Inverter refrigerator: types, features, pros and cons + TOP-15 of the best models
For more than 100 years, the circuit diagram of the refrigerator has not changed. It also consists of a compressor, a refrigerator, and a system of tubes through which refrigerant moves.
Improvement of refrigerators is constantly moving towards their low noise and energy efficiency. In recent years, an inverter refrigerator has become popular, which meets all the parameters of the evolutionary trend.
What is such equipment and what are its advantages? We will analyze these issues in detail in our article. We will also talk about the principle of compressor operation with an inverter and discuss the best manufacturers of such refrigerators.
To facilitate the task of choice, we have prepared a rating of popular models. The list contains refrigerators of various modifications with good operating parameters, which have won many positive user reviews.

Varieties of compressors for the refrigerator
An electric compressor is designed to compress a chemical refrigerant and then transfer it to a condenser.
To ensure gas transfer, two different devices are used:
- electric motor;
- electromagnetic coil.
Each type of compressor has its pros and cons.
In modern refrigerators, an electric motor is mainly used as a drive, but this does not mean that the electromagnetic coil is less efficient.
According to the principle of action, refrigeration compressors are divided into:
- Piston A common option used most often in the device of refrigerators manufactured in the CIS. The main structural elements are a pair of metal cylinders moving vertically or horizontally according to the reciprocating principle. They move thanks to the crank system.
- Linear. The piston in them does not have a connecting rod mechanism and moves due to the operation of the electromagnetic coil exclusively in one plane. The work is carried out in three stages: turn on, cool, turn off. Due to frequent switching on, the electric power consumption is slightly increased, although it is almost two times lower than in traditional reciprocating ones. This type is used in the main units of Electrolux.
- Screw. They are rotary. These devices do not have a piston, and the difference in the pressure parameters in them is achieved due to the rotation of the rotor and the moving plate. Such devices are mainly used in Indesit units.
Modern refrigerators mainly use rotary compressors, although LG offers its 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 principle of operation, compressors can be divided into two types:
- inverter operating continuously;
- step, which periodically turn on and off with the help of relays.
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 lower noise technology, but the high cost of equipment does not allow to make this technology really massive.
Inverter models from linear counterparts differ in that they operate continuously, i.e. Do not spend energy on on / off processes. After activation, they maintain the specified operating mode required to save the products. The refrigerators equipped with them are more expensive than usual, but significantly more economical in operation and more reliable.
Inverting compressors are equipped with leading models of South Korean units with the LG and Samsung logos.
Inverter compressor working principle
To maintain a constant temperature in the refrigerator requires constant operation of its compressor. However, electric motors operating at full power quickly heat up and can fail.
Therefore, conventional compressors operate rhythmically, periodically turning on and off.
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 on 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 motor of the compression element also ceases to work.
- With a subsequent increase in temperature inside the refrigerator, the relay starts its operation again. The cycle repeats.
So that the temperature sensor often does not work, it is adjusted to the operating interval. For example, the refrigerator starts up at a temperature of +5 ° C, and turns off at +2 ° C.
This principle allows you to avoid when starting the engine frequent voltage drops in the house, which adversely affect the work of the rest of household appliances. By the way, if you regularly experience voltage problems, you should not wait until electrical appliances break down. It’s better to choose the right one right away. stabilizer for home.
The inverter compressor has a slightly different method of operation.Its design feature is the presence of a built-in inverter - a device that converts alternating current to direct, and then vice versa.
Such actions allow you to achieve arbitrary parameters of the voltage and frequency of the electricity that is supplied to the motor or coil.
By adjusting the characteristics of the current, linear control of the compressor is achieved, and it never switches off completely. Only the speed of the electric motor or the speed of the piston changes.
As a result, cold formation gradually increases or decreases, adjusting the temperature inside the refrigerator to the programmed level.
The invertor principle of operation allows maintaining the temperature regime at the same level, excluding its fluctuations in the range. This is especially important for a camera with zero temperature, where a difference of 1 degree can significantly affect the quality of the stored products.
Thus, the inverter protects the compressor from operating at maximum load, providing less noise, saving energy and protecting it from breakdowns.
Which brand is better to choose?
Modern inverter compressors require quite lengthy studies to assess the quality and durability of their work. Therefore, few manufacturers can boast a wide range of such equipment.
The largest number of them is produced by the following companies, listed in decreasing order of the number of models on the market:
Other manufacturers of equipment also produce refrigerators with this type of compressor, but their total market share is less than 3%. Their products often use a compressible device from third-party companies that have already proven their reliability.
Inverter equipment with several isolated chambers can be equipped with two compressors, each of which provides temperature conditions in a certain part of the internal space.
This design makes it possible to simplify the dynamic distribution of cold between a constantly opening refrigerating compartment and a predominantly closed freezer.
It should be borne in mind that the price of a compressor is about half the cost of equipment, so its duplication significantly increases the cost of buying a refrigerator.
Most inverter devices on the market are rotary. And only LG has developed a linear, based on a piston driven by an electromagnetic coil and springs.
The warranty for such a compressor is 10 years. That is, the company guarantees that its internal parts will continuously move all this period without breakage.

