外科手术室污染控制的数值模拟分析

就变化风速的送风口所产生的气流流型对外科手术室内的细菌浓度和人体热舒适的影响进行了数值模拟分析。研究表明,与通常采用的均匀风速的送风口相比,变化风速的送风口对于降低手术室工作区细菌浓度,防止病人手术切口及手术器械等被回风气流携带的浮游细菌再次感染,以及减少手术室的送风量等方面具有明显的优点。

NUMERICAL SIMULATION OF CONTAMINANT CONCENTRATION CONTROL FOR OPERATING ROOMS

With numerical simulation method the effect of the airflow pattern created by the air inlet of varying velocity on contaminant concentration and thermal comfort in an operating room was investigated.The research results show that compared with uniform inlet velocity profile,the air inlet of varying velocity profile has more advantages to get lower contaminant concentration,to prevent patient & operating apparatus in the operating area from infection with airborne disease germs and to reduce the airflow rate needed for pollutant concentratin control.
