LG refrigerators with inverter compressor. Top best offers

LG refrigerators with an inverter compressor are household appliances that smoothly regulate engine speed and thus maintain a constant temperature in the chambers of the refrigeration unit. Also, this technology can significantly reduce the operating noise of a household appliance and reduce energy consumption.

The operation of the inverter compressor occurs smoothly, without sudden switching on and off. When it starts working, it initially cools the chamber inside the refrigerator to the desired (set) temperature, which it subsequently maintains constantly. That is, this type of engine does not turn off completely, but only reduces the speed to a minimum. As a result, the temperature in the chamber remains unchanged, which is a definite plus. Our review will tell you which LG refrigerator with an inverter compressor will be a definite plus directly in your kitchen space.

Differences between an inverter compressor and a conventional one

Regardless of the type of refrigerator compressor, they are all divided into two categories - conventional and inverter. Conventional compressors are also called non-inverter, start-stop or On/Off. Below is a description of how conventional and inverter compressors work in refrigerators.

How does a regular compressor work?

Equipment equipped with a conventional compressor functions as follows:

The compressor turns on and runs until the temperature in the refrigerator reaches the desired value;
After the chamber has cooled, the compressor is turned off;
The temperature in the compartment gradually drops due to heat loss;
When the sensor detects a decrease in temperature by 1-2 degrees, the compressor turns on again.

A conventional compressor always runs at the same speed , regardless of type. Cooling only occurs when it is turned on. The speed of the refrigerator compressor motor is not regulated in any way; it either works or it doesn’t.

Operating principle of an inverter compressor

Refrigerators with an inverter compressor work differently:

The compressor turns on and operates at full power until the compartment cools down to the set temperature;
After this cooling, it does not stop, but reduces the operating speed to a minimum, maintaining the temperature regime;
If the temperature in the chamber rises sharply (if the door is open or you put something heated in the refrigerator), the operating speed increases;
More intensive cooling occurs; when the desired temperature is reached, the compressor again operates at minimum power.

The inverter compressor runs constantly, but its operating speed may vary . The more the temperature in the chamber differs from the norm, the more intensely it works. Accordingly, the refrigerator cools the chamber faster.

The principle of operation of an inverter compressor in an LG refrigerator

That is why refrigerators began to be called inverter, since this is the principle of operation of the compressor, that is, the main power unit, which is found in any device of this type.

Their operation differs from the operation of linear compressors in that they can change the engine speed. That is, the device allows a smooth transition from one operating mode to another.

Linear compressors are started at their maximum power. Automatic shutdown occurs as soon as the refrigerator reaches the set temperature. The relay regulates operating processes that are associated with starting and stopping.

It is inherent for this element to create an accompanying sound at the moment of operation. It is very similar to a click. When the engine is running, it creates sounds and noises that can be clearly heard by others.

IMPORTANT! Please note that such compressors are also used in the manufacture of computer and medical equipment, as well as in the automotive industry and in the production of measuring instruments.

Constantly starting the engine at full power, alternating with stops, leads to the compressor overheating. And soon the refrigerator will fail. In addition, when the engine is turned on every time, this leads to an increase in the load on the electrical network. There are unnecessary energy costs. It's not economical.

IMPORTANT! The solution that can optimize the efficiency and duration of operation of cooling devices is an invention that has become an alternative to outdated devices. In this case, we are talking about inverter models.

What is the principle of operation:

the compressor turns on;
during operation it cools the inner chamber;
the inverter’s action is aimed at maintaining the specified temperature in the chamber;
With such a system, the compressor, when it temporarily slows down, does not turn off completely.

The operation of the device is smooth. In order to show the difference in the operation of linear and inverter compressors, a comparison can be made with how a car engine works. An inverter is a car moving along a perfectly flat road. And a linear compressor means moving along a dirt road. And it's uneven. It has steep ascents and descents.

If we take the improved models, then brushless, three-phase motors are used in them. They are also used in the manufacture of modern equipment. Both measuring and medical. And also in the production of modern engineering developments.

What is the essence of the work of inverter compressors? Using the control unit of the device, alternating current is converted into direct current. And then the current changes again to an alternating form. But it already has a different frequency, which is necessary in this case.

IMPORTANT! This process is called inversion, that is, it is a change. The transformation that is carried out makes it possible to adjust the output parameters of any load with great accuracy. Including the compressor.

According to those who produce such equipment, the inversion principle makes it possible to make energy costs more economical. Stable operation of the compressor, when precise output parameters are set, allows for temperature control inside refrigeration and freezer chambers with great accuracy and speed.

Inverter refrigerator compressor: pros and cons

Any technology has its positive and negative sides. Also, inverter refrigerator compressors have their pros and cons. To describe briefly , some of the advantages of inverter models are:

Low noise level;
There is no heavy load on the power grid;
Cost efficiency up to 50%;
Long service life;
Precise temperature maintenance in the refrigerator.

