通过粒度和气流阻力对现场去除效率的一般通风过滤装置和系统进行现场试验

[中文适用范围]： 本文件描述了测量通用通风空气净化设备在最终使用安装配置中的性能的程序。 性能测量包括颗粒尺寸的去除效率和气流阻力。 测试程序包括系统气流的定义和报告。 该程序描述了一种对正常运行的空气处理系统中就地空气净化器上游和下游的 0.3 μm 至 5.0 μm 周围空气颗粒进行计数的方法。 该过程描述了粒子计数器数据的减少，以计算颗粒尺寸的去除效率。 由于过滤器安装在设计和形状上差异很大，因此包括用于评估过滤器评估和系统评估场地的适用性的协议。 当评估的现场条件满足为系统评估制定的最低标准时，也可以根据此程序进行系统的性能评估。 本文件还描述了测试设备的性能规格，并定义了计算和报告结果的程序。 本文件不适用于测量便携式或可移动室内空气净化器的性能，也不适用于评估在 0.4 μm 测量时预期过滤效率等于或高于 99% 或等于或低于 30% 的过滤器安装。 [外文原描述]： This document describes a procedure for measuring the performance of general ventilation air cleaning devices in their end use installed configuration. The performance measurements include removal efficiency by particle size and the resistance to airflow. The test procedures include the definition and reporting of the system airflow. The procedure describes a method of counting ambient air particles of 0,3 μm to 5,0 μm upstream and downstream of the in-place air cleaner(s) in a functioning air handling system. The procedure describes the reduction of particle counter data to calculate removal efficiency by particle size. Since filter installations vary dramatically in design and shape, a protocol for evaluating the suitability of a site for filter evaluation and for system evaluation is included. When the evaluated site conditions meet the minimum criteria established for system evaluation, the performance evaluation of the system can also be performed according to this procedure. This document also describes performance specifications for the testing equipment and defines procedures for calculating and reporting the results. This document is not intended for measuring performance of portable or movable room air cleaners or for evaluation of filter installations with an expected filtration efficiency at or above 99 % or at or below 30 % when measured at 0,4 μm.
