AT-84-07-3 -- Design Considerations for Modular Glycol Ice Storage Systems PDF

The design process for cool storage in commercial, industrial, governmental, and institutional buildings, or places of assembly is reviewed with particular reference to modular ice storage using standard chillers. Decision regarding partial versus full storage, indoor versus outdoor storage location, use of heat exchangers, low temperature versus standard duct air temperatures, control options, and conventional heat versus heat pumping are discussed. An economic comparison of various alternative systems versus standard air conditioning is given. Finally, a design method, cost analysis, and detailed energy and demand calculations are presented for a specific example. The case for modular glycol ice storage systems that are not only lower in first cost than standard nonstorage chilled water systems but also lower in both demand and energy consumption is analyzed.
