What does inverter split system mean? Comparison of an inverter air conditioner with a conventional one

In the process of improving technology, a conventional air conditioner has evolved and been improved to an inverter-type split system. Both categories of devices have not only some similar features in operation, but also significant differences and their own characteristics, which can significantly affect the choice of buyers.

In order not to make a mistake when purchasing, it is worth understanding the operating principles of each, considering how the advantages and disadvantages of an inverter air conditioner differ from the properties of an ordinary device, and choosing the best option based on the qualities.

The working process of a conventional air conditioning system

A simple air conditioner is represented by a wide range of affordable models. Its internal processes include the ability to circulate heat through its absorption in the form of steam and release through condensation. Conventional air conditioners deal exclusively with circulating air from the outdoor space to the indoor space and back. This type of system cannot independently create a decrease or increase in temperature.

A regular air conditioner is divided into 2 blocks:

Inner part. Functions as an evaporator.
Outer box Performs the functions of a capacitor.

The principle of operation is to cool the air to the temperature set by the user. After heating, the compressor stops and goes into sleep mode, at which time the fan continues to function, monitoring the temperature in the room using a sensor. If the space is heated by a certain number of degrees provided by the system, the compressor is activated again.

Internal structure and operation of a conventional air conditioner

Advantages and disadvantages of a conventional air conditioner

The usual one has been successfully performing its functions for decades. Among its main advantages are:

wide range of models;
reasonable prices and a large selection of high-quality budget options;
accessible, understandable method of operation;
possibility of self-care and repair;
minimum cost of services when calling a specialist.

But, in addition to a number of advantages, conventional devices have disadvantages:

significant energy consumption;
short lifespan of the device;
create a high noise level during operation.

Scheme of operation of inverter technology

Inventory systems are similar in principle to simple devices. The main thing is the presence of an inverter, which coordinates the power of the compressor and changes its performance. Immediately after turning on, the device adjusts the temperature to the set point and maintains it with the intensity of engine rotation.

Principle of inverter design

Pros and cons of an inverter

Inverter systems have many more advantages than conventional air conditioners. These include:

rapid achievement of the temperature set by the user;
exact execution of the established regime;
low noise level during slow rotation;
uniform use of electricity, no surges;
low energy costs;
temperature control within a specified area, even outside the same room, without going beyond boundaries.

Despite the large number of advantages, inverters also have several disadvantages. Most often, buyers note:

high prices;
sensitivity to voltage changes;
expensive repairs;
Difficulties in selecting parts for repairs.

Differences in work

All differences between an inverter air conditioner and a conventional one are based on the advantages and disadvantages of each type of device. The differences are as follows:

Cost level. Although recently, competition among manufacturers has prompted them to reduce prices.
Sensitivity to voltage changes. Conventional air conditioners are more resistant to power outages.
Precise temperature maintenance. Inverter air conditioners more accurately determine the ambient temperature and maintain the necessary balance.
Noise level. Inverter technology is the quietest, especially if the country of origin is Japan.
Degree of electricity consumption. Simple air conditioners significantly exceed inverters in terms of energy consumption.
Cooling rate. Inverter appliances cool and heat the room faster.
Lifetime. Conventional split systems wear out faster.

Comparison of the operating principle of two types of equipment

Which option to choose

Before purchasing, many buyers are faced with the problem of which air conditioner to choose. When deciding this issue, you will have to take into account the pros and cons of both options, drawing the appropriate conclusions in whose favor the difference leans .

According to many of the parameters indicated in the comparison of the distinctive features of operation, the inverter shows better results than a simple air conditioner. The high cost justifies the costs, which exceed the price of a conventional device by 40%, by durability and savings on electricity bills.

Modern inverter systems are best chosen for residential and office premises where people have to spend a sufficient amount of time. The noise level will allow you to concentrate on your work and not notice the equipment. For large walk-through or industrial premises, you can opt for simple options so as not to overpay.

Inverter of course!

And not because it is 15-20% more expensive and this is beneficial to the company. The markup is minimal on both inverter and classic “on/off” models.

Here are three factors:

more reliable and more durable
more economical and quieter in operation
Maintains temperature more accurately, providing climate control function

Inverter or conventional air conditioner... what to choose?

So which air conditioner should you choose: inverter controlled or classic? We would advise installing an inverter split system. Just 8-7 years ago they cost almost twice as much as their analogues. But now the difference in cost is 15-20%: when comparing the on/off model with a basic inverter from the same manufacturer.