The disadvantages include:

High price;
Sensitivity to power surges;
High cost of diagnostics and repairs;
Problems with the availability of replacement when necessary;
Lack of qualified craftsmen.

In this section we will analyze in detail all the pros and cons of refrigeration compressors . If you want to learn more about their types, this is written below.

pros

#1 – Low noise level

In reality, this is a controversial point. Inverter linear compressors are no quieter than conventional ones . The only difference is that they can make clicking noises when turned on. Their noise level is the same as that of screw and spiral ones. Inverter piston compressors are somewhat louder than linear inverter compressors, but quieter than conventional piston ones.

The differences are noticeable when compared with conventional piston compressors. Especially when comparing old and new models. A piston compressor vibrates more strongly, and the vibration is transferred to the housing. Often there is a buzzing, rustling, and sometimes creaking sound.

Advice

If your refrigerator with an inverter compressor is loud, look down the back wall. The transport bolts may not have been unscrewed. Although the compressor itself operates silently, if it is tightly connected to the housing, the slightest vibration can lead to resonance and extraneous sounds will appear.

No. 2 – Network load

A non-inverter type compressor, when turned on, puts a large load on the network because it operates at full capacity. In addition, it has a starting current that is 2-4 times higher than the rated power . When turned on, it places a heavy load on the electrical wiring. Because of this, voltage may jump and automatic protective equipment in the network or electrical appliances may be triggered.

The inverter compressor works without shutting down. It puts a constant but small load on the power grid. It has no starting currents, so there is no risk of damaging protective automation or electrical appliances.

Starting current – represents the current that is required to start an electrical or electrical device. It is several times greater than the rated current, which is why it is so important to take this parameter into account when selecting equipment.

No. 3 – Energy consumption

Inverter compressors consume less electricity than linear and piston compressors. This is achieved due to the absence of on-off cycles. The absence of starting currents is also a saving factor.

When a conventional compressor starts working (immediately at full power), it has to overcome the freon resistance. After all, when the compressor is turned off, the refrigerant does not circulate through the system. To accelerate to the required speed, you have to resume the flow, and this means additional energy consumption.

Conventional piston compressors have refrigeration oil in the lower part (similar to automobile oil, but different in composition and properties). When idle, it cools and its viscosity increases. During startup, the compressor also has to overcome its resistance.

An inverter compressor constantly pumps refrigerant through the circuit. Only the speed will change slightly, depending on the temperature in the refrigerator chambers. He does not need to waste electricity and time on “overclocking”. The oil in a piston inverter compressor cools slightly and remains fluid. Tests have shown that the linear inverter compressor:

More economical than linear by 10-15%;
More economical than an inverter piston by 20-30%.
More economical than piston by 30-50%.

No. 4 – Wear

The compressor piston and valves are subject to the most wear. Strong production of metal occurs at the moment of start-up. Since the inverter compressor works without stopping, its parts wear out less. Accordingly, it has a longer service life.

Important

Many people say: “My old non-inverter ZIL refrigerator worked for 30 years and everything is fine, but the new inverter compressor broke down in the 10th year.” The problem is not that conventional compressors last longer. These are the features of current manufacturers.

Any technology nowadays is produced in such a way that it is periodically updated. Therefore, the service life of a modern compressor cannot be compared with the life of older models. If we compare compressors produced after 2000, inverter compressors will last 40-60% longer than conventional ones.

No. 5 – Temperature

Temperature differences in a regular refrigerator can be 1-2 degrees between on and off cycles. Thanks to the use of an inverter compressor, fluctuations do not exceed 0.5 degrees.

The difference is small; for storing most products it does not matter. But if there are medicines or perishable fruits in the refrigerator, this is important. The use of inverter technology allows them to be stored in optimal conditions.

Minuses

#1 – High cost

An inverter compressor has a more complex design and is more expensive than a conventional linear compressor of similar power. To ensure its operation, “smart” electronics are needed, which also increases the cost of the refrigerator.

Previously, the price difference between conventional and inverter refrigerators was very large. It gradually decreases, and the efficiency of technology increases. Now, with the same power and chamber volume, inverter models are not much more expensive than conventional ones.

#2 – Current Sensitivity

Inverter compressors are sensitive to voltage fluctuations. If the refrigerator has just been plugged in, or a lot of unrefrigerated food has been placed in it, problems may arise.

In such cases, the compressor starts working at full power to quickly cool the chamber. And if there is a voltage drop, its operating speed will increase above the maximum. This will lead to premature wear, the winding may burn out, etc.

Many modern mid- and premium-class models provide surge protection. If it is not there, you can install a surge protection circuit breaker or a stabilizer.

