Assessment of the Impact of using Zeotropic Mixture on the Thermodynamic Performance of Organic Rankine Cycle Integrated Vapor Compression Refrigeration System

Ashwni, Ahmad Faizan Sherwani

[ABSTRACT ]

The present paper assesses the impact of the zeotropic mixture such as R245fa/ R152a, butane/R152a, and R245fa / butane on the performance of an organic Rankine cycle (ORC) - Vapor compression refrigeration (VCR) system. In this work, the system performance indicators like the coefficient of performance (COP) of the VCR subsystem and ORC-VCR system, and the exergetic efficiency of the ORC-VCR system have been evaluated. The results from the analysis indicate that the zeotropic mixture of R245fa/butane exhibits a maximum COP of 0.583 for the system and COP of 5.02 for the VCR subsystem for mixture ratios up to 0.46.
