Research on Layered Air Conditioning Design for Ball Sports Hall in a University in Fuzhou

结合具体工程,通过负荷计算和CFD气流组织模拟,验证对气流速度要求比较高的羽毛球场、乒乓球场空调采用中下送中回的气流组织;实现了高大空间采用分层空调减少空调、冷负荷的目标,且温度分布均匀、风速控制较好,可供相关工程参考。

Stratified air conditioning in large spaces can reduce the cooling load of air conditioning,and the air conditioning of badminton courts and table tennis courts has high requirements for air velocity(the air velocity of badminton courts below 9m from the ground and table tennis courts below 3m from the ground shall not be greater than 0.2m/s).The research object of this paper is a university ball stadium.The stadium is a tall space,including badminton area and table tennis area.It adopts the form of stratified air conditioning,and the air distribution adopts the form of middle down delivery and middle return.Through the load calculation and CFD air distribution simulation analysis,it is verified that the air distribution adopts the mode of sending air from the middle down and returning air from the middle,which not only achieves the goal of reducing the cooling load of air conditioning in stratified air conditioning,but also has uniform temperature distribution and good wind speed control.
