Ⅰ级洁净手术室送风速度的探讨——《医院洁净手术部建筑技术规范》修订组研讨系列课题之五
Discussion on air supply velocity of the class Ⅰ clean operating room
摘要：
修编的《医院洁净手术部建筑技术规范》(报批稿)对Ⅰ级洁净手术室工作区平均风速的检测断面高度和工作区平均风速均有调整。为了获得相应的工作区平均风速对应的送风速度和送风量，进行了理论研究，得出如下结论：对于层高为3.0 m的Ⅰ级洁净手术室，为了在距地面1.2 m高的送风面投影区域获得0.20～0.25 m/s的工作区平均风速，送风速度需要达到0.30～0.37 m/s，送风量需要达到6 800～8 400 m3/h。
Abstract：
The revised code adjusts the average air velocity and the measure section height for the velocity in working area in the classⅠclean operating rooms. Carries a theory research in order to obtain air supply velocity and air supply rate corresponding to average air velocity in working area. The results show that the air supply velocity should be up to 0.30 to 0.37 m/s and the air supply rate should be up to 6 800 to 8 400 m3/h for the classⅠclean operating rooms, whose storey height is three meters, in order to obtain the average air velocity of 0.20 to 0.25 m/s in the projection area of air supply face at 1.2 meters from the floor.
