【摘要】 目的为了解哈尔滨市公共场所集中空调通风系统的污染状况,以便加强监督管理和提供清洗建议。方法本文根据北方特有冬季供暖期的特点,首次提出通过监测供暖期前后的污染情况。通过对51家商场,宾馆,超市等公共场所进行采样检测,建立北方城市特有的污染趋势变化规律。结果结果显示3月16日至3月22日的采样中,显示公共场所集中空调系统的菌落总数,送风真菌总数,风口风管积尘量100%超标,均属于中度污染和重度污染,在7月17日和8月3日的采样检测中,结果显示公共场所集中空调系统的菌落总数,送风真菌总数,风口风管积尘量总计有28.6%的超标和嗜肺军团菌检出率。结论建议最佳清洗时间为供暖期结束后,本文的检测结果和清洁工作的建议方案针对国内外其他具有冬季供暖的地区具有借鉴和大范围推广作用。更多还原

【Abstract】 Objective In order to strengthen the supervision and the provision of cleaning recommendations,this paper explored the contamination situation of central air conditioning systems in Harbin.Methods According to the central heating characteristics of northern cities in winter,the detecting time was firstly proposed to be before and after winter heating period. Through the samples testing from 51 shopping malls,hotels,supermarkets and other public places, the unique pollution trends of northern cities were established.Results The samples taken from 16th March to 22nd March showed that total bacteria,air-supply total fungi and pipeline dust were 100%over standard,and all were moderate and severe polluted.The samples taken from 17th July to 3rd August showed that total bacteria,air-supply total fungi,pipeline dust and legionella detection rate were totally 28.6%over standard.Conclusions The best cleaning time was after heating period,and the detection results and suggestions of this paper can be used in other at home and abroad areas with winter heating period.更多还原
