Abstract

Nowadays, the development of energy systems based on efficient renewable energy has been the focus of researchers to overcome environmental issues. This study presents a multi-generation system with solid oxide fuel cell, Brayton modular helium, reverse osmosis desalination, Stirling engine and cascaded absorption-condensation refrigeration. In this way, the system's functioning was examined from the perspective of the first law of thermodynamics. Then the second law of thermodynamics was used to determine the exergy efficiency of each subsystem and the amount of exergy destruction. The proposed cycle was subjected to an exergoeconomic analysis. At the end, in order to understand the behavior of the performance criteria of the system with the design parameters, a comprehensive parametric study has been conducted. The results show that the proposed cogeneration system can produce 9.705 MW of net power, 8.45 kg/s of fresh water and 68.79kW of cooling. Also, the energy and exergy efficiency of the whole production system at the same time have been calculated as 55.02 and 49.82%, respectively. Also, the product's CO2 emission rate and component's investment cost rate are 17.59 kg/MWh and 105.7 $/kWh, respectively
