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3.0m的Ⅰ级洁净手术室,为了在距地面1.2m高的送风面投影区域获得0.20～0.25m/s的工作区平均风速,送风速度需要达到0.30～0.37m/s,送风量需要达到6 800～8 400m3/h。
The revised “Technical Specification for Construction of Clean Operating Surgery Department of the Hospital” (draft for approval) has adjusted the average height of the wind speed detecting section and the average wind speed of the working area in the operating room of Class I clean operating room. In order to obtain the corresponding work area average wind speed corresponding to the air supply speed and air supply, a theoretical study concluded that the following: for the level of 3.0m clean class Ⅰ operating room, in order to 1.2m high from the ground to send The average wind speed in the working area of 0.20 ~ 0.25m / s is obtained in the projection area of the wind surface. The blowing speed needs to reach 0.30 ~ 0.37m / s and the blowing volume needs to reach 6 800 ~ 8 400m3 / h.
