The article considers the results of comparing operational efficiency of carbon dioxide
transcritical cycles used in refrigeration systems for retail enterprises. We selected the
thermodynamic degree of perfection as the estimation criterion during comparison, and
analysed refrigeration systems using the statistical entropy method. As input data, we
selected parameters taken into account when designing refrigeration plants. We supply
circuit diagrams of the refrigeration systems considered and equations for calculating
the minimum work required to compensate for entropy production in the refrigerator
nodes. The analysis results made it possible to define ways of further optimising the re-
tail refrigeration system.
Keywords: statistical entropy analysis, thermodynamic analysis method, transcritical
cycle, carbon dioxide, carbonic acid gas, retail refrigeration systems
