Description

117727

The present invention relates to a supply air beam consisting of an elongated housing with a supply air duct attached at one end.

5 For large room ventilation, there are a number of perforated ducts and supply air ducts with directional nozzles (eg plastic nozzles) for ceiling installation. Supply air ducts allow the supply air to be distributed evenly over a wide area, for example in a factory hall.

The problem with the hole duct is that after the installation it is not possible to change the direction of the supply air 10. The conditions in the factory hall (read the heat loads) change when the mills make production arrangements. The supply air should also be redirected.

The supply air can be well directed through the supply air duct with plastic nozzles. However, the problem with this solution is that the plastic nozzles limit the amount of supply air 15 when the cross-sectional area of the duct is determined. This is, of course, due to the small amount of supply air flowing through the nozzle in relation to the surface area required by the nozzle, '

OBJECTIVE OF THE INVENTION It is an object of the invention to eliminate the said disadvantages. The supply air beam according to the invention is characterized by the fact that the sides of the housing are partially perforated for a high flow of air 20 and that there are control nozzles in the perforated areas which control the supply air currents in the desired direction. / or below. i • * * · * f

The supply air beam according to the invention, which combines at its sides a large surface area of the duct (high supply air flow) and a good possibility for the control nozzles to direct the fire: * · 25 air flows.

The large amount of supply air flowing through the perforated area can be controlled in a desired direction, e.g. up and / or down, by means of a smaller supply air flow through the nozzles. There are other options to direct the supply air flow by taking * * *, *. take into account the heat load and / or cooling needs of the factory hall.

Various embodiments of the invention are set forth in the dependent claims.

The invention will now be described, by way of example, with reference to the accompanying drawing, in which Fig. 1 is an axonometric and partially sectional view of the supply air beam, Fig. 2 is a side elevation view of the supply air beam, and

The supply air beam consists of an elongated housing 1, at one end of which a supply air duct can be attached. The sides of the housing are partially perforated 3 and there are guide nozzles 4 above and below the bore regions for controlling the supply air flows in the desired direction. In this example case, upward, as indicated by the gray 10 arrows. Inside the housing is an air equalization bag 5 which is as long as the interior of the housing 1. The housing 1 is trapezoidally shaped at its end, f such that the base is shorter than the upper edge. The guide nozzles 4 are made of plastic, so that they can be easily pressed into the holes made therefrom by the gripping tabs and turned in the desired direction.
