What is an inverter air conditioner - the principle of operation, advantages and advice of choice

Given the changes that the climate on the planet is undergoing, the increasing demand for household appliances for indoor air cooling is quite natural. The assortment of such models is huge, the criteria for their choice are different, but the practice shows that basically buyers are guided by the cost of the air conditioner, as someone does not want to penetrate into the various technical nuances of its functioning in principle, but to some they are simply not understandable.

Those who want to not only increase the level of comfort in their home, but also significantly save on electricity and maintenance of the device, this article, we are sure, will interest.

It is known that it is best to evaluate this or that product in comparison with analogues. This is how you can identify both the advantages and certain "minuses" of a particular model. In order to make the features of inverter-type air conditioners more clear, it is necessary to dwell on the general principle of the operation of such products. Without "loading" the reader with a specific terminology, we will only point out an algorithm that is understandable to all.

In simplified form, it can be represented in this form:

In principle, everything is simple. When the readings are equal, the sensor gives the command to stop the compressor, which is processed by the electronics. If the temperature difference exceeds a certain value( depending on the technical solution and, as a rule, is a couple of degrees), the compressor starts working again. And so - cycle after cycle( on / off).But with this method of cooling, there are a number of "minuses", which experts note.

Frequent turns of switching on and off negatively affect the reliability of any technical device, since they are accompanied by short, but increased loads. First of all, this refers to the starting current. With this mode of operation, experts recommend using air conditioners not more than 8 hours a day( total running time), since the compressor needs a "rest".

1. According to statistics, it is at the moments of start-up or shutdown that up to 90% of all malfunctions occur. Consequently, devices operating in this mode are in a "risk zone"( in terms of rapid breakdown).
2. In conventional air conditioners for air cooling, the compressor operates at the maximum possible power, since its task is to eliminate the difference between the actual and expected temperature as soon as possible. This leads to its increased wear and reduce the period of maintenance-free operation.
3. "Constructive" tuning of the split system for quick cooling leads to the fact that when switching on, passing to the limit mode of operation, it creates drafts. Someone does not pay attention to this aspect, but this is not very similar to the generally accepted understanding of the comfort of use.
4. The level of noise, although small, but there are many people to whom such devices simply interfere.

Getting started is the same:

But here the principle is completely different. If the compressor is turned off in a conventional device before the new switch-on, in the inverter models it continues to work, but already in a "soft" mode, maintaining the temperature in the room with a sensor that actually controls its operation.

Features of inverter air conditioners

1. Reduces power consumption, reduces the load on the compressor, since it operates at a partial power. Its value can vary between 5 and 90%.If the doors to the premises( for example, administrative buildings) are constantly opening / closing, then it is slightly larger. With regard to the operation of air conditioners in homes, the compressor operates at almost the minimum load.
2. We indicated that regular models require periodic "rest".Inverter-type products are designed for continuous operation, that is, they can be "chased" at least 24 hours a day, without switching off. At the same time, energy consumption will be insignificant. For people who do not tolerate heat, these conditioners are especially attractive.
3. The noise level is minimal, since the air conditioner does not need to eliminate the temperature difference, since it is maintained at a certain level. For a bedroom or a nursery - that's right.
4. As a consequence, there is a reduction in the probability of breakage due to constant load changes, periodic on / off and increased reliability of the device.

In summary, we can say that the inverter air conditioner is not just a device for air cooling, but a real climate control system.

Disadvantages of

• Energy quality requirements. Considering the condition of our power grids, it is also necessary to purchase a voltage regulator.
• For convenience, you have to pay. Naturally, prices for inverter models are much higher than for conventional air conditioners. On average, in 1,3 - 1,4 times. But this disadvantage is relative, since the cost of such "inverters"( the simplest ones) starts from 16,500 rubles. At the present time - not so much.

Conclusion

• For those who like to create maximum comfort for themselves, to date, inverter models - the best option.
• If the task is only to periodically lower the temperature in the rooms, it is enough and cheaper, conventional appliances.

It should be noted that the class of "inverters" is quite numerous. Such products differ in different parameters, for example, temperature range, noise level. Therefore, before acquiring such a device, you should familiarize yourself with the criteria for its evaluation of the appropriateness of using in specific conditions.
