Inverter refrigerator: types, features, pros and cons + TOP 15 best models
The basic design of a refrigerator has not changed for more than 100 years.It also consists of a compressor, a refrigeration chamber and a system of pipes through which the refrigerant moves.
The improvement of refrigerators is constantly moving towards their quietness and energy efficiency. In recent years, the inverter refrigerator has become popular, which meets all the parameters of the evolutionary trend.
What is this equipment and what are its advantages? We will examine these questions in detail in our article. We will also talk about the principle of operation of a compressor with an inverter and discuss the best manufacturers of such refrigerators.
To make choosing easier, we have prepared a rating of popular models. The list includes refrigerators of various modifications with good operating parameters that have won many positive user reviews.

Types of compressors for refrigerators
An electric compressor is designed to compress a chemical refrigerant and then transfer it to the condenser.
To ensure gas pumping, two different devices are used:
- electric motor;
- electromagnetic coil.
Each type of compressor has pros and cons.
Modern refrigerators primarily use an electric motor as a drive, but this does not mean that the electromagnetic coil is less efficient.
Based on their operating principle, refrigeration compressors are divided into:
- Piston. A common option, most often used in the design of refrigerators produced in the CIS. The main structural elements are a pair of metal cylinders that move vertically or horizontally according to a reciprocating principle. They move thanks to a crank system.
- Linear. The piston in them does not have a connecting rod mechanism and moves due to the operation of an electromagnetic coil exclusively in one plane. The work is carried out in three stages: turn on, cool, turn off. Due to frequent switching on, power consumption increases slightly, although it is almost two times lower than in traditional piston ones. This type is mainly used in Electrolux units.
- Screw. They are rotary. These devices do not have a piston, and the difference in pressure parameters in them is achieved due to the rotation of the rotor and the moving plate. Such devices are used mainly in Indesit brand units.
Modern refrigerators mainly use rotary compressors, although LG offers customers a wide range of linear compressors. The manufacturer managed to maintain their advantages while eliminating most of the design flaws.
According to the temporary operating principle, compressors can be divided into two types:
- inverter operating continuously;
- stepped, which are periodically turned on and off using a relay.
The first principle of operation has long been used in household appliances, for example, in air conditioners. Its features make it possible to achieve greater energy efficiency and less noise in equipment, but the high cost of the equipment does not allow this technology to be made truly widespread.
Inverter models differ from their linear counterparts in that they operate continuously, i.e. do not waste energy on on/off processes. After activation, they maintain the specified operating mode required to preserve products. Refrigerators equipped with them are more expensive than conventional ones, but significantly more economical to operate and more reliable.
Leading models of South Korean units with LG and Samsung logos are equipped with inverton compressors.
Operating principle of an inverter compressor
To maintain a constant temperature in the refrigerator, its compressor requires constant operation. However, electric motors operating at full power heat up quickly and may fail.
Therefore, conventional compressors operate rhythmically, switching on and off periodically.
Their work cycle can be represented as follows:
- When you turn on the refrigerator for the first time, a signal about a high internal temperature is transmitted from the temperature sensor to the electric relay. It starts the compressor at full power and initiates the cooling process.
- When the temperature drops to the programmed level, the refrigerator turns off. The compression element motor also stops working.
- When the temperature inside the refrigerator subsequently increases, the relay starts its operation again. The cycle repeats.
To prevent the temperature sensor from triggering frequently, it is adjusted to the operating interval. For example, the refrigerator starts at a temperature of +5 °C, and shuts down at +2 °C.
This principle allows you to avoid frequent voltage drops in the house when starting the engine, which negatively affect the operation of other household appliances. By the way, if you regularly experience voltage problems, you shouldn’t wait until electrical appliances break down. It’s better to choose the right one right away stabilizer for home.
An inverter compressor has a slightly different operating method. Its design feature is the presence of a built-in inverter - a device that converts alternating current into direct current, and then vice versa.
Such actions allow you to achieve arbitrary parameters of the voltage and frequency of electricity that is supplied to the motor or coil.
