Abstract In this article, three different modes of a novel integrated system would be evaluated by the application of high temperature Thermal Energy Storage (TES) to produce electricity, cooling, and freshwater. Freshwater is produced using the reverse osmosis (RO) desalination unit while Absorption Refrigeration Cycle (ARC) provides cooling. In this system, a high temperature Phase Change Material (PCM) is utilized to make the system working continuously even at nights. The output heat of gas turbine (GT) is also recovered utilizing the Organic Rankine Cycle (ORC). According to exergoeconomic analysis, the efficiencies, exergy destructions and product cost rates are computed. The multi-objective optimization has also been performed considering six different ORC working fluids and the changes in the direct normal irradiation of a city in Iran. In the trigeneration condition, the optimum values of the GT’s compressor pressure ratio and ORC’s turbine inlet pressure were obtained 9.06 and 3300 kPa, respectively. The exergy efficiency of the suggested system at the optimal condition is computed to be 14.40%, while that of energy is 40.52% with the total product cost rate of 30.524 $/GJ. The produced cooling capacity of the absorption system is also 1.62 MW whereas the output amount of freshwater and electricity for the users are about 5209.5 m3/day and 2.42 MW, respectively. The Levelized Cost of Electricity (LCoE) is also calculated to be 0.2341 $/kWh, which shows promising economic performance.

用于电力、冷却和淡水生产的具有 PCM 的连续太阳能驱动系统的多目标优化和火力经济分析

摘要 在本文中，将通过应用高温热能储存 (TES) 来发电、冷却和淡水来评估新型集成系统的三种不同模式。淡水是使用反渗透 (RO) 脱盐装置生产的，而吸收式制冷循环 (ARC) 则提供冷却。在该系统中，使用高温相变材料 (PCM) 使系统即使在夜间也能连续工作。燃气轮机 (GT) 的输出热量也利用有机朗肯循环 (ORC) 进行回收。根据火用经济学分析，计算效率、火用破坏和产品成本率。还考虑了六种不同的 ORC 工作流体和伊朗城市直接法向辐射的变化，进行了多目标优化。在三联产工况下，GT 的压气比和 ORC 的涡轮进口压力的最佳值分别为 9.06 和 3300 kPa。建议系统在最佳条件下的火用效率计算为 14.40%，而能量效率为 40.52%，总产品成本率为 30.524 $/GJ。吸收系统产生的制冷量也为1.62 MW，而用户的淡水和电力输出量分别约为5209.5 m3/天和2.42 MW。电力平准化成本 (LCoE) 也计算为 0.2341 美元/千瓦时，显示出良好的经济表现。建议系统在最佳条件下的火用效率计算为 14.40%，而能量效率为 40.52%，总产品成本率为 30.524 $/GJ。吸收系统产生的制冷量也为1.62 MW，而用户的淡水和电力输出量分别约为5209.5 m3/天和2.42 MW。电力平准化成本 (LCoE) 也计算为 0.2341 美元/千瓦时，显示出良好的经济表现。建议系统在最佳条件下的火用效率计算为 14.40%，而能源效率为 40.52%，总产品成本率为 30.524 $/GJ。吸收系统产生的制冷量也为1.62 MW，而用户的淡水和电力输出量分别约为5209.5 m3/天和2.42 MW。电力平准化成本 (LCoE) 也计算为 0.2341 美元/千瓦时，显示出良好的经济表现。