No. 3 – Repair and diagnostics

The electronics of the control board and the design of the compressor for inverter refrigerators are more complex than for conventional ones. In the event of a breakdown, it is more difficult to find the fault. To eliminate it, specific parts and spare parts may be required.

The time and cost of repairs are 20-30% more. If the compressor completely fails, this is a big problem. The price of an inverter model is 30% or more higher than start-stop. Therefore, it is important to follow the operating instructions for the refrigerator.

#4 – Selection and Availability

When there is a need to replace a compressor, the original is not always available. Sometimes it is necessary to install a more powerful or reliable one, but the choice is limited. With a small assortment, sellers greatly inflate the price.

This is especially true for linear inverter compressors. They are not widely distributed; they are mainly found in LG and Kenmore refrigerators. Therefore, the easiest way to find a replacement is in service centers. But the prices in such organizations are steep.

No. 5 – Search for a master

When repairing a refrigerator with an inverter compressor, especially a linear type, you need a highly qualified technician. Such models are rare; many lack experience. And here there are two options - either pay good money to a specialist, or hope that an inexperienced refrigeration technician will be able to figure it out.

What other compressors are there in LG refrigerators?

Regular compressor. It is an electric motor that rotates a conventional piston pump, which in turn pumps the refrigerator’s refrigerant. These are found in the most ancient refrigerators and are turned on either at 100% power or at 0%. This leads to temperature changes inside the refrigerator chambers.
Linear. It differs from the usual one in that it does not have an electric motor. Instead, there is an electromagnetic coil, in the core of which a pump piston is installed. Such a compressor has no rotating parts, as a result of which it consumes less electricity, makes less noise (at the level of an inverter) and costs less. It also works either at 100% power or turns off completely. This type of compressor is the most common. You can tell when the engine starts by clicking. But there are significant drawbacks here. Firstly, constantly running at full power can cause serious damage to the compressor. Secondly, when the engine starts, the load on the network increases significantly, which entails high energy costs. These and many other shortcomings served as the reason for the introduction of inverter compressors into production.
Linear inverter. It does not have an electric motor and can change the speed of the pump piston. This type of compressor is the quietest and most economical to date.
Scroll compressor. Compression of the refrigerant in a scroll refrigeration compressor occurs due to the movement of one spiral inside the other. Such compressors are characterized by high reliability, low noise and vibration levels. The problem with scroll compressors is that they are difficult to repair. The spirals are located in a sealed chamber, access to them is difficult. Such compressors are used in high-power refrigerators and freezers, and automobile air conditioners.
Rotary (screw) compressor. The working elements of a refrigerator screw compressor are two adjacent screws. At the inlet, refrigerant is supplied to them in a gaseous state. As the screws rotate, they pump out freon, compressing it. As the pressure increases, the temperature of the gas increases. Rotary compressors are more efficient than piston compressors and are less noisy. But they have the shortest service life. Nowadays they are rarely seen. Only a few manufacturers install them on new models.
Piston (reciprocating). The cheapest and most common type of compressor. Gas compression occurs due to the work of the piston and the alternate opening and closing of valves. The piston is driven by the engine through a crank transmission. Piston compressors are characterized by high levels of vibration and noise. Their service life is longer than that of screw compressors, but lower than other types of compressors. Manufacturers install them to reduce the cost of equipment.
Inverter piston compressor. For some reason, 99% of sites forget about this type of compressor. Although they are found in 80-90% of inverter refrigerators. Inverter piston compressors are slightly more expensive than conventional piston compressors, but much cheaper than linear ones. In terms of their design, this type of compressor is practically no different from piston compressors. The difference is that the speed of rotation of the shaft in it is regulated by the electronic control board of the refrigerator. Accordingly, the piston speed changes.

How to choose an LG refrigerator

There are many refrigerator options with different features and benefits that you can consider. To get an idea of the types of LG refrigerators available in the market, consider the following points.

Single-door refrigerator: more compact and more economical

Each type of refrigerator has its own advantages. However, the main function is the same, namely to maintain the freshness of food and drinks.

Single door refrigerators usually have a limited number of compartments, but they are enough to store essentials. For example, cooking ingredients, bottled drinks, fruits. This type of refrigerator is also very suitable for one or two people

Double door refrigerator: with separate freezer

A double door refrigerator is a type of refrigerator that carries the concept of separate storage space between the freezer and a regular refrigerator. The storage space that a two-door refrigerator offers is usually greater than that of a single-door refrigerator.

Door-in-Door™ Multi-Door Refrigerator: More dedicated storage space

Door-in-Door refrigerators with more than two doors hold up to 600 liters. Each door of this refrigerator, be it the main door or the secondary door, has a compartment with a different storage function. You can also organize or store food and drinks more neatly.

The optional door compartment allows you to store snacks such as cheese, bottled drinks and more. In terms of its size, this refrigerator has 9% more storage space and additional shelves.

