What kind of freon is in a Samsung refrigerator: types, markings and refilling

The question of what kind of refrigerant circulates in the cooling system of your refrigeration equipment often arises when repairs or routine maintenance are needed. Equipment owners Samsung face this problem when they notice a decrease in operating efficiency or a complete absence of cold. Modern models of the Korean brand use various types of gases, and choosing the right substance is critical for the safe and long-term operation of the unit.

It is almost impossible to determine the type of refrigerant without opening the technical documentation or inspecting the stickers on the case, since visually the gases R600a and R134a do not differ. An error in choosing freon can lead to compressor failure or even to an explosive situation during installation. In this article we will analyze in detail all aspects of choosing, labeling and refilling refrigerators Samsung.

It is worth noting that the company Samsung Electronics is constantly improving its technologies, moving to more environmentally friendly solutions. This means that old and new models may use completely different operating principles and substances. Understanding these differences will help you correctly formulate a task for a technician or carry out an initial diagnosis of the system yourself.

Main types of refrigerants in Samsung equipment

In the vast majority of household refrigerators made in Korea, two main types of refrigerants are used. The first and most common is isobutane, known in the professional environment as R600a. This substance has excellent refrigeration characteristics and is considered the most environmentally friendly solution today. However, it has one critical feature - high flammability.

The second popular option is tetrafluoroethane, labeled as R134a. This gas does not burn, which makes its use safer from a fire safety point of view, but it is less efficient in heat transfer compared to isobutane. Models on R134a often require more powerful compressors or longer evaporator piping lengths to achieve the same temperature performance.

The choice between these two substances by engineers Samsung is determined by the design of the specific model and the year of manufacture. Early models were often designed for the sake of energy efficiency. Using the wrong gas will upset the pressure balance in the system and lead to overheating of the equipment. R134a, while the modern line has almost completely switched to R600a for the sake of energy efficiency. Using the wrong gas will upset the pressure balance in the system and cause the equipment to overheat.

⚠️ Attention: Never attempt to fill the refrigerator with a type of freon other than that indicated on the nameplate. Mixing gases or replacing R600a with R134a (and vice versa) without completely re-soldering the system and changing the oil in the compressor is strictly prohibited.

In addition, there is a difference in the types of oils used in compressors. For R600a mineral or semi-synthetic oil is usually used, which does not mix well with synthetic analogues for R134a. An attempt to ignore this technical nuance will lead to the formation of plugs in the capillary tube and rapid failure of the compressor unit.

Where to find information about the type of freon

The most reliable way to find out what gas is used in your refrigerator Samsungis by examining the factory information sticker. It is usually located inside the refrigerator compartment on the side wall or on the rear outer wall of the housing, next to the compressor. It is there that the manufacturer indicates all the technical parameters, including the type and amount of refrigerant.

On the sticker you will find a column Refrigerant or Gaswhere the chemical code of the substance will be indicated. The exact mass of the filling in grams is always indicated next to it, for example 130g or 65g. This value is critically important, since modern systems are very sensitive to overdosing or underfilling of gas.

If the sticker is worn off or missing, information can be found in the technical documentation (user manual) that came with the device. Also, the type of refrigerant is often duplicated on a special label attached directly to the compressor or next to it on the frame of the unit.

In some cases, especially when purchasing used equipment, stickers may be lost. In such a situation, you can determine the type of gas by the year of manufacture of the model. Models released after 2010-2012 are 95% likely to be filled with isobutane R600a. Older copies most often worked on R134a or even on freon R12, which is now completely prohibited for use.

Table of compatibility and characteristics of gases

For a better understanding of the differences between the substances used and their impact on the operation of the refrigerator Samsung, consider comparison table. This data will help assess the complexity of maintenance and risks associated with each type of refrigerant.

As can be seen from the table, the transition to R600a allowed to significantly reduce the noise level during compressor operation and reduce energy consumption. However, low operating pressure requires ideal tightness of all connections, since even microscopic leaks lead to airing of the circuit.

Use R12 is currently possible only when restoring very old rare models, since the production of this gas is limited by international agreements. For modern refrigerators Samsung this gas is not used and is not recommended for use due to incompatibility with new sealing materials.

Signs of a leak and the need for refilling

You can understand that the refrigerant level in the refrigerator system Samsung has decreased by a number of indirect signs. The most obvious symptom is insufficient cooling of food or complete defrosting of the chamber while the compressor is running. If the motor hums constantly without turning off, this is a sure sign of loss of circuit tightness.

