哈尔滨市集中空调污染状况调查

Investigation of Central Air Conditioning Systems in Harbin

目的为了分析空调污染情况和传染病发病情况的关系,以便指导空调清洗和疾病预防。方法通过对10家商场、宾馆、超市等公共场所分别在冬季供暖开始前和结束前进行集中空调通风系统卫生指标采样检测,并分析2006-2010年的传染病发病情况分析。结果哈尔滨冬季供暖期结束前的风管内积尘量、细菌总数、真菌总数的超标情况要比冬季供暖期开始前的严重,且传染病发病人数在5-7月份出现一个高峰期。结论空调在供暖期处于停用的状态,风管内经过半年左右沉积了很多灰尘和微生物,在供暖期刚刚结束的一段时间,沉积的灰尘和微生物随送风进入各个公共场所。在供暖期结束后集中空调使用频率较高,同时供暖期结束后的几个月是传染病发病人数较其他月份高,建议供暖期结束前后对集中空调进行清洗。