Side-by-side refrigerator: freezer on the right and refrigerator on the left

This type of refrigerator is different from a double door refrigerator, which has top and bottom storage space. The side-by-side refrigerator has storage space on the right and left sides. The more modern design certainly makes this refrigerator more stylish.

In addition to a more modern design, this type of refrigerator also has a larger capacity. Each compartment has different functions so you can store more food and drinks. For those who have a large family, choosing this refrigerator is a good choice. However, due to its large shape and size, you will automatically need more space.

LG offers a wide selection of Side by Side refrigerators. You can choose the color model that will look best in your kitchen

Multi-door refrigerator: more storage space

Multidoor refrigerator is a more modern refrigerator model and has a larger capacity. Another feature that gives the design a futuristic look is the LED display on the door. The LED function will make it easier for you to adjust the temperature of your refrigerator and freezer without opening the refrigerator door.

InstaView Door-in-Door™ Refrigerator: Features a sophisticated clear panel

Did you know that how often you open your refrigerator door will affect your electricity consumption? When the refrigerator door is opened, the warm air from outside will mix with the air inside the refrigerator. This condition causes unstable temperature in the refrigerator and leads to increased energy consumption.

However, thanks to the technology and design of the InstaView Door-in-Door™ refrigerator, you can save even more energy. This type offers a smart solution that allows you to see what's inside the refrigerator without opening the door. This refrigerator has a glass panel that lights up when pressed twice.

Pay attention to the features offered

LG refrigerators are equipped with the latest technology and are designed to simplify work and pamper its users. However, not all features are what you really need. To save more energy, choose a refrigerator with an energy-saving feature.

LG has developed greener technologies in almost all of its products. These technologies make it possible to produce energy-efficient refrigerators. Currently, LG refrigerators are equipped with an inverter linear compressor and low voltage stabilization (LVS) technology.

For more information about choosing a refrigerator, read: How to choose a refrigerator and which one is better to buy?

Both of these technologies can save up to 32% in daily energy consumption compared to other refrigerators. Despite automatic saving, the freshness of food and drinks in the refrigerator is maintained. Interestingly, LG provides a warranty of up to 10 years on its inverter linear compressor.

Do you want your food and drinks to stay fresh for a long time? Check out the Fresh Balancer™ feature

The longevity of food and beverages is largely determined by how they are stored. One of the features offered by the manufacturer LG is Fresh Balancer™. This function maintains humidity levels to keep food fresh longer.

Do you want to remotely control and monitor the operation of your refrigerator? Rely on Smart ThinQ

Nowadays, consumer electronic equipment has adapted to evolving technologies. One of the smart features that some LG refrigerators offer is Smart ThinQ™. This function is, of course, very useful to set up and even control the operation of the refrigerator remotely.

Another benefit of this feature is the early damage detection service. If the refrigerator is damaged or malfunctioning, you do not need to worry and immediately rush to a professional service. Your smartphone, which has LG Smart ThinQ™ installed, will analyze the problem in the refrigerator.

Comparison of an inverter compressor in an LG refrigerator with a linear one

The more complex the design, the more unexpected the cause of failure may be. Therefore, you need to know how to check this or that node. The inverter compressor in the refrigerator is tested with a device from DAIKIN, an inverter analyzer. The task is to find what is faulty, the electronic unit (board) or the electromechanical part. Failures in the network can lead to a malfunction if protection in the form of a voltage stabilizer is not installed.

A linear compressor is much simpler than an inverter compressor. He is not afraid of voltage surges. But the irregular operation mode is accompanied by peaks in energy consumption during the startup period. In the same way, the temperature inside the chamber changes within the range of the thermostat. Such cyclicality does not benefit the products; equipment is destroyed. This means that the inverter compressor in the refrigerator is more technologically advanced in all respects, which is confirmed by measurements.

Many people ask what an inverter is and how it differs from a linear compressor in terms of the efficiency of the refrigerator. Is it worth overpaying? Budget models are equipped with standard components. In domestic use, a well-regulated refrigerator makes little noise. But frequent starts and stops not only consume 40% more energy, but also destroy the metal.

A common cause of system failure is the thermostat. This device has several components that require monitoring. The spring for closing the relay contacts has weakened, the seal of the freon tube has broken - the refrigerator is leaking. Vibrations may cause a microcrack in the circuit and freon leakage.

Repairing a linear compressor with refilling is not cheap. Therefore, if funds allow, it is better to buy a model with an inverter heart. But the device has one significant drawback. When connecting inverter compressors for refrigerators, a stabilizer must be installed in the line or a built-in Volt Control must be provided, a technology that does not allow the engine to turn on until the voltage is restored. Failure of an inverter due to changes in parameters in the network is a non-warranty case.
