Overview of the market of channel air conditioners - devices providing optimal temperature, humidity and air mobility.
Plasma filter air purification. Air is passed through a section with a voltage of 4800 V. As a result, all microorganisms are dying, impurities and smells decompose to harmless components
In the living room or dining room heat dissipation is especially high, so there is a powerful channel air conditioner, capable of bringing the cooled air into different areas of the room.
Devices providing in the house the optimal temperature, humidity and air mobility, and, together with them, a good mood and well-being, should be minimally rushing into the eyes. It is likely that this principle was followed by the creators of the channel air conditioners - the most imperceptible climatic devices for a person.
Channel conditioner - a type of split system (from English Split-split, divide). Just as most of its fellows, consists of two inner and external blocks, which are connected to each other with copper pipes and control electrical communications. The outdoor unit is installed outside the served room - on the street: on the wall, on the balcony, on the roof or in the garden, and sometimes in the attic or in the basement. The inner air-processing unit of the channel air conditioner is mounted in the apartment is secretive, unlike internal blocks of split systems of all other types. Moreover, it can be conditioned by air not only in one, but immediately in several rooms. Remind you in the apartment of the channel air conditioner will be fixed on the walls or on a tail ceiling air intake (suction air from the rooms) of the grille and air distribution diffusers through which air-conditioned air is entered, and a compact Wall-mounted control panel installed in one of the served rooms.
Just like every household air conditioner, this device provides cleaning, cooling or air heating, drainage and ventilation in the size of the room. However, channel air conditioners compared to split-systems of other types, capable of creating a higher quality microclimate in the rooms. We mean that in apartments where sealed windows are used with double-glazed windows, fresh air access is practically stopped and ventilation must be improved. Some of some models of the tubules specialists are able to solve the tasks unique to the world for the world: to achieve full-fledged air ventilation, humidification and air ionization. The equipment allows you to achieve the same temperature and air speed even in the rooms of a complex geometric shape. Thus, with proper use of channel split systems, the Customer receives an installation, the functionality of which is comparable to the possibilities of professional central air conditioning systems, but at a price comparable to the price of household air conditioners.
True, all this is real only in the case of proper design and installation of the system with the "channel" and when taking into account the characteristics of each particular conditioned room (orientation on the sides of the light, the wind rose, the type of glazing, the geometry of the rooms and the height of the ceilings, the features of internal heat sources, etc. d.). So the whole range of design and commissioning should be carried out by specialized organizations that have sufficient experience in installing air conditioners of this type.
With the proper use of such a device, you can save significantly. For example, for cooling air in three rooms and a kitchen with a total area of 65-80m2, only one "duct" with a capacity of 7-8 kW and worth $ 2500-4500 will be required. Close-old option is to install four Wall-type split-systems with a capacity of 2-3.5 kW, which, depending on the brand, will cost $ 4500-6000. The advantages of the channel air conditioner will be even more apparent if it is necessary to serve 5-10 small rooms, such as a bedroom with an area of 10-12m2 each. Cooling capacity requires a cooling capacity of 1-1.2 kW, but there are no split systems with a similar productivity. The apack canal conditioner is selected, based on the total required power, there will be no problems with it. While traditional wall-mounted split systems for apartments have a minimal performance of 1.8-2.7 kW, that is, it will have to reboot in power almost twice.
In addition to the explicit merchandise of channel air conditioners, there are several problems faced by their owners. First, the noise from the internal blocks is 25-45 dB, depending on the design, power and other characteristics. Secondly, for the installation of equipment and gaskets, the air ducts requires a certain volume of the room, although slightly, but still reducing the living space (though, mainly on the soldier). Thirdly, it is not always possible to use one or another model of the channel air conditioner for the supply of fresh air. Fourth, the automation of most models of channel air conditioners does not allow you to install an individual temperature in each of the served premises. In general, the "channel" either cools, or heats the air in the room, focusing only at the temperature in the "reference" space, while in rooms with other values of the heat of heat (guests came, the sun looked into the windows, the wind blew) may be too It's hot or too cold.