Approximately 95% of installed equipment is inverter. Classic air conditioning systems are installed in the vast majority of cases either in server rooms (additionally equipped with a winter kit for operation down to -40 in cold weather) or in budget institutions where “cheap and cheerful” is required. Better technology is being chosen for apartments and country houses.

About the company "Project Climate"

A huge advantage in the operation of an inverter split system is that in order to quickly achieve the temperature set from the control panel, the “brains” of the inverter increase the speed, and therefore the power, of the rotation of the compressor engine. The air conditioner operates in enhanced mode until the temperature in the room where the split system is located becomes equal to the temperature you set from the control panel. When the set parameter is reached, the rotation speed of the electric motor drive decreases, but unlike the non-inverter model, the compressor continues to operate. The result is a smoother maintenance of a constant temperature. It is also worth noting the minimal deviations in maintaining the set temperature.

Find out more about the principle of inverter technology:

The inverter does not need to restart the engine, just like a non-inverter engine: the compressor is always on. During operation of the inverter air conditioner, there is no constant switching on/off of the compressor of the external unit. This allows you to reduce energy consumption, reduce noise levels, more accurately maintain the set temperature (temperature fluctuations do not exceed 1.0 °C), and operate in a wider range of external temperatures. Many people confuse turning on and off the compressor located in the external unit with turning on and off the fan located in the internal block of the split system. So: you will practically not feel the difference in the operation of the inverter and conventional equipment, because the fan of the indoor unit rotates constantly, the heat exchanger tubes are cold for quite a long time and when the compressor is turned off, the air conditioner always blows cold air into the room, while rotating (if programmed and the functionality allows) the shutters, evenly distributing the air throughout the room. In general, they work almost the same. For a non-inverter air conditioner, the temperature of the outlet air only fluctuates slightly (this is precisely the result of connecting the compressor).
A positive point is the fact that due to the absence of amplitude cyclic switching on/off of the compressor, the service life of the equipment is extended. The physics is simple: starting up a compressor (as well as cold starting an engine) is accompanied by increased wear of rubbing parts due to the fact that the oil in the freon mixture flows into the crankcase in the compressor and for the first seconds it operates without lubrication (metal on metal).

As a result, we can say that both power control technologies have a right to life, both create comfort in your home. But let's summarize the result.

The strengths of inverter systems include the following:

quick access to the specified temperature regime. The speed is explained by the possibility of increasing the frequency of the current and, accordingly, the power of the electric drive of the compressor;
smooth maintenance of the set temperature due to the absence of cyclic switching on and off;
operation of fan motors at low speeds reduces the noise level of both the indoor unit (from 20 to 26 dB) and the outdoor unit;
savings in energy consumption (up to 60% compared to previous series of non-inverter units!)

Weak sides:

relative high cost of models compared to conventional blocks. The cost of such equipment is 10-25% higher than its standard counterparts;
Previously, increased sensitivity to voltage changes was noted. But at the moment, most leading manufacturers of inverter equipment have built-in protection against voltage surges

What is an inverter type air conditioner? In appearance, such climate control devices are no different from their own kind. The external assembly is also typical for representatives of such devices. The same can be said about functions. But at the same time, an inverter-type air conditioner is considered a more advanced device with stable operation. Analyzing the capabilities of inverter technology will help you understand whether this is true or a publicity stunt.

What are the differences between conventional air conditioners and our heroes? And what is an inverter split system? Which air conditioner is better - inverter or conventional? Is there a risk of overpaying? These and other questions arise in the mind of the future owner of climate control equipment. And you can answer them only by analyzing the differences between an inverter air conditioner and its conventional counterpart.

Regular air conditioner

A conventional appliance must regulate the temperature in the room based on on the temperature sensor readings- the latter is set by the user. The bottom line is that if the specified indicator is exceeded, the device simply turns off. Naturally, after some time the temperature begins to rise, so a restart occurs, during which a conventional air conditioner begins to operate at full power. Thus, the equipment works for the entire specified time.

Such on-off switches do not have the best consequences:

surge in the power grid (increased energy consumption);

wear of mechanism parts.

It turns out that a non-inverter device works cyclically. And in order for its engine to accelerate, large starting currents are consumed. After the start has occurred, the compressor begins pumping 50% of the total volume of freon from the low pressure zone to the high one. In this case, all systems are used to the maximum.

