Abstract:	A new device of ice melting with performance improved has been developed by complete removal of melt to produce chilled air during on-peak power consumption. Energy equations have been derived, from the integral boundary-layer analysis, for estimating the thickness of the ice melted and the thermal penetration distance in ice layer region with convective boundary condition on free surface. Numerical examples have been illustrated in which the air temperature was specified and varied with time to simulate practical systems.Results show that complete removal of melt in cool-thermal discharge systems can enhance the flux of discharge due to heat transfer being much easier than that in the systems without removal of melt. Therefore, considerable improvement in performance of cool thermal discharge can be accomplished if the system is operating with rather than without complete removal of melt.