However, all these problems relate to the category of solvable. There would be money, and manufacturers will offer their technical moves. The range of channel air conditioners presented in the Russian market is extremely wide with dozens of model rows, including products of different power and configuration. If we talk about specific trademarks, then the first thing is to note the technique of American companies Carrier and York. The demand for Daikin, Fujitsu General, Hitachi, Mitsubishi Heavy, Mitsubishi Electric (Japan), LG, Samsung (South Korea) is constantly increasing. Often buy products from Panasonic and Sanyo (Japan), as well as cheaper Israeli products Tadiran, Electra and technique produced in Russia from Elemash.
Recycling or ventilation?
Getting started to choose a channel air conditioner, you must first answer the question of how it is supposed to use it. That is, the device is needed for air conditioning: in one or two adjacent rooms, in one hundred percent recycling mode (in other words, all air will be closed from the room, cool and return back); for the entire apartment or cottage, in the mode of one hundred percent recycling; For the entire apartment or cottage, in partial recirculation mode with a substitution of fresh air (split-system with supply ventilation for year-round use). The last option is the most difficult. On the base of the channel air conditioner, it is required to create a really working air conditioning system and air ventilation. In this case, one internal unit will serve all the rooms at once. It takes street air (for ventilation, on SNiP, 3m3 is required for each tenant per hour per 1m2) and recycling air out of the room, cleans the mixed stream in the air filter, cools or heats and returns back to the room. Excess air (in the amount of influx) due to the channel air-conditioned overpressure is removed from the apartment through the hood in the bathrooms and in the kitchen. The knotted air duct, as well as the insulated channel of supplying fresh air from the street, and the insulated air conditioner to the air conditioner to fit the thermal insulated ducts from the rooms) from the rooms.In the basic supply of the channel air conditioner, the external unit corresponding to it by power and the siper of the internal block, as well as the automation system, includes the external unit. Equipment for systems with 100% recycling, as a rule, includes an external unit with an axial fan and an internal unit with a low, medium or high-pressure fan. To heal the flow in such systems, they are used, as a rule, only the possibilities of the refrigeration machine (reversal of the refrigeration cycle and operation in the heat pump mode). The "duct" for air conditioning and supply ventilation may include an external block with an axial or centrifugal fan or an external water-cooled unit of the capacitor, as well as an internal unit with a medium or high-pressure fan, which is included as a regular element or a separate section. Block of electrical or water calorificates (10-20% of the cost of the split system). In the "cold" models, heated fresh air or its mixture with recycling air is often provided by adjustable electrical or water heaters. On the models with a reversing cycle, heating is performed by the machine in the heat pump mode (they say the thermal pump) up to a noticeable decrease in the performance of the refrigeration machine (by 10-15%), after which heaters are gradually connected to the heating of the stream. If the temperature on the street was equal to the limiting temperature of the specific model, the refrigerator turns off, and the heating is provided exclusively by heaters. Water heaters are more often used in cottages, connect to the heating boiler, which must have the appropriate power supply (usually enough from 10 to 30 kW). If allowed in desperate, then in urban apartments there is a variant of connecting water heaters to the heating system through a plate heat exchanger.
From the point of view of reducing the initial costs of climation of an apartment or cottage, the air conditioning system and supply ventilation system on the base of the channel air conditioner is quite promising. After all, you can refuse to buy an independent supply installation with your own automation system and from laying additional air ducts. But not every model of the channel air conditioner can be used for year-round ventilation of the premises. To do this, it should be implemented the possibility of installing at the inlet to the inner block of the mixing chamber, which pre-stirred in the desired proportion of fresh and recycling air. The maximum amount of inflow is calculated in accordance with the design features of the mixing chamber and is indicated by the manufacturer as a percentage of the total volume of the airborne air. For example, for the Aran JX model from Carrier, fresh air volume can reach 25%, for air conditioners from Sanyo- 15%, etc.
However, the primary value for the operation of the channel air conditioner in ventilation mode has not so much features of the mixing chamber as the pressure characteristics of the inner block fan. This fan must create a sufficient air stream to overcome the aerodynamic resistance of the reverse and supply network of air ducts, as well as resistance to fresh air duct. Another important condition for the successful operation of the "tube" as an air conditioner with the supply ventilation, especially in the regions with a cold climate, is its ability to bring a sufficient amount of heat to the air stream. This will allow air conditioning in a laid cold (for Yalta it is from 0 to -3c, for Moscow -26c and below) maintain the temperature in the supply air ducts at the level of the recommended SNiP 14-16C.