How does the pressure normalize after the compressor is turned off? The throttle system is responsible for this. But in any part of the system remains risk of freon boiling(can occur in the main line, in the receiver, and in the capillary tube). And the unused potential cold comes out, irrationally cooling the air outside. Of course, there is compensation, but it is small - at the same time, cold is generated into the room. To some extent, this equalizes the losses when the compressor is turned on again.

Inverter model

With an inverter air conditioner, everything is different than with conventional models. Here the control unit converts alternating current into direct current, and then converts it back into alternating current, but at the current frequency.

Knowledge of physics will help answer the question of what an inverter is in an air conditioner. It turns out that the inverter is aimed at increasing and decreasing the usual network frequency. This inverter control of the power of the air conditioner formed the basis for the name of the device. It influenced change in engine speed compressor, and, therefore, on its performance.

The operating principle of an inverter air conditioner consists of the following technical actions. The device has a thermostat, designed as a standard temperature meter, but when the desired level is reached, it does not turn off, but simply reduces the power in operation (leaving only 5-10% of the usual). In this case, the temperature will drop much more slowly, but when the permissible threshold is passed, the compressor will start again. An inverter compressor operates in the range of 1-1.5 degrees (compared to conventional ones, for which such data varies from 1 to 5°C). In this case, there will be no 100% load on the device.

The inverter air conditioner circuit includes the usual outdoor and indoor units.

The outer one contains elements such as a compressor, followed by a system filter with freon, followed by a fan for cooling freon and a condenser. Also worth mentioning is the control and connection board.
Now about the indoor unit: the first thing worth mentioning is the evaporator for cooling the air, the fan, the parts of the blinds, as well as the filter and pan into which the condensate drains.

Pros and cons of using inverter systems

Having figured out what the model name “inverter split system” means, it’s time to talk about the pros and cons of the units. First, about the bonuses - even after a short period of use, users manage to appreciate the benefits of such technology.

The difference between an inverter air conditioner and a conventional one is that it has no operating restrictions (for a traditional device this is no more than 8 hours per day).
You don't have to worry about network congestion. And their absence is already energy saving in the range from 30 to 50%. When paying utility bills, the difference is significant.
The device can be called economical - there are no “idle loads”.
The set temperature is precisely maintained.
The effect of the air flow also becomes more comfortable: during conditioning, a soft flow of 12-15 °C will be released. This reduces the likelihood of getting sick (as happens when using a regular analogue).
Reduced noise level(only 19-23 dB) allows you to operate such a device even at night (in comparison, for the conventional version it is 30-32 dB).
Long service.
Finally, a device with an inverter will help to heat the room even at temperatures reaching -25 degrees.

Inverter air conditioners also have certain disadvantages.

The “highlight” in the form of soft thermoregulation is not suitable for every room. What is ideal for bedrooms and children's rooms is absolutely ineffective at creating a comfortable atmosphere in offices and other public places (people constantly enter and exit, close and open windows).
You should not install an inverter air conditioner in the kitchen; its operation will be disrupted by the heat from the kettle or stove. Climate control technology simply cannot cope with such constant temperature changes.
The maintainability of the devices does not have the last word. For example, the types of inverter and non-inverter compressors are absolutely the same, but if the electronic board fails, replacing it will cost at least 10,000 rubles. And spare parts cannot be found widely.
For economic reasons, it is not profitable to operate such a unit in a dacha that is rarely visited by residents.
Finally, high price device makes it difficult for anyone to purchase it.

Choosing the best model

Today, the split system of the presented inverter type is a product developed by almost all manufacturers specializing in the production of climate control equipment. Among them are such names as Daikin, Toshiba, Panasonic, Mitsubishi and many others. Each brand's products have their own pros and cons.

Daikin are the most popular climate control devices, according to user reviews. They operate on safe freon, and are ready to fulfill their mission even in harsh winter conditions. There are two lines of devices on the market - FTX and FTXN. Both have excellent economic and ergonomic performance, a long service life, and have floor-mounted and wall-mounted inverter air conditioners. Another bonus is the declared low noise level (in top models it can even be 19 dB, but most buyers still object that noise still appears at higher speeds).

We found folk love and models from stampsLg. What attracts here is low wear and the ability to select a wide variety of temperature conditions without load on the electrical network. The unit can operate at very low speeds. The characteristics of this brand are marked by a fairly high level of power. But there are also disadvantages: the equipment is very sensitive and may not withstand large voltage surges.

