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 refrigeration cycles analysis for industrial application. The ESMA was applied to investigate main refrigeration cycles, which are used for industrial application – two stage cycles with full intermediate cooling and without full intermediate cooling. The description of calculation method was given. The investigation was made for both nature refrigerants (propane, ammonia, CO2) and HFC (R507A). 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) as an only efficiency criterion.
