Abstract

In this study, a new hybrid system for producing fresh water from seawater using solar energy is proposed. It suggests a modified and optimized approach to reduce the reliance on fossil fuels and decrease pollutants by also harnessing solar energy. The system includes flat-plate solar collectors, a multi-effect distillation through thermal vapor compression (MED-TVC) desalination unit, a pump, and a boiler. The flow rate of the produced fresh water and the specific cost of generating fresh water volume were considered objective functions and the system was optimized using as evolutionary algorithm. The algorithm was employed to determine 12 design variables. Series, parallel, and series-parallel configurations were examined as layouts for flat plate collectors. The results indicated that the series-parallel arrangement was the most effective layout for the collectors. The modeling was carried out for the city of Bandar Abbas in Hormozgan Province, Iran. The production of fresh water in series-parallel mode has increased by 12.15 % and 27.83 %, respectively, compared to the parallel and series configurations at the ideal point. An assessment of the results suggests that choosing the design point within the flow rate range of 4.19 L/s to 4.65 L/s is preferable.

新型混合海水淡化厂太阳能集热器网络的优化设计

本研究提出了一种利用太阳能从海水中生产淡水的新型混合系统。它提出了一种改进和优化的方法，通过同时利用太阳能来减少对化石燃料的依赖和污染物。该系统包括平板太阳能集热器、热蒸汽压缩多效蒸馏（MED-TVC）海水淡化装置、泵和锅炉。生产淡水的流量和产生淡水量的具体成本被视为目标函数，并使用进化算法对系统进行优化。该算法用于确定 12 个设计变量。研究了平板集热器的串联、并联和串并联配置布局。结果表明，串并联布局是最有效的集热器布局。建模工作是在伊朗霍尔木兹甘省的阿巴斯港进行的。与理想点的并联和串联配置相比，串联-并联模式的淡水产量分别增加了 12.15 % 和 27.83 %。对结果的评估表明，最好在 4.19 升/秒至 4.65 升/秒的流速范围内选择设计点。