Both the equipment itself and its components are very expensive.

Panasonic produces high-quality and affordable devices. The products of this brand are distinguished by the use of a pulse-type unit - this means that they are less susceptible to voltage surges. Many of the models are great for office spaces. They are also good for the home, as they have a night heating mode.

Now about BEKO- a brand that shows what inverter split systems are in all their beauty: ease of control is combined with high power (a more advanced unit is used). The model has a dehumidification mode and even has a built-in air ionizer.

About any inverter split from Electrolux They talk about it as a universal and high-quality good device. He earns positive marks, first of all, through good management. However, the model also uses special anti-icing protection.

Inverter from the brand Toshiba You can cool a room of 30 square meters. meters. There is a built-in pulse unit that protects the system from power surges. Energy efficiency will not exceed 80%. Split systems of this brand with inverter control are among the most affordable.

By the way, it was Toshiba that was the first to introduce such devices.

There is another brand worthy of mention - COOPER&HUNTER. Unlike other models, the units have a power converting unit. This inverter air conditioner also has the advantage of excellent speed control.

To choose the right split system with inverter control, you need to listen to the following recommendations.

If your budget is limited, it is better not to buy the cheapest inverter model available. It would be better if it were an ordinary split, but from a well-known manufacturer and with a good reputation.
It is better to choose a model with great power capabilities, especially if you plan to install it in a bedroom or children's room. Such a device will work without noise and draft.
Installation of the system should be entrusted only to professionals. According to service centers, 80% of all breakdowns are caused by improper installation.
It is best to carry out installation in the spring, and not during the “hot season”, when there are a lot of offers from incompetent specialists.

Preventative work

Even a state-of-the-art air conditioner can fail without proper care. It is important to know that split systems with inverter control require compliance with certain rules for their care.

Do not allow liquid to enter the cold circuit. This is fraught with the formation of acid, which will corrode the insulation of the engine.
It is important to constantly monitor the level of oil and refrigerant used. If freon decreases, the pressure in the system will also drop, and, therefore, the device will begin to wear out.
Regular cleaning the heat exchanger, because the accumulation of dirt is a direct path to its overheating, increased pressure and load.

Information about what inverter split equipment is allows you to understand in all its beauty the prospects for its use. But is it worth overpaying to buy it? The answer will be this: if you have a small budget, it is better to opt for conventional air conditioners, but of the highest class. It is important to have service centers where they can provide qualified assistance.

Air conditioners of this type can be recommended for installation in apartments - residents will appreciate the “soft” cold and quiet operation. But if there are constant power surges in the house, it is better to refuse such a purchase. And one more thing: you shouldn’t think that the device will quickly pay for itself due to its energy-saving consumption. According to experts, this period should be at least 5 years - during this time, no equipment is insured against breakdowns and overloads.

If you need to carry out welding work yourself, the question arises: what type of welding machine to purchase. Welding is the creation of permanent connections between welded parts at the atomic level. The welded connection is one of the strongest and therefore is used quite often.

During electric welding, heating and melting of the metal occurs due to the formation of an electric arc between the end part of the electrode and the surface to be welded. Sources of arc formation and maintenance are divided into several types:

Transformer.
Inverter.
Rectifiers.
Welding units based on internal combustion engines.

Let's consider two types that are most widely used: a welding machine based on a transformer and an inverter source of electric arc.

This is the simplest of welding machines that uses alternating current. It works using a transformer that regulates the mains voltage to the welding voltage. Transformer or induction welding machines are divided according to the following criteria:

Power (the greater the welding current, the thicker the metal it can be processed).
The number of posts, that is, jobs (how many people can work at the same time).
Voltage (single-phase or three-phase network).

Its advantage is a simpler and more reliable design, low cost, and high maintainability.

The disadvantages include the dependence of the arc on power surges, large weight and overall dimensions, and strong heating during work.

What is an inverter?

An inverter welding machine or simply an inverter is one of the energy sources for electric arc welding, which is based on use of high frequency current. Its operation is carried out by power electronics and a small transformer.

Its advantages are considered to be low energy consumption, compactness, low weight and size, and fairly high quality seams.

The negative aspects of the inverter include the relatively high cost, fear of moisture, dust and low temperatures (typical of budget models), sensitivity to voltage surges, and expensive repairs.

