典型Ⅰ级洁净手术室空调气流组织及细菌浓度分布模拟与优化

Numerical analysis and optimization on airflow and distribution of bacteria concentration in typical Grade 1 clean operating room

以Ⅰ级洁净手术室为研究对象,应用数值计算方法研究了手术室内速度场、温度场、湿度场和细菌浓度的分布规律。分析了手术室洁净度的关键影响因素,并优化了气流组织,提出了手术室设计相对合理的送风参数、气流组织和设备布置形式。可为医院洁净手术室(I级)的空调方案设计提供依据。

Taking Grade 1 clean operating room as the study obj ect,the distributions of velocity, temperature,humidity, and bacteria concentration inside the operating room were numerically investigated.Some maj or influence factors of the cleanliness of operating room were analyzed and air distribution was optimized.Based on the computational results,the reasonable air supply parameters, the form of air distribution and equipment layout were proposed.Therefore,the present investigation can provide the theoretical reference for the design of hospital operating rooms.
