<p>The air distributor is used especially in industrial work rooms. Horizontal beams under the ceiling carry panels between which are arranged air distributing profiles. The latter have V cross section and openings for air, and the downwards flow of air is uniform. Circulation and mixing of air is prevented especially in upper air layers. The cover plates (2) are arranged in series with gaps forming ventilating slots (5). The V cross section profiles (3) are inverted and their free ends are turned outwards as flanges. These flanges are arranged under edges of the plates on the visible side. The V profiles have holes which pass through the apex part of the profile. These holes are uniformly spaced over profile length along profile axis of symmetry.</p> |
