摘要:
在稳定污染源条件下测试了不同风量时空气净化器进出风口处和试验舱内的颗粒物浓度,分析了净化器的一次净化效率和室内颗粒物的浓度衰减过程.结果表明,净化器低档和高档风量时PM2.5净化效率分别为55.1%和59.4%,PM10净化效率分别为57.2%和61.2%,高档风量的一次净化效率比低档风量的一次净化效率约高4%; 测得的净化效率与室内颗粒物浓度拟合曲线推算得到的一次净化效率吻合较好; 由颗粒物发生量和净化效率导出的颗粒物浓度衰减方程,与由室内颗粒物浓度拟合得到的浓度衰减方程均能准确反映净化过程中室内颗粒物浓度的指数衰减特征; 净化器适用面积不仅取决于净化性能,还与初始浓度、单位面积污染物释放量有关.
Abstract:
Particulate concentrations in the inlet and outlet of air cleaner and in the chamber with steady pollutant source were measured for different airflow rates of air cleaner to analyze the single-pass removal efficiency of air cleaner and the decay characteristic of indoor particulate concentration. The removal efficiencies of PM2.5 for small or large airflow rate are 55.1% and 59.4% respectively, and the removal efficiencies of PM10 for small or large airflow rate are 57.2% and 61.2% respectively. The single-pass removal efficiency of air cleaner for large airflow rate was 4% higher than that for small airflow rate. The particulate removal efficiencies tested agree well with those inferred from the fitting curves of indoor particulate concentration. The equations for particulate concentration decay can be deduced from particulate emission rate and particulate removal efficiency, and can also be obtained by fitting the indoor concentration. Both equations can accurately reflect the exponential decay of particulate concentration during air cleaning. The effective room size depends not only on the performance of air cleaner, but also on the initial concentration and the particle emission rate per unit area of the room.
