Summary

In this study, theoretical evaluation of performance of three ice based cool thermal energy storage systems is conducted: (a) static, indirect, external melt ice-on-coil; (b) dynamic ice slurry type storage with a water; and (c) ice slurry distribution system. In order to investigate and assess possible economic and energy saving potential of an ice slurry storage system over conventional static type a computer simulation models were used. The systems were compared for high temperature application, for the purpose of milk cooling in the dairy industry. The product temperature that has to be achieved is 3°C which requires a secondary coolant temperature to be less than 1°C. Calculations have been performed on basis of specific user supplied load data for a design day, acquired as an actual case for dairy plant Prehrambeno industrijski kombinat in the city of Rijeka, Croatia, and local electricity billing rate structure. The comparison shows that the dynamic cool thermal energy storage system is favourable as to energy consumption in all studied cases.
