通风屋顶间层内空气流速对空调冷负荷的影响

The effect of air velocity on air conditioner cooling load of ventilation roof

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 .

Thermal process of ventilation roof which is common in China's southern regions is simulated in this paper.Attention is paid to the effect of air velocity on air conditioner cooling load and the relation of cooling load to air velocity is derived.The results show that it is not a good idea to lower cooling load by increasing air velocity.
