Type

General type of air conditioner.

Nowadays, on the market you can mainly find split systems, multi split systems, portable devices. More rare options are window models and monoblocks. Here is a more detailed description of each of these options:

— Split system. The most popular type of modern air conditioner. Such models consist of two units — indoor and outdoor. The outdoor unit is responsible for heat exchange with the environment — it is through it that excess heat is discharged (or vice versa, external heat is taken into the room, when working for heating). The indoor units are installed in the room, the conditioned air comes from it. Both units are connected by pipes through which the coolant circulates. Air conditioners of this type are convenient, in particular, because the indoor unit can be installed almost anywhere in the room; and in some models, the indoor units have an unusual design (see below), which allows such devices to fit even into non-standard interiors. Also note that split systems can have almost any performance, among them there are models of both household and industrial levels, and the installation of such air conditioners is relatively simple. All this led to their popularity.

— Multi split system. A kind of split system (see above), in which there are several indoor ones for one outdoor...unit. This arrangement allows using one air conditioner to organize climate control in several rooms at once, while the installation of such a system is easier, and the cost is cheaper than using separate split systems.

— Portable. Air conditioners made as a single unit, designed for the possibility of frequent movement from place to place; in some models, wheels are even provided for this. For heat exchange with the external environment, such devices use air ducts that lead out of a window, doorway, ventilation shaft, etc. A mobile air conditioner can be a real salvation where it is not possible to install a stationary device: it does not require complex installation work, just figure out where to bring the duct pipe. In addition, such a unit can be useful in a situation where you need to cool several rooms in turn, and it is difficult or impossible to install a stationary air conditioner for this purpose.

— Window. Air conditioners made as a single unit, installed directly in the window opening — so that one side of the device is indoors, the other is outdoors. It is one of the first types of air conditioners, but, nowadays, it is considered obsolete and rare — mainly due to the complexity of installation and a very limited choice of installation locations. In addition, such an assembly inevitably covers part of the window, which in some cases is also a serious drawback.

— Monoblock. Stationary air conditioners in the form of a single unit with wall installation. Such a unit is located inside the room, on the wall facing the outside, and heat exchange is provided by air ducts passed through the wall, through which the outside air enters the heat exchanger and exits it. Such a design allows you to do without outdoor units, which is very convenient in some situations — for example, if an air conditioner is needed for a historical building or house in a strictly defined design that does not allow unnecessary "decorations" on the facade. On the other hand, monoblocks are expensive, and the possibilities for their installation are very limited.

Nominal capacity BTU

The British Thermal Unit (BTU) is used to indicate the rated capacity of air conditioners in cooling mode. The parameter is indicated mainly for split and multi split systems with wall installation. Capacity is indicated in BTU per hour, while 1 BTU/h is equal to about 0.293 watts. The rated capacity of an air conditioner is often a multiple of 1000 BTU. The indicator determines how many thousand BTU/h the air conditioning equipment provides. For example, the marking "9 BTU" here means a unit for 9000 BTU/h or about 2600 watts of effective capacity.

The practical meaning of the capacity is that by BTU you can easily determine the recommended area of a standard room in square meters: just multiply the figure indicated in the characteristics by 3. So, for 9 BTU it will correspond to 9*3=27 m². Note that there is no strict relationship between BTU and watts in this list: for example, air conditioners with an effective capacity of 2360 to 2900 W fall into the same category of 9 BTU. In practice, even such an approximate ratio is enough to understand which air conditioner should be considered for cooling certain area.

Recommended room area

A very conditional parameter that slightly characterizes the purpose by the size of the room. And depending on the height of the ceilings, layout, structure of the building and equipment, the actual values ​​​​may differ significantly. Nevertheless, this item represents the maximum recommended area of ​​​​the room for using the air conditioner in the main mode – for cooling.

Most often, this parameter is indicated by a simplified formula: about 100 W of effective air conditioner power is required per 1 m2 of room area. Thus, for example, for a model with a cooling capacity of 2200 W, the recommended area will be 2200/100=22 m2. However, these results are relevant only for standard conditions in residential and office premises: ceiling height of about 2.5-3 m, no strong heat gain, etc. For more specific situations, there are more detailed calculation formulas, that can be found in special sources. Anyway, choosing an air conditioner according to the recommended area, it's ok to take a margin of at least 15-20%: this will give an additional guarantee that the device will be effective.

The recommended area up to 15 m2 for a modern air conditioner is considered very low; such units are designed to serve single rooms of a small area. For an average living room like a bedroom or living room, a 20 m2 or even 25 m2 model is better suited. Models of 30 m2 and above are already intended for at least studio apartments, and more often for office and industrial premises. And in the most powerful modern units, the recommended area can be 150 – 175 m2 or even more.

