Peak shifting potential of ice-making thermal energy storage systems for residential cooling
This paper describes the simulation and analysis of the load-shifting potential of ice-making or chilled water thermal energy storage (TES) systems for residential cooling. Histograms of the time-of-day average electrical demand over a cooling season are presented for three system configurations and load management strategies. The histograms are analyzed for load-shifting capability, total energy consumption and utility/customer benefits. Simulations are presented for a conventional airconditioning system providing cooling on demand, a conventional system with an externally controlled management device to limit demand onpeak, and an ice-making storage system. Results indicate that although there is a significant impact of the system configuration on the load-shifting potential, it is the heat pump performance that is critical. For ice-storage systems to be attractive for diurnal use, the coefficient of performance (COP) of the ice-maker needs to be substantially better than those currently available. Peak-shifting could come at the expense of total energy consumption or for some control strategies, cooling comfort.
