Split system: what is it, how to choose, what varieties are found
Split systems are somewhat different from standard air conditioning units. The term “schism” implies division. This means that the air conditioning functions are divided into two different units that are interconnected. One of them is an external unit, which is located outside and serves to cool gases, and an internal unit, where air at a comfortable temperature has already appeared sale of air conditioners carried out by the Climate Factory company, here you will find ventilation systems, split systems, heating devices.

Inverter split system: what is it?
The operation of an inverter split system is based on converting alternating current into direct current, and then again into alternating current, but at the desired frequency. This approach allows you to regulate the engine rotation speed. This allows more precise control of the entire device. Inverter technology reduces energy costs and allows the air conditioner to be used at much higher outside temperatures.
Inverter types are characterized by efficiency
Inverter systems have their advantages and disadvantages. Let’s go over the positives first:
- Significant reduction in the number of components;
- Faster process of transition to the required temperature;
- Less noise;
- Longer service life.
Well, the downsides:
- Higher price compared to classic systems;
- Requirements for the absence of voltage surges;
- Difficulty finding similar spare parts during repairs.
Multi-split system: what is it?
In essence, a multi-split system is a more advanced and convenient version of a conventional system. The prefix “multi” here means that there are several indoor units. This is important for creating a comfortable temperature in some living rooms or office spaces. Thus, one outdoor unit works with several indoor units. An air conditioner with a multi-system can be purchased for about 30, 000-40, 000 rubles.
Multiple devices can be connected, including different types
What is the difference between an air conditioner and a split system
The main difference between a split system and an air conditioner is that the former is a derivative of an air conditioner. In other words, this is an extended version. Due to the fact that the cooling process itself is technically divided into two devices, the indoor units can be placed in convenient locations. And this opens up wide opportunities for developers in terms of design and design features of the air conditioner.
Split system air conditioner
As mentioned earlier, the split system is divided into two blocks – internal and external. Let’s take a closer look at what each of them includes and what responsibilities they perform.
Schemes of operation of split systems
External unit
It is usually placed outside the room: at the entrance, on the roof or directly on the balcony. It is connected to the indoor unit by a line with flouns and electrical connections. External devices include compressors, capacitors, piping systems, receivers, various relays and boards. There are also fans installed outside the building, but you can rarely hear them in the rooms.
Indoor unit
The types of indoor units differ both structurally and in design. Therefore, they can be placed on the ceiling, walls or floor. Depending on the “sulphur” of the system, the device may contain remote control mechanisms, air filters, timers and other electronics that make the device more convenient to use.
The principle of operation of the split system
The operating principle of the air defense system is very simple. External units contain a compressor, inside of which there is a cooling gas – floun. It passes through a system of tubes to the indoor units and cools them. Thus, the air passes through the cooling stage occupied by the indoor unit and passes through a system of radiators connected to tubes. Some systems can not only cool, but also heat the air. Indeed, this is only possible at external positive temperatures.
Main types of split systems
According to the scope of use, all split systems can be divided into three main types:
- Home Mainly used in apartments, houses and small offices. Low power. The emphasis in such devices is mainly on appearance, with a design that easily fits the air conditioner into the existing interior;
- Commerce. They can be installed in houses of this type, but most often they can be found in large offices and houses with a large area;
- Industrial. They offer high power, capable of creating a comfortable temperature in large spaces, retail spaces, production facilities, etc. The design of such units is usually very simple. More attention is paid to power and functionality.
Structurally, segmented systems are divided into five categories. They differ in design, capabilities, and their advantages and disadvantages.
Wall-mounted
The most affordable and popular type. It can be installed in virtually any room up to 70-80 m². This type of unit offers a wide range of color and design options and can be installed in virtually any interior. The ease and speed of installation, as well as the low cost, have positively impacted the popularity of this type. Some minor drawbacks should be noted: limitations in power and installation space.
Manufacturers strive to give wall-mounted air conditioners a more user-friendly appearance.
Duct
The best solution for cooling multiple rooms simultaneously with a single air conditioner. Air is distributed through special ducts located under a suspended ceiling. They increase power sufficiently for moderate-temperature areas. Among the disadvantages is the inability to set individual temperatures for each room. This requires the installation of special additional devices and thermostats.
When using ducted designs, this is not particularly important.
Cassette
The indoor unit of this type of split system is a kind of cassette, which is conveniently integrated into a suspended ceiling. Even its dimensions correspond to the standard ceiling size of 60 x 60 cm. Grilles and ducts are located on four sides of the cassette, ensuring even air distribution throughout the room. These models are typically placed in the center of the room for more efficient cooling. One disadvantage is the requirement for a suspended ceiling.
Cassette systems can be very easily integrated into existing structures.
Floor-ceiling
As the name suggests, this type of split system can be installed on ceilings and floors. This is usually achieved by reducing the height. Installation can be designed so that the air flow is not directed at people, while still serving its intended purpose. The obvious advantage of this type is the freedom in choosing the installation location. The downside is that nothing can hide his presence in the room.
“Amateur” type of floor flow.
Columned
As a rule, this is a huge cabinet that looks like a refrigerator. It does not have an elegant design and is used to cool critical areas. It is therefore equipped with a high-performance air conditioning system. Among the negative aspects, it is worth noting the low compatibility with interiors and large sizes.
The row types are very large.
Advantages and disadvantages of split systems
Let’s analyze all the information about split systems and find out what pros and cons they may have. The entire process of installing a split system air conditioner can be considered suspicious advantages. There is no need to place an external unit. There is also no need to seriously change the appearance of the facade. Indoor units can be placed anywhere. It all depends on the available budget and imagination. At the same time, different types can be integrated into different rooms or spaces, for example, in the kitchen with a wall, and in the bedroom with channels.
One split system can be used to create comfort throughout the entire home
Isolating the noisiest neighborhoods and moving them outside is a smart move. This reduces the overall noise from the air conditioner in the room. Meanwhile, the internal units are “stuffed” with a variety of electronics and various control and filtration systems, which developers use, which makes the devices more and more convenient and functional.
Some of the advantages described may lead to disadvantages. For example, if an outdoor section fails, subdivision can be very frustrating. After all, if you cool several rooms at once, they will all be left without fresh air. The same applies to the inability to set a specific temperature for different rooms. If the air is cooled in one of them, it will not work for heating. The above advantages in the form of a bright installation can unexpectedly turn into quite expensive disadvantages if you need to place the blocks at a large distance from each other.
How to choose a split system – editorial advice
Perhaps the choice of a split system should start with a question. Is this really necessary? Maybe it’s easier to use cheaper and simpler monoblocks?
In general, be wary of split systems if:
- You need a quiet air conditioning system;
- It should fit organically into the existing interior design;
- You need to cool or heat several rooms at the same time;
- You want the split system to be exactly how you want it to be.
If the choice is obvious, all that remains is to decide which split system to buy. It’s worth starting with power. In this case, you can requalify in a maintenance area that is easier to navigate. Moreover, almost all manufacturers indicate this value in the specifications of their devices.
Attention.
When choosing a split system, pay attention to the maximum length of the device’s communications. The design distance from one block to another must be exceeded.
In addition, the indoor units make a little noise. Where it matters, look at the model with the smallest DB value. The designs of split systems are selected individually depending on the situation and interior design. All other parameters, such as ventilation, drainage, the presence of timers, filters and other additional features, are limited only by the budget.
