By ordering the supply and exhaust ventilation system, we sometimes forget that after the end of work in the field of our view, only air distribution and air intake devices will be. Meaning ventilation grids, diffusers, nozzles, perforated panels and air distribution columns. Our judgment about the ventilation system largely depends on the choice of precisely these elements, which should be organically fit into the interiors of ventilated rooms.
The air distribution devices are installed on the mouth of the supplied air ducts, and the exhaust air intakes are installed. In addition to the aircraft laying scheme, these elements can be on the floor, on the ceiling or on the walls. The air distributors are fed into the room cleaned difts, and the air intakes are removed contaminated. In fact, the air distributor can be compared with a shower nozzle on the mixer, and the air intake device, with a funnel, through which water is merged from the bath. However, there are universal devices that are used both for feeding and to remove air. Skimny or plumbing equipment compared to compare them.
Skupoy will receive discomfort
Thus, air distribution and air intake devices must provide sufficient mobility (speed) of air indoors with their design and arrangement. The lack of air movement or excessively low speed is associated with poor ventilation. Cast conditions around a person formed a thin fixed air sheath, which is rapidly saturated with water vapor, acquires the body temperature and reduces the organism heat transfer. Easy movement of air blows up this enveloping man layer, superheated and saturated with water vapors. However, it is worth a little rearrangement, and air flows moving around the room with too high speeds (especially if the temperature of the ventilation air is below the human body temperature), will be perceived as a draft, because of which you can still catch.
The video lattice is selected so that air mitigation corresponds to human conditions comfortable. There are 0.15m / s dust rooms at a temperature of 23-24.
The selection of air distributors for the home is considered successful if zones are not formed in the ventilated rooms with too low or, on the contrary, too high temperatures, which would cause discomfort at the inhabitants. Stagnation areas should not appear, often encountered when carrying out the premises of a complex form, for example with large niches.
It is important that during the operation of the ventilation system, the air distributors did not violate acoustic comfort. After all, the noise arising from the passage of air through these devices is by no means so harmless, as it may seem at first glance. He suppresses the human nervous system, does not allow him to rest fully. The noise level generated by lattices or diffusers depends on the flow rate, from the size of these devices themselves, as well as on the characteristics of the room (volume, sound absorption of IT.P.). If possible, the lattice should prevent the penetration into the noise room from the air conditioner fan or the inner unit of the air conditioner (reflect back to the air duct). Note that some sensitive people are able to calmly fall asleep, only if the noise level from the supply and exhaust ventilation system does not exceed the 26ndB.
In addition, it is necessary that the terminal elements of the ventsystem are harmoniously fit into the interior. Some owners put this condition almost in the first place. Visual perceptions of visual perception are the form of air distribution and air intake devices, their size, color and surface texture.
It is desirable that the air distributors are miniature, they practically did not differ in color and surface texture from wall decoration and ceilings. For other premises, on the contrary, large designs will be suitable, playing the role of color beacons, contrasting with trim. To facilitate the search for air ducts suitable for the design of "crowns", we want to introduce you to the range of air distribution and air intake devices presented in the Russian market.
Tribute tradition
The most common terminal devices used in the supply and exhaust ventilation systems (as well as air conditioning and air heating) apartments and cottages, ventilation grilles are considered. They are used in residential and non-residential premises, in baths and saunas.Wall ventilation grilles. It is usually mounted on the walls, above the people's stay zone (more than 2m from the floor), in the places of gasket of ventilation channels. Often, such models are installed on stitched ceilings. Wall lattices, as a rule, consist of a frame that contains one or two rows of lamellas, or rigidly fixed, or rotary (to change the direction of the air flow). In models with two rows of lamellasties, the rear row is mounted perpendicular to the front.
Steel, non-ferrous metals, plastic, wood and even gypsum are used for the production of wall-mounted vents. Such lattices more often than other endworkers are supplied painted in different colors. For example, in the assortment of Twitoplast (Israel) there are plastic lattices Super Tech silver, steel, blue, pearl, red and other colors. Azavod "Arktos" (Russia) recently launched a new series of colored lattices, which, according to the manufacturer, fits perfectly into the interiors, decorated with marble, granite, malachite, wood of noble rocks. Painted in various colors of the lattice offers buyers and enterprise "Plant" Season "(Russia).
Rama lattices can be square, rectangular, round or elliptical, and also to have a star shape, IT.P. Most often, wall models are flat - they are installed on a flat surface. But sometimes there are concave and convex samples - for the "overhead" installation on the curved walls, the ducts of the circular section. Such, for example, rectangular RTS grilles from Metalpress (Israel).
