COOL THERMAL DISCHARGE OBTAINED WITH AIR FLOWING OVER MELTING ICE

A model of ice melting has been developed to produce chilled air durin g on-peak power consumption. Equations have been derived for estimatin g the thickness of the melted ice and the temperature distribution in the liquid region with convection boundary condition. Three test cases have been studied in which the air temperature was specified and vari ed with time. Results are given for the thickness of the melted ice la yers for cool thermal discharges. The cool thermal discharge and the p enetration distance for ice melting, increase with air velocity, espec ially at low velocities of about 10 m/s; they decrease weakly as the l ength traversed by air increases.
