Models of multi split systems for 3 rooms

Do you have three independent rooms that need to be cooled and heated? Isn't this great?!

Selection by parameters ( technical requirements) and cost (financial restrictions) trust the professionals - us!

The air conditioner for three rooms is a multi split system with the ability connecting three indoor blocks. As a rule, this is an air conditioner with an inverter, i.e. the possibility of smooth control of the compressor power and, accordingly, a soft, comfortable change in the temperature in the room.

Why do you need a multi split system? Imagine that you have only one place to install an outdoor air conditioner unit: either the facade no longer allows it, or the homeowners association prohibits it, or you yourself don’t want to hang the facade of your building with “birdhouses.” But at the same time, there is an urgent desire to ensure coolness in the nursery, in your bedroom and in the kitchen. Which has higher priority? Why choose if the way out of this situation is to buy a multi-split system for three blocks.

Installation of multi split systems

Installing an air conditioner is quite a responsible matter. And here we do not recommend searching for covens. A multi-split system for 3 rooms is usually installed during the renovation of an apartment or country house. If the system fails, there is a high probability that the civilian team’s phone will simply stop answering. What to do with a low-quality rolling mill from which freon or worse than that- an air conditioner route broken into the wall?! Dismantling all communications during the finished repair is more than a significant amount of money, nerves, and time.

In our practice, it is not uncommon for clients to contact us with a request to complete the installation: check the route, hang the internal units of the air conditioner, perform vacuuming. What is the probability that you will find this team in a year or even two - at the time of completion of your repair?

The operation scheme of such systems is as follows: three indoor units are placed in rooms that correspond to the owner’s wishes, and they are connected to only one unit - the outdoor unit, which is placed on outside building walls. Indoor units placed in this way can maintain autonomy of specified settings and operating modes, being independent of other units.

Control over the operation and control of each of the three units can also be carried out individually, using separate remote controls. This makes such a system simple and comfortable to use.

Relevance of application

Multi-split systems are usually used to avoid multiple bulky structures on the facade of a building. There are several possible situations in which the installation of such a set of equipment would be relevant:

• the façade of the building cannot accommodate placement additional structures;
• installation of outdoor units is limited by the homeowners association or other services;
• The homeowner himself does not want to clutter the façade of the house with many blocks.

Advantages of multi-split system for 3 rooms kits

Technical specifications and the convenient design of these systems have proven themselves in the product market as in demand and reliable. And all because they provide:

• integrity of the facade of the house;
• organic interior of the premises;
• energy savings;
• possibility of simultaneous or partial operation of indoor units;
• convenient way control of each block of the system.

When choosing a multi-split system, you need to take into account that you need to organize the operation of the indoor units in such a way that they simultaneously work either for cooling or for heat. Thus, they will help you ensure a uniform microclimate in different rooms and avoid temperature changes.

note

The cost of a 3-room multi-split system is usually higher compared to individual mono-split systems. This is due to the labor intensity and complexity of the installation process of this set of equipment and communication system.

When choosing such a system, you do not need to save on money for one simple reason: when you finish warranty period outdoor unit, the cost of dismantling and reinstalling it will cost you a fairly round sum - not much, not little, half the cost of the entire set climate control technology.

Multi-split system for 3 rooms

We bring to your attention the most optimal sets of multi-split systems for 3 rooms in an apartment or office space. You should understand the principle of selecting frequently requested sets of multi-split systems for 3 indoor units. Each 3-room multi-split system is completed based on the most common technical conditions provided by our customers, where the main parameters are the volume of rooms, ceiling height, ceiling drop and distance from the external unit to the internal units. Together with the manufacturers, we tried to provide our customers with information on pricing of a multi-split system for 3 rooms, but we ask you to take into account and provide our engineers individual characteristics your residential, office or other premises.

Common mistake when selecting a multi-split system with three indoor units, this means ignoring the total length of the freon route and altitude differences. Selecting a unit based only on the cooling capacity of the indoor units poses a risk quick exit failure of the compressor and the lack of those climatic parameters that were planned at the stage of selecting a multi-conditioning system for 3 units.

For an accurate and professional selection, we ask you to request technical specifications in the operating company, independently or together with our technical specialists, draw up technical task for the selection and installation of a multi-split air conditioner for 3 indoor units.

The BerMiNa Group team makes every effort to ensure that you can purchase a multi-split system for 3 rooms without wasting time, while providing factory prices. We are working to ensure that you can buy the latest new products in Moscow, Krasnodar and Nizhny Novgorod.

