摘　　要：目的建立集中空调通风系统空气净化消毒装置PM10净化效率实验室评价方法。方法以空气动力学实验风洞为研究平台,发生单分散相人工实验粒子,测定空气净化消毒装置对于不同粒径实验粒子的一次通过分级净化效率,通过典型环境PM10质量浓度和分级净化效率回归方程计算集中空调系统空气净化消毒装置PM10净化效率。结果在风速≥4m/s时,与自然PM10尘净化效率相比,空气净化装置计算PM10净化效率的相对偏差<10%。结论该评价方法具有可行性并为制定集中空调通风系统空气净化装置PM10净化效率评价标准提供实验手段。Objective To establish an experimental evaluation method for PM10 removal efficiency of air-cleaning device in the central air conditioning ventilation system. Methods The classification efficiency of air-cleaning device was measured by generating monodisperse aerosol in the wind tunnel. PM10 removal efficiency of air-cleaning device in the central air-conditioning ventilation system was calculated. Results The relative deviation of PM 10 removal efficiency of air-cleaning device was less than 10% at the airflow velocity of no less than 4m/s. Conclusion The method is applicable to the evaluation of PM10 removal efficiency of air-cleaning device.