What do an inverter and a transformer welding machine have in common?

The similarity of these devices is their purpose - the formation and maintenance of an electric arc. But there are still some points that unite them:

The devices under consideration are united by the presence of a transformer, but of different sizes. Due to the preliminary receipt of high frequency current, inverters do not need to use large transformers. To obtain a current of 160 A, a transformer weighing 0.25 kg is needed. To obtain the same current in inductive devices, a transformer weighing 18-20 kg is required.
Possibility of smooth current adjustment. Transformer devices have this opportunity due to changing the size of the air gap in the magnetic circuit.
The devices are powered from a household (220V) or industrial (380V) network.
Most welding machines have short circuit protection.

What is the difference between an inverter and a transformer source of electric arc?

The dimensions and weight of a transformer-type welding machine are larger than that of an inverter. Industrial designs can weigh more than one hundred kilograms.
Operating principle. In the inverter, the alternating current of the network is converted by the primary rectifier into direct current, then again into high-frequency alternating current and then again changes to direct current at the secondary rectifier. In transformer-type welding machines, the current strength changes due to changes in the position of the magnetic core, that is, the core of the step-down transformer or the inclusion of a different number of turns of windings in the circuit.
The inverter has a more stable arc due to the stability of the welding current, which affects the quality of the seam.
The difference is in the design. The inverter is more complex and can be equipped with the following additional functions: HOT START– increasing the initial current to improve ignition of the welding arc. ARC FORCE- increasing the welding current to speed up the melting process and prevent sticking, that is, the arc is forced. ANTI-STICK– reduction of current when the electrode sticks to increase the time for its separation and protection from overload.
The process of learning to work on a transformer is more complex and time-consuming. However, having mastered these skills, you can easily work on an inverter.
The inverter produces direct current, the transformer operates on alternating current with a household power supply frequency of 50 Hz.
The power factor of the inverter is the highest of all welding equipment, and the efficiency exceeds transformer analogues by 20-30%.
Wide range of welding current changes.
The inverter has such an indicator as the intermittency coefficient (IC). It determines the time of continuous operation at maximum welding current. That is, if the CP is 50%, then after 10 minutes of operation it needs 5 minutes to cool down. Such requirements are not imposed on a transformer welding machine.
Possibility of using electrodes designed for both direct and alternating current.

Today there is a fairly wide selection of welding equipment on the market from various manufacturers. The choice of welding machine should be made based on the tasks that will be performed with its help.

Today, consumers are offered a wide selection of air coolers. In the selection process, people pay attention to the technical characteristics of such equipment. However, first of all, you need to learn about the principle of its operation.

There are inverter and non-inverter (regular) varieties. The user must understand how these devices behave during operation. Therefore, before purchasing, you need to find out how it differs from a non-inverter one.

The working principle of a conventional air conditioner

Entering a household appliance store, the buyer is faced with the fact that there are different operating principles for such devices. And the question reasonably arises: what is the difference between an inverter air conditioner and a simple one? To get a detailed answer, you should understand the operating principle of both types.

The compressor is the heart of the air conditioner. It will disperse the refrigerant through the system. A classic air conditioner is selected for a room with a certain size. The equipment sensor measures the ambient temperature and compares the readings with a user-specified level.

If there are differences, the compressor turns on and starts working at full power. As soon as the desired room temperature is reached, the device turns off the motor. The fan continues to run. The sensor monitors the temperature all the time. As soon as it rises by a few degrees, the compressor turns on again. It will continue to operate at full capacity as before.

Operating principle of an inverter air conditioner

When studying the question of how an inverter air conditioner differs from a non-inverter one, you should also consider the operating principle of the first type. Initially, it also turns on the compressor at full power and cools the air in the room to a predetermined level.

After this, unlike classic equipment, the inverter compressor does not turn off completely. It supports low power operation. This allows the technology to compensate for the incoming heat flows in the room.

The temperature difference between the user-specified value and the actual value is only 1 degree. This air conditioner also switches off.

Disadvantages of the conventional system

It is important for any user to know the difference in operating equipment. I wonder what is the difference between an inverter air conditioner and a non-inverter one. Feedback from experts and ordinary users allows us to highlight several disadvantages of classic models.

One of the most significant points is the heavy load on both the air conditioner system itself and electrical communications. After all, every time the compressor turns on and works at full capacity. The service life of equipment, according to manufacturers of such equipment, is decreasing.