Multi-split systems for 3 rooms consists of three indoor units and one outdoor one. Split systems are selected depending on the area of ​​the room. For example, for 20 m2 an indoor unit with a power of 2.0 kW to 2.5 kW is suitable, as a rule, these are the 7th and 9th models, if a room of 30-35 m2 is an indoor unit with a power of 3.5 kW. The length of the route along which freon circulates depends on the distance of the indoor units from the outdoor one. The longer the route, the more expensive the installation. The power of the outdoor unit is selected based on the sum of the power of three indoor units. Manufacturer of multi-split systems for 3 rooms must be reliable and well-known, because if the outdoor unit fails, the entire system does not work. And one more thing you need to know, such systems do not automatically switch from cold to heat, you first need to switch on one of the remote controls in desired mode. Today, such air conditioners are produced as inverter ones - they save energy compared to conventional ones by up to 30%.

Installation of multi-split systems for three rooms

The installation is carried out in two stages: the 1st stage consists of cutting holes, laying a route and installing the outdoor unit. The route must be pressurized. Stage 2 consists of installing the indoor units and checking the entire system.

In this article: the history of the creation of multisplits; their difference from conventional split systems; pros and cons of multisplits; climate systems with one and several compressors; multi-block air conditioner - compare and choose; what should be taken into account when installing a multi-split.

Such familiar and seemingly well-known split systems turned out to be completely difficult - behind the brand, series and price there is more hidden than the natural desire of manufacturers to extract maximum income. It’s simple - if you want the split to supply only cold air, then buy a cheap model, but if you need a truly comfortable atmosphere in the house, then cold air alone will not be enough.

We continue publishing materials about climate control technology - let's talk about multi-splits and find out what kind of air conditioners they are.

One external unit for several internal ones

In the early 30s of the last century, dividing a household air conditioning system into two blocks was not just a whim of the inventors, but a necessity - poisonous ammonia was used as a refrigerant in those years, the leakage of which was unacceptable. With the discovery of a new type of refrigerant - freon - the situation changed, since it was safe for humans. Household air conditioners became monoblock, intended for installation in window openings. Years later, Japanese air conditioner manufacturers returned to the two-unit design - Toshiba developed the first split systems, and Daikin went further, creating in 1969 a household air conditioner consisting of one external and two internal units, called multi-split.

The household version of multi-zone air conditioning systems - multi-block air conditioners - are used for regulation climatic conditions V large rooms, separated from each other by airtight partitions. Since there is only one external block, the covering of building facades with dozens of blocks from split systems, which is typical for our time, does not occur, i.e. the original architectural appearance of the buildings remains unchanged.

Multisplits are produced in two design solutions - with one and several compressors. The number of indoor units for models with one compressor is limited only by the compressor power, i.e. the total power of the hair dryer units should not exceed the power of the external unit (ideally, the compressor power should be approximately 15-20% higher). Buyers are offered multisplits of this type with standard set internal units or future owners of a split system can separately purchase an external unit and then select required amount internal hair dryers to it. Systems with several compressors in an external unit (no more than 3) are designed to work with a limited number of internal units equal to the number of compressors - one compressor for one hair dryer unit. The difference between multi-splits with one and several compressors is that the indoor units in the first type of air conditioning units can only operate in the same mode - either cooling or heating, while the hair dryers of multi-compressor air conditioners operate in modes independent of each other.

Air conditioning systems of this type are equipped with conventional and inverter compressors; indoor units can be wall-mounted, ceiling-mounted, floor-mounted, cassette or ducted. General principle The operation of multisplits is identical to that of household air conditioners of other classes. Models equipped with an inverter compressor have some advantages in terms of energy savings - system electronic control is capable of extracting heat or cold from empty rooms served by a multi-split, transporting them to rooms with increased load on the climate system. For example, if in the summer several people gather in the hall of the house, then the multisplit will take the cold from other rooms (bedrooms, children's rooms, etc.), the climate in which is brought to the level specified by the user. During installation of the external unit, one direction of the refrigerant line is set as a priority - this room will be serviced by the climate control device with special care. Usually this is the room with the largest number of working equipment (for example, a server room) or the constant presence of a significant number of people.

Characteristics of multisplits

Multi-system air conditioning systems are ideal for installation in buildings classified as cultural monuments and houses whose architectural design does not allow for the installation of interior spaces conventional splits - the external block can be placed outside the facade, for example, on the roof. Regardless of the installation location of the outdoor unit, significant space savings are achieved, because for two-block split systems you will need more of it - a multiple of the number of indoor units.

Reducing the number of external units to one reduces the cost of servicing the climate system - refilling with refrigerant, cleaning, preventative repairs, etc.

The user gets more freedom in choosing the power of the indoor hair dryer unit for each serviced room, depending on its area, the number is constant people present and the number of operating equipment.

The power supply only needs to be connected to one external unit - the internal units of the multisplit receive electricity via a cable from the compressor unit.

Inverter multisplits are more economical than two-block split systems with an inverter compressor.

Let's move on to the negative characteristics. The first disadvantage of multi-unit splits is that if the units in the external unit break down, the air conditioning system will fail completely.

