Performance analysis of N identical PVT-CPC collectors with an active single slope solar distiller and helically coiled heat exchanger using CuO nanoparticles
This paper presents performance analyses based on temperatures, thermal energy (overall), thermal exergy (overall), electrical exergy, and yield of the systems that have been investigated. In the present study, an analytical expression of N identical partly covered photovoltaic compound parabolic concentrator collectors connected in series (N-PVT-CPC-SS-HE) with an active single slope solar distiller unit and helically coiled heat exchanger has been found. The performance analyses of the proposed system have been executed for 0.25% concentration of CuO nanoparticles for collectors (N = 4), and fluid-flow rate 0.02 kg/s in 280 kg mass of basin fluid. The system's performance is compared with a previous system of N identical partly covered photovoltaic flat plate collectors connected in series (N-PVT-FPC-DS-HE) with an active double slope solar distiller unit and helically coiled heat exchanger. The thermal energy is 112,109.1 kWh, thermal exergy 312.07 kWh, and yield 3,615.05 kg annually. It is found that daily enhancement in thermal energy of the proposed system with CuO nanoparticles compared with the previous system with various nanofluids CuO, Al2O3, TiO2, and water is found to be 16.75%, 51.13%, 61.82%, and 80.67% more significant correspondingly. The enhancement in yield of the proposed system is obtained for CuO nanoparticles greater than the previous system with CuO by 11.19%, Al2O3 17.2%, TiO2 26.25%, and water 32.17%. The electrical exergy is almost the same as the previous system. HIGHLIGHTS Analyzed single slope N-PVT-CPC-HE system.; Overall thermal energy has been computed.; Overall thermal exergy has been calculated.; Annual yield for proposed system has been evaluated.; CuO nanoparticles.;
