有机朗肯循环（ORCs）是一种将废热转化为电能的成熟技术。尽管存在几种商业应用，但仍有相当大的热经济优化潜力。基于此，本文提出了一种基于多目标优化方案并结合后处理阶段财务评价的ORC系统优化设计框架。建议的方法提供了快速评估几种经济方案的灵活性，而不需要了解复杂的设计过程。这种优化和解释结果的新方法应用于一个废热回收案例。利用所提出的优化策略对跨临界ORC和亚临界ORC进行了研究和比较。
Organic Rankine cycles (ORCs) are an established technology to convert waste heat to electricity. Although several commercial implementations exist, there is still considerable potential for thermo-economic optimization. As such, a novel framework for designing optimized ORC systems is proposed based on a multi-objective optimization scheme in combination with financial appraisal in a post-processing step. The suggested methodology provides the flexibility to quickly assess several economic scenarios and this without the need of knowing the complex design procedure. This novel way of optimizing and interpreting results is applied to a waste heat recovery case. Both the transcritical ORC and subcritical ORC are investigated and compared using the suggested optimization strategy.
