Analisa Effisiensi Pada Fluida Kerja Berdasarkan Variasi Temperatur Masuk Turbin Pada Pengembangan Organic Rankine Cycle

Abstract

In this paper present the comparisson condition at turbin inlet for R134a as working fluids for use in the development of Organic Rankine Cycle. The variation of temperature are : 80oC, 85oC and 90oC. The efficiency analysis in the development of ORC based on Thermodynamic analysis. The method to analysis working fluids, in this paper use Cycle Tempo and the properties of working fluid use Refprop. The result of this analysis are : For R 134a with inlet turbine temperature 80oC have efficiency 7,94%, For R 134a wih inlet turbine temperatur 85oC have efficiency 8,11%, and the last for R134a with inlet turbine temperature 90oC have efficiency 8,25%. Based on this result, the best inlet turbine temperature for the development of ORC with R134a as working fluide is 90oC
