Numerical analysis of a scroll expander driven by various refrigerants for ORC applications
https://orcid.org/http://orcid.org/0000-0002-6566-7530
This numerical investigation focuses on the prediction of scroll type expander’s performance with different working fluids in low temperature organic Rankine cycle system. The scroll type expander under study is derived from a scroll compressor ZR28KM-PFZ-582 and experimentally tested with compressed air as a working fluid. Numerical model validation is done with CFD simulation. This analysis is performed in two stages. In the first stage, performance of scroll-type expander is evaluated with different working fluids by integrating it into ORC cycle. In the second stage, the working fluids are compared at different speeds and temperature to find the suitable working fluid for various pressure applications. The working fluids selected for this analysis are R134a, R152a, R142b, R717, R1270, and Propane. In the present analysis, the volumetric ratio is fixed to value 3.5. The outlet temperature is key factor in analyzing the expansion losses and for determining the volumetric ratio of the expander. From the numerical analysis, it is identified that performance of scroll type expander mainly varies with the density of the working fluid.
