Presents results generated from the IceTES computer program, which was developed to predict the dynamic performance of ice-on-pipe brine thermal energy storage system. A set of parametric studies is presented to show the predicted trends during both charge and discharge cycles. The qualitative behaviour for the brine outlet temperature, charge or discharge rate, and state of charge is displayed for a typical thermal storage system. To validate the model, performance predictions generated with IceTES are compared to experimental data from a national laboratory for two ice thermal storage systems. The predicted and measured results for the brine exit temperatures and load profiles are in good agreement throughout most of the charge and discharge cycles. Additional results are presented to show a complete system simulation for a typical day in which the thermal energy storage component is coupled with a chiller and load.KEYWORDS: year 1996, brine, energy storage, ice storage, algorithms, validating, computer programs, calculating, performance, comparing, experiment, measuring, accuracy
