Split block. External blocks of multi-split systems. Price of stationary monoblocks
Owners of buildings with a large number of rooms, when selecting climate control devices, are increasingly making their choice in favor of the most profitable option today - multi-split systems. The operation of just such equipment makes it possible to optimize electricity consumption, while creating favorable microclimate conditions throughout the entire building. In addition, multi-splits have already received wide demand among owners of business centers and other commercial real estate.
Which blocks to choose?
Indoor units of multi-split systems, like any other semi-industrial air conditioners, come in several types:
- Wall Mount Models
- Floor-ceiling modifications
- Devices for integration into duct systems
- Cassette version - units are mounted in suspended ceiling or suspended from the ceiling on brackets
The most popular among them are wall-mounted devices designed for indoor installation. Their price is usually about the same as that of conventional wall-mounted air conditioners. The set of functions and operating modes is no different - it all depends on the specific model. The only, but very important difference is the fact that, regardless of the number of blocks for indoor installation, there will be only one outdoor one.

The internal unit of a split system performs the main task of an air conditioner - it cools the air in the room. Structurally includes:
· housing with blinds;
· radiator (evaporator);
· fan with electric motor;
· electronic control unit;
· water drainage system.
Additionally, inside the case there are air filters and a container for collecting moisture.
Depending on the design, indoor units are wall-mounted or floor-mounted. As an option - universal, that is, they can be attached to the wall or installed on the floor.
A feature of modern indoor units is the antibacterial coating of the evaporator surface.
Benefits and Features
One of the significant advantages of split systems is their compactness. The indoor unit of the air conditioner takes up little space and fits nicely into the interior of any room.
The air conditioner can operate in cooling, dehumidifying and heating modes. This versatility is especially useful in the cold season when central heating does not work.
The split system is configured and controlled using the remote control. If necessary, the air conditioner operates automatically.
A special coating protects all metal surfaces of the indoor unit from corrosion.
Additional functions of the indoor unit
Each modern indoor air conditioner unit has additional functions:
· accelerated microclimate creation mode;
· protection against icing of the evaporator;
· energy saving;
night mode of operation of the device;
· settings memory;
· permanent (washable) filters.
You can buy the indoor air conditioner unit separately in our online store. When choosing a product, the manager will tell you in detail about all the functionality and help you choose exactly the device that will fully ensure a comfortable microclimate in your room.
Structurally, the external unit of a split system consists of a compressor that compresses the refrigerant, a condenser that performs the task of cooling freon, and a 4-way valve (used in functional systems, which can heat and cool rooms). In addition, it includes a fan that moves air and blows across the condenser, a control board and a system of fittings. The design also includes a grille that protects the devices from insects and foreign objects getting inside. Since the compressor is located in the outdoor unit, this significantly reduces the noise level in the refrigerated room - it is about 24–26 dB.
How to choose an external unit of a multi split system?
The following parameters must be taken into account:
- device dimensions. As a rule, the dimensions of the blocks are 80 x 50 x 30 centimeters;
- power. Selected in accordance with the serviced area of the premises;
- noise level. It often happens that the air conditioner in a room operates silently, but outdoor unit It's buzzing a lot. The permissible noise level is 33 dB.
The company's consultants will help you buy an external split system unit that is most suitable in price and technical specifications and corresponding to technological needs.
Greetings to all readers of the site “All about air conditioners”. Today I will tell you what parts the internal unit of a split system consists of, and what each of them is needed for. We will also analyze the joint principle of operation of all these components.
Many of you know that there are several types of devices for various purposes in industry and everyday life. Each of them has its own design and its own characteristics. To understand them, I have a separate article dedicated to them. But today we will look at the most common type of air conditioner in houses and apartments – the wall-mounted split system.
Details of the internal block of a wall-mounted split system
Evaporator (radiator)
As we know, the most important function of an air conditioner is to cool the room. Therefore, the main part of the indoor unit is the radiator (aka evaporator, also known as heat exchanger). It is called an evaporator because in the cooling mode, freon evaporates (boils) inside its tubes. Based on this process.