Outdoor ventilation grilles. This is another representative of the Ventray Talk family. Such models are mounted flush with the finishing surface of the floor under the windows or near the walls of the room. Such devices are used mainly in cottages, in the systems of air ventilation systems. Metal or wooden lamellas, of which the floor grille consists, can be located both across and along its long side. Large sizes (1860cm and more) are usually free, without fixing, are inserted into the frames attached to the connecting chambers closed in the floor (chutes). Air is supplied through the nozzles to which the supply air ducts laid under the floor are connected. By type, such lattices are sometimes impossible to distinguish from embedded convectors from the floor; Some models of the latter, by the way, can also be used as an air distribution elements of the ventilation system due to the presence of a pipe for connecting the air duct on their gutter.
Pretty grilles. Where interior doors with a hermetic entrance are installed, to ensure the operation of the supply and exhaust ventilation, sometimes it is necessary to depict the room. For this, the holes are performed in the doors or walls and are supplied on both sides by the streams. Such models offer, for example, Halton (Finland). The TVA and TVB lattice produced by this manufacturer, designed for wall mounting, light-proof and reduce the noise level. TVC overproof grilles, also light-tight, are installed on the door with a thickness of up to 45mm.
On the line of inflow
Slit diffusers are used in supply-exhaust ventilation systems for feeding and to remove air from the room. Provide Bo / Weight than lattices, long-range jets. May have one or more long and narrow slots. Embed, as a rule, in the ceiling (less often wall or window sills) in the kitchens, in the halls of cottages, in private sports halls and other rooms.
Slit diffusers with connecting chambers. They are mounted in tail ceilings. It seems more to be more likely, but immediately several devices. The slots for the release (fence) of the air form an inextricable line-direct or zigzag, say, repeating the outlines of the room around the perimeter, with some indentation from the walls. Some air distributors can be used for tributary, others - to remove air, third and inactive, playing the role of decorative elements. We want to mention the diffusers of LD-14 from Impklima (Slovenia), the length of the slit from which from 500 to 2000 cm. Some manufacturers offer not only straightforward, but also curved (in the plane of the slit) model. This installation can be created on the ceiling wave-like lines or rings for the distribution (fence) air. These are SDML slotted diffusers from Metalpress. Produce curved models and in the enterprise "Closed systems" (Russia).
Air Plafones
These devices are used to supply a large amount of air with the help of jets diverging on the side, quickly mixing with the surrounding atmosphere, as well as to remove air. They are assembled, as a rule, in a stevy ceiling, however, it is often possible to mount directly on round flexible or rigid air ducts, on horizontal and inclined surfaces, falseland IT.P.
Disk plaffones. Sometimes they are called round diffusers. These devices are very suitable for premises such as toilets, kitchens, bathrooms, living rooms. There is a ring gap between the disk and the casing of the ceiling, through which the air enters the room or goes into the exhaust. To increase or decrease the amount of incoming or removed air, the size of this slit is adjusted, smoothly rotating the disk.
Disclamps made of steel, aluminum or plastic. Diameter of devices - 10; 12.5; fifteen; 16 and 20cm. Plastic models are not painted, standard color - white (RAL9010). Auto aluminum or steel models Some manufacturers at the request of the customer are painted in the tone of the decoration of the room or in any other colors. DEC (Netherlands) vasserize (Netherlands) can be distinguished DVS-P disk air distribution plaffers from steel rolled products with smooth air flow regulation.
Multi-diffusion plafones. Such devices are installed on the ceilings in large rooms (in the halls of cottages, halls for receiving guests), sometimes mounted in the kitchens. They consist of several cones with increasing diameters and can silently submit significant volumes of fresh air into the premises. Used in exhaust systems.
You can also find round, square and rectangular multi-profusion plaffones from metal or plastic of a wide variety of colors and sizes, with air flow control and without. Among the models without adjusting the air flow, it is worth noting the dial diffuser of the square form DFA (HALTON), designed for mounting in the suspended ceiling. The device is attached (depending on the size) to the air duct with a diameter of 12.5; sixteen; 25 or 40cm.
Supply plaffers with a flux of flux. These models are designed for the largest premises of private pools, sports halls. Mounted similar devices in the tail ceiling.
The intake plaffones with a flux of the flow are imparted to the room through the blades that are installed motionlessly or rotate the stream. Moreover, the slope of the blades to the flow can be both adjustable and unregulated. Plafones with a flip of flux are usually installed in low rooms (2.6-4m). Thanks to the twist, the air leaving the speed quickly loses speed and mixes the room with air. Make such devices mainly from the metal, less often - from plastic. Form - round or square.
Types of air jets
The form of a air jet depends on the form of the airway the air distributor. Round or rectangular air dust openings create a compact air jet of conical shape. So that the jet is flat, the ratio of its thickness to the width should be 1:20. Air jets that occur when passing through ring-shaped or rectangular slot holes in the ceiling or walls are called fan.
