Energy and exergy analysis of an enhanced solar CCHP system with a collector embedded by porous media and nano fluid

The low efficiency of Collectors that absorb energy can be mentioned as one the drawbacks in solar cogeneration cycles. In present study, systems have been improved by adding porous media and Nanofluid to collectors. One advantage using nanomaterials is more while surface area reduced. this first, collectors are enhanced 90% porosity copper combined cooling, heating power (SCCHP). Second, different percentages CuO Al2O3 nano-fluids added a flat plate parabolic enhance thermal properties. Simulations performed modes (simple collectors, simple with media, density nanofluids). A case study investigated for warm dry regions mean radiation Ib = 820 w / m2 Iran. maximum exergy efficiencies 60.12% 18.84%, respectively, related nanofluids. Adding increases an average 14.4% collector 8.08% efficiency.
