This paper describes optimal sizing of ice storage and chiller system through parametric simulation for a commercial office building with peak cooling load of 600 tons. As an optimality criterion, the minimization of the annualized capital cost and fuel exergy costs on the basis of thermoeconomic analysis was chosen. This paper considers encapsulated ice storage system in chiller-downstream arrangement with chiller-priority control and storage-priority control strategies. Minimal required chiller sizes of the system for each control strategy are determined with storage fraction from 40% to 60%. The design condition, which has minimum cost, lies on the curve of the set of required chiller size and storage fraction. The optimal sizing is defined in this paper as the choice of size of chiller and storage tank, which leads to minimization of the annualized cost per exergy unit of product for the system.
