Key Performance Indicators in Thermoacoustic Refrigerators Relative to Carnot Efficiency

Thermoacoustic refrigerators offer a promising alternative to conventional refrigeration technologies because their unique operating principles pose no harm to the environment. This study focuses on key performance indicators (KPIs) for thermoacoustic refrigerators, relative to their performance efficiency. The coefficient of performance (COP), the Carnot coefficient of performance (COPC) and the coefficient of performance relative to Carnot’s COP (COPR), crucial KPIs, are analyzed within the framework of Carnot efficiency (temperature difference). By comparing the analyzed performance metrics of a thermoacoustic refrigerator, such as COP and COPR, for a case study, the analysis provides insights into areas for improvement and optimization. The results highlight the potential and limitations of the temperature difference in current thermoacoustic technologies and suggest pathways for enhancing their efficiency to meet or exceed traditional refrigeration benchmarks.
