摘要

This study compares the results from the thermodynamic analysis at an Organic Rankine Cycle power plant,for first and second law efficiency,operating with 14 different working fluids.This plant—located in the town of Los Negritos,in the municipality of Villamar,in the State of Michoacán,Mexico—uses heat from a low-temperature geothermal source with the purpose of identifying the working fluids that are best suited for the operating conditions at hand.REFPROP v.8.0 software was used to collect the thermodynamic properties.Of all the thermodynamic parameters that were analyzed,the fluid that performed the best had an overall energy efficiency of 5.87%,an overall exergy efficiency of 43.07%,and a net output power of 13.04 kWe.
