<p>A device for ventilating a compartment, in which pollutants are spread and which is delimited by walls (3), a ceiling (4) and a floor (5), comprises at least one air supply means (7), which is arranged by the ceiling to blow air into the compartment, and at least one air exhaust means (9), which is arranged by the floor to draw contaminated air out of the compartment. The air supply means (7) is in the form of an elongate channel, which has a cross-sectionally arcuate channel wall (12) formed with a plurality of air outlet holes resulting in air flows perpendicular to the channel wall, and which extends along the connecting line (L) between the ceiling (4) and one of the compartment walls (3), the convex side of the channel wall (12) facing outwards, and its longitudinal edges being applied against the ceiling (4) and the wall (3) along respectively a first and a second line (respectively L1 and L2). The cross-sectionally arcuate channel wall (12) of the air supply means is so designed that the angle between that part of respectively the ceiling (4) and/or the wall (3) which is located respectively between the first line (L1) and the connecting line (L) and between the second line (L2) and the connecting line (L) and that part of the channel-wall tangent plane along respectively the first and the second line (respectively L1 and L2) which extends into the compartment, is 95-120°.</p> |
