| Abstract: | A mathematical model to simulate the production of chilled air during on-peak power consumption hours in cool–thermal discharge systems with external recycle under melt removal and varied flow rate of flowing air has been developed theoretically. Equations have been derived for estimating the controlling air flow rate when the outlet chilled air temperature is specified. Three cases of inlet ambient temperatures of flowing air were illustrated to study the influence of recycle ratio on the performance improvement of cool–thermal discharge systems, the volumetric flow rate variations and Nusselt number increment due to a larger convective heat transfer rate were also delineated. |
