The Ice Storage Test Facility (ISTF) is designed to test commercial ice storage systems. Calmac provided a storage tank equipped with coils designed for use with a secondary fluid system. The Calmac ice storage system was tested over a wide range of operating conditions. Measured system performance during charging was similar to that reported by the manufacturer. Both the measured average and minimum brine temperatures were in close agreement with Calmac's literature values, and the ability to fully charge the tank was relatively unaffected by charging rate and brine flow rate. During discharge cycles, the storage tank outlet temperature was strongly affected by the discharge rate. The discharge capacity was dependent upon both the selected discharge rate and maximum allowable tank outlet temperature. Based on these tests, storage tank selection must depend most strongly on the discharge conditions required to serve the load. This report describes Calmac system performance fully under both charging and discharging conditions. Companion reports describe ISTF test procedures and ice-making efficiency test results that are common to many of the units tested. 11 refs., 31 figs., 9 tabs.
