This newly developed supply and exhaust air unit has the following
Improvements on:

The one that occurs with conventional air inlets

Blackening of the ceiling is prevented.

The air vortices required for evenly flushing the tree are created by the grid shape
stimulated.

j The compact design of the unit enables]

space-saving, cost-effective installation in new buildings ■

as well as in old apartments.

With the well-known heating and air conditioning systems, the supply air inlets and the exhaust air outlets independently of each other
installed in the rooms.

The new development is that now the air supply system
be built as one unit together with the exhaust system.
Both systems consist of the diffuser, the sound absorber
and the grille. More details are from the drawing
1 can be seen. The exhaust air is extracted via the supply air.

The grille has curved slats (wing profile). j The curvature requires that the blades are not excited by the air turbulence \ in audible frequencies. In the supply air area
are the slats curved downwards · This has the consequence that

the downward rotating air vortex is preferably excited. ..

This air vortex ensures even purging %

of the tree with supply air. The room temperature is therefore, with |

small deviations, constant. In the exhaust air area, I

the slats are curved upwards so that they can see into the |

Since the exhaust air is sucked in via the supply air and through the Lattice shape, which accelerates the supply air downwards, remains the blackening of the ceiling "" 6. Moses arises only through the hot_, Supply air bouncing against the ceiling, which is kept away from it with this construction.

For reasons of noise nuisance, sound absorbers were installed in both the supply air supply and the exhaust air discharge built-in. The noises from the air conditioning unit and those coming from the rooms are kept to a minimum degraded.

Supply and exhaust air unit for air conditioning systems Applicant: Claus-Peter Höptner Wolfgang Höptner 7336 TJhingen, Alte Holzhäuser Str. 1 Protection claims: 1) The supply and exhaust air unit in air conditioning systems is thereby characterized in that the exhaust air is discharged via the supply air supply through a built-in unit. These is structured as follows: The diffuser has the shape of a 90-arch with different cross-sections. Bottom, lid and side walls, which are provided with riveted edges at the joints are riveted to one another. The intermediate bulkhead is installed airtight in the middle between the base and cover with the help of lap joints. In the supply air area guide vanes are introduced. These have the shape of wedge-shaped sheet metal arches »They are also attached using lap joints. The edges of the guide vanes are staggered on the inlet side to ensure a uniform flow through the sound absorber to guarantee. On the absorber side, the guide vanes have a width so that the guide and attenuation profiles of the sound absorber inserted appropriately can be », The distances between the guide vanes are the same. The guide vanes and the intermediate bulkhead protrude 1 cm over the flange edge into the sound absorber The sound absorber consists of the damping part and the transition piece. The damping part consists of a metal jacket with inwardly kneaded flange edges. It is lined with sound-absorbing material. A groove is recessed in the lining on the side walls. Into this groove 7508640 08/21/75 Intermediate bulkhead consisting of a sound-insulating panel inserted. In the supply air area, cuboid guide and damping profiles are built into the Guide vanes on one side and completed by the profile lugs of the transition piece on the other side will. In the drainage area, the guide and damping profiles together with the profile lugs of the transition piece the shape of a symmetrical airfoil. The guiding and damping pro files exist e> also made of soundproofing material. This sound-absorbing material is glued with a heat-resistant adhesive. The transition piece closes the sound absorber to the grille down. It consists of a conical frame made of folded sheets. The frame has on the sound absorber side a flange edge. Two sealing plates are installed in the middle and parallel to the intermediate bulkhead. The upper one is flat, the lower one is kinked * The profile noses are provided with slots so that they can be pushed onto the bulkhead plates. The entire transition piece is held together by lap joints. The partition plates are inserted into the connecting U-profile of the grille. Transition piece, damping part and diffuser are pushed together and riveted. (Drawing 2). 2) The grille is characterized by its in the supply air area slats curved downwards and upwards in the exhaust air area * The slats Inben a wing-like one Profiles At the ends they are notched in such a way that they are lapped in the lattice frame can be attached. The lattice frame consists of angle profiles that are sawn and welded. Slots for the slats and the connecting U-profile are punched in the side parts of the frame. This U-profile is installed in the middle of the grille, the lower leg is bent upwards at an angle and it together with the Schottblecho "the connection between Grid and sound absorber.
