Note: Company H. Krantz, 51 Aachen, Industriestr. o.no. Bez .: lectern for congress halls and similar meeting rooms

The invention relates to a lectern for congress halls and similar meeting rooms with a device built into the lectern for ventilation and air conditioning of the seat, with the supply air through blow holes in the listening zone of the listener. will lead.

In a known desk ventilation, air outlet nozzles are provided on a pressure box running longitudinally under the desk top connected that with a stretching over the leading edge

of the desk extending obliquely upward blowout opening related (BDGK 1 9 ^ 5 699). At this The well-known desk ventilation is located in a pressure chamber of the conditioned air under the podium by means of a desk cap serving line connected pressure box at the front end of the desk. The one that ends with the front edge of the desk The wall of the pressure box is provided with air passages that open into a vertical air outlet nozzle, due to the injector effect of room air from the lower opening of the Air outlet nozzle can be sucked in.

With the well-known desk ventilation, the air inlets open directly in the vertically arranged air outlet nozzle., and the air escaping from the pressure box collides with the End wall of the air outlet nozzle, which means that the injector effect cannot develop optimally. It is also included the mixing distance is quite small, so that a good and intimate mixing of climate and room air is only guaranteed to a limited extent.

The invention improves the known desk ventilation by that the pressure box is moved back away from the front end of the desk to its center and at the upper end of its front

wall outlet nozzles, one of which is arranged vertically Air intake port entrained room air and the supply air mixed from climate and room air in one under the desk along the mixing chamber to an air outlet that is bent upwards by about 80 ° at the front edge of the desk is guided into the breathing zone of the listener.

Due to the design according to the invention, the outlet nozzles of the pressure box blow the conditioned air and the room air entrained by the nozzle or nozzles into a relatively long mixing space with the guarantee of an intimate mixture, which is bent upwards by the diversion of the mixing space in the field of vision ' as the listener's blowing air outlet is improved.

According to a further embodiment of the invention, the air-conditioned air in the pressure chamber is under the podium of the congress hall connected via a supply line serving as a desk support Pressure box provided with a Sehalldämmplatte, which largely in the inflow cross-section of the air conditioning to the pressure box submits. The Sehalldämmplatte thereby acts at the same time as a throttle plate, which regulates the inflow of the climatic air throttles the pressure chamber under the podium in the pressure box

and thus the speed of the air flowing over from the outlet nozzle (s) into the mixing chamber is reduced so far, that the supply air blown out of the blow-out openings into the atraungsbereich of the listener is not perceived as a draft.

Around the air outlet nozzle from thrown into the outlet opening To be able to make objects free is, according to the further invention, below the in the breathing area of the A cleaning flap is provided for the handset leading deflection of the mixed air.

Finally, according to the invention, the upward in the Atraungsbereieh of the listener's curved air outlet pipe as a holder of a screen for one at the front end of the desk attached lamp serve.

In the drawing is an embodiment of a desk for congress halls and similar meeting rooms with an im Desk built-in device for ventilation and air conditioning of the seat in a vertical section schematically and the mixing point of climatic and indoor air is illustrated separately on a larger scale.

From a pressure room (not shown) under the podium can air-conditioned air via a distribution pipe 1 serving as a desk support in a roughly arranged in the center of the desk and flow across the desk extending pressure box 2. In the pressure box 2, a sound insulation panel J5 is arranged, which the inflow cross-section of the conditioned air from the distribution pipe 1 to the block box 2 largely blocked. On the front wall of the pressure box 2 are outlet nozzles 4 from a slot nozzle or several juxtaposed at its upper end Individual nozzles are provided that blow the air conditioning into a mixing space 5, which extends along the front part of the Table top 6 of the desk extends.

The front wall of the pressure box 2 is provided with a suction line 7 for room air, which merges at the upper end into the area of the outlet nozzle or nozzles 4 in the mixing room 5, so that the climatic air exiting through the outlet nozzles 4 sucks in room air that is in the under the desk top 6 longitudinally extending, relatively long mixing space is intimately mixed up to the exit from the upwardly bent blow-out opening 8 and blown out into the breathing area of the listener.

Below the upwardly bent air outlet 8 is a Cleaning flap 9 provided to the air outlet 8 from objects thrown into it, such as B. paper balls, Staples and the like to be able to free.

The rear wall of the air outlet 8 can be used to attach a screen 10 made of a translucent, glare-free material for a lamp or fluorescent tube 11 attached to the front end of the desk.
