Abstract

L'invention concerne une installation de diffusion de flux d'air permettant de diffuser de l'air dans un volume localisé, ladite installation comprenant une surface de travail (40), des moyens de diffusion (2) de flux d'air, et des parois de guidage (3) transparentes longitudinales et écartées de la surface de travail. Ladite installation comprend des moyens d'aspiration (5) de chaque côté longitudinal de la surface de travail, et lesdites parois de guidage comprennent au moins deux parois de guidage (31 ) extérieures, et deux parois de guidage (30) intérieures qui s'étendent entre les parois de guidage (31) extérieures. Lesdites parois de guidage et lesdits moyens de diffusion (2) sont agencés de telle sorte que le flux (8) d'air diffusé est réparti en un flux d'air central, diffusé entre les parois de guidage intérieures, un flux d'air latéral, diffusé entre chaque paroi de guidage intérieure et la paroi de guidage extérieure correspondante, et un flux (82) d'air extérieur à chaque paroi de guidage (31) extérieure.
