Abstract

A multigeneration system that produces energy, cooling, heating, hydrogen and freshwater has been analyzed in this research with a thermodynamic analysis. A solar parabolic trough collector (PTC) is the main source of energy for this system. AL2O3 Therminol VP1 nanofluid is the working fluid used in this solar collector. A steam Rankine cycle and an organic Rankine cycle for power generation, a double-effect absorption refrigeration system for cooling, a domestic water heater for hot water production, a proton exchange membrane (PEM) electrolyzer for hydrogen production and a reverse osmosis (RO) desalination unit for freshwater production are subsystems of this multigeneration system. A thermoelectric generator (TEG) unit instead of a condenser shall be used during the ORC cycle to produce additional power. The influences of different parameters and the nanoparticles on the performance of the proposed system are investigated. According to the outcomes, the energy and exergy efficiency of the system are 33.81 % and 23.59 %, respectively. The rate of hydrogen and freshwater production rates increase when the nanoparticle volume concentration and the solar radiation rise. Finally, it is found that the COP of the cooling system increases when the high desorber temperature goes up.
