Résumé

The entropic and statistical method of the analysis (ESMA) allows calculating losses in different refrigeration plant components and comparing them to define the elements that need measures to increase their operation efficiency. The paper presents CO2 refrigeration cycles analysis for application in retail. The ESMA was applied to investigate four CO2 refrigerating systems and define elements for further optimization. The description of calculation method was given. The comparison with refrigeration systems using R404A as refrigerant was made. The degree of thermodynamic efficiency was calculated. This result couldn’t be achieved using a traditional method of comparison refrigeration systems by using a coefficient of performance (COP) or seasonal efficiency as an only efficiency criterion.
