Research on Layered Air Conditioning Design for Ball Sports Hall in a University in Fuzhou
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 ta-ble 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 stadi-um.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 a-nalysis,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 dis-tribution and good wind speed control.
