摘　　要：本文调查了北京市12栋大型公共建筑(酒店(含餐饮)、商场(含超市)、写字楼、体育馆和医院等)集中空调通风系统的污染状况,并利用统计分析软件SPPS 16.0对风管内表面、送风及室内的9项污染指标进行了相关性分析。研究结果表明:风管内表面积尘量与积尘细菌、送风PM10和室内PM10、送风微生物含量和室内微生物含量均存在极显著的正相关。因此,可通过控制风管内表面积尘量和送风质量来减少积尘细菌含量,提高室内空气质量。In this paper,the pollution situation of central air-conditioning and ventilating systems employed in 12 large-scale public buildings（such as hotel,supermarket,office building,gymnasium and hospital） in Beijing was investigated.And then,the correlation analysis of 9 indexes for duct interior surface,supply air and indoor air was carried out with the statistical analysis software of SPSS 16.0.The results indicated that significant positive correlations existed between the following indexes,dust and bacteria accumulated on the duct interior surface,PM10 concentration in supply air and indoor air,airborne bacteria concentration in supply air and indoor air.Therefore,the indoor air quality would be improved by controlling the dust and microorganisms accumulated on the duct interior surface and the quality of supply air.
