Description

The invention relates to a device for introducing air into a room and / or for removing air from a room, comprising a housing that has an air inlet and outlet and in the interior of which there is a device for changing the air direction.

State of the art

Devices of this type, designed to direct air in air conditioning units, are known in the market in numerous forms and embodiments. For example, German Utility Model N7322128 describes a soundproof air gateway for residential or similar premises, consisting of a housing similar to a channel with inlet and outlet openings for the passage of air flow, which is made in accordance with the production conditions. In the interior of the air lock, the air changes direction and passes by the insulating layers, which are used for sound insulation.

DE 4232 315 A1 describes a device of the type indicated above, in which the device for introducing air consists of a body in the form of a rectangular parallelepiped intended for installation on the outer walls of buildings and / or apartments. In the housing there is a channel for changing the direction of air, having a section in approximately S-shape, which is lined with sound and heat-insulating material and through which air can enter the apartment from the outside.

Object of the invention

The basis of the invention is to create a device that has a very high coefficient of sound insulation and can be easily manufactured. In addition, the device should have significantly better stability and be suitable for installation in lightweight walls.

The solution of the problem

This problem is solved in that the housing consists of two shells, between which is located a device for changing the direction of the air, having the shape of a plate.

The advantage of making a casing of two shells is that its interior can be lined with soundproof layers. A device for changing the direction of the air can be manufactured separately and only then can it be connected to both shells. As a result of this, the shells can be disconnected from each other, so that the vibrations acting on one shell do not affect the other. In addition, the device for changing direction can be connected to the shells in such a way that it significantly improves the stability of the entire housing.

This is achieved primarily by the fact that flanges are bent from the shells, which during assembly can abut one another on the plane. Then the flanges can be separated from each other by inserting appropriate insulation strips.

However, first of all, it is provided that between the peripheral flanges a device is fixed for changing the direction of the air in the form of a plate, so that this device counteracts the twisting of the shells. It significantly increases the stability of the entire body, i.e. the housing always retains its desired shape.

Depending on the volume of air supplied, it may be advisable that the device for changing direction is surrounded by air from only one side. If you need to supply a larger volume of air, then you can position the device to change direction in the interior of the housing so that it flows around the air from two or even three sides.

The device for changing the direction of the air, having the shape of a plate, preferably consists of two panels, between which, at least partially, the insulation is located. This insulation may consist of a heavy sheet. A heavy sheet is a sheet with a high density, for example 3 kg per square meter.

The device for changing the direction of the air must be at least partially clad with insulation. It is easiest to use a layer of melanin resin, but other soundproofing materials are acceptable.

Care must be taken to ensure that the plate-shaped device for changing the direction of the air in the area that is visible through the air inlet or outlet is not clad with insulation, but is painted in the same color as the air inlet or outlet, for example white color. Currently, architects want smooth white surfaces to be visible in the interior of the air lock. Using the device for changing the direction of the air according to the invention, the best possible optical barrier is carried out. Through visibility or penetration of light from the corridor into the premises and vice versa is prevented.

The interior of the housing should also be lined with insulation, preferably in the form of a layer of melanin resin.

In a preferred embodiment, a low frequency absorber is provided at the bottom of the interior. It can also consist of a layer of melanin resin, but with a greater thickness.

In a preferred embodiment, the two shells are identical so that the air inlet and outlet are the same and are located at the same height. This reduces the cost of manufacturing the device.

Improving sound insulation contributes to the fact that the walls of the shells have different thicknesses. In this case, the shells are subjected to different vibrations and the transfer of vibrations from one shell to another is excluded.

Description of drawings

Further advantages and features of the invention are disclosed in the following description of preferred embodiments thereof, accompanied by drawings, where

figure 1 depicts a top view of a device for introducing air into the room and / or air output from the premises according to the invention;

figure 2 is a longitudinal section of the device shown in figure 1, in the working position and in a slightly modified form;

figure 3 is a longitudinal section of a further embodiment of a device for introducing air into the room and / or air outlet from the room according to the invention.

According to figure 1, the device for introducing air into the room and / or air outlet from the room contains a housing 1 having a slotted outlet 2 for air and an air inlet, shown only in dashed lines. The embodiments according to FIGS. 1 and 2 are characterized in that in FIG. 1, the air inlet 3 is formed by an inlet pipe, and the air inlet 3.1 in FIG. 2 is identical to the slotted air outlet 2.

As shown in figure 2, the housing 1 consists of two shells 4.1 and 4.2, which together limit the inner space 5. In the inner space 5 is installed a device 6 for changing the direction of the air, having the shape of a plate. This device 6 consists of two panels 7.1 and 7.2, between which a heavy sheet 8 and insulating strips are inserted 9. Parts of the panels 7.1 and 7.2 located in the inner space 5 are lined with externally layers of melanin resin 10.1 and 10.2.

