This study is directed to determine the maximun electric power extractable from geothermal low and medium enthalpy sources, through the use of Rankine's cycle with an organic fluid. The power plant is composed by a heat exchanger (preheater-boiler), turbine, electric generator, condenser and feeding pump. For an ensemble of five working fluids (R-11, R-12, R-114, R-600a, R-C318), the variation of maximun electric power is determined versus geothermal fluid temperature for various temperatures of condensation. At same time the optimal relation between the mass flow rate of working fluid and the mass flow rate of geothermal fluid and the mass flow rate of geothermal fluid is determined with those variables. This study also includes the variation of the efficiency of the installation. All the study is based upon geothermal water temperature between 80ºC and 140ºC. ABSTRACT.