Another indicator is the appearance of the evaporator. In models with a system No Frost if there is a leak, ice may form unevenly or only in one corner of the freezer. In drip systems ("crying wall"), the back wall ceases to be covered with a uniform layer of frost or moisture during the cooling cycle.

• 🧊 The compressor runs non-stop or turns on too often for short periods of time.
• 🧊 In the freezer, food begins to deteriorate, a soft texture appears frozen meat.
• 🧊 There are no hot spots on the rear radiator grille (condenser), the pipe is cold along its entire length.
• 🧊 The appearance of yellowish oily spots at the leak site (important for soldering or connections).

Important understand that freon is in a working refrigerator Samsung is not consumed. This is a closed system, and if the gas escapes somewhere, it means depressurization has occurred. A simple refueling without finding and eliminating the leak will only give a temporary effect that will last from several days to a couple of months.

⚠️ Attention: If you smell gas in the room where the refrigerator is installed, immediately ventilate the room and do not turn on electrical appliances. Although freon itself is often odorless, odorants are added to R600a to detect leaks, and the oil may have a specific aroma.

The refilling process and the equipment used

Refilling the refrigerator Samsung is a technically complex process that requires specialized equipment and skills. To work, the technician will need a pressure gauge station, a vacuum pump, electronic scales and a supply of the correct refrigerant. Self-refueling “by eye” without scales is unacceptable for modern inverter systems.

The first step is always vacuuming the system. It is necessary to remove not only the remnants of old gas, but also moisture that could get inside during depressurization. The operating time of the vacuum pump depends on the power of the equipment, but is usually at least 20-30 minutes for a high-quality result.

Procedure:
1. Break the filling tube (process).
2. Install the Schrader valve.
3. Connect the vacuum pump.
4. Create a vacuum (up to -1 bar).
5. Refill the calculated amount of freon.

After creating a vacuum, refilling is performed. The amount of gas must strictly correspond to the value on the factory sticker, accurate to the nearest gram. An excess of refrigerant will lead to a sharp increase in pressure and possible rupture of the tubes, and a deficiency will not provide the desired temperature.

Particular attention should be paid to soldering the tubes. When working with refrigerators on R600a it is necessary to first burn out the gas from the system to avoid ignition when using the burner. All work must be carried out in a well-ventilated area or in the open air.

Frequent questions and misconceptions

There are many myths surrounding the topic of refrigerants in refrigerators Samsung . Users often ask whether it is possible to mix different types of freons to save money. The answer is clear: never. Mixing substances with different physical properties will disrupt the operation of the throttling device (capillary tube) and change the boiling point of the mixture, which will disable the equipment.

Another common question concerns the frequency of refueling. Many people think that freon needs to be “added” once a year, like oil in a car. This is an incorrect statement. In a working refrigerator, gas circulates for decades without loss. If refueling is required, it means there is a breakdown that needs to be repaired.

• 🔍 Myth: The refrigerator stopped freezing because "the freon ran out." Reality: The freon cannot run out on its own, it went through a hole.
• 🔍 Myth: You can fill a car air conditioner with freon. Reality: The compositions of oils and additives in automotive and household systems are different.
• 🔍 Myth: The more freon, the better the cold. Reality: Excess gas causes water hammer in the compressor and its breakdown.

It is also worth mentioning the compatibility of oils. If there was mineral oil in the system, and you fill in gas that requires synthetics, separation will occur. The oil will not return to the compressor, which will lead to dry friction and jamming after a short time.

Safety and environmental aspects

Modern environmental requirements dictate their own rules for the production of household appliances. Samsung, like other world leaders, refuses to use substances that destroy the ozone layer. Therefore, in new models you will only find gases that are safe for the atmosphere, although they can be flammable.

When disposing of an old refrigerator Samsung it is important to follow safety rules. You cannot simply throw the unit into a landfill, since freon residues may enter the atmosphere if the housing is damaged. Specialized equipment collection points carry out a safe selection of refrigerant before processing metal and plastic.

It is important for the owner to remember about ventilation. If you are planning to independently repair or dismantle built-in appliances, make sure that the hood is working in the room. Although the gas concentration in one refrigerator is small, in a confined kitchen space it can reach critical values ​​if there is a large leak.

⚠️ Attention: Technical characteristics and types of refrigerants used may vary depending on the region of sale and the year of production of a particular batch. Always check the data on the sticker of your device, and do not rely on information from the Internet for a similar model.

Compliance with operating rules and timely contacting specialists at the first sign of a malfunction will allow your refrigerator Samsung to serve for many years without the need for complex and expensive system repairs cooling.
