Energy, exergy and exergo-environmental assessment of a novel solar powered Kalina cycle incorporated with micro-CCHP for poly-generation

In this study, a solar parabolic trough collector combined with a Kalina cycle, multi-stage flash desalination unit, a proton exchange membrane electrolyser for hydrogen production, and a micro-combined cooling, heating, and power system is presented. Systematic energy, exergy, and exergo-environmental evaluation are used to analyse the viability of the integrated systems as the most effective approach for performance assessment of integrated systems. The energy and exergy efficiencies of the overall system is observed to be 50.51% and 3.27% respectively. The rate of exergy destruction of each component and the overall cycle is determined where the parabolic trough collector is shown to have an exergy destruction rate of 234.4 kW, which is the highest among all the components. The performance of the proposed systems is also checked through a parametric study of the different key parameters.
