    Hygienic Evaluation of the Central Air Conditioning and Ventilation System of an Institution

      摘要
    • 摘要:
      目的 调查某单位集中空调通风系统卫生状况，为卫生管理提供依据。
      方法 参照《公共场所集中空调通风系统卫生规范》（WS 394-2012）和《集中空调通风系统卫生管理规范》（DB 11/485-2011），对集中空调通风系统进行现场监测。
      结果 集中空调通风系统送风口PM2.5合格率为75%，细菌总数不合格率为100%；送风口PM10和真菌总数，空调风管积尘量、细菌总数、真菌总数和冷却水嗜肺军团菌均符合卫生标准。
      结论 该单位的集中空调通风系统存在一定程度的污染和卫生隐患，需加强集中空调通风系统的清洗和消毒工作并定期卫生检测。

       

      Abstract:
      Objective To investigate the hygienic quality of the central air conditioning and ventilation system in an institution, and to provide a basis for operation safety management.
      Methods According to the Hygienic Specification of Central Air Conditioning and Ventilation System in Public Buildings (WS 394-2012) and the Hygienic Management Regulations for Central Air Conditioning and Ventilation System (DB 11/485-2011), samples from the central air conditioning and ventilation system in the institution were collected and measured on site.
      Results The pass rate of PM2.5 was 75% in the air outlets of the system. The count of bacteria failed to reach the standard in any air outlet. The indicators meeting the hygienic standard included PM10 and fungus count in the air outlets, and dust deposition, bacterial count, and fungus count in the duct, as well as Legionella pneumophila in the cooling water.
      Conclusion There is some extent of contamination and hidden hygienic trouble in the central air conditioning and ventilation system of the institution. Cleaning and disinfection of the system should be strengthened.
