Air conditioning or split system - which is better? Comparative review

Differences in work

The first thing that distinguishes the work of the split version is the complex interaction between the blocks. This is where freon comes into play, which comes from the external module to the internal one. At the final stage, it is blown by a fan - this allows cold air to enter the room. If, on the contrary, the air needs to be heated, the heat pump comes into play. And already the evaporator becomes condensers. Freon is compressed as a result of the operation of the compressor, which is located in the external unit.

Splits can be installed in a variety of places - on the wall, ceiling, and floor. In addition, there are multi-options, the internal modules of which go to different rooms. The difference in the operation of a split system and a monoblock air conditioner is that in the latter, condensate enters a special container. The user must drain this container periodically.In modern two-module systems, this is not necessary - the water will drain itself through a special drainage pipe into the street.

Another significant point that determines the difference between the two types of the same technique is, of course, design. When choosing for yourself - a system or an air conditioner, you must remember that the first one will fit perfectly into any interior, can be presented in a variety of color variations, while manufacturers of the second type are in no hurry to adapt to the tastes of potential consumers (not least because for the functionality of the device).

Design difference

In the subconscious of many, when the term “air conditioner” is mentioned, the image of an ordinary window or over-door monoblock pops up, in which the evaporator and refrigerant compressor are combined in one case, but this is not entirely true. Today, any cooling device is considered an air conditioner - a stationary (window, door), portable (portable) monoblock or a split air conditioner that has become the most popular over the past 15 years.

In production shops, distribution centers, supermarkets, a column unit is used - the most powerful unit in terms of cooling capacity. In office buildings, channel (multi) systems, "multi-splits" are used. All these devices are air conditioners. This concept is collective.

Split system: device features and principle of operation in simple words

Split system is a compressor air conditioner, the parts of which are divided into internal and external units.

The noisy half, which is the compressor and fan, are installed outside the building.

The rest is mounted indoors. Both blocks are interconnected with copper pipes. The work uses a refrigerant.

There are 2 main types of split systems - inverter and conventional. Consider the differences between them, without delving deep into the electronic device:

1. The conventional system operates in start-stop mode. When the set room temperature is reached, the appliance switches off automatically. And if the sensor detects that the temperature has become higher, the device starts up again. With such a scheme, electric motors can often turn on, briefly creating aperiodic starting processes. Although rare, they can still create premature failures.
2. Inverter systems operate in continuous cooling mode with constant fan rotation. They maintain the set temperature with an accuracy of 1 degree, designed to work around the clock. This increases the service life of the equipment by 30-40%. Accordingly, their cost is 2 times more expensive than conventional split systems.

Depending on the external design, split systems are classified into the following models:

• wall-mounted - the simplest and most popular option for domestic use;
• channel - installed in the inter-ceiling space behind the false ceiling;

• ceiling - designed for rectangular rooms. They direct the cooled air flow along the ceiling or wall, distributing it evenly over the entire area;
• floor - differ in versatility and unpretentiousness to the installation site;

• cassette - used in large rooms and mounted in the inter-ceiling space of a suspended ceiling;
• columned - relevant for large areas. They create a powerful stream of air directed directly to the ceiling, which is then evenly distributed throughout the room;

multi split system - several indoor units of different models are connected to one external unit;

The market offers climate equipment for every taste, quadrature and wallet size. A diverse price range depends on additional features and embedded functions. With the help of a split system, it is easy to achieve a comfortable atmosphere in the room.

Among the impeccable technical characteristics, there are still some inconveniences, due to which some people cannot afford to purchase a split system:

• the need to install an external unit, which can not be installed everywhere and not always;
• stationary installation dictates the inevitability of fixing the executive unit to only one room;
• high cost of the equipment itself, installation and maintenance. Cleaning even the indoor unit of a split system is associated with a large amount of dirty work, and the service of the outer part at a height is the lot of specialists.

Comparative characteristics of monoblocks and split systems - table

What is the difference between air conditioning and split system? The article said that an air conditioner is more often a monoblock, but it should be noted that a split system can be called an air conditioner, but not every air conditioner can be called a split system.

The biggest difference is that a split system is an air conditioner divided into 2 parts.

Comparative table of operational characteristics.

As you can see, the first three indicators highlight the shortcomings of monoblocks.

Split systems in relation to the above characteristics win by 100%. Although the wall-mounted monoblock is not inferior in terms of attractive design and compactness.

But monohull devices stand out with three subsequent advantages.

Split systems cannot boast of such advantages. But a cozy microclimate without unnecessary noise and equipment that takes up space in the room is a huge fat plus in favor of the latter.

The cost of both devices depends on additional features and equipment. To say that split systems are much more expensive would not be true. If desired, you can choose options with a minimum set of operating modes for a very reasonable price.

You can also pay a lot of money for a monoblock. For example, a wall-mounted version costs from 60-70 thousand rubles, and a regular mobile air conditioner will cost 20-25 thousand.

If you wish, you can get by with the simplest split system and keep within the amount of 25-30 thousand rubles, along with its installation.

