Optimized Design of Total Energy Systems: The Rete Project

摘要

A design to optimize the utilization of primary energy sources, providing both electricity and heat, is described. A project plant will be located at Reggio Emilia (Italy). Several computer analyses were performed to provide climatic data, electric and heat demand diagrams, capacity dimensioning, plant operation simulation and economic analysis. This design methodology makes possible a total annual efficiency of 78% and fuel savings, as to a conventional system, of about 28%. Different processes are used in winter or summer, consisting of optimized combinations of diesel generators, auxiliary boilers, absortion chillers, and heat pumps, producing electricity with either refrigeration or heating.
