The invention relates to the ventilation of the premises, in particular to supply natural ventilation devices.
In modern buildings that have glass panes, a shortage of fresh air. To eliminate the deficit needs aeration through the vents, transom or window sash, which is not always possible or desirable. The alternative is to use an additional supply devices.
Well-known and widely used fresh window vent valves, for example the Air-box, Unit-air and so on [see addresses on the Internet: http://www.air-box.ru., http://www.unit-air.ru.] These valves allow the so-called mikroprovetrivanie. However, they have a complex configuration and weak damping and does not provide filtration. In addition, in sub-zero temperatures on the street through the valves supplied, respectively, cold air.
Known Autonomous (not embedded in the frame) valves ventilation, mounted in the wall of the building. For example, the valve [RF patent for useful model 66488] represents the pipe, mounted in a through hole in the wall of the building. The ends of the tube closed by gratings, and in the inner channel has a silencer. The device has a simple design, but it does not stipulate filters and other devices, making the surrounding improving the quality of ventilation.
Known valve air infiltration KIV-125 [see address on the Internet: http://www.topclimat.ru/brands/kiv/tech6285.html], having in its composition a section of pipe, installed in a through hole in the building, in which is placed a layer of teplozvukoizolyacia. Outside the valve closed intake grille with mesh, on the other end, facing the inside of the premises, the valve filter is installed and the handle of the flow regulator. Valve KIV-125 simple in manufacture and operation. To install, just drill a hole in the wall in any convenient place. The disadvantage of valve is that it cannot be installed directly over a heating radiator for convective heat transfer to heat the incoming air from the street in sub-zero temperatures.
The problem to which the invention is directed, is to increase comfort.
Technical result achieved - ensuring the possibility of preheating the incoming air through the supply air flow in heating radiator.
The result is a modification of the structure.
The inventive device ventilation is composed of the air intake tube installed in the hole of the wall of the building and closed at the outer end of the intake grille. The device is equipped with an adjustable valve and the filter is m From the prototype device differs in that it is further provided with connected with the intake pipe duct mounted along the inner side walls of the building and located in the immediate vicinity of a heating radiator or at least partially heating radiator, wall additional duct is made of at least one vent window or perforation, directing airflow to the radiator, and an adjustable valve and filter are located in an air duct.
The device may further comprise a noise reduction. It is preferable to set the noise reduction in the secondary duct, namely, front adjustable damper and filter the air flow. Also preferred is a labyrinth form of the noise reduction.
In more detail the nature of the device disclosed in the example below, the implementation and illustrated in the drawing, which shows a longitudinal section of the device (schematically).
The device ventilation is the air intake tube (pipe section, for example, from a polymeric material) 1, which is installed in a through hole of the wall 2 near the heating radiator 3. Outside the pipe 1 is closed with the end of the intake grille 4, designed to protect against leaves, p is ha, insects. Grating 4 can be further provided with a grid. The pipe 1 is attached an additional duct 5 having, for example, the shape of a tube of rectangular cross-section and closed the lid from the end. Additional duct 5 is fixed on the inner surface of the wall 2, is oriented perpendicular to the pipe 1 and at least partially wound in the gap between the wall 2 and the heating radiator (heater) 3. Additional duct 5 may be either straight or bent at different angles, it may have a solid case or to be assembled from separate elements.
In the side wall of the duct 5 facing the heating radiator 3, made at least one vent window, or perforation 6. In the inner channel of the duct 5 posted by filter 7 that is designed to clean the air, and adjustable (swivel) flap 8, which is intended to regulate the amount of air flow. There, in the inner channel of the duct 5, for example, before (air flow) filter 7 and a valve 8, installed the absorber 9. He may have a labyrinth shape, similar to that used in automotive mufflers. The absorber 9 can be running.
The device ventilation operates as follows.
When open the valve 8 air from outside enters celestamine grating 4 in the channel of the pipe 1 and then to channel additional duct 5. Passing through the filter 7, the air is cleared of particles. When you exit vent window or through a perforation in the wall of the additional duct directs the airflow on heating radiator, or in the space behind it, where it is heated, and then goes in a ventilated room. By turning the valve 8 can adjust the intensity of the ventilation. The absorber 9 prevents the penetration of sound into the room.
Thus, the proposed device ventilation design is simple and can be easily installed in any room.
The device allows the heating coming from the outside air through convective heat transfer, because it can accommodate the output of the unit directly behind the radiator (or under it), including the already fixed on the wall.
