Split block. Internal blocks of split systems. The price of stationary monoblocks
Greetings to all readers of the site "All about air conditioners". Today I will tell you what parts the indoor unit of a split system consists of, and why each of them is needed. 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 features. To understand them, I have a separate article dedicated to. But today we will analyze the most common type of air conditioner in houses and apartments - a wall-mounted split system.
Details of the indoor unit of the 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 (it is also an evaporator, it is also a heat exchanger). It is called an evaporator, because in the cooling mode, freon evaporates (boils) inside its tubes. Based on this process.
The size and shape of the evaporator largely determines the (cooling capacity) of the “split”. The more powerful the air conditioner, the larger its radiator should be. Such an element is a tube crossed by thin plates (similar to lamellae). Freon moves through the tubes at a certain temperature. And the plates increase the heat exchange surface area, which significantly affects its efficiency.
Manufacturers are improving (complicating) the shape of the radiator and its plates in every possible way. 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. Radiators of modern air conditioners have an antibacterial coating, which in some way prevents the reproduction of viruses. But since such trifles are not visible from the outside, almost no buyer pays attention to these things. But in vain!
Shaft (fan)
In order for the radiator to quickly and efficiently cool the room, it is necessary to “force” the air through it. This is helped by the shaft (aka fan, aka 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. In most models, the radiator, as it were, outlines the shape around the shaft. This design combines the most efficient heat transfer and ergonomics (allows you to make a compact indoor unit).
Motor (motor) shaft
The shaft of the indoor unit is driven by a motor. It is located to the right of the fan and is controlled by the board (I will 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, the so-called drainage tray is used (it's also a bath, it's also a pallet). For some air conditioners, it is connected to the body, but in most
designs it is removable. Together with moisture, all dust and pollution is collected in it. Therefore, it is much more convenient to flush and maintain this tray when it is detached from the body. The front lower part of the radiator, as it were, lies in this tray and the condensate from the radiator flows directly into the bath. Most often, water is brought out into the street through.
Horizontal and vertical blinds (blinds)
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 regulate the flow up and down. Behind them are vertical blinds, which are several "petals". They regulate the flow from right to left. All these curtains are attached under the drainage tray. When servicing, they are removed together with the tray. They are driven by small motors.
Control unit (board) with sensors
In order to synchronize (coordinate) the work of all parts, a so-called control unit (the “brains” of the air conditioner) is located inside the case. They manage all nodes. This element is a board to which "power" is supplied. All wires, starting elements of engines and sensors are connected to it. This board is located on the right side of the indoor unit case.
The operation algorithm of this unit is guided by 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 heatsink temperature sensors are the most important parts of the board. Their readings form the basis of the process of maintaining the exact temperature in the room.
Filters
Mandatory element of a modern air conditioner are its filters. They are located on top of the evaporator under the revision cover of the housing. Mesh filters "collect" the main part of the dust. They can be removed and washed very quickly, which allows you to keep the evaporator clean longer. In addition to mesh filters, 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. It represents an equally important detail, since in order to create modern interior can not do without a compact and spectacular design.
From the considered trifles, the quality of the final product is formed - in our case, the air conditioner. The more modern each detail, 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!

A multi-split system is an excellent choice for offices, shops, private houses and large apartments where there is a need for air conditioning in several rooms at once. Such climatic equipment differs from conventional wall-mounted air conditioners in that here several indoor units are connected to one external unit with an inverter compressor, separated by different rooms. This allows not to clutter up the facade of the building and maintain a comfortable microclimate throughout the facility.
Peculiarities
The advantages of multi-split air conditioning systems include the following:
- Preservation of the aesthetics of the facade of the building
