        摘要:

        提出把空气净化装置主要设于回风口以拒尘、菌的主动式污染控制理念和方法,得出这样的装置必需具备三个必要条件:初阻力不大于20 Pa,滤菌效率不小于90%,除尘计重效率不小于95%(或对于粒径大于等于0.5 μm微粒的计数效率不小于70%)。

        关键词:空气净化装置,主动式污染控制,回风口,初阻力,过滤效率

        Abstract:

        Provides an initiative contamination control concept and method with return air inlet cleaning devices to prevent airborne particles and microbes from entering air ducts, from which concludes the three essential conditions of the cleaning devices: the preliminary resistance should be not greater than 20 Pa; the filtration efficiency of microorganism should be not less than 90%; and the weighing filtration efficiency of dust should be not less than 95% or the counting filtration efficiency for the particles of not smaller than 0.5 μm should be not less than 70%.
