Split block. Internal blocks of split systems. Which blocks to choose

Updated: 10-04-2019

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
Ease of operation and ease of maintenance
Ability to use different indoor units
Wide range of mounting options
Low noise level due to the presence of only one source
Savings on electrical work
High energy efficiency
Application versatility

Modern inverter multi split systems can work for cooling and heating, they are reliable and functional.

The indoor unit of a split system performs the main task of an air conditioner - it cools the air in the room. Structurally includes:

housing with shutters

radiator (evaporator);

a fan with an 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 version, 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 surface of the evaporator.

Advantages 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. Such versatility is especially useful in the cold season when the central heating does not work.

Configuration and operation of the split system is carried out using the remote control. If necessary, the air conditioner operates automatically.

Special coating protects everything from corrosion metal surfaces indoor unit.

Additional functions of the indoor unit

Each modern indoor air conditioner unit has additional features:

· the accelerated mode of creation of a microclimate;

protection against icing of the evaporator;

· energy saving;

night mode of operation of the device;

settings memory;

Eternal (washable) filters.

You can buy the indoor unit of the air conditioner 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 provide a comfortable microclimate in your room.

Structurally, the external unit of the 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 that can heat and cool rooms). In addition, it includes a fan that moves air and blows around the condenser, a control board and a system of fittings. Included in the design and a grill that protects the fixtures from getting inside insects and foreign objects. 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 outdoor 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. It is selected in accordance with the serviced area of the premises;
noise level. It often happens that the air conditioner in the room works silently, however outdoor unit hums a lot. Permissible noise level - 33 dB.

The company's consultants will help you buy an external unit of a split system that is most suitable for the price and technical specifications and corresponding to technological needs.

Building owners with a large number rooms, choosing climatic devices, are increasingly making their choice in favor of the most advantageous option to date - multi-split systems. The operation of just such equipment makes it possible to optimize the consumption of electricity, while creating favorable microclimate conditions in the entire building at once. In addition, multi-splits have already received wide demand from the owners of business centers and other commercial real estate.

What blocks to choose?

indoor units multi split systems, like any other semi-industrial air conditioners, there are several types:

Wall Mount Models
Floor and ceiling modifications
Devices for integration into the duct system
Cassette version - units are mounted in suspended ceiling or suspended from the ceiling on brackets

The most popular among them are wall devices designed for indoor installation. The price for them, as a rule, is about the same as for conventional wall-mounted air conditioners. The set of functions and modes of operation does not differ - it all depends on 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 article will not talk about all monoblock air conditioners, which, by definition, do not have outdoor units, that is, they are air conditioners without an external unit. This is a wide segment of climatic equipment (windows, rooftops, mobile and stationary monoblocks), like all air conditioners, which serves to maintain the microclimate in the room.

Advantages of a stationary monoblock air conditioner

And he has advantages:

The absence of an external unit on the wall of the building.
For their installation, you do not need to obtain permission to install an outdoor unit. Sometimes this is not possible.
Lack of freon lines and the need for rolling connections. With poor-quality rolling, freon leakage is possible. The dependence of the quality of installation on the qualifications of installers is excluded.
Simple installation, which is almost impossible to mess up.
Modern design. Large selection of block colors.
There are models with an influx of outside air. The inflow of a stationary monoblock is equipped with systems of filtration, recuperation and heating of the outside air. But the volume of supplied air is small (up to 30 m 3 / h).

Pros and cons of installation

Installation of a wall-mounted air conditioner without an external unit is really simple and does not require highly qualified installers. It is necessary to make holes in the wall according to the pattern for attaching the air conditioner plate and cut two holes with a diameter of 160 mm outward. Insert two air channels into them. Install outer grilles.

Channels, patterns and grilles are included in the package of a stationary monoblock - an air conditioner without an outdoor unit. Remarkable is the installation of gratings that does not require high-altitude work. Lattices are simply made flexible. They are gently pushed out, and then unbent, closing the hole. A special cable is tied to the air conditioner body and fixes the open grille

In the renovated premises, in order not to spoil the interior, the outer holes are cut using the technology of dry diamond drilling (the drill is not cooled by water). Water is not allowed. She will definitely ruin the finish. The cost of two such holes (depending on the thickness and material of the wall) is slightly less in relation to the cost of installing a split system. Yes, and it will not work completely cleanly. Dust will still get into the room no matter how powerful the vacuum cleaner that cleans it.

About the tightness of the wall monoblock

The freon circuit of the air conditioner without an external unit is evacuated and charged at the factory. The circuit is sealed and sealed, freon leakage is impossible. The system does not require maintenance. This is advertised as one of the benefits.

In fact, freon leakage will still occur. Freon is very volatile. It goes into any microcracks. And, if there was no factory defect, these cracks form after several years of service.

Then the air conditioner needs to be topped up. But there are no valves for refueling. In this case, the copper tubes are cut and freon is added to the circuit. The quality of this work depends on the qualifications of the specialist.

Maintenance Savings

The statement that stationary monoblocks do not require maintenance is incorrect. Maintenance does not consist only in controlling the amount of freon. It is required to clean and check the serviceability of heat exchangers and fans. Clean out the drainage system. Check temperature regime, electrical connections.

Condensate removal system (drainage system)

The condensate must be drained to the outside through the air pipe of the air conditioner without an outdoor unit. Part of the condensate evaporates. The one that has not evaporated pours out through the grate and can spoil the wall finish. This means that the process of drainage diversion cannot be considered resolved.

Here (as with a split) you need to consider a method for draining drainage and not disturbing the wall finish from the outside. That is why the air conditioner kit without an external unit contains drainage tubes, and its design has a hole for draining the drainage.

Quiet operation?

Noise characteristics of wall monoblocks - from 32 dB to 42 dB. For an indoor unit, this is noisy. Modern outdoor units of split systems of similar power work with such acoustic parameters. But in splits, this part is taken out into the street. Therefore, for air conditioners without an external unit, the model range is limited to a cooling capacity of 3.5 kW.

Noise from a model with a higher cooling capacity would not allow them to be used in domestic areas. However, the manufacturer claims that the design of the air conditioner is changing, quiet models are appearing.

The price of stationary monoblocks

How much does an air conditioner cost without an external unit. The price of equipment is still high.

Here are examples of prices for inverter models:

Models ON/OFF:

For this money you can buy some very good split systems.

It turns out that a stationary monoblock, often inferior to split systems and other types of air conditioners in terms of technical characteristics, is a good compromise option in the event that there is no permission to install an outdoor unit, it is impossible to mount it, or there is no way to forward a pipeline to install other equipment.