Silent handling
To create several multidirectional jets, multi-minded devices are used. They are used in rooms with a significant amount of fueling devices. They can find use, for example, in a room, oversaturated with audio equipment and computer equipment.Cassette nozzles. In addition to the external attractiveness of this kind of device, they have good performance characteristics. Most often, they are mounted in tailc ceilings or falseland. Form instrument and rectangular, square or round. On the air distribution panel reversed, nozzles are located, each of which can rotate around its axis. They are easy to install at any angle to direct the air jet in the right direction. In addition, the noise level of these devices is minimal. Thanks to the properties of the equipment, it is possible to implement thousands of options for air distribution, without changing the level of noise and air volume. Among the technicians presented in Russia, it is worth noting the cassette nozzles from Swegon and Systemair companies (Sweden).
Swelto, yes not that!
Small air supply speeds provide perforated air distributors and air intake devices. They also allow you to create separate well-ventilated zones in the room, for example above the dining table, over a bar counter, in the garage, in the workshop (above the workshop IT.P.).
Perforated air distributors and air intake panels. Produced mainly from steel rolled aluminum. There are these devices directly above the zone selected for intensive ventilating so that it is "flooded" significant amounts of supply air without its active mixing with the surrounding air. Swinteriere looks effectively square panels with perforation for the ceiling type "Armstrong" with 6060cm cells (for example, THB from Halton, TSO from SystemAir). Firm "Lotonservis" (Russia) produces perforated air distributors, on which two-three-minute metering holes of the perforation of different shapes (circle, oval, star IT, can be performed according to the customer's sketch. These holes can form point inscriptions or drawings on the air distributor.
Column that breathes
An elegant addition of the interior of a large hall, a home theater, a cabinet or any other room that requires a significant inflow of fresh air, is capable of becoming an air distribution column.Low-speed air distribution columns. Such devices are used in systems operating on the principle of Displacement Ventilation (Ventilation by displacement). It is based on the use of natural convective flows rising from heat sources (including from people). Due to low-speed distributors, pure trim air enters the room at a speed of 0.2 m / s. It displaces heated polluted air to the ceiling, from where it is removed by the exhaust channel system (for example, through ceiling plaffones).
Among the low-speed air distribution columns presented on the market, it is not difficult to find models, the appearance of which is optimally combined with the interior of your room. Standard columns high up to 1.5m in a horizontal section are a rectangle, a circle, semicircle or sector. But it is possible to order a product of any form, with a different pattern and type of perforation, painted in any color, equipped with decorative upper and lower lid from aluminum, wood, stone IDR. The air distribution columns are mounted on the floor, on the wall, in the corner, embedded in the wall or to the floor. The air duct of supplying fresh ventilation air is paired to them for falsely or in the floor-plated channel.
True, the choice of the location of the columns must be clearly coordinated with the design of the ventilation system by the company still at the stage of the draft project. It takes into account the whole range of factors, such as the location of heat sources, the presence of walls under the right angle to the flow direction, IT.P.
From the equipment presented in the market, such as low-speed air distribution columns of the LGP series (rectangular, with trilateral distribution), LGC (rectangular, with one-sided distribution), LGV (semicircular angular) and LGD (semicircular end) from Systemair. They will perfectly fit into the most exquisite interior.
Where can one buy
The production of air intake and air distribution devices for systems of supply and exhaust ventilation, air conditioning and air heating of premises today are engaged in hundreds of foreign and dozens of Russian companies. Preference when choosing equipment is better to give the products of a large firm manufacturing equipment based on serious research and development work. Among the largest foreign companies specializing in the release of air distribution and air intake equipment, I would like to mention the already mentioned company TROX, HALTON, SYSTEMAIR, SVEGON, IMP Klima, Metalpress and a number of others. The lines of Russian manufacturers of lattices, plafones and other types of air distributors are called the company "Arctos" and "Season" plant, which pay special attention to the design of their products.
Lattices and plaffones cost from 100-200 to 1000 rubles. Puzzle, nozzles with nozzles are at least twice as expensive. The cost of some import models of air distribution columns may exceed 25-30 thousand rubles.
If you are going to order air distributors painted in a unique color, you will have to pay extra for it. Color selection, for example, for two ventilation grids can increase their cost several times, and it is not a fact that the manufacturer will take over the execution of this order, it is more expensive to mess with a minimal party. Now, the set of vents for the cottage with an area of 500-700m2 in some cases will cost only 10-20% more expensive set of standard execution.
In the preparation of the article, the materials of the company "Euroclimate" were used. The editorial board thanks the company "Inmut", "Arctic", Systemair for the provided photographic materials, Trox, Swegon, Phantom Climate, "Season" plant for helping when organizing equipment shooting.