Case in pressure!
Internal blocks with low-pressure fans (maximum pressure of 50 Pa), which in the market the overwhelming majority are practically not used to supply fresh air, and operate on recycling, cooling or heating air indoors. They are able to function with a network of inverse and feed air ducts, the total length of channels of which does not exceed 5 m, and can effectively condition air within one room, including complex shape (long and narrow, with niches, etc.), or in Two adjacent rooms. Models with a cooling capacity of 3-5 kW have a height from 180mm and noise level 26-30 dBA (at low fan speed). This allows you to use them not only in the corridor, but also in rooms where people are constantly located, such as in the living room, in the kitchen and in other rooms where intensive air cooling is required. The exception is except the bedroom.
Models S. Average (within about 70 to 150 Pa) and High-pressure (250-400 PA) fans Can work in recycling mode (both for one to two and for several rooms) and serve fresh air. The increase in the pressure entails an increase in block dimensions (height is somewhere from 300 to 560mm), noise (often over 35 dBA) and the cost of the device, however, allows you to use longer air ducts - at 250 Pa Total length of the network can reach 15-20 m , and sometimes more. In general, the length of the ducts connected to the internal unit is determined by the calculation, the initial data for which is the diameter or the ratio of the lengths of the parties (when using rectangular channels), the material of the air ducts, the number of turns, local narrowings and extensions, etc. To simplify the approval of the pressure with Resistance to air ducts, in air conditioners provide for the ability to change the pressure (for example, Daikin). In order to avoid noise discomfort, the average and especially high-pressure equipment is recommended to install only in the corridor, storage room or other non-residential room, and the network of air ducts is based on heat and soundproofed air ducts (for example, DEC).
Heating
In models of channel air conditioners operating in the mode of one hundred percent recycling, cooling and air heating are almost always ensured only by the refrigeration machine. Monteport (cold) models are operated exclusively in the summer until the air temperature becomes below 14C. Reversible internal blocks that can carry out cooling or heated air are operated in summer, as well as in spring and autumn, while the outdoor air temperature drops below -5C. Under the same minimum temperatures, it will remain working and created on the basis of "bare" (without heaters) of the reversing blocks with partial recirculation - all year round, it can effectively function only in regions with a soft subtropical climate. However, the reversive air conditioner can be used to heal air and at lower outdoor air temperatures. In the case of the lower temperature limit of the operability of the channel split system will be determined by the design of the external block (we will talk about it below).Another way to expand the temperature range of the channel air conditioner is equipped with an internal blocks of air heaters, in the cold, complement or completely replacing the refrigeration machine. Such an approach is most often used in systems with partial recirculation, which mix air.
Internal block models, in the manufacturer's housings, a spiral electric heater is built into the factory, which gives cold models of reversing blocks and provides reversible models with the ability to operate at lower outdoor air temperatures, produce, for example, the Russian company Elemash (model range of KB3), Mitsubishi Electric (Mr. Slim model) and Delonghi (Senior). However, the power of the built-in electrical heaters at most models of internal blocks with a cooling capacity of up to 12 kW is 2-4.5 kW. If in the southern regions of such power, it is enough that the amount of fresh air supplied to the SNiP, then in the colder to withstand the norm is not always possible.
More flexibly to the issue of equipping channel blocks with built-in heaters, Clivet (Italy), Airwell (France) and some others are suitable. In addition to the "professional" channel air conditioners with a cooling capacity of 7 kW with electric or water heaters embedded at the factory, they offer instruments with individual sections of heaters, the range of thermal power in which is significantly wider. The required power is set to the order, it significantly facilitates the selection procedure of the indoor unit. Such equipment is particularly widely used in regions with a cold climate, in systems with partial air recirculation systems.
"Tough" suspended ceiling
There is an erroneous opinion that it is necessary to lower the ceilings in all rooms of the apartment to the height of the indoor unit (30-60cm). But neither for systems with one hundred percent recycling, nor for systems with a shelter of air of such victims is not required. Loss of room height may occur only at the installation site of the internal equipment.
