Split system is the most common air conditioning system among all existing today. A variety of variations of such systems are used everywhere, differ in the method of attachment and the type of device. The key advantage of the split system is that it can equally well be used to create coolness and heat it indoors. Installed in residential premises and at enterprises, they have a lot of positive aspects.
Split and multisplit air conditioner - what it is and how it works
Existing types of air conditioners include indoor and outdoor units. Air conditioners are divided into types depending on the features of indoor indoor units.
The following split systems exist:
- floor-mounted;
- attached to the wall;
- cassette type;
- columned;
- ceiling mounted;
- channel.
Wall-mounted air conditioners are mainly used in living rooms, however, they can also be seen in workrooms.
Strengths of wall-mounted air conditioners:
- a wide range of products from various manufacturers, due to which you can make the right choice;
- the device does not emit noise, therefore it will not break the usual rhythm of life;
- reasonable cost: the system is selected based on family income;
- original design that fits into a room decorated in any style;
- at night, you can turn on the energy-saving mode of the system.
The weak side of a wall split system is considered to be a complex installation, which can only be carried out by specialists.
For offices and large enough apartments it is better to use ducted air conditioners. They differ in power, due to which they can simultaneously make a cool microclimate in three or four large rooms. Mount this system under the false ceiling panels to hide its interior.
Room cooling occurs due to the passage of air through a pipe system located on the ceiling. In an apartment, it is better to fix the main indoor unit where a large ceiling height is not particularly required, for example, in a toilet or pantry.
Channel type of cooling
In other rooms, the system will occupy only 8-10 cm of the ceiling height, where the air duct will be located. Air can be taken not only from the premises, but also from the street. For this, a special hole is made into which the tube is held.
Advantages of ducted air conditioning:
- cooling several rooms at the same time;
- all communications are hidden by the ceiling;
- you can add street air.
A negative characteristic of the equipment is the inability to choose a different temperature mode for each room. The temperature is set by the indoor unit of the air conditioner located in one of the rooms.
Cassette Air Conditioners are installed in rooms where there are always a lot of people. This, for example, entertainment centers, cinemas, concert halls, conference rooms. The system is able to quickly and efficiently cool a large room. All wires and pipes of the air conditioning system are located behind the panels of the false ceiling.
Air conditioning is characterized by the following advantages:
- Fits perfectly into the interior, does not spoil the view, because it is hidden under the ceiling;
- created four directions of movement of cold air;
- communications are covered with a decorative lattice imitating ceiling tiles.
Multi-split air conditioning: strengths and weaknesses
Installation scheme for multi-split air conditioner
Choosing this system is quite complicated compared to standard air conditioners. Simple air conditioners have two units: one is located outside the window, and the second is indoors. The multi-split system consists of one outdoor unit, which is designed for several indoor units.
The positive qualities of multi-split systems are:
- It is possible to install different internal systems in different rooms. You can choose a unit that is suitable for this particular room, as well as save money.
- In each room, you can set your own cooling temperature, create your own microclimate. For example, children set a higher temperature, and in the kitchen, on the contrary, cool more.
- Multisplit hardly makes noise. Only the street part of the system exudes sound, which can be placed away from the windows of the living room. This is convenient in contrast to simple systems, where each internal part must correspond to the external.
Disadvantages of multi-split systems:
- If the outdoor unit breaks, the indoor ones will also not be able to work.
- In each room where there are blocks, you can choose only a different temperature. The heating or cooling mode is activated on the outdoor unit and applies to all rooms without the ability to change it.
- The complexity of the installation work. Only specialists with the necessary tools and experience will be able to do this.

How to choose a system?
The options below will allow you to make the right choice:
- Dimensions of premises. This parameter directly affects the size of the indoor unit: in a large room you need to install a large unit for efficient air conditioning.
- The number of rooms where you need to create air conditioning. This indicator affects the choice of the external unit.
- Power of the external unit. The block on the street should, according to its characteristics, be such that it creates the full-fledged operation of the blocks in the rooms. Deal with this option will help professionals.
- Track length. It will depend on the distance between the outdoor unit and the indoor. It is better that the distance is as small as possible, because then the installation will be easier, and the power of the work will not be lost.
- External constructions. If the outdoor unit should be in harmony with the facade of the house, then the indoor should completely fit the interior of the room
Cassette Cooling Air Conditioner
The disadvantage of such a system will be a high price, as well as a complex and time-consuming installation.
Ceiling and floor air conditioners are installed in large rooms where there are no false ceilings and other types of air conditioning cannot be installed. Most often, these include large rooms with large windows. The described type of devices has a shallow depth (20-25 cm), it is mounted at the bottom of the wall or under the ceiling. Therefore, cold air can spread around the entire perimeter and area of the ceiling, or simply rises.
The positive qualities of the system are the following:
- uniform flow of cold air without damage to health;
- each thread can have its own strength indicator;
- can be mounted in rooms with ordinary, not suspended ceilings;
- you can cool a room of any, even the most original form.
The negative point is only the high price of this type of system.
Column types of split systems can often be seen in large areas where installation of other types is not possible. This, for example, hotels, philharmonic societies, theaters, museums and so on. The system creates a large and powerful flow of chilled air.
The advantages of column systems are:
- You can conveniently adjust the air temperature;
- even very large rooms are quickly cooled.
Air conditioning column system
Of the negative features of the column system, the need for a large-scale area for installing the main unit can be noted.Externally, the air conditioner is bulky, reminiscent of a refrigerator.
Thinking about buying a modern split system, you need to pay attention to all the technical specifications in order to make the right choice. The system must meet the floor space for efficient air conditioning.
Manufacturer's choice
When the type of air conditioner is selected, we proceed to the choice of model. Numerous manufacturers from around the world offer consumers a huge number of models of air conditioners, and sometimes the characteristics coincide, but the prices vary. To make the choice right, it is worth considering which manufacturers represent their products on the market.
Category "economy"
Fairly reasonable prices are exhibited by the Italian company Dantex, the Japanese company Shivaki and the Korean manufacturer Hyundai. The production facilities of these companies are located in China, however, the process is completely controlled by the owner company. To create all types of air conditioners, only the highest quality materials are used. Each company offers consumers many models and ranges, often not inferior in functionality to more expensive and well-known brands.