Note that the same general formula is used for the heating mode — “100 W per 1 m2”. At the same time, the effective power of most air conditioners in this mode is noticeably higher than in the cooling mode. So this item can also be used to select a unit with a heating function: an air conditioner capable of cooling a room of a certain area is almost guaranteed to be able to heat it (taking into account the relevant restrictions on the use — see "Operating modes").

In box

A set of components included in the delivery of the air conditioner.

This parameter is indicated only for split and multi split systems (see "Type") — other types of air conditioners are made as single units, and there is simply no need to specify the complete set for them. Split system can be supplied both in a complete set, and in separate units (both indoor and outdoor). Among traditional split systems, the first option is the most popular: it is most convenient to buy such a solution as a ready-made kit, and the purchase of a separate unit is required if one of the original units breaks down. But the components of multi split air conditioners, on the contrary, are most often sold separately — this makes it easy to assemble such a system for a specific situation by separately purchasing an outdoor unit and the required number of indoor ones.

Number of indoor units

The number of indoor units supplied in the kit.

Split and multi split systems are divided into outdoor and indoor units (see "Type"). And the number of indoor units in the kit depends on how many rooms the air conditioner can serve out of the box. However, this parameter is more of a reference than practically significant. So, in a complete set (see "In box") split systems are supplied with one indoor unit. And in the multi split system, a complete set is rare and usually includes two such units; it is assumed that for the organization of a more extensive system, it is more convenient to purchase an outdoor unit and separately purchase the required number of indoor ones for it. Separate indoor units of multi split systems are also sold one by one.

Filters

Types of additional filters that are standard on the air conditioner (in addition to the simplest mechanical cleaning filters, which are found in all models).

We emphasize that we are talking specifically about the filters supplied in the kit; Some models allow you to separately purchase additional elements for air purification, but this possibility is not taken into account in this case. As for specific options, the most popular in modern air conditioners are ionizers, various antibacterial filters(including catechin elements and UV lamps), devices for fine cleaning (including HEPA filters), antifungal, antiallergenic, deodorizing and formaldehyde filters, and also elements that combine several functions at once (for example, catalytic). Here is a detailed description of each of them:

— Ionizer. The action of the ionizer is based on the saturation of the air with negatively charged ions. They provide a feeling of fresh air, have a bactericidal effect, and are considered beneficial for overall health. One of the advanced types of ionizers are also plasma (electrostatic)...filters. Along with the saturation of air masses with useful air ions, they are assigned the task of air purification. Such filters can quite effectively destroy harmful microorganisms, destroy some harmful substances, and trap grains of dust, smoke, soot, etc. — these particles, under the influence of ionized air, themselves acquire a charge and are attracted to the filter plates.

— Fine cleaning. This term usually refers to advanced mechanical filters that provide air filtration at a microscopic level. The specific effectiveness of such devices may vary; it should be clarified separately in each case. Note also that the HEPAs described below are also, in fact, fine filters; however, they use a specific operating principle and are inherently highly efficient. Therefore, the presence of HEPA filters is indicated separately.

— HEPA filter. A special type of mechanical fine filters. Thanks to the special design of the microchannels through which air passes in such a filter, such devices can trap particles much smaller in size than the size of the microchannels. For comparison, the effectiveness of a HEPA filter is assessed by its ability to capture contaminants measuring 0.1 - 0.3 microns (with such particles, such a filter is least effective), while the size of most bacteria starts at 0.5 microns. Based on their effectiveness, such filters are divided into classes; Nowadays, HEPA classes from 10 (retains at least 85% of the mentioned particles) to 14 (filtration efficiency reaches 99.995%) are relevant.

- Catechin. In fact, it is a type of antibacterial filters described below, created on the basis of catechins - natural organic substances with a powerful antioxidant effect. Such filters are highly effective in fighting bacteria and viruses, but they are not cheap; In light of these features, they are separated into a separate category.

- Catalytic. Most often, this term refers to photocatalytic, or “zeolite” filters - devices that operate using a special substance (photocatalyst) and UV radiation. Under the influence of such radiation, the catalyst decomposes the organic matter falling on it into simpler substances - usually water and carbon dioxide. This technology not only allows you to remove harmful impurities from the air (at the level of individual molecules), but also provides a good bactericidal and antiviral effect. Moreover, such a filter requires virtually no maintenance: the photocatalyst is not consumed during operation, and the reaction products freely evaporate outside. On the other hand, the price of such elements is quite high.

