Ⅰ级洁净手术室下限截面风速的试验研究——《医院洁净手术部建筑技术规范》修订组研讨系列课题之八

Experimental study on the lowest requirement of air velocity at operation height for class I operation room:Part 8 of the series of research practice of the revision task group of the Architectural technical code for hospital clean operating department

洁净手术室通风空调系统的运行能耗在医院运行能耗中占有相当大的比例。以实地对比试验研究为手段,对I级洁净手术室截面风速限值是否存在下调空间进行比较研究。试验结果表明,手术室截面风速下调至0.22m/s后,虽然导致动态条件下手术区浮游菌浓度上升,但从术中感染控制的角度来看,上升幅度仍处于可控制、可接受的范围内。

Energy consumption of HVAC systems for clean operation rooms contributes a considerable part of the total energy consumed by a hospital. Performs an experimental case study in a class 1 operation room to investigate the possibility of reducing the servicing airflow rate of the HVAC system. The results show that although the airborne microorganism concentration rises as the air velocity at the operation height reduced to 0.22 m/s, the surgery site infection risk is still controllable and acceptable.
