Panel for a suspended heating and/or cooling ceiling

Abstract

A panel ( 10 ) for a suspended heating and/or cooling ceiling comprises a flat metal cassette having mutually spaced upper and lower metal sheets ( 11, 12 ) defining a sealed space ( 17 ) therebetween. The metal sheets are perforated by registering apertures ( 13, 14 ) which are sealed against the space along the circumference thereof. At least one of the metal sheets around each aperture forms an embossment ( 15 ) attached to the other metal sheet as a spacer between the metal sheets. An inlet ( 19 ) and an outlet ( 20 ) communicate with the space for circulating a fluid heat carrier through the space in heat exchanging relationship with the panel.

1 . A panel ( 10 ) for a suspended heating and/or cooling ceiling, defining a sealed space ( 17 ) with an inlet ( 19 ) and an outlet ( 20 ) communicating with said space for circulating a fluid heat carrier through the space in heat exchanging relationship with the panel ( 10 ), wherein the panel comprises a flat metal cassette having mutually spaced upper and lower metal sheets ( 11 ,  12 ) defining said space therebetween, and that the metal sheets are perforated by registering apertures ( 13 ,  14 ) which are sealed against said space along the circumference thereof, at least one ( 12 ) of the metal sheets around each aperture forming an embossment ( 15 ) attached to the other metal sheet ( 11 ) as a spacer between the metal sheets.  
     
     
         2 . The panel of  claim 1  wherein the metal sheets ( 11 ,  12 ) consist of aluminium or stainless steel.  
     
     
         3 . The panel of  claim 1  wherein the metal sheets ( 11 ,  12 ) are interconnected by welding or edge folding of the metal sheets.  
     
     
         4 . The panel of  claim 1  wherein the metal sheets ( 11 ,  12 ) are interconnected at the periphery ( 18 ) of the panel to form a hermetically sealed cassette.  
     
     
         5 . The panel of  claim 1  wherein each embossment ( 15 ) is shaped as a truncated cone.  
     
     
         6 . The panel of  claim 5  wherein each embossment ( 15 ) forms a circular flange ( 16 ) around the associated aperture ( 13 ,  14 ) said flange being plane parallel with the metal sheet ( 12 ) forming the embossment.  
     
     
         7 . The panel of  claim 6  wherein said flange ( 16 ) is attached to the other metal sheet ( 11 ) which is planar.  
     
     
         8 . The panel of  claim 5  wherein both metal sheets ( 11 ,  12 ) form an embossment  15 ,  15 ′) around registering apertures ( 13 ,  14 ) and wherein opposite embossments on one and the other plate, respectively, being interconnected at said flanges ( 16 ).  
     
     
         9 . The panel of  claim 1  wherein the bottom side of the lower metal sheet ( 12 ) including the apertures ( 13 ,  14 ) therein is topographically modified.  
     
     
         10 . The panel of  claim 9  wherein the bottom side of the lower metal sheet ( 12 ) is covered by fabric or felt attached by adhesive to the bottom side, the bottom side of said fabric or felt being topographically modified.  
     
     
         11 . The panel of  claim 1  wherein the apertures are filled with a metal wool.
