This papers analyses the factors affecting the diffuser design in a stratified chilled-water storage tank

and the diffuser is one of most important factors.So introduces the design principles and basic assumptions of diffuser.The diffuser was designed on an example and taken experiments on a laboratorial stratified chilled-water storage tank in 110 minutes.By testing the diffuser

the stratfied chilled-water storage tank can work efficiently and economically with the requirement of the chiller's design characteristics.
