城市轨道交通通风系统空气净化设备性能检测研究

Performance Detection of Air Purification Equipment in Ventilation system of City Subway

依据《公共场所集中空调通风系统卫生规范》(2006),对K市地铁已投入使用的空气净化设备(A)和即将在S市和K市地铁中使用的2套空气净化设备(B和C)进行了验收检测。结果发现,采用静电式空气净化器作为净化单元的3套设备颗粒物净化效率都能达到标准要求,净化率接近或超过70%。设备C微生物去除效率超过70%,而配置紫外灯的设备A和B微生物去除效率均大于90%,其它卫生安全方面的指标均符合要求。这种大型空气净化设备的现场检测在国内极为少见,这次的成功检测为今后进行类似检测提供了重要的参考和借鉴。

According to《Health standard of air conditioning ventilation systems in public places》（2006）,A set of air purification equipment（A） used in K city subway and two sets of air purification equipment（B and C） that will be used in S and K city subway were tested.The result showed that the particle removal efficiency of three sets of equipment that used electrostatic air cleaner as the purification unit achieved the standards,more than 70%.Microbial removal efficiency of C was more than 70% and those of A and B with UV light were more than 90%.Several other indictors about safety and health agreed with the standards.The detection of such large-scale purification equipment in China is extremely rare,and important reference and experience was provided for future similar detection because of this successful detection.
