heal.abstract	The aim of this research is to study and recommend optimal Rankine cycles using lsobutane (R600a) and R134a as working fluids for two geothermal binary power machines. The first one (ORC machine A) should be able to generate electricity from low temperature geothermal resources, with profitable operation down to 65 degrees C. The second one (ORC machine B) should be able to cogenerate both heat and power by heat recovery from the cooling water circuit, corresponding to geothermal fluids of 120-150 degrees C and cooling water supplying a district heating system at 60/80 degrees C. The main Rankine Cycle parameters and components are modelled, such as the shell and tube condenser and the geothermal plate heat exchanger. The objectives of the optimization are maximizing overall conversion efficiency and minimizing the cost of the plant, which is represented as minimizing the exchangers' surface. Through this research, a set of optimal solutions for ORC machines A and B are obtained that combine maximum plant's efficiency and minimum cost.	en
