 refrigerators are still rare - their share does not exceed 5% of the market. The main buyers: eco-activists and owners of country houses with autonomous power supply (due to low energy consumption).
How to determine the refrigerant in yours. refrigerator?
There are 5 reliable ways to find out the type of freon:
- The sticker on the compressor: usually the refrigerant is indicated there (for example,
Refrigerant: R600aThe compressor is located at the bottom of the refrigerator. - Technical data sheet: Under "Specifications" or "Refrigerant".
- Refrigerator model: some brands encode the type of freon in the name. For example, Atlant models with
HMat the end work on. R600a. - Compatibility table (see below).
- Consultation with a specialist: if the refrigerator is old or the documentation is lost, call a specialist with leak detector.
☑️ How to find information about the refrigerant
If the sticker is worn off and there is no passport, focus on the year of manufacture:
- 📅 Before 2010 —most likely
R12orR134a. - 📅 2010–2020 —
R134aorR600a. - 📅 After 2020 —
R600a(80% of cases) orR290(premium).
Table: Compatibility of refrigerants and refrigerator models
| Brand | Series/Model | Refrigerant | Features |
|---|---|---|---|
| Atlant | HM, MHM | R600a | All models since 2015 |
| Samsung | RB, RS (2020–2026) | R600a | Exception: medical refrigerators on R134a |
| LG | GA, GB (Inverter Linear) | R600a | Models with linear compressor |
| Liebherr | Premium, BioFresh | R290 or R600a | R290 only in models marked "Green" |
| Indesit, Ariston | BAA, BIA (2018–2026) | R600a | Budget models can be on R134a |
⚠️ Attention: If your refrigerator was manufactured before 2010, there is a high probability that it R12 is a refrigerant prohibited for production. Refilling it is possible only after replacing the compressor and oil with ones compatible with modern freons.
Is it possible to replace the refrigerant in the refrigerator?
Technically you can replace freon, but this is not always advisable. Here are the key points:
- 🔄 R134a → R600a: Possible, but requires:
- Flushing the system (old oil is incompatible with isobutane).
- Replacing the filter drier.
- Tightness checks (R600a is more fluid).
- ❌ R12 → R600a/R290: Impossible without replacing the compressor and oil.
- ⚠️ R600a → R290: Impractical - both are natural, the difference in efficiency is minimal.
Cost of replacing the refrigerant:
- 💵 R134a → R600a: 5,000–8,000 RUR (with labor and materials).
- 💵 R12 → R134a: 3,000–5,000 RUR (temporary solution, since R134a is also becoming obsolete).
- 💵 R134a → R290: 10,000–15,000 ₽ (due to the high cost of propane and labor).
⚠️ Attention: Replacing freon yourself is dangerous! Isobutane and propane are flammable, and incorrect filling can lead to compressor failure. Entrust the work only to certified craftsmen with equipment for vacuuming the system.
FAQ: Frequently asked questions about refrigerants in refrigerators
❓ Which refrigerant is the safest for the home?
From a safety point of view, the best option — R134a (non-flammable), but it is becoming obsolete. Among modern refrigerants R600a it is safe when used correctly: its amount in the refrigerator is minimal (50–150 g), and the system is sealed. The risk of ignition occurs only in the event of a major leak (for example, if the pipes are damaged during repairs).
❓ Is it possible to fill the refrigerator with freon yourself?
No. For refilling you need:
- Vacuum pump (to remove moisture).
- Gauge manifold.
- Cylinder with refrigerant and oil.
- Leak detector.
Errors during refueling will lead to compressor failure or freon leakage. In addition, isobutane and propane are flammable - working with them requires certification.
❓ Why does the new R600a refrigerator consume less electricity?
Isobutane (R600a) has a higher heat transfer coefficient than R134a. This means that the compressor needs to work less to cool to the same temperature. In addition, R600a is better compatible with inverter compressors, which themselves are more energy efficient than traditional ones.
❓ What to do if there is a freon leak in the refrigerator?
Signs of a leak:
- The refrigerator does not cool, but the light inside is on.
- The compressor works without stopping.
- There are oily stains on the back wall (if R600a is leaking).
Actions:
- Disconnect the refrigerator from the network.
- Ventilate the room (if the refrigerant flammable).
- Do not turn on the refrigerator - this can burn the compressor.
- Call a technician for diagnostics and refilling.
❓ Is freon from the refrigerator harmful to health?
Refrigerants in household quantities safe. Danger arises only when:
- Mass leakage in a small room (for example, R600a in a volume of >150 g in a kitchen of 10 m²).
- Freon gets into an open fire (risk only for R600a and R290).
- Direct inhalation of gas (for example, during repairs without protection).
Modern refrigerators are designed so that even with a complete leak, the concentration of freon in the air remains below a dangerous level.
