Abrégé

The invention relates to an air outlet (1, 1'), comprising a connecting piece (2) for the at least indirect connection to an air supply system, a housing (4) delimiting an air distribution chamber (7), and a perforated plate (5) forming an effective air discharge cross-section (10) of the air outlet (1, 1'), wherein a center line (9) of the connecting piece (2) is oriented perpendicular to the perforated plate (5). Starting from a center region of the housing (4), in which the connecting piece (2) empties into the air distribution chamber (7), walls (11) of the housing (4) that face the perforated plate (5) wrap around and extend in the direction of the perforated plate (5), inclined at an acute angle α in relation to the perforated plate (5). The invention further relates to a suspended ceiling or a wall paneling, and to a method for producing a previously described air outlet (1, 1'). In order to refine the air outlet known from the state of the art regarding the flow behavior of the escaping air, and in order to improve the optical properties and provide a simplified method for producing an air outlet, according to the invention the perforated plate (5) is a panel (6) of a louvered ceiling or a wall paneling.

Abrégé

The invention relates to an air outlet (1, V), comprising a connecting piece (2) for the at least indirect connection to an air supply system, a housing (4) delimiting an air distribution chamber (7), and a perforated plate (5) forming an effective air discharge cross-section (10) of the air outlet (1, 1'), wherein a center line (9) of the connecting piece (2) is oriented perpendicular to the perforated plate (5). Starting from a center region of the housing (4), in which the connecting piece (2) empties into the air distribution chamber (7), walls (11) of the housing (4) that face the perforated plate (5) wrap around and extend in the direction of the perforated plate (5), inclined at an acute angle α in relation to the perforated plate (5). In order to refine the air outlet known from the state of the art regarding the flow behavior of the escaping air, according to the invention a transition piece (3) is disposed between the housing (4) and the connecting piece (2), the cross-sectional surface of the transition piece, perpendicular to the flow direction, being larger than the cross-sectional surface of the connecting piece (2), wherein the transition from the connecting piece (2) to the transition piece (3) exhibiting an erratic change in the cross-section.
