In this study, a feasibility analysis of a solar‐assisted transcritical Rankine cycle working with carbon dioxide (CO₂) is performed for Isparta, Turkey, in comparison with Kyoto, Japan, conditions. For the analyses, the characteristics of the system are adapted from the actual experimental research conducted at Doshisha University, Kyoto, Japan. In order to evaluate the performance of the CO₂‐based integrated system, a mathematical model is established for the evacuated solar collectors. Energy and exergy analyses are carried out using the solar energy data of both cities. According to the simulation results, the average turbine power capacities are determined as 0.415 and 0.396 kW, while the average heat recovery capacities are calculated as 2.10 and 1.89 kW for Isparta and Kyoto, respectively. The yearly electricity generation for Isparta conditions is found to be about 40% higher than the Kyoto conditions with 1138.09 kWh. The results of second law analyses are showed that the highest exergy destruction rate occurs in August for Isparta conditions with 8.18 kW due to the higher solar radiation rates. From the results, it appears that the CO₂‐based next‐generation solar‐assisted power and heat generation system can be established and utilized in Isparta more effectively. The future research should, therefore, concentrate on moving the actual experimental setup to Isparta for field test experiments. © 2019 Society of Chemical Industry and John Wiley & Sons, Ltd.

基于CO2的太阳能辅助朗肯循环的可行性研究：土耳其伊斯帕塔的比较案例研究

在这项研究中，与日本京都的条件相比，在土耳其伊斯巴达进行了使用二氧化碳（CO ₂）的太阳辅助跨临界朗肯循环的可行性分析。为了进行分析，系统的特性是根据在日本京都的同志社大学进行的实际实验研究改编而成的。为了评估CO ₂的性能基于集成系统，为抽空的太阳能集热器建立了数学模型。使用两个城市的太阳能数据进行能源和火用分析。根据仿真结果，确定的平均涡轮功率为0.415和0.396 kW，而Isparta和Kyoto的平均热回收容量分别为2.10和1.89 kW。发现伊斯巴达条件下的年发电量比京都府条件下的1138.09 kWh高约40％。第二定律分析的结果表明，由于较高的太阳辐射率，八月份伊斯巴达条件下的最高火用破坏率发生在8.18 kW。从结果看来，CO ₂可以在Isparta中更有效地建立和利用基于下一代的太阳能辅助发电和供热系统。因此，未来的研究应集中在将实际实验装置移至Isparta进行现场测试实验。©2019年化学工业协会和John Wiley＆Sons，Ltd.
