The equipment of the listed brands, as a rule, is of high quality, the level of which is consistent with the declared price. Spending money on it is quite rational.
Along with them, on sale you can find a great variety of air conditioners manufactured by order of Russian and foreign companies at large air conditioning plants of Chinese manufacturers using the so-called OEM technology (from the English original equipment manufacturer
Many large Russian chains of electronics and household appliances stores and wholesale companies selling household and (or) climate equipment offer air conditioners under their OEM brands, often very well promoted. This technique is usually quite high quality and efficient. However, before purchasing such an air conditioner, the buyer should realize that the same device, perhaps even in a better configuration, can also be bought under the Chinese manufacturer’s own brand, but already at a price 1.5-2 times lower than that stated trading company.
Present on our market (albeit in small volumes, mainly in the regions) are frankly low-grade OEM products that go on sale under hitherto unknown brands (the so-called no name equipment). Such crafts are supplied to Russia by firms with a dubious reputation and even individuals who want to get a «profit» from the sale of air conditioners in the season of maximum demand.
The appearance on sale of low-grade air conditioners at a low price is due, on the one hand, to the flexibility of a Chinese manufacturer operating on OEM technology and ready, at the request of the customer, to minimize the cost of any component or technological stage in the production of air conditioners (for example, use the most inexpensive compressors and electric motors, abandon operations control when assembling blocks and
Pros and cons of inverter split systems
one step ahead
If the grip of poverty in the context of the global world crisis has not yet squeezed your being and consciousness too tightly and you want to buy a really good, efficient climate machine, we recommend that you purchase an inverter split system with a heat pump function that runs on ozone-friendly freon R410A. Inverter equipment on R410A will cost 20
It is characteristic that inverter split systems (more precisely, devices with inverter control of the compressor drive) quickly bring the temperature in the room to the value set by the user and accurately maintain it at this level. BUT
Split systems on R410A freon are equipped with a compressor other than devices on R22. AT
Inverter-type split systems of the same power, operating on R410A freon, are not quite correct to compare with each other only by price: other parameters are also important. It is logical to compare the models of the power you require in terms of energy efficiency, noise level, adaptability to work at low temperatures, the ability to evenly distribute conditioned air throughout the room and, of course, the design of the indoor unit.
Cheap and cheerful
The indisputable advantage of the inverter air conditioner on the R410A can be considered the maximum (in relation to other competing models compared to each other) values of its energy efficiency indicators EER and COP. Data on EER and COP are placed in the device passport. If we divide the cost by 1
If you could not find information about the EER and COP of the device, look at least for data on the category of its energy efficiency (often they are indicated on the packaging). All household appliances, including air conditioners, are divided into seven categories, denoted by letters from A (best) to G (worst). Category A air conditioners have COP > 3.6 and EER > 3.2
In addition to energy efficiency (and, consequently, the cost of operating the air conditioner), it is worth comparing applicants according to the boundaries of the temperature range of operation. It is characteristic that in Russia, in most cases, it is not the maximum temperature on the street that is critical, at which safe operation of the device «in the cold» is possible (although in hot countries air conditioners «sharpened» for extreme heat in a «tropical» version are especially in demand), but the ability to split systems to heat the room and not break down at temperatures below 0
Many sellers claim that it is strictly forbidden to use a split system in cold weather, its breakdown during such operation
The main danger when operating the air conditioner at low outdoor temperatures is the freezing of ice in the outdoor unit. This reduces the comfort of using the device as a result of constant shutdowns to thaw frost on the heat exchanger of the outdoor unit. AT
Among the models of inverter wall split systems on R410A, designed for heating at low temperatures outside the window, one can note wall-mounted air conditioners of the SKVP-ND series in the northern version (
Be careful: counterfeit
We do not recommend buying climate equipment in a one-day company that appeared during a period of increased demand for air conditioners. AT
The most important criterion for choosing an inverter (however, traditional) split system
Noise minimization is ensured by two key points: firstly, an appropriately developed overall design concept, and secondly, the accuracy of manufacturing the moving parts of the components.
Mitsubishi Electric has achieved outstanding success in minimizing noise. For example, the indoor units MSZ-GE25VA of this company have perhaps the lowest noise level in the industry.