By adjusting the current characteristics, linear control of the compressor operation is achieved, and the compressor itself never turns off completely. Only the rotational speed of the electric motor or the speed of the piston changes.
As a result, cooling gradually increases or decreases, adjusting the temperature inside the refrigerator to the programmed level.
The inverter operating principle allows you to maintain the temperature at the same level, eliminating its fluctuations in the range. This is especially important for a zero-temperature chamber, where a difference of 1 degree can significantly affect the quality of stored products.
Thus, the inverter prevents the compressor from working at maximum load, providing less noise, saving energy and protecting it from breakdowns.
Which brand is better?
Modern inverter compressors require quite a lot of research to evaluate the quality and durability of their work. Therefore, few manufacturers can boast of a wide range of such equipment.
The largest number of them are produced by the following companies, listed in decreasing order of the number of models presented on the market:
Refrigerators with this type of compressor are also produced by other equipment manufacturers, but their total market share is less than 3%. Their products often use a third-party compressible device that has proven reliability.
Inverter equipment with several insulated chambers can be equipped with two compressors, each of which provides temperature control in a certain part of the internal space.
This design simplifies the dynamic distribution of cold between the constantly opening refrigerator compartment and the predominantly closed freezer compartment.
It should be borne in mind that the price of a compressor is about half the cost of the equipment, so duplicating it significantly increases the cost of purchasing a refrigerator.
Most inverter devices on the market are rotary. And only LG has developed a linear one, which is based on a piston driven by an electromagnetic coil and springs.
The warranty on this compressor is 10 years. That is, the company guarantees that its internal parts will continuously move throughout this period without breakdown.

Advantages and disadvantages of such a solution
Refrigeration units with a continuous compressor operating principle are gradually capturing the market with their beneficial qualities. However, their shortcomings hinder the final transition of manufacturers to the production of equipment of this type.
If inverter compression devices did not have a lot of competitive advantages, then manufacturers would not have built them into top models of refrigerators.
The main advantages of these devices include:
- Economical. This technique consumes up to 35% less electricity than analogues with a stepped operating principle. This allows buyers to recoup some of the money spent on their purchase over time.
- Long service life. Almost all manufacturers guarantee trouble-free operation of the inverter compressor for at least 10 years. If it breaks, it will be replaced with a new one free of charge.
- Low noise. In small houses and studio apartments, nighttime operation of the electromechanical relay in conventional refrigerators can interfere with sleep. The operation of inverter compressors is regulated silently and smoothly.
- Temperature stability. A constant temperature regime inside the equipment chambers allows you to increase the maximum shelf life of products and maintain their beautiful appearance.
- Safety. When starting the compressor, the current can be 5-7 times higher than the operating value, which leads to a short-term voltage drop throughout the house. In inverter equipment, this effect occurs only the first time it is turned on, which makes it safe for surrounding household appliances.
Samsung and LG have completely switched to producing new models of refrigerators with modern compressors that operate continuously. They set the general trend in the industry, forcing competitors to also switch to the production of more advanced equipment.
An additional incentive for companies to switch to the production of this type of equipment is the tightening of international requirements for the energy efficiency of household appliances.
These rules benefit consumers by allowing them to pay less for electricity.We have provided more information about refrigerator energy consumption and ways to save in next article.
After inverter technology entered mass production, users were able to evaluate not only its advantages, but also its disadvantages.
Its disadvantages include:
- high cost;
- sensitivity to power supply parameters.
Compressors with continuous operation include additional electronic components responsible for voltage and frequency conversion. Therefore, the cost of refrigerators with them is at least 30-50% higher.
If we compare models with a volume of 250-300 liters, then the inclusion of an inverter element in the design adds $150-200 to the price. The maximum energy savings in this case will be 10 kW per month.
With an electricity cost of $1/kW, the inverter will pay for itself in 12-18 years, which casts doubt on the economic feasibility of its purchase. However, this equipment also has a number of other advantages that make it worth buying.
