Thermal and economic evaluation of an ice thermal storage system

Gas turbine power output and efficiency, decrease with increasing the atmospheric temperature. This may be compensated by using compressor inlet cooling systems in forms of evaporative cooling, vapor compression and/or absorption, and thermal storage systems (TES). Thermal and economic evaluation of a latent TES system using ice storage is studied in this paper. The objective function is the capital and operational costs of the gas turbine plant with a vapor compression refrigeration system for producing ice in a storage tank. The system design parameters were obtained using the search method optimization technique.
