Exergy method for analysing and optimising refrigeration processes

A process is thermodynamically ideal if it leads to no exergy loss. In practice, the divergence from this ideal is indicated by the exergy loss, which provides a measure of the effectiveness of the technical process considered. In the present paper, the exergy losses occurring in a single-stage, vapour-compression refrigeration plant and associated cold-storage room are assessed. Prospective actions aimed at improving the refrigeration process are discussed.
