    Hygienic Status of Central Air-conditioning Ventilation System in Public Places of Sichuan

      摘要
    • 摘要:
      目的 调查2011-2014四川省年公共场所集中空调通风系统卫生现状和变化趋势,为卫生管理提供依据。
      方法 随机抽取全省65家公共场所集中空调通风系统,检测风管内表面积尘量、风管内表面细菌总数和真菌总数含量、冷却水中嗜肺军团菌。
      结果 2011-2014年集中空调抽检样品合格率分别为73.75%、83.33%、93.33%、78.33%,2014年合格率明显低于2013年(P<0.05)。风管内表面积尘量、细菌总数、真菌总数合格率分别为90.77%、67.69%、78.46%,风管内表面细菌总数合格率低于积尘量(P<0.05);且三项指标中每两项之间存在正相关关系(P<0.05)。商场冷却塔中军团菌检出率(21.87%)高于酒店(未检出;P<0.05)。
      结论 四川省公共场所集中空调通风系统卫生状况有恶化的趋势,卫生管理部门应该引起重视。同时考虑调整检测指标,优化评价体系。

       

      Abstract:
      Objectives To investigate the hygienic status and the trend of variation in central air-conditioning ventilation system in public places of Sichuan province in 2011-2014.
      Methods Central air-conditioning ventilation system in 65 public places were randomly selected in Sichuan province to detect the accumulated dust, total bacteria, and total fungi on the inner surface of ventilation duct and the pollution of Legionella pneumophila in cooling water.
      Results The qualified rates of samples collected in 2011, 2012, 2013 and 2014 were 73.75%, 83.33%, 93.33% and 78.33% respectively, and the qualified rate in 2014 was significantly lower than that in 2013 (P<0.05). The qualified rates of accumulated dust, total bacteria counts, and total fungi on the inner surface of ventilation duct were 90.77%, 67.69% and 78.46% respectively; and the qualified rate of total bacteria counts was lower than that of accumulated dust. There was a positive correlation between each of two indicators in these three indicators. The detection rate of Legionella pneumophila in water in the cooling tower of markets (21.87%) was higher than that of hotels 0% (P<0.05).
      Conclusions More attention should be paid to the hygienic status of central air-conditioning ventilation system in public places to prevent the trend of deterioration; and more work should be done to adjust detection indeces and optimize evaluation system.
