Eco-design requisites for solar desaltification still augmented evacuated annular tube collectors with parabolic concentrator: an optimum-environ-economic viability

In this paper, an eco-design criterion for a novel solar desaltification setup (SDS) with evacuated annular tube collector (EATC) and a specific set of modified combination of parabolic concentrator has been examined for maximum performance with environmental and economic circumstances. This technique approaches to rectify the irregular utilization of EATC for optimum performance with environ-economic viabilities, which evidently satisfies the eco-design requirements and boosts the solar absorption capabilities uniformly along the periphery of vacuum tubes, and results improved thermo-syphon loom significantly more than in typical applications. The suggested unit is being refined and improved water temperature by 11.4% while keeping the basin lid and annular tubes at the same direction (30°). An incremental improvement in thermo-syphon circulation of 28.1% obtained through the present study. The average solar intensity of the respective clear day has been found as 401.8 kW and the overall energy and exergy efficiency on a daily basis are 50.8%, and 3.8%, correspondingly. At a minimal retail price of 0.07 $/l, and improved daily output by 12.3 kg per day than the typical SDS-EATC system taken for comparison into consideration are determined to be more satisfactory. 131.97 and 67.44 tons alleviates for $1318.36 and $673.77 from environmental generated money based on energy-exergy are there for CO2, respectfully. The setup cost is noticeably reduced by 9.15% to the comparative system, and its productivity is determined to be 940.8% (> 100%), and this indicates that the present system is highly viable and appreciable for the feasible adaptation with the positive environ-economic possibilities.
