医院洁净手术室空调设计计算

1、医院洁净空调计算围附结构的形式采用：1 .洁净手术室内围护结构选用夹芯复合彩钢板夹层厚50mm,传热系数K=0.57kcal/(m2.h.0C)=0.66W/(m2.0C)内围护结构二侧内表面放热系数an=8.7W/(m2C)换热热阻Rn=0.115m2.C/W经计算夹芯复合板换热热阻R0=0.115X2+1/0.66=1.74m20C/W传热系数K0=1/1.74=0.58W/(m20C)2 .与污物走廊相邻的内墙(240墙)K=1.76W/(m2.0C)3 .楼面K=3.13W/(m2.0C)4 .夕卜墙(240墙)K=1.94W/(m2.0C)5 .吊顶K=1.83W/(m2.0C)6