- Antibacterial. Various filters designed to destroy bacteria and other harmful organisms - viruses, fungi, etc. The specific operating principle, level of efficiency and maintenance rules for such filters may vary; these details should be clarified in the documentation for the air conditioner. However, if air disinfection is of fundamental importance to you, such a filter will definitely not be out of place. Let us note only two nuances in this regard. Firstly, catechol elements are usually not included in this category, although they have the same purpose (see above); secondly, not every antibacterial filter is capable of effectively fighting viruses - again, it would not hurt to clarify this point separately.
It is also worth considering that no matter how effective the air conditioner filters are, thorough air disinfection is not its main task; specialized devices should be used for these purposes.

- Antifungal. A specialized filter for removing harmful fungi from the air, such as mold. The antibacterial devices described above also have this function to one degree or another; however, this type of filter is much more effective in this regard. On the other hand, the need to intensively fight specifically fungi does not arise so often, and for other cases, the same antibacterial filters are usually quite sufficient. So antifungal elements are used quite rarely in modern air conditioners.

- Anti-allergenic. Filters designed primarily to remove allergy-causing contaminants from the air: pollen (including from indoor plants), dust mites, particles of pet hair, etc. The specific operating principle of such filters may vary and should be clarified separately. Thus, relatively inexpensive air conditioners usually use simple mechanical cleaning, and the term “anti-allergenic” is more of a marketing ploy than a real description of the filter’s specialization. More advanced models often include more advanced technologies - for example, an enzyme filter that breaks down allergens into simple, harmless substances like water and carbon dioxide.

- Ultraviolet lamp. A lamp that processes the air passing through the air conditioner with UV radiation. This treatment provides a bactericidal effect: ultraviolet light neutralizes most bacteria, viruses and fungi. True, in general the efficiency of such lamps is not particularly high; however, they are a great addition to an antibacterial filter. And even without such a filter, the quality of air purification of an air conditioner with a UV lamp will be higher than that of a similar model without such a lamp.
We would like to emphasize that this function should not be confused with the catalytic (photocatalytic) filter described above - UV lamps have a much simpler design and operating principle.

— Deodorizing (charcoal). A specialized filter designed, among other things, to combat unpleasant odors. Acts at the molecular level, allowing ordinary air to pass through and absorbing molecules of substances that create unpleasant odors; Of course, it is also capable of trapping larger particles, such as smoke. Activated carbon is most often used as a filter element - hence one of the variants of the name; There are filters based on other substances, but they also have similar properties. It is worth keeping in mind that in any deodorizing filter the working element must be changed periodically - when its resource is exhausted, it becomes useless and can even emit harmful substances itself.

- Formaldehyde. A specialized filter for removing formaldehyde and some other harmful organic compounds (for example, ammonia, benzene and/or hydrogen sulfide) from the air. The source of such substances can be both external pollution (for example, emissions from industrial enterprises) and some objects in the room itself: new furniture or curtains, some types of floor and wall coverings (immediately after application), spoiled food, cigarette smoke, etc. n. The specific operating principle of filters of this type may vary. Most often, the so-called cryocatalytic element is used, in which the catalyst decomposes organic matter into simpler, harmless components, and then restores its properties due to the cold when the air conditioner operates for cooling. In addition, many catalytic (photocatalytic) filters (see above) have similar capabilities, so one such element can be declared in the characteristics as two types of filters at once - both catalytic and formaldehyde.

In addition to the varieties described above, other types of filters may be found in modern air conditioners, in particular:

— Air purifying. A general name used for different types of filters. This term often denotes the simplest elements of coarse cleaning (for advertising purposes - so that the list of filters in the characteristics is larger). However, there is also another option - devices created on the basis of specific proprietary technologies and which do not fit into any of the varieties described above; such devices can combine several functions simultaneously (for example, fine filtration and antibacterial effect).

— Dust collecting. Most often we are talking about a simple mechanical filter that traps dust and other relatively large particles. Almost all modern air conditioners are equipped with such devices, but in some models the presence of “dust” filters is specified separately - mainly for advertising purposes.

— With vitamin C. A filter that saturates the air with vitamin C. It is believed that this supplement has a positive effect on immunity and skin condition; There is no clear evidence of this, but in conditions of vitamin deficiency, such a device will definitely not be superfluous.

- Preliminary. Mechanical coarse filter installed in front of the main set of filters. Detains relatively large contaminants, preventing them from reaching other filter elements and removing part of the “load” from them. At the same time, the design of the pre-filter is, as a rule, as simple as possible, and its maintenance is limited to periodic shaking or washing.

— “Ionic” (for example, Smart Ion, etc.). As a rule, it is the same electrostatic filter (see above), but presented under one or another brand name.