When choosing an inverter split system, you should also pay attention to the noise level of the outdoor unit, especially if nervous neighbors live next to you who are used to sleeping with open windows. The fan propeller and outdoor unit guard must be designed to minimize airflow resistance and reduce noise, and the compressor
The power of the air conditioner should fully (but not more than that) meet the needs of your room in cold or heat. An insufficiently powerful air conditioner will work in forced mode and fail faster, and an overly powerful air conditioner will greatly empty your pockets when buying. Estimated calculation can be carried out independently, based on the area of the air-conditioned room: per 1
In our opinion, when comparing the technical characteristics of inverter split systems, one can not take into account the various «gadgets» of such equipment, designed to give it any unique capabilities. So, split-system filters well protect the openwork plates of the evaporative heat exchanger of the indoor unit from coarse contaminants such as poplar fluff and
If you really need not an air purifier, but an air conditioner that can rid the air in the room of tobacco smoke and extraneous odors, pay attention to the technique with electrostatic filters. Similar filters are in the top models of powerful air conditioning brands: Daiseikai (
Many independent experts doubt the effectiveness of split systems as devices for saturating the air with oxygen (the doses of O2 supplied to the room by an air conditioner equipped with an «oxygen generator» are negligible, and such pseudo-ventilation does not solve the problem of removing excess carbon dioxide and other contaminants). This also applies to air enrichment with negatively charged ions (air conditioners are equipped with unipolar ionizers that generate only negative ions, and in the living room, according to the current SanPiNam, both negative and positive ions must be present, the balance of which can only be maintained by a bipolar ionizer), vitamin C particles ( the effectiveness and safety of such «therapy» is generally not scientifically substantiated) and
Alas and ah, the practical uselessness (to put it mildly) of some functions is well understood by many manufacturers, however, this does not prevent them from continuing to equip their equipment with “miraculous healing” innovations, since some consumers make the final choice in favor of a particular model due to the presence of some unique option or their maximum combination…
Well, what to expect in this sense from the Chinese technology no name? It is usually not equipped with any additional devices at all, but at the same time they do not hesitate to lie that the air conditioner is literally stuffed with them! For example, on the remote control of the air conditioner, a button for turning on the ionizer can be installed, and in the indoor unit
… And yet, another user who presses the remote control button and sees that the miracle mode lamp on the air conditioner has lit up will feel the same improvement in air quality. This will happen due to the well-studied placebo effect. A person takes wishful thinking and, without experiencing exactly any physical impact, still miraculously feels it and is healed …
It is hardly expedient to compare air conditioners in terms of functionality. In fact, all the user needs
The energy efficiency of a split system is easy to determine by the letter symbol that you will find on the packaging or nameplate of the device.
Ah, montage, oh, montage!
Our advice to you: hurry up with the installation of the air conditioner before the onset of really hot days, do not postpone its purchase and installation indefinitely. Now for 7-10 thousand rubles. it is still quite possible to find a decent team that will install the equipment quickly, efficiently and with a guarantee. But when choosing performers, beware of scammers who can ruin even the most “advanced” technology in no time. An indicator of the viability of installers can be a certificate of completion by them (or at least one of the members of the team) of courses issued by the APIC Training and Consulting Center (Association of Climate Industry Enterprises).
If you live in a renovated dwelling or you are not going to make repairs in the foreseeable future, but at the same time you are not ready to take a steam bath in the summer without a split system, a complete installation of equipment is most suitable for you. It is usually carried out on the same day when the air conditioner «arrives» in your apartment, by a team of two or three installers. If everything goes smoothly, the specialists will manage in 3-4
Would you like a discount?
What can be saved? Choose last year’s air conditioner model. Functionally, it is sometimes no different from the latest, but the manufacturer gives an additional discount that you can get when ordering an air conditioner online in one or another online store.
Full air conditioning installation, however, is not an ideal solution. The fact is that freon tubes and electrical cables between the units of the device have to be pulled in a plastic box, which does not decorate the home with its appearance. It’s good if the section of the box is small, but sometimes you have to lead it along the wall across the whole room … Branded boxes offered by air conditioner manufacturers look more or less organically in the interior,
In addition, the condensate drain pipe from the indoor unit must be led outside when the air conditioner is fully installed, which can cause protests from pedestrians.
If you are renovating an apartment, it is best to install the air conditioner in two stages. This method will allow you to do without boxes in the interior and at the same time will not affect the decoration of the room.
The first stage of such installation starts before the start of finishing work (plastering, installation of plumbing fixtures and
For laying communications in apartments, installers usually use the space behind a false ceiling (or behind its decorative lowering along the perimeter of the room) or 6
The second stage of installation work on the installation of the air conditioner is carried out after finishing the walls. It involves connecting a bundle of tubes peeking out of the walls to the fittings of the outdoor and indoor units, as well as electrical work. In addition, air conditioner installers must ensure that the plumbers who installed the plumbing connect the condensate drain pipe to the bellows in the bathroom or to the sewer riser (so that the smell from the sewer does not go through the air conditioner into the room, there must be a water lock in front of the riser). Then
If you plan to install a split system in your apartment in two stages, your duties as a customer will include «cultural and educational» work. Its essence is to warn the foreman or teams of finishers, electricians and
