Today, the consumer is 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 know about the principle of its work.
There are inverter and non-inverter (ordinary) varieties. The user must understand how these devices behave during operation. Therefore, before buying, you need to find out how the inverter air conditioner differs from the non- inverter one .
The principle of operation of a conventional air conditioner
Having come to a home appliance store, the buyer is faced with the fact that there are different principles for the operation of such devices. And a reasonable question pops up: what is the difference between an inverter air conditioner and a simple one? To get a detailed answer, you should understand the principle of operation of both varieties.
A compressor is the heart of an air conditioner. They will disperse the refrigerant through the system. Classic air conditioning 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 switches on and starts to run at full capacity. As soon as the desired room temperature is reached, the device turns off the engine. The fan continues to run. The sensor constantly monitors the temperature. As soon as it rises by several degrees, the compressor switches on again. He will, as before, work at full capacity.
The principle of operation of the inverter air conditioner
Studying the question of how the inverter air conditioner differs from the non-inverter one, one should also consider the principle of operation of the first variety. Initially, it also turns on the compressor at full power and cools the air in the room to a predetermined level.
After that, in contrast to the classical equipment, the inverter compressor does not turn off completely. It supports low power operation. This allows the technique to compensate for incoming heat fluxes in the room.
The temperature difference between the user-specified and the actual value is only 1 degree. Turning off such an air conditioner also occurs.
The disadvantages of a conventional system
For any user, it is important to know the difference in the operation of the equipment. It is interesting how the inverter air conditioner differs from the non-inverter one. Feedback from experts and ordinary users allows us to highlight several shortcomings of classical models.
One of the most significant points is the heavy load on both the air conditioner system and the electrical communications. After all, every time the compressor turns on and works at full capacity. The life of the equipment, according to manufacturers of such equipment, is reduced.
The second significant drawback is the rather strong flow of cold air. It looks like a draft. With prolonged exposure to a stream of cold air, you can get a cold or various inflammations.
The disadvantages of conventional air conditioners should also include a high level of noise and the ability to operate only 30% of the time per day.
Inverter operation characteristic
Operational features allow you to understand the difference between a conventional air conditioner and an inverter. The performance characteristics of the latter distinguish the equipment from the classic version.
Inverter technology can operate 24 hours a day. At the same time, energy consumption, according to the comments of 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 in operation. There is also no significant load on the power grid.
But inverter air coolers have several drawbacks. Their cost is significantly higher than that of conventional air conditioners (30-40%). Also, such a system is more susceptible to the negative effects of voltage drops. 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 the classic types of devices still on sale? In addition to cost, this technique has its advantages. Therefore, you should be responsible for the purchase process, considering an inverter or a conventional air conditioner. What to choose, expert advice will help.
Firstly, it should be noted that the classic versions of air conditioners are more effective in cooling large technical rooms. Secondly, inverters are also different. If the adjustment range of their power is small, then the person will not get the expected effect. It’s 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 the equipment in the archive.
The comfort of the inverter will also not be felt in a room with an uneven flow of heat. For example, people often come in the office, public premises, 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 the inverter air conditioner differs from the usual one, a few words should be said about the manufacturers. If the decision was made in favor of buying an expensive improved variety, 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 works without noise. Daikin air conditioners are a bit cheaper, but they still make minor sounds. If you need to purchase an air cooler for the home, then these two manufacturers will be the most comfortable to use.
If you buy top models costly for the family budget, you can consider buying equipment from the Japanese company Sahyo. The Mini Shiki Sai series fully satisfies the requirements put forward by the user 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 technology. In the event of a breakdown, it will be in this area that the repair 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 the classic and inverter equipment. In the second group of devices, power modules are used. They are very susceptible to power surges. If a breakdown occurs in the area of the board, the repair 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.
Economic operation
Studying how the inverter air conditioner differs from the non-inverter one, it should be said about the efficiency of their operation. Given the increasing 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 trials on this issue. The operating conditions in which the equipment operates should also be considered.
If we 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 do not agree 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 does not undergo frequent abrupt starts. Its power is usually quite low at work.
But experts argue that the compressor is a fairly strong, durable system, even if fully operational. But the electronic part of the invertor varieties fails, unfortunately, often.
Therefore, when studying the difference between an inverter air conditioner and a non-inverter air conditioner, durability cannot be attributed to the benefit of advanced equipment. Only a smart choice will guarantee a successful purchase.