Advantages and disadvantages of such a solution
Refrigeration units with a continuous principle of compressor operation are gradually capturing the market with their useful qualities. However, their shortcomings hinder the final transition of manufacturers to the manufacture of equipment of this type.
If invertor squeezing devices did not have a mass of competitive advantages, then manufacturers would not integrate them into the top models of refrigerators.
The main advantages of these devices include:
- Cost-effectiveness. Such a technique consumes up to 35% less electricity than analogues with a stepwise principle of operation. This allows customers to compensate for part of the money spent on the purchase over time.
- Long service life. Almost all manufacturers guarantee a trouble-free operation of the inverter compressor for at least 10 years. In the event of a breakdown, it will be replaced with a new one for free.
- Low noise. In small houses and studio apartments, night-time triggering of an electromechanical relay in conventional refrigerators can interfere with sleep. The work of inverter compressors is regulated silently and smoothly.
- Temperature stability. The constant temperature regime inside the equipment chambers allows increasing the maximum shelf life of products and preserving their beautiful appearance.
- Safety. When the compressor starts, 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 at the first start-up, which makes it safe for surrounding household appliances.
Samsung and LG have completely switched to the release of new models of refrigerators with modern compressors that operate continuously. It is they who 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 to tighten international requirements for energy efficiency of household appliances.
These rules play into the hands of consumers, allowing them to pay less for electricity. More information about the refrigerator’s energy consumption and how to save it is provided in next article.
After the inverter technology went into mass production, users were able to evaluate not only its advantages, but also its disadvantages.
Its minuses include:
- high cost;
- sensitivity to power supply parameters.
Compressors with continuous operation incorporate additional electronic components responsible for converting voltage and frequency. Therefore, the cost of refrigerators with them is at least 30-50% higher.
If we compare models with a volume of 250-300 liters, the inclusion of an inverter element in the design adds to the price of 150-200 dollars. The maximum energy savings in this case will be 10 kW per month.
With an electric power cost of $ 1 / kW, the inverter will pay off in 12-18 years, which makes one doubt the economic feasibility of buying it. However, this equipment has several other advantages, because of which it is worth buying.
The sensitivity of inverter compressors to power surges, frequency and sinusoid also leads to additional costs.
To ensure the normal operation of such equipment, especially in private homes, you may need to buy Voltage regulator or UPS. You can connect not only a refrigerator to it, but also other devices that are demanding on the parameters of the mains.
Thus, all the disadvantages of continuous operation compressors are reduced to additional financial costs. But if this issue is not fundamental, then it is recommended to purchase a refrigerator with such equipment inside.

I had the opportunity to compare the operation of a conventional refrigerator and an inverter. What can I say: the inverter works really quieter. But not so much that because of this it is worth changing the refrigerator. This is appropriate if you have a refrigerator of the year 2000, so they work much more noisily. And since they are sensitive to power fluctuations, they do not suit us at all, since the voltage in the network is often and densely unstable.
I heard and even came across such inverter split systems, but I don’t know about inverter refrigerators. In principle, the principle of operation is the same. But I am not a supporter of this type of refrigerator, why overpay. Again, a moot point about electricity. Payback 12-18 years, usually during this time I buy a new refrigerator. What works quieter, it agrees 100%. But about the safety of products and the temperature difference of 1 degree, for me it is not essential. The products in my refrigerator have not been stored for so long that they have deteriorated.
I’ve been thinking about buying such a refrigerator for a long time and can’t decide on a purchase. At home, most importantly, I have installed inventory air conditioners. The refrigerator also wants inventory, but a familiar master is trying to dissuade. It seems that they constantly fail, more often than usual, and the parts are expensive and must be ordered. Of the inventory like the company Samsung and Bosch.
I am interested in how durable these inverter refrigerators are? 10 years, which are described above, will work and most ordinary refrigerators.
Hello. 10 years - this is not about the end of the life of the refrigerator, but most of the cases in which repair with a compressor with such a compressor was not required. The load on the compressor is much lower than in conventional refrigerators, which means that the service life is longer.
My grandmother’s Minsk refrigerator has been working for 40 years, 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. The Internet is full of videos about the repair of inverter refrigerators, in which compressors and control boards most often fail. You can ask any master, none of them will advise you to buy such a refrigerator. But unfortunately there is no choice if you want a fancy fridge - these are only inverter ones.
