【摘要】：为了解南昌市2012—2014年公共场所集中空调通风系统的卫生状况,依据WS 394—2012《公共场所集中空调通风系统卫生规范》,对南昌市98套公共场所集中空调通风系统进行现场采样及检测。检测项目为新风量,风管内表面积尘量、细菌总数、真菌总数,送风中PM_(10)、细菌总数、真菌总数和β-溶血性链球菌共8项指标。结果显示,检测的98套空调通风系统中,所有检测指标均合格的有17家,合格率为17.35%。2012、2013、2014年各类公共场所集中空调通风系统的合格率分别为3.57%(1/28),11.11%(5/45)和44.00%(11/25),合格率逐年升高,差异有统计学意义(χ~2=17.313,P0.05)。2014年通风系统送风中PM_(10)合格率高于2013、2012年,2014、2013年送风中细菌总数合格率均高于2012年;2013年风管内表面积尘量合格率高于2014、2012年,风管内表面细菌总数及真菌总数合格率均逐年升高;上述差异均有统计学意义(P0.05)。提示南昌市公共场所集中空调通风系统的卫生状况逐年好转,但总体合格率仍较低。
[Abstract]:In order to understand the hygienic status of central air conditioning and ventilation system in public places in Nanchang from 2012 to 2014,According to WS394-2012 "hygienic specification for centralized air conditioning ventilation system in public places", 98 sets of centralized air conditioning ventilation systems in public places in Nanchang city were sampled and tested on the spot.The test items were fresh air volume, air duct surface area dust, total bacteria, total fungi, PMSP 10, total bacteria, total fungi and 尾 -hemolytic streptococcus.The results showed that 17 of the 98 air conditioning ventilation systems tested were qualified, with a qualified rate of 17.35.2012and 2013.In 2014, the qualified rates of central air conditioning and ventilation systems in various public places were 3.571.28 / 11.115.45) and 44.00 / 11 / 2525, respectively, and the qualification rate increased year by year.The qualified rate of PMSP 10 in ventilation system in 2014 was higher than that in 2013, and the qualified rate of bacteria in 2013 was higher than that in 2012, and the qualified rate of dust content in air duct in 2013 was higher than that in 2014 and 2012, respectively.The total number of bacteria and the qualified rate of the total number of fungi on the inner surface of the duct increased year by year, and the above differences were statistically significant (P 0.05).It is suggested that the hygienic condition of central air conditioning and ventilation system in public places in Nanchang is improving year by year, but the overall qualified rate is still low.
