摘要：
在面积9 m2、高2.5 m的血液病房样板间中进行了实验。在顶部送风尺寸每边比床边外延0.4 m的条件下，室内达到远低于3.5粒/L浓度的5级洁净度要求；床面0.4 m以上床头位置风速低于0.1 m/s，远低于避免吹风感的0.12 m/s要求；可比常规做法节能1/3~2/3。

Abstract：
Performs an experiment in a model hematology ward with an area of 9 m2 and a height of 2.5 m. The results show that the cleanliness can be reached class-5 (indoor particle concentration much lower than 3.5 particles/L) when each side of top concentrated air supply ceiling is 0.4 m longer than the bedside. Meanwhile, the air velocity at 0.4 m height of bed head is lower than 0.1 m/s, which is far below blowing feeling velocity of 0.12 m/s. In addition, this air supply model can save 1/3 to 2/3 energy than regular project.
