Maintaining a microclimate in a large residential building or shopping center is not an easy task. Many external blocks on the façade spoil the appearance and impair the strength of the walls. The best solution would be to use multi-split systems. They allow you to cool and heat a large room.

What it is?

The multi-split system consists of a condenser and an evaporator, unlike conventional air conditioners. It is noteworthy that only one external unit is needed to work in several rooms. A multi-zone system can have 25-70 meters of tubing between the outside and the farthest inside. It is noteworthy that each block inside the building is connected to the outside using a separate route. The air conditioning system is much more convenient to operate than separate units for each room.

The principle of operation is quite simple. The outer section contains a container with a cooler, which moves through the tubes and makes the air cooler. The system can work for cooling or heating. In this mode, the liquid also evaporates in the outer part, and the condensation process takes place in the indoor unit.

Advantages and disadvantages

The multi-split system is more sophisticated than a conventional air conditioner. In the latter, one outer block is mapped to one inner block. And in a multi-split, the outer section implies the use of a large number of inner ones.

The main advantages of such systems

  1. You can install blocks in different rooms. It is possible to choose the appropriate section for a particular room and not overpay for a standard one.
  2. An individual microclimate can be set in each room. For example, you can raise the temperature in the bedroom and lower the temperature in the kitchen.
  3. The multi-split works quietly. The sound comes only from the outdoor unit, which can be moved away from the windows of the living quarters. It is worth noting that in simple air conditioners, the installation of the units is always linear, which means that it will not work to reduce the noise level.

The multi-split system also has disadvantages

  1. The indoor units will not work if the outdoor unit breaks down.
  2. Different rooms can be set to different temperatures. However, the heating or cooling mode is set on the outdoor unit and cannot be changed.
  3. For the installation of the system, you need to invite experienced craftsmen with the appropriate tools. It is impossible to install the system yourself.
  4. The cost is much higher than that of simple air conditioners.

Varieties and equipment

Systems are conventionally divided into fixed and type-setting. The first one is sold as a ready-made set of 2-4 indoor units and one outdoor unit. The fixed system in the outer part has a certain number of inputs for communications and connection of internal components. The outdoor unit can be equipped with one or two blowers, which determines the performance of the system . Indoor equipment is always fitted with only one such device.

Modern systems with two compressors allow different operating modes to be set on the indoor units. Each device will work independently of the other. This possibility is inherent only in fixed types of systems.

Each indoor unit has a separate control panel. In this case, all units can work either for heating or for cooling.

Stackable multi-split systems can include up to 16 indoor units. The splitter of the circuit, to which the cooling liquid goes, allows you to connect them all to the outer part of the structure. The outer section can have up to 3 blowers that work together. The working conditions for this type of system do not differ from the fixed ones . You can either heat the air or cool it down.

Cold mode can be combined with dehumidification. They are similar, so it is safe for the system. It is noteworthy that you can install any number of indoor units, all restrictions are due to the capacity of the outer section. The type of interior is selected individually for the parameters of each room.

The typesetting system can consist of different types of outer sections. Combinations are possible with any number and configurations. There are several types of internal parts.

  1. Wall mounted . Most home appliances look like this. The usual and most accessible type.
  2. Floor and ceiling . Visually reminiscent of batteries and can be installed both above and near the floor.
  3. Simple ceiling . Outwardly, it resembles a kitchen hood.
  4. Cassette . Installed during renovation directly into the ceiling. The advantage is that the air is supplied in 2-4 directions at once.
  5. Duct . Like the previous type, it is mounted during renovation. Air enters the room through the grate.
  6. Column . Allows you to regulate the microclimate in a large room.

Each set has remote controls for control. One is configured as a master and is intended for system debugging, control. All the rest are assigned the "slave" statuses. The main console allows you to set the mode for all indoor sections. The rest are designed to adjust the temperature regime on each air conditioner.

Usually a fixed multi-split system is enough for an apartment . Suitable sets are chosen for a large private house. It is worth noting that some types of blocks are installed even at the stage of rough repair work, so it is important to think about this aspect in advance.

Column air conditioners are not used in residential premises. Usually they are installed in warehouses, in halls of philharmonic societies and in industries where the square of the premises is really large.

How to choose?

The multi-split system is suitable for a 4-room apartment, home or office. When choosing, you should be guided by certain criteria.

  1. Dimensions of the room . The larger the room, the larger the indoor unit will be.
  2. Number of rooms . This nuance directly affects the power of the outer section.
  3. Track length . This is the distance between the outdoor unit and the indoor unit. The smaller the footage, the easier the installation is. It's worth noting that long runs can hide power.
