An exergetic analysis of an experimental refrigeration system using R134a was performed to identify and quantify the exergetic losses.

The research is based on analyzing the influence of six operational and controllable parameters of the experimental setup.

The major exergy destruction rate is located at condenser followed by the compressor.

The contribution of the compressor to the overall irreversibility is the most relevant.

A maximization of exergetic efficiency is implemented to determine the best combination of controllable parameters.
