摘要A mathematical model of cool-thermal discharge systems with external recycle by melting ice with producing chilled air to supply on-peak daytime air-conditioning needs was developed and studied analytically. The estimation of the outlet chilled air temperature and air mass velocity with convective transfer on free water surface under air time-velocity variations for specified inlet temperatures was illustrated. Theoretical results show that the recycle effect can effectively enhance the heat transfer efficiency compared with that in the device without recycle. Three numerical examples of ambient air temperatures varied with time in practical systems were simulated, and the result of air mass velocity with air traversed length as a parameter was also delineated.
