Consider productivity, energy efficiency, temperature modes, as well as what additional functions should be at the device.
What is called split system
Split-system - air conditioning, separated by two blocks, internal and outer, which are connected by a copper pipeline for feeding refrigerant. This design is a good compromise between low-cost monoblock air conditioners and highly efficient multi-split systems. On the one hand, the split-system is devoid of shortcomings characteristic of monoblock air conditioners, namely low efficiency and high noise level when working (the noisy compressor is deposited beyond the dwelling). On the other hand, the cost of split-systems is much lower than that of multi-split-systems close to them on the efficiency, in which several internal external blocks are joined to one outer block.
For 20-30 thousand rubles. You can buy quite high quality air conditioning. Therefore, for small (one - three rooms) apartments and summer cottages Split system is the optimal option.
After installing air conditioners, do not forget that the internal blocks are equipped with a system of filtering elements that need periodic cleaning and, possibly, replacing the consumables. It is necessary to produce regular service, otherwise the air purification will be ineffective
What parameters need to be considered when choosing
Performance
This concept includes cold performance (in cooling mode) and heat (in heating mode), as well as the range of outdoor temperatures, in which the air conditioner will effectively work. Therefore, choosing a split system, you must decide in advance exactly how you are going to use it:- To cool the air or also for heating during the cold season;
- year-round or seasons (for example, in the summer in the country);
- As the main or additional heating device.
For seasonal use, almost all air conditioners are suitable. But with heating, they can be wrong. Not so good. On the economy and temperature modes of the device, you can learn from the description of the manufacturer. Productivity on cold (heat) is indicated for air conditioners in kilowatts or in British thermal units per hour, BTU / h. These values are easily comparable: 1 W is 3,412 BTU / h.
The required productivity on cold and heat is calculated for each particular room, based on its volume, windows area, insolation degree, the presence of heat release sources and a number of other values. Simplified adopted recommended performance equal to 1 kW per 10 m² of room area.
Energy Efficiency
Now in Europe (and at the same time, we have moved to a simpler and understandable energy efficiency system, from A +++ to F. The most economical split systems, for example, with a cooling capacity of 2500 W consume only about 500 W electricity; A +++ models are in the assortment of Panasonic, Fujitsu, Haier, Daikin, LG, Samsung and some other manufacturers.
With rare use, the energy efficiency of the air conditioner does not matter. But with year-round exploitation of energy, a lot is consumed (for example, a 2 kW device, working in a year of 200 days to 8 hours, spends 3200 kW / h, by about 16 thousand rubles. According to the current tariffs), and the cost-effective air conditioner may well recoup the costs of Acquisition is pretty quickly.
Temperature mode of operation
For the air conditioner, the minimum outdoor temperature is indicated at which it can operate in cooling mode and in heating mode. Most models are capable of working at a street temperature not lower than -10 ... -15 ° C. There are, however, models specifically adapted to Russian conditions capable of working in heating mode at street temperatures up to -20 ° C and even up to -30 ° C. Such models are in the Fujitsu assortment (Airlow Nordic series), Panasonic (Series "Exclusive", Ballu (Series Platinum Evolution DC Inverter Series), Mitsubishi Electric.However, there is a difference between the minimum street temperature, in which the air conditioner is capable of working in principle, and the minimum temperature at which it works more or less effectively. The same series "Exclusive" in Panasonic is capable of functioning at -30 ° C, but it will only have effective work at a street temperature -20 ° C or higher. It is the minimum temperature that the air conditioner will work effectively, and it is necessary to navigate to this characteristic when choosing an air conditioner for year-round operation.
Noise level
The reservation of the most quiet air conditioners is growing. For example, the noise level of models in the Deluxe Slide series (Fujitsu) is 21 dBA, in the ArtCool Mirror series and Platinum Evolution DC Inverter (Ballu) - only 19 dBA. For comparison: the minimum allowable noise level for residential premises at night is 30 dBA.
In most cases, the low noise level is ensured by the inverter control system of the compressor motor.
Why inverter technology is important
Inverter technology allows you to change the frequency of rotation of the compressor engine. In the usual air conditioner, the compressor always works at one power, and the necessary performance on cold and heat is achieved due to constant inclusions and compressor shutdens. Such a mode of operation leads to strong equipment wear, in addition, the inclusion of the compressor at full capacity is accompanied by a noticeable noise. Inverter conditioners are economical, work almost silently and wear-resistant (and, accordingly, will serve for a long time). Therefore, despite the higher cost, such air conditioners gradually displacing traditional models.

Additional options
Many air conditioners are equipped with highly efficient air purification systems from dust and all kinds of contaminants. Such models successfully replace air purifiers, air washing and similar devices. Mechanical filtering systems can be supplemented with other components. Or it may be an electrostatic cleaning module. To delay the smallest particles of pollution in them, a high-performance electrostatic filter is used, capable of cleaning up to 300 m³ of air per hour.
Some split systems are equipped with powerful ultraviolet lamps to suppress the vital activity of pathogenic microorganisms
New features in modern air conditioners
Built-in Wi-Fi and remote control
Today, the ability to control through the smartphone is found in the Top Lights Ballu, LG, Mitsubishi Electric, Samsung, Zanussi and some other manufacturers. In addition, the built-in Wi-Fi allows you to make remote diagnostics if necessary.Comfortable air flow control
In many modern models, the position of the guide distributors of cold air flows can be changed remotely, using the control panel or through the same Wi-Fi.
Remote control allows you to adjust the operation of the indoor unit, even if it is high under the ceiling
Accelerated cooling and heating
Intensive modes of operation can be ensured due to the increased surface of the heat exchangers or, let's say, like LG, due to more powerful compressors. And in the air-conditioned Samsung, the intensive air exchange is carried out at the expense of the enhanced body shape (if you look at the case on the side, you will see that it has triangular outlines) and additional V-shaped fan blades running the air through the heat exchanger.How often the device needs to be cleaned
Many air purification filters require regular maintenance. Therefore, it is best to make sure that the design of the air conditioner provides simple and easy access to all these elements of the filtering system.
Do not forget about the convenient location of the outdoor and inner blocks of the air conditioner in the house. The internal unit, for example, should not be closed with furniture or other objects, and the outer block is not recommended to be placed on the sun. For an outdoor unit, it is also possible to require a condensate disorder that has formed during the hot season.
In some models, the function of the evaporator self-cleaning is also found (located in the inner block).
Cleaning the inner block
Types of internal blocks
Internal blocks are separated by design on wall, ceiling, wall-ceiling, floor, channels. Wall blocks were the greatest distribution, among which it is much easier to find the desired model for technical specifications. The remaining options are used, as a rule, forced when for some reason wall mounting is impossible.
We will especially select the channel internal blocks that have the advantage that the inner block is removed into the duct channel and does not spoil the interior with its own type (only the output lattice of the air duct).
However, recently, manufacturers have become more attention to the design of interior blocks. Elegant models with thoughtful design appeared, such as the Artcool Mirror series and Artcool Gallery Series, Premium Series in various color solutions at Mitsubishi Electric, special "children's" rules with images of cartoon heroes and other options.