Criteria for choosing a split system

To decide which split system to choose for an apartment or office, you need to understand a little about the features of such equipment:

1. Variety. In this review, we considered only wall models. But there are also ceiling and duct options that are used mainly in offices, as well as floor solutions that are not so functional and convenient, but do not require complex installation, which is optimal for rented apartments.
2. Filtration efficiency. In addition to the classic options where coarse filters are used, manufacturers also produce air conditioners for allergy sufferers. Such solutions trap the smallest particles of dust and microorganisms. Some models offer the function of cleaning the air from foreign impurities and odors.
3. Power. Directly depends on the area of ​​the room. As a rule, calculators are posted on sites selling climate equipment that allow you to accurately calculate the optimal performance of a split system. However, we recommend taking it a little with a margin, because this will have a positive effect on the service life.
4. Noise level. Values ​​in the range of 25-32 dB can be called optimal. If the volume of work drops to 20 dB, then the device is suitable for work at night. But noisy solutions (about 40 dB or more) should be installed in appropriate areas, like open space in call centers, shops or similar premises.
5. Compressor. Standard or inverter. The second one is preferable because it saves energy and lasts longer while providing the same level of efficiency. However, you will have to “vote with your ruble” for such advantages, so choose for yourself.
6. Design. If the air conditioner is ideal in terms of characteristics, but does not fit into your apartment with its appearance, then you should not buy it.And while manufacturers typically paint devices white, other options are available on the market.

Overview of reviews

A split system has long ceased to be a luxury. A large number of buyers use this technique and leave reviews about it. Thanks to them, we can evaluate the quality and other characteristics of the product. For example, all buyers positively evaluate the appearance of all Electrolux air conditioners. But the rest of the characteristics are very dependent on the model. According to customer reviews, the Electrolux EACS / I-09HSL / N3 model is almost silent and cools quickly. The model has many functions: self-cleaning, restart, night mode and others. But in the EACM-14 ES/FI/N3 model, buyers are not satisfied with the dimensions and length of the air duct, but they really like the rest of the characteristics, including the price.

Split system brands Jax are budget. This is what buyers note as a positive moment. In general, they are satisfied with this brand. They note a large number of necessary functions, 5 operating modes, good power. As disadvantages, some users indicate an unpleasant smell, a small number of additional functions, and increased noise.

Gree GRI / GRO-09HH1 also belongs to the class of inexpensive split systems. Buyers write in reviews that this model is the best combination of price and quality. High level of energy efficiency, excellent quality, low noise level, aesthetic appeal - this is what users like.

Chinese Ballu BSUI-09HN8, Ballu Lagon (BSDI-07HN1), Ballu BSW-07HN1 / OL_17Y, Ballu BSLI-12HN1 / EE / EU have proven themselves very well according to user reviews. Among the shortcomings indicate the average noise level, heating below the set temperature by 1-2 degrees.At the same time, there is a serious drawback - after-sales service: in the event of a breakdown after 1 month of work (!) The buyer had to wait 4 months for the necessary parts.

Customers are very satisfied with the Toshiba RAS-13N3KV-E / RAS-13N3AV-E. According to reviews, this is an excellent air conditioner for heating and cooling. In addition, it has a beautiful appearance, convenient dimensions, excellent energy efficiency.

Roda RS-A07E/RU-A07E is in demand due to its price. But reviews say that the low price does not affect the quality of work. There is simply nothing superfluous in the system, but it performs its functions perfectly.

Daikin FTXK25A / RXK25A attracted the attention of buyers with its appearance. This is what is noted in the first place.

The reviews indicate that this is a high-performance split system with a 5-year warranty period. Among the shortcomings is the lack of a motion sensor and other advanced features.

Panasonic CS-UE7RKD / CU-UE7RKD was called a real salvation both in summer and in the off-season: the air conditioner has fast heating and cooling. He is almost silent. It also has a removable front panel that can be washed and disinfected. The technology is doing its job well.

After analyzing customer reviews, experts named the best split systems of recent years in terms of price and quality ratio. They became:

Daikin FTXB20C / RXB20C;

Split system features

The split system is designed to solve the same problem as the air conditioner - to cool the air in the room.The equipment differs structurally, since it consists of two or more parts: for installation inside the room and outside the room. In this case, the blocks are connected by heat-insulated copper tubes.

How the equipment is arranged and works

The split system uses the compressor principle of cooling. The noisiest components - the compressor and the fan - are brought to the external unit of the system, which is attached to the wall on the street. The rest of the elements - condenser, evaporator and filters - are placed in the indoor unit, intended for indoor installation. Typically, the indoor unit is made in a stylish design, so that it can harmoniously fit into the interior.

Depending on the level of equipment, the functionality of different models may vary. The main features of split systems are as follows:

• setting the desired temperature via the remote control;
• remote switching between modes: cooling, heating, ventilation, humidification;
• purification of air masses coming from the street;
• automatic control of the set parameters.

