【摘 要】医院手术室净化空调设计，应导入新的观点，概况如下：手术室净化空调对手术室空气途径的感染控制有效且不可替代；一个净化空调系统所负担的手术室间数宜少不宜多；引入污染度概念，在降低手术室关键区域污染度的同时，减少高净化级别手术室的送风量；引入局部强化送风的概念，即采用置换气流送风吊顶,在手术室关键区域形成单向流型气流组织，降低手术室关键区域的空气污染度；新风系统采用独立的初、中效两级过滤；采用定风量阀，以保证室内的正压分布。 采用以上新的设计观点设计的天津市某医院手术室净化空调系统于1999年底投入运行，效果良好。

    【Abstract】Hospital operation room purify air conditioning design, should be introduced new ideas, general situation as follows: the operating room air conditioning in the operating room air purification the way of infection control effectively and irreplaceable;A clean air-conditioning system of the operating room number between burden be few not; Pollution into the concept, reduce the operating room in key areas of pollution at the same time, reduce the high level of air purification operating room send; Introducing the concept of local strengthening supply air, That is the replacement air supply air condole supports, in the operating room key ChanXiangLiu form in the area of airflow organization, reduce the operating room key areas of air pollution; Fresh air system adopt independent in the beginning and effect two level filtering; Set the air valve, in order to assure indoor the normal pressure distribution. The new design ideas of the design more than a hospital operating rooms in tianjin clean air-conditioning system in operation in the end of 1999, and the result is good. ......
