ABSTRACT
This section comprises two case studies of actual cool storage installations in commercial buildings. The first relates to an ice storage system; the second to a chilled water storage system.
CASE STUDY Is ICE STORAGE SYSTEM 2A brief analysis conducted in 1979 for a 265,000 ft , 24-story San Francisco (CA)
office tower indicated that a cool storage system could possibly provide space cooling in the most cost-effective manner (16). Two space cooling systems were designed for purposes of feasibility analysis, one using conventional water chil lers, the other using ice storage. (Chilled water cool storage was not considered due to space availability and first-cost disadvantages.) Analysis showed ice storage would be competitive with a conventional system on a first-cost basis, and far more cost-effective on a life-cycle basis due to the "time-of-day" utility rates in effect. The ice storage system is now in place and operating smoothly.
