Novel design for tri-generation cycle with Parabolic Trough Collector: An exergy-economic analysis

چکیده مقاله

RRECTE c Rankin cycle condenser as the energy source of the absorption refrigeration cycle. A fluids such as n-octane, n-heptane, n-pentane, and n-hexane on the operation of the wh gated. The validation of the results has been carried out which showed acceptable agre curacy of the proposed model. The power coeffcient and exergy factor of the cycle 72 and 23.83%, respectively. Furthermore, the highest exergy destruction of the pro occurs in the steam generator, the generator of the absorption refrigeration cycle, an e cycle by 14742 MW, 3974 MW and 3374 MW with the exergy destruction percentag espectively. In the economic aspect of the proposed system, the highest cost is for th tion refrigerator system with 69.71 dollars per hour and the second and third highes e turbine with 32.4 and 30.33 dollars per hour which have 41%, 19% and 18% of ed system, respectively. Also, the results show that the most costs of waste are for the HX heat exchanger which waste 6.639, 5.586 and 4.22 dollars per hour with 34%, 29 ost of waste, respectively. Moreover, it can be seen that by increasing the temperature o 00° to 500°, the frst-law effciency decreases from 37.6% to 28.6%, the second-law 0.15% to 17.29% and the total cost decreases from 4.78 to 4.77 dollars per Gigajoul