In the general case, the internal unit serving either the entire living area of the apartment or cottage, or one or several rooms, is usually located where the height loss will be practically invisible. Opened, in the attic of a country house, in a storage room or a dark room, on the aness of the city apartment or hidden, behind the tail ceiling in the corridor or in the toilet. Well, and it is almost always possible to stretch the air ducts from the block to the room in the cavity in the cavity of a tail ceiling, which is not more than 10-15 cm in residential rooms, or between carriers enclosing structures and falsely (if any). At the same time, in the room (on the ceiling or walls), only the covering outlets of the air ducts into the room decorative air distributors and air intake grilles will be visible.
In cottages, on the last floors of urban apartments, as well as in old houses, the natural extractor is often ineffective or not working at all. When installing a channel air conditioner with supply ventilation, this can lead to the effect of clapping doors arising due to a significant difference in the air pressure inside and out of the apartment. This case uses a special network of exhaust channels, communicating with air conditioned rooms and with the street. In the end of the exhaust network, in front of the air emission on the street, the centrifugal exhaust fan is mounted. Air emission is carried out through the hole in the wall and the inertial grid, installed outside and the playing role of the check valve. When the fan is opened, it is open when stopped-closed. To reduce the noise distributed through the air ducts from the exhaust fan into the room, the tubular or plate silencer is placed in front of the noise source.
Internal blocks that provide air conditioning and supply ventilation are installed either in the corridor where all the rooms of the apartment or country house come out, or the internal block and all its "air ammunition" will be fully fit for a suspended ceiling. The air intake in the block will be carried out without air ducts, from the space behind the suspended ceiling, in which the air will be separated from the corridor through the ceiling air intake panel. The apodium prepared by the indoor air unit into the room will be made on insulated air ducts, through the air grids over the leaders in the corridor doors. Recycling air from the rooms will be returned to the corridor through a pulp grille in the floor at the floor level, after which, gradually heating, starts up to the air intake panel.
Internal blocks operating in the mode of one hundred percent recirculation and serving one room, also not always require the device of a false-brake in all rooms, it is enough to create a local decrease in the ceiling at the inlet to the room, on the side surface of which to place air distribution devices. Internal blocks are often mounted in closed with decorative screens of suboofer niches or rashlock.
Noisy "Hermit"
In the external block, installed outside the service served, the most noisy equipment "tubular", operating under high pressure, is a compressor, heat exchanger, receiver, separator of the liquid, as well as the elements of automation and protection of the air conditioner. All this is used to prepare the refrigerant supplied to the heat exchanger of the indoor unit. The noise level of the external unit can reach 45-60 dB and more. But this is not scary, because on average, the distance from the external unit to the internal is about 8 m in height and 25 m along the length for the models of a cooling capacity of 5-7 kW and up to 30 m in height and 50 m to the total length of communications - for more powerful models . Internal blocks with axial fans, cooling capacitor, are most commonly used. This kind of equipment is available in all manufacturers of channel split systems, for example Carrier companies (USA), Daikin, Panasonic (Japan), LG, Samsung (South Korea), Haier (China), "Elems" (Russia), etc. . In general, the case, as noted above, such equipment efficiently and safely functions to heating to -5c. The down-step versions of the external blocks of channel split systems should be provided for smooth adjustment of the fan rotation speed, starting with very small, and heating the compressor crankcase (oil in the frost is hardening, so before launching, to avoid breakdowns, it must be heated). It is vital for the "winter" tubing and the defrost system, which allows you to pull the ice coat at the external block and maintain a working capacity at low temperatures.Even with a surface inspection of internal blocks of different manufacturers, constructive differences are detected, which allows you to enter the classification of this equipment. Most often on sale, you can meet the horizontal installation models (for example, horizontal blocks of the SKY series from Daikin (Japan), GTW from Airwell (France) and many other manufacturers), which are mounted behind the stiletto ceiling, hang on the heels or fasten the overlap plate bolts. Models of the vertical installation (for example, vertical