Abstract In this study, a new parabolic solar collector integrated combined power and refrigeration system with the thermoelectric generator (CPR-PTSC with TEG) was proposed. The suggested system was evaluated through energy, exergy, and exergo-economic analyses, and the effect of the TEG on the power generation performance was investigated. The influences of significant parameters such as pressure ratio of supercritical Brayton cycle (BC), length of parabolic solar collector, turbine inlet pressure (TIP) of transcritical Rankine cycle (RC), compressor discharge pressure (CDP) of vapor compression refrigeration cycle (VCRC) were determined. According to the results, it was found that the integration of the thermoelectric units to the system improved the exergy performance of the system with an exergy destruction rate of 803.4 kW, where it was calculated as 821.38 kW for the system without TEG. The result of parametric analyses represented that the various system parameters have the same effects on the performance of both CPR-PTSC with and without TEG. Furthermore, with the exergo-economic analysis of CPR-PTSC with TEG, the cost of generated power for TEG I and II were determined to be 0.6311 US$/h and 2.202 US$/h, respectively, and the cooling costs were calculated as 0.994 US$/h and 0.7462 US$/kWh.

使用 3E 分析提出一种新的抛物面太阳能集热器辅助电力制冷系统与热电发电机集成：能源、火用和火用经济

摘要 在这项研究中，提出了一种带有热电发电机的新型抛物面太阳能集热器联合动力和制冷系统（CPR-PTSC with TEG）。通过能量、火用和火用经济分析对建议的系统进行了评估，并研究了 TEG 对发电性能的影响。超临界布雷顿循环 (BC) 压比、抛物线太阳能集热器长度、跨临界兰金循环 (RC) 涡轮入口压力 (TIP)、蒸汽压缩制冷循环 (VCRC) 压缩机排气压力 (CDP) 等重要参数的影响) 确定。根据结果​​发现，热电单元与系统的集成提高了系统的火用性能，火用破坏率为803.4 kW，对于没有 TEG 的系统，计算为 821.38 kW。参数分析的结果表明，各种系统参数对使用和不使用 TEG 的 CPR-PTSC 的性能都有相同的影响。此外，通过 TEG 的 CPR-PTSC 运行经济分析，TEG I 和 II 的发电成本分别确定为 0.6311 美元/小时和 2.202 美元/小时，冷却成本计算为0.994 美元/小时和 0.7462 美元/千瓦时。
