我们提出了一种新型的环保系统，称为“有机朗肯循环”（ORC），其中利用了低品位的热源。该系统结合了循环热虹吸和涡轮系统。本研究使用的工质是一种有机物，它具有低沸点和低潜热，可以使用低品位热源。为了估计ORC的最佳运行条件，建立了ORC的数值模拟模型。本研究还制作了实验装置。数值模拟表明，HCFC-123的涡轮功率高于常规工质水，且涡轮进口饱和蒸汽处的工况性能最佳。实验结果表明，HCFC-123显著提高了循环性能。此外，本研究试制的水轮机性能良好。
We propose a new type of environmentally friendly system called the “Organic Rankine Cycle” (ORC) in which low-grade heat sources are utilized. This system combines a circulated thermosyphon with a turbine system. The working fluid used in this study is an organic substance which has a low boiling point and a low latent heat for using low-grade heat sources. A numerical simulation model of the ORC is made in order to estimate its optimum operating conditions. An experimental apparatus is also made in this study. From the numerical simulation, it is suggested that HCFC-123 gives higher turbine power than water which is a conventional working fluid, and operating conditions where saturated vapor at the turbine inlet would give the best performance. From the experimental results, HCFC-123 improves the cycle performance drastically. In addition, the turbine made for trial use in this study gives good performance.
