Abstract
In this chapter, a solar-based multigeneration system is examined in terms of heating, cooling and electricity generation capacity, as well as energy and exergy efficiencies. Through this sun-powered system, multiple useful outputs are obtained and utilized for a sustainable community. Moreover, two molten storage tanks with higher and lower temperatures are used to minimize energy imbalances in the system. While the energy required for the system is supplied from the solar tower, electricity and heat are produced to the community with the Brayton-Rankine combine cycle. Furthermore, the desired cooling is obtained with the absorption refrigeration system powered by the rejected heat from the Brayton cycle. The overall energy and exergy efficiencies of the system are found to be 69.33% and 41.81%, respectively.
