Özet
In thy. work, the effects of utilizing Mg0-CuO, water nanofluid on the energetic t nd exergetic performances of a heat pipe evacut ted ;olar water collector have been analyzed experimentally. In this regard, two identical heat pipe evacuated sola, water collectors have been installed. In the first system, deionized water has been utilized. In the second collector, newly prepared nanofluid have been used and both collectors have been tested under the same climatic conditions at three flow rates containing 0.016, 0.033 and 0.050 kg/s. According to the experi mentally obtained outcomes, mean theimal efficiencies of the system using deionized water were obtained between 49.62 and 56.18 %. Also, average [hernial efficiencies of the system with Mg0-010/water as working fluid were obtained between 69.89 and 77.21 %. Average sustainability index values were attained in the range of 1.0271-1.0676 for both investigated systems. moreover, utilizing hybrid nanofluid in the system reduced the payback period between 25.14 and 27.74 %. The yearly ..7.02 savings for the system with and without nanofluid were attained between 0.307-0.343 and 0.217-0.251 ton/year, respectively. General outcomes of this study exhibited notable effects of utilizing Mg0-CuO/water on improving the thermal performance of the heat pipe evacuated solar water collector.