The sensitivity of inverter compressors to voltage surges, frequency and sine waves also leads to additional costs.
To ensure the normal operation of such equipment, especially in private homes, it may be necessary to purchase Voltage regulator or UPS.You can connect not only a refrigerator to it, but also other devices that are demanding on the electrical network parameters.
Thus, all the disadvantages of continuous operation compressors come down to additional financial costs. But if this issue is not fundamental, then it is recommended to purchase a refrigerator with just such equipment inside.

The inverter principle is increasingly used in the operation of household appliances. Equipment based on it is included in air conditioners, refrigerators, and UPS.
Due to the wide possibilities for regulating the current coming out of the inverter, it is possible to reduce the load on equipment and ensure energy savings. Therefore, buying an inverter refrigerator will soon become no alternative, which will only benefit consumers.

I had the opportunity to compare the operation of a conventional refrigerator and an inverter. What can I say: the inverter is really quieter. But not so much that it’s worth replacing the refrigerator because of it.This is appropriate if you have a refrigerator from the year 2000, they are much noisier. And since they are sensitive to power fluctuations, they are not suitable for us at all, since the voltage in the network is often and heavily unstable.
I’ve heard about inverter split systems and even encountered them, but not about inverter refrigerators. In theory, the principle of operation is the same. But I’m not a supporter of this type of refrigerator, why overpay. Again, electricity is a controversial issue. Payback period is 12-18 years, usually during this time I buy a new refrigerator. I agree 100% that it works quieter. But regarding the safety of products and a temperature difference of 1 degree, this is not significant for me. I don’t keep food in my refrigerator long enough for it to spoil.
I’ve been thinking about buying such a refrigerator for a long time now and haven’t decided to buy it. At home, most importantly, I have already installed inventory air conditioners. I also want an inventory refrigerator, but a mechanic I know is trying to dissuade me. They seem to constantly break down, more often than regular ones, and the parts are expensive and need to be ordered. Among the inventory companies, I like Samsung and Bosch.
I'm wondering how durable these inverter refrigerators are? The 10 years described above will last most conventional refrigerators.
Hello. 10 years is not about the end of the life of the refrigerator, but about the majority of cases in which repairs to an appliance with such a compressor were not required. The load on the compressor is much lower than in conventional refrigerators, which means the service life is longer.
My grandmother’s Minsk refrigerator has been running for 40 years and has never been repaired.
I would not say that inverter refrigerators are reliable, as they say on the Internet; rather, on the contrary, they often break down. The Internet is full of videos about repairing inverter refrigerators, where compressors and control boards most often fail. You can ask any specialist, not one of them will recommend purchasing such a refrigerator. But unfortunately there is no choice left if you want a sophisticated refrigerator - these are the only inverter ones.
The worst thing about these refrigerators is the noise. Low frequency hum, like a transformer box. I read reviews on the Internet, it turns out this is all the time. I regret that I bought a fancy refrigerator with an inverter. People, don’t believe the advertising, there is nothing good about an inverter refrigerator.
I'm confused by the constant running of the compressor. Doesn't this mean that the compressor will constantly be "erased"? An ordinary refrigerator turns on once every half hour, but this one will constantly spin.
Good afternoon
Question for experts: 1) whose (what) linear inverter compressors Atlant uses, 2) linear inverter compressors using the electromagnet principle are not sensitive to the quality of the electrical network, that is, they are more reliable than collector ones - as statistics for Atlant specifically in this segment. I'm considering purchasing. Thank you
What do you recommend in my case:
The linear inverter compressor on the LG GR P247JHLE refrigerator does not work - this model of compressor is no longer on sale - is it possible to find an analogue?
I found some confusion in the article.The Liebherr CN 4813 refrigerator is not inverter with a consumption of about 245 kW/year. Inverter CP 4813 with a consumption of 191 kW/year. Class A+++. The first with know frost, the second without.
The inverter can enter a mode close to the resonance of the compressor and successfully hum. What does it have to do with it all the time?
