The invention relates to a device for introducing air into the room and/or for output of air from the room containing housing which has an inlet and outlet connections for the air and in the inner space of which is a device for changing the direction of the air.
The level of technology
Devices of this type, intended for the direction of the air for air-conditioning, well-known on the market in numerous forms and variations of execution. For example, in German utility model N 7322128 described sound airlock for residential or similar premises, consisting of a body, similar to the channel with an inlet and outlet for passing air stream, which is made in accordance with the production conditions. In the inner space of the air gateway of the air changes direction and passes by insulating layers, which are used for sound insulation.
In DE 4232315 A1 describes a device of the type specified above in which the device for introducing air consists of a housing in the form of a rectangular parallelepiped, intended for installation on outer walls of buildings and/or dwelling units. In case there is a channel to change the direction of air having a cross section approximately S-shaped, which is lined with sound - insulating material is ohms and through which the air can enter from the outside into the apartment.
The objective of the invention
The basis of the invention is to create a device of the type specified above, which is at low pressure loss has excellent sound quality and are particularly suitable for installation in the walls of lightweight construction.
The solution of the problem
This task is solved in that the device for introducing air into the room and/or output air from the room containing the body made with the possibility of embedding in the wall between the casings and having a front wall, a back wall and a peripheral side wall bounding an internal space of the shell, an inlet pipe for air, attached to the rear wall of the housing, an outlet for air, attached to the front wall of the housing, and a device for changing the direction of air in the internal space of the shell, which according to the invention made in the form of passing approximately vertically dividing wall located between the inlet the inlet and the outlet and dividing the inner space of the housing into two chambers, separated by-pass hole.
Inlet and outlet connections for air can be located approximately at the same height and be located in the intermediate overlap.
The inner space of the building is or may be at least partially coated with an insulating layer, in particular, a melanin resin.
A device of this type can be installed in a wall of lightweight construction is very different thicknesses. This device is intended primarily for conveying air from one room to another. Therefore, the inlet and outlet connections for air are preferably in the area of the intermediate floor. This means that air from the inlet pipe enters on the opposite side of the insulating layer is deflected down, then rises again and again deflected towards the outlet.
With the ability to change the length of the device in combination with the presence-chamber of the valve can be obtained insulating properties that match your specific requirements. No matter what size and length is the device, it can be in any case built into the wall of lightweight construction and is therefore very well hidden.
Form the inlet and outlet pipes for air is of secondary importance.
The whole device takes up very little space, but provides excellent insulation, at a very low pressure losses. This is a great advantage of the device according to the invention.
