Tech-en-econ-energy-exergy-matrix (T4EM) observations of evacuated solar tube collector augmented solar desaltification unit: A modified design loom

Abstract

In the present study, a sophisticated novel design of solar desaltification unit (SDU) with evacuated solar tube collector integrated unique combination of modified compound parabolic concentrators (MCPC) has been analyzed Tech-En-Econ-Energy-Exergy-Matrix (T4EM) observations under the specific meteorological conditions of New Delhi, India. The proposed model undergoes a novel design having a boosting performance due to its unique design considerations (i.e. utilization of partially diffused solar radiations through segmented parabolic collector towards the identically exposed EATC) and associated arrangement of oriented compound parabolic concentrators (OCPC) and cusp compound parabolic concentrators (CCPC) (accumulatively the MCPC) integrated to the South faced solar desaltification unit. The current approach emphasizes the EATC utility and performance by utilizing 200% of solar radiation uniformly through its periphery and enhancing the thermo siphons working principle appreciably. Further, the utilization of optimum water mass and number of EATCs enables the proposed system comparatively better in performance than of the single slope SDU and double slope-SDU or with the nearby combinations in terms of yield, economy (environ, energy, exergy), energy matrices, design, system efficiency, life cycle conversion efficiency, carbon mitigate, emission, and credits, yield cost per liter, etc. The explored results are well compared and validated with the existing researches and found appreciable increment in the performance of the proposed system in terms of the aforementioned categories. The entire work has been sensibly concluded with the positive recommendations ahead.
