What is the difference between an inverter air conditioner and a non-inverter air conditioner? Main characteristics, advantages and disadvantages

For today the consumer is offered a wide choice of air coolers. In the selection process, people pay attention to the technical characteristics of such equipment. However, the first thing you need to know about the principle of its work.

There are inverter and non-inverter (usual) varieties. The user must understand how these devices behave during operation. Therefore, before buying, you need to find out what is the difference between an inverter air conditioner and a non- inverter air conditioner .

How does a normal air conditioner work?

Going into the store of home appliances, the buyer is faced with the fact that there are different principles of operation of such devices. And the question is reasonable: how does the inverter air conditioner differ from the simple one? For a detailed answer, one must understand the principle of operation of both varieties.

The compressor is the heart of the air conditioner. He 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 reading with a user-defined level.

If there are differences, the compressor turns on and starts to work at full power. Once the desired room temperature is reached, the device shuts off the engine. The fan continues to operate. The sensor monitors the temperature all the time. As soon as it rises a few degrees, the compressor turns on again. He will, as before, work at full capacity.

Principle of operation of inverter air conditioner

When studying the question of how an inverter air conditioner differs from a non-inverter air conditioner, one should also consider the principle of operation of the first variety. Initially, it also includes a compressor at full capacity and cools the air in the room to a predetermined level.

After this, in contrast to the classic equipment, the inverter compressor is not completely switched off. It supports work at low power. This allows the technician to compensate for incoming heat flows in the room.

The temperature difference between the user specified and the actual value is only 1 degree. Disconnection of this air conditioner also occurs.

Disadvantages of the conventional system

It is important for any user to know the difference in the operation of the equipment. It is interesting how the inverter air conditioner differs from the non-inverter air conditioner. Feedback from experts and ordinary users can identify a few shortcomings of classic models.

One of the most significant moments is a large load on both the system of the air conditioner itself and electrical communications. After all, every time the compressor turns on and runs at full power. The life of the equipment, according to the manufacturers of such equipment, is decreasing.

The second significant drawback is a rather strong flow of cold air. It's like a draft. With prolonged exposure to a stream of cold air, you can get a cold or various inflammations.

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

Characteristics of operation of the inverter

Features of operation allow to understand, than the usual conditioner from an inverter differs. The characteristics of the latter's work distinguish the equipment from the classical version.

Inverter technology can operate 24 hours a day. At the same time, according to the producers' comments, power consumption 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 operate. There is also no significant load on the mains.

But inverter air coolers have several drawbacks. Their cost is much higher than that of conventional air conditioners (by 30-40%). Also, such a system is more susceptible to the negative influence of voltage drops. Therefore, buying an inverter, you should immediately buy a stabilizer.

What to choose?

After all of the above, the question may arise, why are the classical versions of devices still on sale? In addition to the cost, this technique has its advantages. Therefore, it is necessary to take a responsible approach to the purchase process, considering an inverter or a conventional air conditioner. What to choose, expert advice will help.

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

Fine adjustment is only available 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 classical version of the equipment in the archive.

Comfort inverter operation will also not be felt in a room with uneven heat input. For example, in an office, a public building, people often come, doors and windows open. The air conditioner is not able to react quickly to such changes.

Manufacturers of machinery

Having dealt with the main points, than the inverter air conditioner differs from the usual, it is necessary to say a few words about the manufacturers. If the decision was made in favor of buying 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.

Leaders in this area are Mitsubischi Electrik and Daikin. The first brand produces more expensive products, but such equipment operates without noise. Daikin air conditioners are slightly cheaper, but they still publish insignificant sounds. If you want to buy an air cooler for your home, these two manufacturers will be the most comfortable to use.

If you buy top-end models is expensive for the family budget, you can consider buying equipment from a Japanese company Sahyo. The Mini Shiki Sai series fully satisfies the requirements put forward by the user to inverter air conditioners.

Repair of equipment

When choosing a cooler, one should consider the maintainability of inverter air conditioners. The difference from classic varieties is a considerable cost of maintenance.

The compressor and the cooler system are the same in both types of equipment. In the event of a breakdown, it is in this area that repairs will be worth equivalent. Although, according to experts, this part of the air conditioner breaks quite rarely.

But electronics is very different in classical and inverter equipment. In the second group of devices, power modules are used. They are very prone to voltage drops in the network. If a breakdown occurred in the area of the board, the repair would be expensive (comparable to the cost of a new classic air conditioner).

In addition, there are difficulties with the acquisition of the necessary power modules. Often they are simply not available.

Efficiency of operation

Studying the difference between an inverter air conditioner and a non-inverter air conditioner, one should say about the economy of their operation. In conditions of increasing the cost of electricity this is an important factor that influences the choice.

Manufacturers of inverter varieties claim that their devices are more economical than conventional ones by 30-40%. However, there are no officially confirmed tests on this issue. It is also necessary to take into account the operating conditions in which the machinery operates.

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

Life time

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

But experts say that the compressor is a fairly strong, durable system, even if it works in full force. But the electronic part of inverter varieties breaks down, unfortunately, often.

Therefore, when studying how the inverter air conditioner differs from non-inverter air conditioner, durability can not be attributed to the use of advanced equipment. Only a thoughtful choice will guarantee a successful acquisition.
