摘要
可吸入粒子是病毒细菌的载体,但通风空调系统往往仅对大粒子有明显的清除效果,为此空调和自然通风房间开始逐步使用空气净化器消除小粒子对人体健康的危害。本文通过对不同安放位置和不同工况条件下运行的空气净化器对室内粒子实际去除效率进行实验研究,结果表明,净化器的循环风量是影响粒子去除效率的主要原因。尽管高风速情况下净化器的粒子捕集效率下降,就整个房间粒子清除效果而言,循环风量较大时,房间空气净化效果较好。
Inhalable particle used to be carriers of virus and bacteria, in general HVAC systems, remarkable clearness effects can only be observed when dealing with rough particles, therefore air purifier are gradually applied in HVAC & natural ventilated rooms to reduce the harm of fine particle to human health. Air purifier located in varied locations and operates in varied conditions are analyzed in experiments to determine the actual particle removal efficieneies in this article. As is turned out, volume of circulated air is the principle factor among those influence particle removal efficiencies. Particle trapping efficiency of air purifier will reduce as wind speed accumulates; however, as is concerned to particle removal effects of the whole room, increased volume of circulated air can bring better air purifier performance.
