The effect of recycle on cool-thermal discharge systems by melting ice with producing chilled air

A new device of cool-thermal discharge systems of melt removal with external refluxes at both ends, resulting in substantially improving the heat-transfer efficiency, has been proposed and formulated mathematically to simulate the outlet air temperature of the chilled air produced during on-peak power-consumption hours. The numerical results are represented graphically and compared with that in an open duct of same size without recycle. Equations have been derived for estimating the thickness of the mass airflow rate, the thickness of melted ice and the total amount of cool thermal flux during the operating process with inlet air temperature or outlet air temperature specified. Numerical examples have been illustrated in which either the inlet air temperature or outlet air temperature was given, and the results of cool-thermal discharge fluxes have been also discussed.
