Post evaluation of top ventilator project;
对应用屋顶通风器工程项目的后评价
Thermal process of ventilation roof which is common in China s southern regions is simulated in this paper.
对我国南方地区常用的通风屋顶热状况进行了数值模拟分析 ,探讨了架空间层内空气流速对空调冷负荷的影响 ,并给出了空调日平均冷负荷随架空层内空气流速的变化关系式 ,指出试图通过加强通风屋顶间层入口空气流速来降低连续空调冷负荷的措施是不可取的 。
In this paper, the structure of roof fan has been improved and designed through the analysis of the leaking theory of roof fan.
通过对屋顶风机漏雨理论的分析,对屋顶风机的结构进行了改进设计,该设计方法使屋顶风机的漏雨问题得到有效的解决。
This paper mainly introduces the frequency control technique and technical innovation for large-type roof fan.
