Patent ID: 8480463

Claim:
A flat element ( 1 ) for thermal adjustment of indoor air in the form of a ceiling element or of a wall element, the flat element comprising: an air conduct device ( 2 ) comprising baffles ( 10 ) connected to each other and forming a closed upper surface ( 5 ), a first side wall with at least one opening ( 7 ) for inlet of air, a second side wall with at least one opening ( 8 ) for outlet of air, wherein the air conduct device ( 2 ) has a bottom side that is open, wherein the baffles ( 10 ) extend from the first side wall all the way to the second side wall; an active ceiling area ( 3 ) in the form of a sheet metal with micro-holes ( 4 ); wherein into each opening ( 7 ) for inlet of air and into each opening ( 8 ) for outlet of air a connecting pipe nozzle ( 9 ) is inserted and is essentially hermetically sealed; wherein the active ceiling area ( 3 ) terminates the air conduct device ( 2 ) at the bottom side and the air conduct device ( 2 ) and the active ceiling area ( 3 ) are essentially hermetically sealed with each other; wherein the baffles ( 10 ) when viewed in cross-section have a triangle wave shape, a multiangle wave shape or a sinuous wave shape, wherein the baffles ( 10 ) comprise a front side with a lower part ( 12 ) and a back side with a lower part ( 13 ), wherein the lower parts of the front side and of the back side are arranged angled to each other and are connected to each other to an edge forming an air conduct angle ( 11 ); wherein the front side and the back side are oriented such the air conduct angle points to the active ceiling area ( 3 ), wherein the baffles ( 10 ) generate turbulences in an air stream supplied through the at least one opening for inlet of air; wherein the first and second side walls ( 6 a ) and the edge forming the air conduct angle ( 10 ) are arranged parallel to each other.