modifications of FB-4A from Carrier) are fixed to the bearing wall on anchor bolts (as an option - on brackets or floor legs) and are closed with a decorative partition or rash. A variety of powerful vertical installation blocks - cabinet internal blocks (releases, for example, CED-V / CN-V Clevet-models) used mainly in large cottages. They can be put and open, on the floor, or hang using brackets on the wall in the storage room, a dark room or other auxiliary room. By the method of air intake, the internal blocks of the horizontal and vertical installation are divided into models with an end fence (the air is absorbed from behind, such as, for example, in EBS and EMD from Electra, Israel) and with side fence (air enters through the side hole, such as in CEI / CNI from Clivet). There are also universal blocks in which the air intake is possible either from the end, or on the side. Such is, in particular, the SPW-U model from Sanyo (Japan). Internal blocks with side air intake holes that are closed with embedded flush with a tail ceiling with decorative plastic air intake panels are often referred to as the blocks of a semi-width (embedded) type. The internal block, regardless of whether it will work only on recycling or will still be supplied to fresh air, the standard set of devices required for processing and moving the air flow. With the traditional layout at the inlet, an air filter from a polyester fiber or metal mesh is mounted, which carries out the "coarse" air purification and protects the equipment of the inner unit from the ingress of sera, insects and other particles capable of damaging the equipment or reduce its effectiveness. Next, the air flow passes through a heat exchanger, which is a frequency located parallel to the air flow of thin (less than 1 mm) of aluminum plates, tightly planned for a copper coil
Aluminum plate contacts can be very cold when the air conditioner works on cooling and inside the copper coil is evaporates prepared by the exterior refrigerant unit, or, on the contrary, hot, if the air conditioner operates in the heat pump mode, - at the same time, freon condensation occurs inside the coating, accompanied by intensive highlighting heat into the environment. To collect moisture condensing and flowing with aluminum heat exchanger plates during cooling air, a plastic or metal pallet is provided in the inner block. Water from it is removed by a gravity or using a built-in drainage pump that allows you to raise the drainage nozzle to 750mm from the bottom part of the device (for example, LG and Sanyo). From the heat exchanger, the air falls on the impeller of the fan (1 or 2, sometimes 4), located directly to the shaft of a single or three-phase motor or connected to the shaft using the pulleys and the drive belt. The air fan is injected into the insulated inside the polyurethane foam or mineral wool camshape chamber (comes separately) and further- into the network of air ducts. The control board is installed next to the inner block, in a separate case, but can be located inside the housing, in specially a shedding compartment.
Similar or even more complex "winter sets" are often mounted by manufacturers on models supplied to countries with a cold climate. Adapted to the frosts "Tanners" with outdoor blocks equipped with axial fans from Haier (China) operate to -18c. Delonghi (Italy) offers equipment that maintains efficiency up -25c. CARRIER AKOMPAITION (USA) - so also released channel split systems with external blocks 38 YCC, which are capable of functioning at temperatures on the street to -34.4c. However, in a lard frost, on the verge of minimum operating temperature, the efficiency of the refrigeration machine drops approximately 2-3 times, the equipment works for wear, quickly (the year of operation in the cold - against three, and more than a normal operation) reduces the compressor resource . To year-round, use the channel air conditioner with an external unit equipped with an axial fan, for indoor areas with a cold climate, one must be seriously rebooted in power (at least 2-3 times) and be prepared for premature capital repairs. Blocks with axial fans are mounted on the street - on the wall, on the open balcony, on the roof, etc. Air fence is carried out on the back side or around the perimeter of the block (having a barrel form, such as Carrier), emissions horizontally or vertically . Since the axial fans create a very small pressure, the air intake paths into the outer block and the air yield should be free, the outer block must be "breathing", and the likelihood of air from entering the input should be excluded. During operation, the block discounts heat into the environment, so you should not hang it under a neighbor. Sometimes the insides of the device need maintenance, so do not put it on a sheer wall to get to him only an industrial climber could. With the sensitivity of the neighbors to the noise, it is better to purchase a channel air conditioner, the external block of which at night reduces the speed of the axial fan and can work quieter than during the day (Daikin, Panasonic).
