Baltimore Aircoil Company (BAC) ice storage test report
The Ice Storage Test Facility (ISTF) is designed to test commercial ice storage systems. Baltimore Aircoil Company (BAC) provided a storage tank equipped with coils designed for use with a liquid overfeed refrigeration system. Separate coils were also supplied for use with a secondary fluid system. The BAC ice storage system was tested over a wide range of operating conditions. System performance was satisfactory under both charging and discharging conditions. During the liquid-overfeed ice build cycle, the evaporator temperature closely matched the manufacturer's literature. The measured average brine temperatures were slightly higher than those given in the BAC literature (i.e., the BAC report is conservative). During discharge cycles, the storage tank outlet temperature remains nearly constant below 35{degree}F, rising only after most of the ice has been melted. The discharge performance was relatively unaffected by discharge rates or tank inlet temperatures. Based on these tests, a storage tank sized solely according to the latent ice storage capacity is capable of providing a relatively constant temperature to the load throughout most of the discharge cycle. This report describes BAC 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. 10 refs., 30 figs., 7 tabs.
