碩士 === 國立臺北科技大學 === 製造科技研究所 === 106 === Organic Rankine Cycle (ORC), both past and present in the world, is quite limited in experimental research. In particular, the ORC system, which has a scale of less than 1kWe, is very rare. Due to the smaller ORC system, due to the smaller components and fittings of the equipment, the actual assembly has higher measurement errors. Moreover, the existing equipment, such as the use of pump specifications are not suitable for micro-ORC system, so in the selection and calibration is an important issue. Therefore, the current research papers show that micro-ORC system in fact the size of the whole are quite large, and the system efficiency is quite low. The purpose of this study is to challenge the experiment and optimization design of micro-ORC system. The ORC system is designed by theoretical calculation, experimental planning, design and testing of different operating conditions and compact pipeline design. In addition, the micro-ORC system has a very worthwhile concern in practical testing. That is, it can test the use of important components such as heat exchangers and expanders. The results obtained are valid for the larger power generation ORC systems Words can be used as an important reference. In this study, the organic fluid R-245fa was chosen as the working fluid in the closed loop. The effect of different expander volume expanders on the whole system was explored by using scroll-type expanders with different inspiratory volumes. In addition, a series of experimental studies are also conducted on the flow of different simulated heat sources and the flow of cooling water.