All multisplits are more expensive than their corresponding power models with one external and one internal unit. At first glance, this looks strange, since there is only one external unit - the higher price is explained by the fact that the installation of such an air conditioning system is more difficult, taking into account the several times longer refrigerant route, complex circuit channels for condensate drainage and a significant mass of the external unit (over 50 kg). Multisplits are equipped with more complex system control responsible for temperature conditions in each of the serviced premises separately, which requires precise adjustment of the compressor operation and ventilation unit. Also, prices for equipment of this class are regulated by the manufacturers themselves, who prefer to maintain prices for high level to give it more status.

Taking into account the high power of the compressor, the external unit of a multi-split produces more noise during operation than a conventional split.

Choosing multisplit

I propose to study the characteristics of external units, which will not be easy for the buyer to choose - first you need to choose them, and select internal hair dryers after. IN comparative review External units from multi-systems from popular Japanese manufacturers Mitsubishi Electric, Daikin and Toshiba, with equal cooling power, will take part.

(*) - the external unit of any split system is involved in cooling or heating the refrigerant, the ventilation and drying functions are performed by the internal unit(s);

(**) - usually hair dryer blocks are selected for the external multisplit unit at the rate of one block per room. The power of each indoor unit is determined by the size of the room being served, and its location is determined by the interior features of the room.

MXZ-2C52VA, Mitsubishi Electric

Let's analyze the collected information on the external blocks of multisplits:

• Among the models under consideration, the Mitsubishi unit has the highest energy efficiency, i.e. its efficiency is higher than that of the other two;
• The Mitsubishi unit weighs more than the other two - it must be mounted on a reliable foundation ( hollow bricks won't fit). The Toshiba model weighs almost 10 kg less than others; accordingly, fewer requirements are placed on its mounting base;
• the device from Mitsubishi allows you to extend the longest line to it without additional injection of refrigerant;
• all three models are made in Thailand, have the same warranty period and will last approximately the same period;
• the units in question are produced by the largest manufacturers of climate control equipment in the world;
• all units are equipped with inverter compressors, providing efficient work air conditioning systems in heat pump mode;
• only a Daikin brand unit allows more than two indoor units to be connected to it. As a result, the climate system, composed of three internal hair dryers, will create a favorable atmosphere in three rooms isolated from each other at once;
• The lowest cost is the Toshiba brand external unit.

3MXS52E, Daikin

Conclusion: based on the results of the analysis, it is not possible to clearly recognize one of the three models considered as the best, since each of them has unique pros and cons - the Mitsubishi unit consumes the least amount of electricity, the Daikin device is capable of working with three indoor units simultaneously, and the Toshiba external unit is cheaper others, although it is inferior to them in a number of parameters. Final decision remains with the homeowner - what is more important to him, energy efficiency and performance, the number of units in the multi-split system or the total cost of the air conditioning system.

Features of installing multi-split air conditioners

The first and most important task is to decide where to install the external unit. Unlike split systems, the external units of multisplits must be set so that the length of the freon line leading from them to each internal unit does not exceed the maximum allowed by the manufacturer, otherwise the quality of the climate system will seriously decrease.

It is best to install an external unit on the roof of the building, so that it will not “decorate” the facade, and in this case it is much easier to carry out preventive maintenance after the work is completed. If installing the unit on the roof or facade is impossible for some reason (for example, because the freon line is too long), then it is mounted in the attic, balcony or basement. However, placing the external unit indoors is undesirable, because if there is insufficient ventilation, it will overheat, which will lead to frequent system shutdowns and increased wear of the units.

Now about the tubes and wires connecting the multi-split units to each other - installers invariably want to run them along the facade of the building, covering the outside with an unattractive plastic box, because... this is easier to do than running communications through shafts inside the building. If there is a sufficient distance between the blocks, you should insist on a hidden installation of the main line, since it should not be exposed to the changeable external atmosphere.

Regardless of the type of indoor unit you choose (wall-mounted, cassette, etc.), it is necessary to resolve the issue of draining condensate from the hair dryer at the installation stage of the multi-split - ideally, it should be discharged into the sewer system.

To solve air conditioning problems, multi-split systems are more suitable than others if:

• the rooms to be served by the climate control unit are in the process of rough repairs(i.e. without finishing the walls) - laying a freon line into the walls in this case will be cheaper;
• near the serviced premises there is a balcony of sufficient area where you can install an external unit;
• the windows of the rooms where the multi-split indoor units are supposed to be installed face one side of the house - in this case, the length of the pipeline will be the shortest and will not exceed the standards established by the manufacturer.

In conclusion

Focusing only on the cost of the external multisplit unit will be incorrect - depending on the power, the number of functions performed and the manufacturer, the internal units will also cost a considerable amount (on average, the price of one hair dryer unit will be 25,000 rubles).

From the following article you will learn about ceiling-floor split systems, their technical specifications and functional features.
