Survey on Hygienic Conditions of Central Air Conditioning Ventilation System in Public Places of Shengli Oilfield,2010

[目的]了解胜利油田公共场所集中空调卫生状况,为制定防控对策提供科学依据。[方法]2010年5～9月,随机抽取胜利油田20家公共场所的集中空调系统积尘样品,检测送风管道内表面积尘量、细菌总数、真菌总数、致病菌,送风口细菌总数、真菌总数、溶血性链球菌,冷却塔水中的嗜肺军团菌等。[结果]合计检测样品557份,合格398份,合格率为71.45%。样品合格率,写字楼为72.63%、宾馆为68.94%、商场为66.98%、医院为82.61%(P>0.05);管道积尘量为82.76%,风管内表面细菌为82.02%,真菌为91.01%,送风系统中细菌为43.43%,真菌为78.79%,β-溶血性链球菌为51.22%,冷却水嗜肺军团菌为75.00%。[结论]胜利油田公共场所集中空调卫生状况较好。

[Objective] To explore the hygienic conditions of central air conditioning system in public places, so as to provide basis for making prevention and control policies. [Methods] In May September 2010, dust samples in blast pipe were collected from centralized air ventilation system in 20 public places to be taken at random,dust quantity, the bacteri urn, fungus, bacterial pathogensin from the air pipe, the bacterium, fungus, Hemolytic Streptococcus in air diffuser, Legionella Pneumophila in water of cooling tower were tested for them. EResults2557 samples were tested, 398 were qualified, thequalified rate was 71. 15%. The qualified rate in office buildings , in hotels,shopping malls,hospitals was 72.63%, 68.94% ,66.98%,82.61%（P〉0.05） ;the qualified rate in dust quantity, bacteria in air vents,fungus in air vents,bacteria in air supply system, fungus, 13 hemolytic streptococcus, Legionella Pneumophila in water of cooling tower was 82.76% ,82.02% ,91.01%.43.43%,78. 79% ,51.22% ,75.00%. [Conclusion]The hygienic conditions of central air con dilioning system in public places is better.
