Indoor units of multi-split system. All about the outdoor unit of the air conditioner 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 option - units are mounted in a 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 regular 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 internal installation, there will be only one external one.

This article will not talk about all monoblock air conditioners, which, by definition, do not have external units, that is, they are air conditioners without an external unit. This is a wide segment of climate control 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 it has advantages:

• Absence of an external block on the wall of the building.
• To install them, you do not need to obtain permission to install an external unit. Sometimes this is not possible.
• There are no freon lines and no need for rolling connections. If rolling is of poor quality, freon may leak. The dependence of installation quality on the qualifications of installers is eliminated.
• Simple installation that is almost impossible to mess up.
• Modern design. Large selection of block colors.
• There are models with an influx of outside air. The influx of the stationary monoblock is equipped with filtration, recovery and heating systems for 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. You need 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 outwards. Insert two air channels into them. Install external grilles.

Channels, patterns and grilles are included in the package of a stationary monoblock - an air conditioner without an external unit. A remarkable system for installing gratings that does not require work at height. The gratings are simply made flexible. They are carefully pushed out and then unbent, closing the hole. A special cable is tied to the air conditioner body and secures the open grille

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

About the tightness of the wall-mounted monoblock

The freon circuit of an 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 announced as one of the advantages.

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

Then the air conditioner needs to be recharged. 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 is not just about monitoring the amount of freon. It is necessary to clean and check the serviceability of heat exchangers and fans. Clean the drainage system. Check temperature conditions and electrical connections.

Condensate removal system (drainage system)

The condensate must be drained outside through the air pipe of the air conditioner without an external unit. Some of the condensate evaporates. The one that does not evaporate spills out through the grate and can spoil the wall finish. This means that the drainage process cannot be considered resolved.

Here (as with a split), you need to think about the method of drainage and not disturb the finish of the wall outside. That is why the air conditioner kit without an external unit contains drainage pipes, and its design includes a hole for drainage.

Quiet operation?

The noise characteristics of wall-mounted monoblocks are from 32 dB to 42 dB. For a unit installed indoors, this is noisy. Modern outdoor units of split systems of similar power operate with such acoustic parameters. But with splits this part is taken outside. Therefore, for air conditioners without an external unit, the model range is limited to a cooling capacity of 3.5 kW.

The noise from a model with a higher cooling capacity would not allow their use in domestic premises. However, the manufacturer claims that the design of the air conditioner is changing and quiet models are appearing.

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 several 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 case when there is no permission to install an outdoor unit, it is impossible to install it, or there is no possibility of laying a pipe route to install other equipment.

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 that 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 indoor air conditioner operates silently, but the outdoor unit makes a loud noise. The permissible noise level is 33 dB.

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. This type of climate control equipment differs from conventional wall-mounted air conditioners in that here several indoor units, separated into different rooms, are simultaneously connected to one external unit with an inverter compressor. This allows you to avoid cluttering the façade of the building and maintain a comfortable microclimate throughout the entire facility.

Peculiarities

The advantages of multi-split air conditioning systems include the following:

• Preserving the aesthetics of the building facade
• Ease of use and ease of maintenance
• Possibility of using different indoor units