Power consumption (cooling/heating)

Power consumption of the air conditioner in cooling and heating mode; for models without a heating mode, only one number is given. This parameter should not be confused with the effective capacity of the air conditioner. Effective capacity is the amount of heat that the unit can "pump" into the environment or the room. This item also indicates the amount of electricity consumed by the device from the network.

In all air conditioners, the power consumption is several times lower than the effective capacity. It is due to the peculiarities of the operation of such units. At the same time, devices with the same efficiency may differ in power consumption. In such cases, the more economical models usually cost more, but with continued use, the difference can quickly pay off with less electricity consumption.

Also, two points related to electrical engineering depend on this nuance. Firstly, power consumption affects power requirements: models up to 3 – 3.5 kW can be connected to a regular outlet, while higher power consumption requires a three-phase connection (see below). Secondly, the power consumption is needed to calculate the load on the mains and the necessary parameters of additional equipment: stabilizers, emergency generators, uninterruptible power supplies, etc.

Cooling capacity

The heat output of the air conditioner when operating in cooling mode, in other words, the amount of heat energy that the unit can transfer from the room to the external environment when operating in this mode.

In general, cooling capacityup to 2 kW for modern air conditioners is considered very modest, 2–3 kW is low, 3–4 kW is medium, 4–6 kW is above average, and in the heaviest and most productive models this figure can be 6–8 kW and even more. Also, the conventional unit BTU can be used to denote capacity; in our catalogue, 1 BTU corresponds approximately to 0.293 W, however, for the convenience of choice, some deviations are allowed: for example, the 7000 BTU category includes units with power from 1.8 to 2.3 kW. Also on sale you can find air conditioners for 9000, 12000, 18000, 24000 BTU and more.

As for the choice for this indicator, the simplest formula is as follows: at least 100 W or 1/3 BTU of thermal power should fall on 1 m2 of the area of the room. Thus, to estimate the maximum area served, the power in watts should be divided by 100, and the power in...BTU should be multiplied by three. However, all these calculations are relevant only for standard residential/office premises with a ceiling height of about 2.5-3 m. For other conditions, you need to use a more complex formula, which is the sum of three parameters: 1) Q1 - the heat gain of the room itself, calculated by multiplying the area of the room by the height of the ceilings and the heat transfer coefficient (it ranges from 30 to 40 W, depending on the conditions); 2) Q2 - heat gain from operating equipment (on average, a third of the total power of all electrical appliances); 3) Q3 - heat gain from each person (from 100 W for sedentary work to 300 W for heavy physical exertion). More detailed recommendations regarding such calculations can be found in special sources.

A special case is represented by separately sold outdoor units of air conditioners (see "In box"). In this case, the capacity in cooling mode is the highest heating capacity of the indoor unit (in the same mode, of course) that can be connected to this outdoor unit. For multi split systems, respectively, the total indicator of all indoor units is taken into account.

Heating capacity

The power provided by the air conditioner in heating mode. It is indicated by the amount of thermal energy that the air conditioner can "pump" from the external environment into the room when operating in this mode. The most modest modern units have a heating capacity of 2 – 3 kW or even less, in the most performant it reaches 6 – 8 kW or more.

When evaluating this capacity, the same formulas are relevant that are used in calculating the power of traditional heating. So, for the full heating of an ordinary residential or office space (with ceilings of 2.5-3 m and normal thermal insulation), a thermal power of at least 100 W is required. There are more detailed calculation rules that allow you to calculate the necessary characteristics for other conditions. And if we are talking about a separately sold outdoor unit (see "In box"), then the meaning of this parameter is somewhat different. It indicates the maximum power of the indoor unit that can be connected to this outdoor unit to work in heating mode. For multi split systems, respectively, the total capacity of all indoor units is taken into account.

Recall that most air conditioners are not designed for use as full-fledged heating systems. However, such a unit can be a good addition to the main heating system. At the same time, air conditioners are less expensive than el...ectric heaters: the heater has an effective power equal to energy consumption, and the air conditioner consumes much less energy than it supplies to the heated room.

Also note that the unit BTU (more precisely, BTU/hour) can also be used to indicate the effective capacity (including in heating mode). 1 BTU (BTU/h) initially corresponds to 0.293 W, and the numbers in the characteristics of air conditioners correspond to thousands of BTU/h. For example, a 7 BTU air conditioner will produce an effective capacity of 7000 BTU/h, or about 2 kW. Such marking is convenient because BTU can easily determine the recommended area of a standard room (in m2): just multiply the figure indicated in the characteristics by 3. So, in our example, the power of 7 BTU will correspond to an area of 7*3=21 m2.
