Abstract
In this paper, the discharge of an experimental ice-storage tank is analyzed. The storage tank is an internal
melt-ice-on-coil system. The discharge process has been studied for different mass flow rates and supply
temperatures in the range from 10 ºC to 15 ºC. The results indicate that once the ice breaks and floats
toward the top of the tank, convection in the ice/water mixture is enhanced and the heat transfer fluid in
the top coils becomes colder than in the bottom coils. Thus, an increase of the cooling power is generally
observed around the ice-breaking point. Two correlations have been developed to reproduce the effect
of the mass flow rate and supply temperature on the discharge duration and the mean cooling power.
