Abstract

FIELD: ventilation.

SUBSTANCE: organizing air flows in residential, commercial and other premises, namely, systems of secret-mounted ventilation equipped with air distribution devices, “invisibly” integrated into the external architectural ensemble and internal interior design. In particular, one of the solutions for integrating the ventilation system into the interior is the installation of a linear slot diffuser in the corner ceiling area along the perimeter of the room. The claimed technical result is achieved due to the linear air distribution unit, made of three asymmetric aluminum profiles and an air receiver with integrated inlet nozzles, interconnected by power lamellae, acting as jumpers to increase the overall rigidity of the structure, while the inner surface of the profiles from an aerodynamic point of view forms a working volume for supply air distribution to the premises, among other things, in the lower part of one of the profiles there is an orthogonal flat protrusion, which, after the final installation of the entire structure of the air distribution unit, forms a parallel plane with the wall. The resulting gap between the flat protrusion of the profile and the wall surface serves as a linear slot for the formation of a flat submerged jet of supply air.

FFECT: organization of the primary air inflow around the perimeter of the room with the help of linear-type corner air distribution units, which, in turn, are discreetly mounted in the ceiling, creating a continuous line, to achieve the best aesthetic effect, replacing such an interior element as a ceiling plinth.

Description

This technical solution relates to the field of equipment for ventilation and air conditioning systems of "secret installation", in particular to systems for supplying primary air around the perimeter of the room using linear diffuser-type air distributors mounted instead of a ceiling plinth.

Linear diffuser-type ventilation system is used for "invisible" installation into the ceiling along the perimeter of the room instead of the ceiling plinth to achieve the best aesthetic effect in the interior ensemble and provides a uniform supply of primary supply air.

From the prior art, technical solutions are known for low-speed air distribution units of the supply and exhaust ventilation system of "secret" installation, which are, as a rule, linear diffusers made in the form of a common frame with an air collector, which, apparently, performs the function of a receiver. Examples of such solutions are air distribution devices known from sources: RU 142080, EP 3406985 A1, KR 101377611 B1, US 3962960, US 5194042, US 20120052790 A1, RU 90882 U1, RU 2716291 C1, US 453734 7, US 7384168, ES 1064231 U, RU 2751963 C1, RU 142080 U1, RU 206706 U1, RU 207241 U1, RU 207353 U1.

As direct analogues, we can consider the designs of corner air distribution devices manufactured by the following companies: Expella (Australia) (https://expella.com.au/productyshadowline-wall-diffuser/); Holyoake (https://holyoake.com/).

The products of these companies represent technical solutions on the market, as a rule, made in the form of frame solutions with an air collector (receiver) or a static pressure chamber made of profile metal structures, devoid of specific aerodynamic dampers of the supply air and other devices for equalizing primary air flow in longitudinal sections . Supply air flows are often formed and directed using special edges forming a slotted nozzle of rectangular cross section, while in the longitudinal direction, when primary air is supplied through pipe ducts to a common air collector (receiver), the issue of constant air flow in the longitudinal section remains unresolved . Among other things, the principle of mounting the general structure to the vertical plane of the walls is not disclosed.

The main disadvantages of the known solutions include the designs of various air collectors (receiver) designed without taking into account the distribution of flow rates in the longitudinal section of the slotted nozzle, which leads to the presence of cocurrent jet flows and difficult design prediction of primary air streamlines.

Additional disadvantages include the lack of solutions in the field of condensate separation when operating in humid air, and the lack of design solutions and devices that facilitate installation and service work can also be attributed to the disadvantages.

The claimed invention is aimed at solving technical and aesthetic problems, in terms of the peripheral supply of fresh air around the perimeters of residential, commercial and other premises, eliminating the shortcomings of the solutions known from the prior art.

The technical result is to increase the comfort parameters in the premises of domestic, commercial and other use, due to the use of a specially designed air distribution unit, which involves a hidden aesthetically advantageous installation of the structure around the perimeter of the premises without a significant deterioration in the quality parameters of the supply air.

