摘　　要：在面积9m^2、高2.5m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0.4m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0.4m以上床头位置风速低于0.1m/s,远低于避免吹风感的0.12m/s要求;可比常规做法节能1/3~2/3。Performs an experiment in a model hematology ward with an area of 9 m^2 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.
