Operation and performance of commercial cool storage systems

EPRI initiated the Commercial Cool Storage Field Performance Monitoring Project (RP2732-05) to provide cool storage system performance data for use in improving system design, operation and economics. In cooperation with twelve participating utilities, cool storage systems were monitored and analyzed at six commercial buildings in 1987 and at seven buildings in 1988. This final report discusses the impacts of monitored cool storage systems on site electric demand and energy use patterns. The chiller and auxiliary equipment energy consumption and storage tank thermal performance are discussed for chilled water, eutectic salt and ice storage systems. A conventional air conditioning system is simulated for each site and its performance is compared with the cool storage system's monitored performance. Recommendations are made to utilities and system designers to help their customers improve system performance and operation. 3 refs., 10 figs., 5 tabs.
