Abstract
A supply air terminal device (1) of box-like or screen-like construction has a front wall (5) in which there are disposed a plurality of groups (10) of slots (7) with the groups and the slots in each group mutually spaced apart. Each group of slots is allocated a nozzle module (11) mounted on the inside of the wall (5). Each nozzle module (11) includes a number of nozzles (12) corresponding to the number of slots, wherein each nozzle functions to repeatedly deflect the part-flows (B) through an angle of 90.degree. from a delivered main flow. To this end, each nozzle (12) of a nozzle module (11) carries at its ends curved deflecting parts (12b) which project progressively further out in the direction of the main flow. The deflected part-flows mutually collide and exit with a low impulse through the slots (7) allocated to respective nozzles (12). The invention also relates to a nozzle module for a supply air terminal device (1) of the aforesaid kind.
