    • 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 DEG .
    • 一种用于对污染物扩散并由墙壁(3),天花板(4)和地板(5)限定的隔室通风的装置包括至少一个空气供应装置(7),其由 天花板以将空气吹入隔室,以及至少一个排气装置(9),其被地板布置以将污染的空气抽出隔室。 空气供应装置(7)是细长通道的形式,其具有横截面弧形的通道壁(12),该通道壁形成有多个空气出口孔,导致空气垂直于通道壁流动,并且沿着 天花板(4)和隔室壁(3)中的一个之间的连接线(L),通道壁(12)的朝向外侧的凸出侧,并且其纵向边缘施加在天花板(4)和壁 (3)分别为第一和第二线(分别为L1和L2)。 空气供应装置的横截面弧形通道壁(12)被设计成使分别位于第一线(L1)和第二线(L1)之间的天花板(4)和/或壁(3)的那部分之间的角度, 和连接线(L)之间以及在第二线路(L2)和连接线路(L)之间以及沿着第一和第二线路(分别为L1和L2)的通道壁切线平面的延伸到 隔间为95-120度。