The claimed technical result is achieved through a linear air distribution system containing an air receiver with integrated pipes for fresh air, a linear diffuser that forms flat flooded jets of fresh air, formed by three different profiles, while the profiles are connected by power lamellas that act as jumpers to increase the overall rigidity of the structure , and the power lamellas are fixed in the grooves and ledges in the upper part of the two profiles. One of the profiles is made in the form of a corner and acts as a mounting element to the vertical plane of the walls of the entire air distribution unit, moreover, on one of the planes of which there are fastening protrusions for fixing other structural elements, while on the other plane there are equidistant holes. The second profile is also made in the form of a corner of an s-shaped design with a hidden recess that allows you to completely drown the heads of the screws into the body of the profile without additional machining and reciprocal mounting protrusions for attaching to the mounting profile in an interference fit, in the upper part of which there is a groove and a ledge for installing a power lamellas. The third profile is made in the form of an orthogonal one and has an end in the form of a flat protrusion in its lower part and, in turn, has a reciprocal groove and a ledge for installing a power lamella.

In a particular example, the air receiver is made with integrated air flow separation devices to implement a submerged jet without significant longitudinal velocity gradients.

In another particular example, in the lower part of one of the profiles, an ending is made in the form of an attachment point for a stretch PVC ceiling.

In another particular example, in the lower part of one of the profiles, an ending is made in the form of an attachment point for a fabric ceiling sheet.

In another particular example, in the lower part of one of the profiles, an ending is made in the form of a plaster unit of a standard form.

In another particular example, an air flow divider is attached to the power lamellas, which increases the rigidity of the overall structure.

In another particular example, a flat mesh air divider is attached to the load-bearing structures to reduce the degree of turbulence in the supply air.

In another particular example, an orthogonal angular profile that forms the flow path of a linear diffuser is made with moisture separation holes.

In another particular example, a light diode strip and an opal filter are attached to one of the profiles in order to implement peripheral illumination of the room.

The claimed invention is illustrated by figures 1-11.

In FIG. 1-2, the general design solution of a diffuser-type linear air distribution device (1) is shown, the claimed design of which contains two main air working volumes (A) and (B), and also has two characteristic sections of the flow part (C) and (D). Moreover, in the general case, the working volume (A) significantly exceeds the volume (B) in order to calm the supply air from the ventilation system. In turn, the cross section of the flow part (C) significantly exceeds the cross section (D), in order to form a narrowing outlet linear hole, the narrowing of the flow part is also due to the angle (α) in the lower part of the orthogonal profile (7).

The design of a diffuser-type linear air distribution device (1) contains the following main elements (Fig. 1-4, 8-11): an air receiver (2) with a working volume (A), a housing (3) and an inlet pipe (201), made from molded thin-walled sheet metal; metal support profile (4) of an angle type; an s-shaped profile (5), a power bridge-lamella (6), an orthogonal profile (7), and the cavity formed between the profile (7) and the conditionally shown wall surface (9) forms a flow part with a working volume (B). The characteristic dimension (C) is obtained as a result of the assembly of profiles (5) and (7) using a power jumper (6), the characteristic dimension (D), in turn, is actually obtained after the operation of mounting the general structure to the metal support profile (4), which pre-installed on the vertical surface of the wall (9). The orthogonal profile (7) has different versions of the ending for joining the air distribution unit with various standard solutions for ceiling coverings (8) (fabric ceiling cloth (802), PVC stretch ceiling (801), plaster unit of standard shape, etc.).

In FIG. 3 shows the principle of fixing the body (3) of the air receiver (2) to the profile of the angular orthogonal structure using clips (301) of the petal type, which are bent at a right angle after the operation of centering and fitting the body (3) itself to the profile (7).

A linear diffuser in the design of the air distribution device (1) is formed using two profiles connected by power lamellas (6) as frame jumpers, which in turn form an air flow path with a working volume (B) and characteristic dimensions in the inlet section (C) and exit section (D), and the size (C) in the general case significantly exceeds the size (D). The air flows are organized as follows (Fig. 4), the primary (supply) air enters from the duct network of the ventilation system through the nozzles (201) into the working volume (A) of the air receiver (2), and the configuration of the working volumes is selected in such a way as to achieve suppression of pulsations in the flow from the supply fan of the ventilation system and reduce the velocity head. Leaving the air receiver, the flow enters the working volume (B), the geometry of which is determined by the shape of the profile of the angular orthogonal structure (7) and the vertical mounting plane (9) (for example, the wall of the room), then enters the room in the form of a near-wall flat flooded jet formed in turn, the profile element (703) (7) and the wall plane (9) in the form of a linear hole with a characteristic dimension (D). Thus, the peripheral supply of supply air around the perimeter of the room is carried out.

Also in FIG. 6 shows the principle of connecting the support profile (4) with the s-shaped profile (5), by fitting the element (503) of the profile (5) into the hinge protrusion (402) of the profile (4) and then fixing the fixing lock (503) of the profile (5) in the reciprocal ledge (401) of the profile (4).
