ORC-Based Low-Temperature Geothermal Power Generation System

Abstract:

Based on the Organic Rankine Cycle，a low-temperature geothermal power generation were studied with R245fa as the working fluids ．Effects of hot water temperature,heat flux and heat-transfer temperature difference on overall heat-transfer coefficients 、net power and input heat were analyzed in detail．These results would provide a basis for the design of geothermal power generation．In addition，it would provide comparative data for the numerical simulation of heat ＆mass transfer study．
