Exergy Analysis and Performance Evaluation of a Vapor Compression Refrigeration System Using R-134a, R-600a, and R-125
This paper presents an exergy analysis of a vapor compression refrigeration system where total exergy loss, exergetic efficiency, coefficient of performance, and compressor power input were calculated to assess system performance. The analysis was initially validated using a MATLAB model with refrigerants R-134a, R-12, and R-22 from existing literature. In the study that followed, refrigerants R-134a, R-600a, and R-125 were tested under various evaporator and condenser temperatures while maintaining one of the parameter constants in each case. The results demonstrate clear trends in exergy losses within key system components, allowing for a detailed understanding of how temperature changes affect system efficiency and performance while also providing insights on a comparative analysis of refrigerants used to improve system optimization, aiding in the design of more efficient refrigeration systems.
期刊介绍:
The International Journal of Refrigeration is published for the International Institute of Refrigeration (IIR) by Elsevier. It is essential reading for all those wishing to keep abreast of research and industrial news in refrigeration, air conditioning and associated fields. This is particularly important in these times of rapid introduction of alternative refrigerants and the emergence of new technology. The journal has published special issues on alternative refrigerants and novel topics in the field of boiling, condensation, heat pumps, food refrigeration, carbon dioxide, ammonia, hydrocarbons, magnetic refrigeration at room temperature, sorptive cooling, phase change materials and slurries, ejector technology, compressors, and solar cooling.
As well as original research papers the International Journal of Refrigeration also includes review articles, papers presented at IIR conferences, short reports and letters describing preliminary results and experimental details, and letters to the Editor on recent areas of discussion and controversy. Other features include forthcoming events, conference reports and book reviews.
Papers are published in either English or French with the IIR news section in both languages.
