Abstract

The performance of a solar-powered Rankine cycle that combines absorption refrig-eration with solar thermal technology is examined in this communication. The re-search finds regions of irreversibility in the system and takes into account fluctuations in direct normal irradiance (DNI). In order to evaluate the cycle's performance at dif-ferent DNI levels ranging from 600 to 1050 W/m², the research does a thermody-namic analysis of the cycle. It also assessed the irreversibility of each cycle's distinct parts, which resulted in potential performance-enhancing actions. Furthermore, the central receiver contributes 31.37% irreversibility to the cycle's exergy distribution, the heliostat contributes 27.4%, and other components like the HRSG, steam turbine, and VARs contribute the rest amounts. Only 25.43% of the cycle's energy production is useable.
