Abstract

A new integrated solar energy system is developed and designed to meet the demands of electricity, cooling and heating for a small city of 5000 homes. The system utilizes concentrated solar power, and photovoltaic thermal, integrated with an organic Rankine system and an absorption refrigeration system to provide district cooling and district heating. The overall exergy and energy efficiencies of the system are found to be 49.2% and 53.4% respectively. The highest exergy destruction rate stems from the CSP farm and accounts for 46% of the total system exergy destruction. The system’s life cycle analysis is conducted, and its results show electricity production from the photovoltaic system as well as the organic Rankine system account for the highest impact potential throughout all categories, including global warming and acidification potential.
