Abstract: |
This paper presents a novel solar and geothermal fuelled trigeneration system intergrated with flat plate solar collectors. The desired system is based on ejector refrigeration and organic Rankine cycle. Two types of fluids namely R134a and R423A as the pure and zeotropic working fluids, respectively are seperately used in desired system. Al2O3 and CuO nanoparticles suspended in the pure water is applied inside of the flat plate collectors. Thermodynamic and parametric study indicate that inceasing the CuO nanoparticles in base fluid has a highly positive effect on the daily energy and exergy efficiencies for both working fluids relative to the Al2O3. Furethermore, CuO nanoparticles inceasing lead to the high increment in the daily energy and exergy efficiencies by about 1.65% and 9.79%, respectively for R423A as a zeotropic working fluid relate to their base point in comparison with R134a pure working fluid. |