The (cooling power) of the “split” largely depends on the size and shape of the evaporator. The more powerful the air conditioner, the larger its radiator should be. This element consists of tubes crossed by thin plates (similar to lamellas). Freon moves through the tubes at a certain temperature. And the plates increase the heat transfer surface area, which significantly affects its efficiency.
Manufacturers are doing their best to improve (complicate) the shape of the radiator and its plates. For simple wall-mounted models, this may be a straight small radiator; for other models, this radiator may have a complex shape that occupies most of the body. The radiators of modern air conditioners have an antibacterial coating, which in some way prevents the proliferation of viruses. But since such little things are not visible from the outside, almost no buyer pays attention to these things. But in vain!
Shaft (fan)
In order for a radiator to quickly and effectively cool a room, it is necessary to “force” air to pass through it. This is helped by a shaft (also known as a fan, also known as an impeller), which creates air movement through the radiator and blows it into the room. This part of wall-mounted air conditioners is a drum with blades. The blades and the shaft itself are designed in such a way as to reduce the noise of its operation. For all wall-mounted air conditioners, it is located under the evaporator. For most models, the radiator seems to outline a shape around the shaft. This design combines the most efficient heat exchange and ergonomics (allows you to make the indoor unit compact).
Motor (motor) shaft
The shaft of the indoor unit is rotated by a motor. It is located to the right of the fan and is controlled by a board (I’ll write more about it below). The motor is fixed with a special casing to the block body.
Drainage tray (bath)
During operation of the air conditioner, condensation (water droplets) forms on the evaporator. In order to “collect” all this water, a so-called drainage tray (aka bath, aka tray) is used. In some air conditioners it is connected together with the housing, but in most
designs it is removable. Along with moisture, all dust and dirt collects in it. Therefore, it is much more convenient to wash and maintain this tray when it is detached from the body. The front lower part of the radiator seems to lie in this tray and condensation from the radiator flows directly into the tray. Most often, water is discharged to the street through.
Horizontal and vertical blinds (curtains)
Any wall-mounted indoor unit has two types of curtains, with the help of which the direction of air flow is partially regulated. Horizontal blinds regulates the flow up and down. Behind them are located vertical blinds, representing several “petals”. They regulate the flow left and right. All these curtains are attached under drainage tray. When servicing, they are removed along with the tray. They are driven by small motors.
Control unit (board) with sensors
To synchronize (harmonize) the operation of all parts, a so-called control unit (the “brains” of the air conditioner) is located inside the housing. They manage all nodes. This element is the board to which “power” is supplied. All wires, motor starting elements and sensors are connected to it. This board is located on the right side of the indoor unit housing.
The operating algorithm of this unit is based on the indicators of temperature sensors, and issues commands to the main components of the air conditioner (compressor, fans and expansion valves), turning them on and off in a timely manner. Thus, the unit controls each element of the split system, maintaining the required temperature in the room.
Air and radiator temperature sensors are the most important parts of the board. Their readings form the basis of the process of maintaining an accurate temperature in the room.
Filters
An essential element of a modern air conditioner is its filters. They are located on top of the evaporator under the inspection cover of the housing. Mesh filters “collect” the bulk of the dust. They can be removed and washed very quickly, which allows you to keep the evaporator itself clean for longer. In addition to strainers, many air conditioners are equipped with other filter elements. Some of them are able to effectively destroy bacteria and viruses - some eliminate odors, and some enrich oxygen with healthy particles.
Indoor unit housing
All of the listed parts are combined and hidden in a single housing. He represents no less important detail, because to create modern interior can't do without a compact and spectacular design.
The little things considered make up the quality of the final product—in our case, an air conditioner. The more modern each part is, the more efficient, reliable and, accordingly, more expensive it is. IN modern world very high competition between manufacturers. Therefore, each of them offers its own technical solutions for a certain price category. This is where I end the article. Leave your comments!