In large apartments and cottages sometimes use channel split systems, the external blocks of which are equipped with centrifugal fans. Such equipment offers Airwell (Series S), Clivet and a number of others. Blocks with centrifugal fans put on the vibration plants in the utility rooms (attics, basements, storage rooms, technical floors). The air for cooling the capacitor enters the block along the duct from the street or directly from the room in which it is set (heated), and is ejected to the street through the air ducts, the total length of which usually does not exceed 15-20 m and is determined by the centrifugal fan pressure (standard configuration It is 200-250 Pa). The use of blocks with centrifugal fans allows it sometimes easier to achieve year-round operation of the system at very low outdoor temperatures.
A very rare chance of acquiring a channel air conditioner with an external (compressor-condenser) unit with water-cooled condenser. This kind of split system is produced, for example, Mitsui (Japan), Clivet (model range of MCN) and others. The advantages of such blocks are simplicity, compactness and less than that of air-cooled devices, cost (by 30-50% ). Such internal blocks of split-systems will be able to warm the air indoors, regardless of how low the air temperature on the street lowered. But for their application, it is necessary to use flow water from the water pipeline, and the permission is required for it.
Control and control again!
As in the case of any other enough complex climate technique, the performance of the channel air conditioner depends largely on the reliability and degree of perfection of the automation system. The elements of this system are present in both the external and internal air conditioner block. However, its owner will have to contact only with the control panel.
Unlike splits with wall internal blocks, channel air conditioners, as a rule, have a wired control panel. It is fixed on the wall, at an altitude of 1.5-2 m from the floor, directly in the premises serviced. If the air-conditioned rooms are several, the remote control is mounted in that which is selected as a reference. The buttons on the console set the operating mode of the air conditioner - cooling or heating, the room temperature and the fan speed (1, 3, sometimes 8, like the "tubing" from Daikin). Some models of the panels are "taught" automatically select the necessary operation mode ("automatic operation"). In this case, the air conditioning control system analyzes the temperature in the room (temperature sensors can be located on the inner block or in the control panel, such as Panasonic) and a user specified, and then selects the mode, cooling or heating the air supplied and choosing the fan speed.
A large selection of additional modules is significantly expanding the capabilities of basic equipment. Thus, in the Senior series from Delonghi and UTNB from Rhoss (Italy), not only embedded water heat exchangers and electric heaters are supplied, but also, for example, humidification sections that allow to moisten the air along the signal from the humidity sensor installed in the room. Udelonghi has a section of an electrostatic filter that allows you to carry out more subtle cleaning and ionizing the air indoors.
As a rule, the console has a 24-hour or weekly timer, which allows you to set the air conditioning on and off time. In all models of channel air conditioners presented in the market, AUTO RESTART feature is provided. It resumes the operation of the device in the same mode after the short-term power outage. As a rule, the console saves settings in its memory for several (48) hours. On channel air conditioners with self-diagnostic function (Daikin, Hitachi, etc.), you can read information about the state of individual elements of the climate installation. You can get the necessary information not only on the liquid-crystal display of the control panel, but also on the remote computer monitor.
Channel split systems with supply ventilation can have both a single automation system serving at once all the installation and separate automation systems that allow you to control the inner block and a separate air heater. Naturally, using a single automation system is much more convenient than to work with different consoles, however, a similar solution for reasonable money (such as Clivet) can offer not every manufacturer of climatic equipment.
For an additional fee, automation is possible to significantly expand. You can use remote controls on IR rays. Developing GSM devices from Delonghi You will be able to control the channel air conditioning not only from the sofa, but also from anywhere in the world through a mobile phone.
| In conclusion, we note that the problem of individual temperature control in different rooms is solved with one "tubular". To do this, the channel split system must retrieve the zone control system. Such equipment is offered by Carrier, Trane (USA), LG declares similar automation (the cost of the required equipment is $ 1,000 to $ 1500 per room). The zonal control system supplies heated or cooled air to the room in the quantities needed to achieve the desired temperature. This operation is implemented using a microprocessor control unit and an electrical zone control valves that change the passage cross-section of the supply air ducts ranging from 0 to 100%. The electroclapanes themselves are installed in the ventilation channels directly in front of the diffusers. | Trademark | Country | Model row (series) | Number of models | Cold, kw | Heat, kW (with heat pump) | Height inside. block, mm. | Static pressure |
