This research paper deals with the experimental investigation of solar energy-based water purifier (SEBWP) of single-slope type by incorporating N similar evacuated tubular collectors (ETCs) having series connection. Experimental investigation has been done for a year from August 2018 to July 2019. MATLAB has been used for evaluating performance parameters of the system followed by the validation of these results with their experimental values. A fair agreement has been found between theoretical and experimental values. Values of correlation coefficients for condensing glass temperature, water temperature, and water yield have been found to be 0.9932, 0.9928, and 0.9951 respectively. Further, energy metrics, productivity, cost of producing 1 kg of fresh water, and exergoeconomic and enviroeconomic parameters have been evaluated. Values of energy payback time, per kilogram cost of producing fresh water and exergy loss per unit Rs. have been evaluated to be 1.72 years, Rs. 0.95/kg, and 0.128 kWh/Rs. respectively.
本研究论文探讨了单坡型太阳能水净化装置（SEBWP）的实验研究，该装置采用串联连接的 N 个类似的真空管式集热器（ETCs）。实验研究从 2018 年 8 月至 2019 年 7 月进行了一年。使用 MATLAB 评估系统的性能参数，并用实验值验证这些结果。理论值和实验值之间存在良好的一致性。凝结玻璃温度、水温、产水量的相关系数分别为 0.9932、0.9928 和 0.9951。此外，还评估了能量指标、生产力、生产 1 公斤淡水的成本以及火用经济和环境经济参数。能量回收期、每公斤生产淡水的成本和每卢比的单位 exergy 损失分别评估为 1.72 年、0.95 卢比/公斤和 0.128 千瓦时/卢比。
