A multiobjective decision framework, which is developed to determine the optimal operational parameters and choose the best working fluids for the organic Rankine cycle taking thermodynamics, economy, and environment into consideration, is proposed. Net output work, electricity production cost (EPC), and equivalent carbon emission (ECE) are adopted as the thermodynamic, economic, or environmental indicators in the decision framework. Then, a sensitivity analysis is conducted to investigate the effect of criteria weights on working fluid selection and their priority variations. Finally, the decision results obtained from the Technique for Order by Similarity to Ideal Solution are compared with those obtained by another two kinds of decision making methods, namely, Multi-Factor Evaluation and Vector-Based Ranking method. Butane, R245fa, R1233zd(E), R245ca, and R123 are chosen as the working fluids. The result shows that R1233zd(E) is recognized as the most appropriate working fluid under the above three decision methods in this work. The corresponding net output work, EPC, and ECE are 7.76 kW, 6.690 × 10−2 $/kWh, and 2.075 × 10−2 kg CO2eq/kWh, respectively.A multiobjective decision framework, which is developed to determine the optimal operational parameters and choose the best working fluids for the organic Rankine cycle taking thermodynamics, economy, and environment into consideration, is proposed.

有机朗肯循环系统综合评价的多目标决策框架

提出了一个多目标决策框架，该框架被开发用于确定最佳操作参数并为有机朗肯循环选择最佳工作流体，同时考虑热力学、经济性和环境因素。净输出功、电力生产成本 (EPC) 和等效碳排放 (ECE) 被用作决策框架中的热力学、经济或环境指标。然后，进行敏感性分析以研究标准权重对工作流体选择及其优先级变化的影响。最后，将通过与理想解的相似度排序技术获得的决策结果与另外两种决策方法，即多因素评估和基于向量的排序方法获得的决策结果进行比较。丁烷、R245fa、R1233zd(E)、工作液选用R245ca、R123。结果表明，R1233zd(E)被认为是本文上述三种决策方法下最合适的工质。相应的净输出功、EPC 和 ECE 分别为 7.76 kW、6.690 × 10−2 $/kWh 和 2.075 × 10−2 kg CO2eq/kWh。开发用于确定最佳运行参数的多目标决策框架并从热力学、经济性和环境等方面考虑，为有机朗肯循环选择最佳工质。净输出功、电力生产成本 (EPC) 和等效碳排放 (ECE) 被用作决策框架中的热力学、经济或环境指标。然后，进行敏感性分析以研究标准权重对工作流体选择及其优先级变化的影响。最后，将通过与理想解的相似度排序技术获得的决策结果与另外两种决策方法，即多因素评估和基于向量的排序方法获得的决策结果进行比较。选择丁烷、R245fa、R1233zd(E)、R245ca 和 R123 作为工作流体。结果表明，R1233zd(E)被公认为在上述三个十... 多因素评估和基于向量的排序方法。选择丁烷、R245fa、R1233zd(E)、R245ca 和 R123 作为工作流体。结果表明，R1233zd(E)被公认为在上述三个十... 多因素评估和基于向量的排序方法。选择丁烷、R245fa、R1233zd(E)、R245ca 和 R123 作为工作流体。结果表明，R1233zd(E)被公认为在上述三个十...
