    • The work surface to be protected (1) is cleared and accessible both from above (102) and at least on one side, called the free side (100). The method is characterised in that clean air is continuously blown above the work surface (1) from the side (101) opposite the free side (100), in the form of a substantially horizontal flux that sweeps across the work surface (1), towards the free side (100), and which has a speed gradient such that the upper layer - or top stream - (V1) has a speed substantially greater than the air flowing in the proximity of the top surface (10) of the work surface (1); the totality or the main part of the flux is drawn from the free side (100), by means of a suction vent (20) extending along and immediately adjacent to the edge (10b) of the work surface (1). The invention is useful for protecting a fixed or mobile surface supporting various articles sensitive to the contamination of the ambient air.
    • 要保护的工作表面(1)从上方(102)和至少一侧称为自由侧(100)都可以清除和接近。 该方法的特征在于,清洁空气以扫过工作表面(1)的大致水平通量的形式从与自由侧(100)相对的侧面(101)连续地吹向工作表面(1)上方, 朝向自由侧(100),并具有速度梯度,使得上层 - 或顶层 - (V1)的速度基本上大于在工作表面的顶表面(10)附近流动的空气 (1); 通过沿着工作表面(1)的边缘(10b)延伸并且紧邻工作表面(10b)的吸入口(20),从自由侧(100)抽出助焊剂的总体或主要部分。 本发明可用于保护支撑各种对环境空气污染敏感的物品的固定或移动表面。

    • An arrangement for supplying air to a room, preferably a clean room, which is divided into zones (A, B, C) with different climatic requirements, comprises a first air treatment unit (11) for supplying air to a pressure chamber (5) which is shared by a plurality of zones and from which air is supplied to the various zones. The arrangement also comprises at least one mixing space (14) communicating with the pressure chamber (5) and a second air treatment unit (17). The mixing space is intended for mixing of the air from the first (11) and the second (17) air treatment unit. The mixing space also communicates with at least one of the zones (B) for supplying the mixed air to this zone (B).
    • 用于将空气供应到不同气候要求的区域(A,B,C)中的房间,优选洁净室的布置包括:用于向压力室(5)供应空气的第一空气处理单元(11) 其由多个区域共享,并且空气从该区域供应到各个区域。 该装置还包括与压力室(5)连通的至少一个混合空间(14)和第二空气处理单元(17)。 混合空间旨在混合来自第一(11)和第二(17)空气处理单元的空气。 混合空间还与用于将混合空气供应到该区域(B)的区域(B)中的至少一个连通。
