目的了解石家庄市公共场所集中空调通风系统微生物污染状况,找出问题,分析原因,提出相应的解决方案。方法按照公共场所集中空调通风系统卫生规范要求对石家庄市公共场所集中空调连续5年进行采样检测,分别就其送风口空气、风管积尘、冷却水及冷凝水进行微生物指标检测。结果检测送风口空气75份,合格率88.0%;风管积尘387份,合格率51.9%;冷却水与冷凝水96份,合格率82.2%;并且随着时间的变化,集中空调通风系统合格率呈下降趋势。结论应加快相应法律法规的完善,加大执法力度,有的放矢;制定集中空调专属评分表,实现集中空调的量化分级,分级监管;加强培训,提高企业的自律意识。
Objective To understand the status of microbial contamination of central air conditioning and ventilation system in public places in Shijiazhuang City, find out the problems, analyze the causes and put forward the corresponding solutions. Methods According to the hygiene regulations of central air-conditioning and ventilation system in public places, the centralized air conditioners in public places in Shijiazhuang City were sampled and tested continuously for 5 years, and the microbiological indexes of air-intake air duct, dust duct, cooling water and condensed water were respectively tested. Results The air outlet air was detected 75, the pass rate of 88.0%; duct dust 387, the pass rate of 51.9%; cooling water and condensate 96, the pass rate of 82.2%; and over time, centralized air conditioning ventilation system qualified Rate showed a downward trend. Conclusion The corresponding laws and regulations should be expedited, laws and regulations should be perfected, the law enforcement should be intensified, and the target should be targeted. A centralized rating scale for air conditioners should be formulated to achieve quantitative and centralized supervision of air conditioners. Training should be strengthened to raise awareness of self-discipline among enterprises.