The interior space 5 of the housing 1 is also lined on the sides with layers 11.1 and 11.2 of melanin resin, and at the bottom there is a low-frequency absorber 12, preferably also a strip of melanin resin, but much thicker.

In the embodiment according to figure 2, the shells 4.1 and 4.2 are made identical. Figure 1 shows that on the side of the shell 4.1, as well as the shell 4.2, the peripheral flanges 13.1-13.4 are bent. Through these flanges 13.1-13.4, the sheath 4.1 is connected to the same flanges of the sheath 4.2, and the flanges, if there is no device 6 for changing direction, are adjacent to each other through the insulating strips 14 separating them. The flanges can be connected to each other by any mounting means 15, e.g. screws, rivets, etc. The fastening means 15 are supported on the surface of the flanges, for example, via a sponge rubber seal or other elastic gaskets.

The device according to the invention operates as follows.

The device according to the invention is manufactured in a simple way by cutting the shells 4.1 and 4.2 and bending their edges with the formation of flanges 13.1-13.4. Since the shells are still open after manufacture, they can be immediately lined with layers 11.1 and 11.2 of melanin resin.

Similarly, a device 6 for changing the direction in which a heavy sheet 8 and the corresponding insulating strips 9 are inserted between two panels 7.1 and 7.2 is separately manufactured.

When connecting the shells 4.1 and 4.2 in the inner space 5, a low-frequency absorber 12 is placed at the bottom and then a device 6 is inserted to change the direction between the flanges 13.1, 13.2 and 13.3 and connected to them with fastening means 15. As a result, the housing 1 acquires a very high rigidity, so that the form of the device is provided, which remains unchanged in any case, which is desirable from the point of view of installation.

Further, both shells 4.1 and 4.2 are disconnected from each other by inserting insulating strips 14 between the flanges, so that one shell 4.1 can oscillate without affecting the other shell 4.2, and vice versa.

The plate-shaped device 6 for changing direction in a region that is visible through an outlet 2 or an air inlet 3.1 is preferably not coated with a layer of melanin resin, and this panel area 7.1 or 7.2 can be painted in the same color as the outlet or inlet for air. Thanks to this, the observer sees a smooth, barely noticeable surface, especially if the shells 4.1 and 4.2 and the part of the device 6 for changing direction located in the visible zone are painted white.

The device according to the invention should find application primarily in the walls of lightweight structures with high acoustic requirements. Figure 2 shows that the housing 1 is placed in the wall of a lightweight structure consisting of internal and external drywall casing 16.1 and 16.2. The housing 1 is held relative to the drywall sheathing 16.1 and 16.2 by insulating strips 17 and therefore it is separated from the wall of a lightweight structure. The same is true for output 2 and input 3.1 for air, and here the insulating strips are not shown in detail.

For reasons related to optics, output 2 and air inlet 3.1 are surrounded by frames 18.1 and 18.2, respectively.

The air that flows through the air inlet 3.1 into the interior 5 is rotated by the device 6 to change direction and is drowned out by layers 10.2 and 11.2 of melanin resin. The low-frequency absorber 12 provides sound insulation at low frequencies.

Further sound insulation during the passage of air towards the exit 2 is carried out using layers 10.1 and 11.1 of melanin resin.

The device according to the invention is particularly suitable for installation in walls of lightweight structures with particularly high requirements for building soundproofing degree R'b, from 32 to 50 dB for single-layer partition walls and 58 dB for two-layer partition walls, according to DIN 4109. It should be noted that Despite excellent sound insulation, only small pressure losses occur.

Additionally, the device can be equipped with appropriate fire fighting equipment (F90 optional).

An embodiment of the device for introducing air into the room and / or air outlet from the room, shown in figure 3, in principle, is a double version of the implementation of figure 2. Approximately in the middle, a round or slit-like air inlet 3.2 for air and a round or slit-like air outlet 2.1 is provided in the housing. The housing is also formed by two shells 4.3 and 4.4 surrounding the internal space 5.1, in which a device 6.1 for changing the direction of air, having the shape of a plate, is installed. This device 6.1 also separates the air inlet 3.2 and the air outlet 2.1 and is held by the side flanges 13.1 and 13.3, which are visible in figure 1.

Mineral wool with non-woven material is embedded as a 12.1 low-frequency absorber.

The advantage of this bypass sound insulator is that it can transmit a much larger volumetric flow at low pressure losses. The volumetric flow is approximately twice as large as in the device according to figures 1 and 2.
