【 摘 要 】

In order to effectively utilize geothermal resources at mid-low temperatures, an Organic Rankine cycle (ORC) system was used to establish a thermodynamic model. The working fluid of R245FA was analyzed and evaluated to determine the higher efficiency of the system. With evaporation temperature, geothermal temperature and cooling water temperature as key performance indicators, the system was employer and its efficiency influenced factors were studied. From the results we know that for the ORC system, when the geothermal water temperature reaches 373K and other input parameters are typical values, the total PPH of ORC system is 7.5.
