Abstract
This paper presents an analysis of basic organic Rankine cycle (ORC) using five type dry fluids: R123, Iso-butane (R600a), R114, Rc318 and Toluene with boiling points ranging from -11.7℃ to 110.6℃, to convert waste energy to power from low-grade heat sources. These organic fluids are analyzed and compared, in order to determine with which of them the best performance can be obtained. The evaluation will be performed using a combined first and second law analysis by varying certain system operating parameters at saturation conditions. Results from these analysis show that the higher system thermal efficiency was obtained with the working fluids toluene and R123 compared with the others working fluids. In addition, the fluid that shows the best thermal efficiency is the one that has highest boiling point.
