Abstract:
A system for ice bank storage and for providing multiple power sources and including;a primary fueled Brayton cycle turbine producing shaft power driving a base compressor for refrigeration and producing high heat energy exhaust gases;a heat recovery device for transferring high heat energy from said exhaust gases into a first fluid heat transfer medium flowing therethrough;a hot water generator for producing high temperature water in a closed circuit through said heat recovery device for the transfer of heat energy from said first fluid heat transfer medium to produce high temperature water;a steam generator for producing steam from said high temperature water supplied thereto and in said closed circuit with said hot water generator and heat recovery device for the transfer of heat energy from said first fluid heat transfer medium to produce said steam;a secondary Rankine cycle turbine operated by said steam from the steam generator and producing shaft power driving an ice chiller for circulation of a second heat transfer medium; andan ice bank structure in a closed circuit with said circulation of said second heat transfer medium from said ice chiller for ice storage.
