A strategy that may provide economic benefits in buildings is to use an ice production system to provide cool storage for later use when cooling is needed. Understanding the fundamental dynamics of the storage tank is critical in determining the feasibility of such strategies. For this purpose, a lumped parameter model of ice growth on a heat exchanger submerged in a water storage tank is described. Results of an experimental study of an ice storage system installed in a residential research facility are also presented. The results of a parametric study are also presented that show some of the effects of geometric and operating variables on system performance. Trends exhibited in the results suggest ways to optimize ice production for the particular heat exchanger geometry studied.
