Title: Assessment of cool storage in commercial building applications

Cool storage can be used for electrical load leveling in commercial building applications. Analysis of conventional chilled-water and ice-storage systems indicates that payback periods, relative to nonstorage systems, of less than four years are available under the partial-storage, or load-leveling, mode of operations. Storage systems with sufficient capacity to eliminate completely on-peak operation of the refrigeration systems entail larger initial capital outlays and longer paybacks under existing commercial-class electric rate schedules. Better storage performance and lower costs could be achieved through improved matching of the storage and the refrigeration systems and through improved latent-heat storage systems.
