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.