Varieties of split systems

The air conditioning unit can be mounted on the wall, ceiling and floor. Based on these conditions, split systems are divided into types:

wall-mounted - the most popular type in the domestic equipment sector;

columned (they are also floor) - with fastening to the floor;

cassette, channel and ceiling - mounted inside the ceiling.

In addition to the separation according to the principle of installation, this climatic equipment is classified according to the method of operation and power parameters, that is, how efficiently rooms of different sizes will be cooled. So, simple split systems operate in a cycle: the engine turned on - it worked to the desired temperature - it turned off.

Models equipped with an inverter can run continuously, automatically reducing or adding engine power. In addition, inverter split systems do not allow temperature fluctuations, so a person does not have any discomfort during the operation of the device.

In mini-hotels, multi-room apartments, houses and offices, multi-split systems have become widespread. The prefix multi in the name means that it is possible to connect several indoor units located in different rooms to one powerful outdoor unit for air conditioning.

Where the power of a multi-split system is not enough, multi-zone (aka VRV) systems are used. These are industrial grade centralized air conditioning systems. They are suitable for use in hotel complexes, hospitals and office centers.

Functionality

Split system allows you to adjust the temperature with an accuracy of 1 degree

Air conditioners are constantly improving. In addition to adjusting the temperature in the room, new possibilities for increasing comfort appear. Additional functions:

• Auto mode. The device itself controls the mode selection and maintains the temperature at a comfortable level.
• Airing. Only the fan of the indoor unit works, the compressor is off. There is a uniform distribution of air masses in the room.
• Temperature setting. Control accuracy ±1ºС in the range of 16–30ºС. The sensor is installed in the indoor unit or in the remote control.
• The speed of rotation of the fan impeller changes the amount of flow passing through the indoor module and determines the capacity of the air conditioner in m3/h. The minimum flow rate for room coolers is 5 m3 per hour, the maximum is up to 60 m3 per hour.
• The direction of air flow is adjusted vertically by means of horizontal louvers. The plates are fixed in several positions or swing automatically, distributing the air evenly.

When buying an air conditioner, the consumer selects the optimal number of functions to create the most suitable climate and comfort level.

The best wall-mounted split systems

Most often, split systems are placed on the walls of the room. This is the best option for offices and apartments. On the floor, they get in the way and take up space. Under ceilings are expensive, and if necessary, they are not easy to get to. We need different models, buyers have their own tastes and preferences. But the wall option is a priority. The wall-mounted split system serves comfortably, is easy to install, and requires a minimum of consumables. We present the 3 most successful models of this series.

Electrolux EACS-07HG2/N3

The owners of Ballu BSG-07HN1_17Y noted the ease of installation. As noted in one of the reviews: “It was more difficult to dismantle the old ones than to attach the blocks of the new split system.”

The best split system companies

There are dozens of manufacturers of air conditioners on the market today. However, not all of them deserve attention, since many nameless companies produce, albeit cheap, but too mediocre equipment. In this case, which company's split system is better? We can single out the top five. But you need to understand that the division into places here is conditional, and all brands deserve your attention:

1. Electrolux. One of the leading manufacturers of household appliances. Every year, the company supplies about 70 million of its products to more than 150 countries around the world.
2. Ballu. The key direction of this concern is the production of climate equipment for ordinary consumers and corporate clients. The quality of the company's devices has been repeatedly noted not only by customers, but also by awards.
3. Hisense. The case when the phrase "Chinese company" does not carry anything bad.Initially, the manufacturer focused on the domestic client, but the excellent quality allowed him to enter the international market.
4. Toshiba. The Japanese who don't need to be introduced to anyone. Particularly interesting in the assortment of the company is the middle class of split systems. Functionally, it is not very impressive, but in terms of reliability, price and quality, it bypasses competitors.
5. Roda. Manufacturer from Germany - and that says it all. The brand focuses on the production of heating and air conditioning equipment, which allows you to monitor the quality of the entire line of equipment and offer customers innovative solutions.

What is the result

A mobile air conditioner, in its essence, is a device that cannot differ in special power characteristics. However, there is the possibility of cooling, as well as heating the air, but only within the same room. The convenience of mobile air conditioning systems lies in the fact that they can be easily moved around an apartment or house, from one room to another. Therefore, if the question is what to choose in a country-type house, then mobile air conditioners will be the best option.

At the same time, fused systems are characterized by greater functionality; they are no longer portable, but stationary devices. It also features quiet operation and, at the same time, better power. The installation of devices of these types is carried out in order to purify and cool air masses within rooms that differ in large areas. Split systems will work effectively not only within the apartment, but also within the boundaries of restaurants, halls, and so on.Supplied with a convenient remote control with which you can take control of all the functionality of the device.

As for the shortcomings, both the split system and the mobile air conditioner have them. You need to determine for yourself which of them are unacceptable for you. Only after you think carefully, weigh all the pros and cons, you can choose between mobile air conditioner and split system. This choice must be taken with all responsibility and seriousness. It is necessary that the chosen option suits you on all counts, or at least on most of them.