The second significant drawback is the rather strong flow of cold air. It looks like a draft. If you stay under a stream of cold air for a long time, you can get a cold or various inflammations.

The disadvantages of conventional air conditioners also include the high noise level and the ability to operate only 30% of the time per day.

Inverter operation characteristics

Operating features allow you to understand the difference between a conventional air conditioner and an inverter. The operating characteristics of the latter distinguish the equipment favorably from the classic version.

Inverter technology can operate 24 hours a day. At the same time, energy consumption, according to comments from manufacturers, will be less than that of a conventional air conditioner. The noise level is minimal. There are no drafts. Therefore, this type of device is more comfortable to use. There is also no significant load on the power grid.

But inverter ones also have several disadvantages. Their cost is significantly higher than that of conventional air conditioners (30-40%). Also, such a system is more susceptible to the negative influence of voltage surges. Therefore, when purchasing an inverter, you should immediately buy a stabilizer.

What to choose?

After all of the above, the question may arise, why are classic types of devices still on sale? In addition to cost, this technique also has its advantages. Therefore, you should take the purchasing process responsibly when considering an inverter or a conventional air conditioner. What to choose, expert advice will help.

Firstly, it should be noted that classic versions of air conditioners are more effective when cooling large technical rooms. Secondly, inverters are also different. If the range of adjustment of their power is small, then a person will not get the expected effect. It is easier then to buy a cheaper conventional type of device.

Fine adjustment is present only in expensive models. They are purchased for small rooms, bedrooms or kitchens. Therefore, to maintain a low temperature in the warehouse, it is better to buy a cheap classic version of equipment from the archive.

The operating comfort of the inverter will also not be felt in a room with uneven heat supply. For example, in an office or public space, people often come in, doors and windows open. The air conditioner is not able to quickly respond to such changes.

Equipment manufacturers

Having understood the main points of how an inverter air conditioner differs from a conventional one, we should say a few words about the manufacturers. If the decision has been made in favor of purchasing an expensive, improved version, you should carefully study the technical characteristics of the model. If they are not high enough, it is better to purchase a cheap classic air conditioner.

The leaders in this area are Mitsubischi Electric and Daikin. The first brand produces more expensive products, but such equipment operates without noise. Daikin air conditioners are a little cheaper, but they still make minor sounds. If you need to purchase an air cooler for your home, then these two manufacturers will be the most comfortable to use.

If purchasing top models is expensive for the family budget, you can consider purchasing equipment from the Japanese company Sahyo. The Mini Shiki Sai series fully satisfies the user's requirements for inverter air conditioners.

Equipment repair

When choosing a cooler, you should consider the maintainability that inverter air conditioners have. The difference from the classic varieties is the significant cost of maintenance.

The compressor and cooler system are the same in both types of equipment. If there is a breakdown in this particular area, the repairs will cost the same. Although, according to expert reviews, this part of the air conditioner breaks down quite rarely.

But the electronics are very different in classic and inverter equipment. The second group of devices uses power modules. They are very susceptible to power surges. If the breakdown occurs in the circuit board area, repairs will be expensive (comparable to the cost of a new classic air conditioner).

In addition, there are difficulties in acquiring the necessary power modules. Often they are simply not on sale.

Economical operation

When studying how an inverter air conditioner differs from a non-inverter one, it should be said about the cost-effectiveness of their operation. Given the rising cost of electricity, this is an important factor influencing the choice.

Manufacturers of inverter varieties claim that their devices are 30-40% more economical than conventional ones. However, there are no officially confirmed tests on this issue. The operating conditions in which the equipment operates should also be taken into account.

If we take into account the cost of inverter air conditioners, their payback period is more than 5 years (comparable to conventional devices).

Life time

Another important aspect in studying air cooling technology is its service life. However, experienced experts disagree with this statement. Manufacturers explain such a long service life (8-15 years) of the inverter by the fact that the compressor of this system is not subject to frequent sudden starts. Its power is usually quite low when running.

But experts say that the compressor is a fairly strong, durable system even when operating at full capacity. But the electronic part of inverter varieties fails, unfortunately, often.

Therefore, when studying how an inverter air conditioner differs from a non-inverter air conditioner, durability cannot be attributed in favor of advanced equipment. Only a thoughtful choice will guarantee a successful purchase.
