Abstract

The efficiency of two cold supply systems (CSS) of a shop is compared: one operating on single stage cycle and the other with economizer. The comparison was done by the degree of the thermodynamic efficiency of refrigerating systems using the entropy and statistical method of the thermodynamic analysis. The dependences of the system operating parameters depending on time were used as the initial data. The dependences were obtained from the standard monitoring systems then averaged. The cycles corresponding to the operation of refrigerating systems compared and the formulae to calculate the minimal needed work to compensate the entropy generation in the elements of a refrigeration machine are cited. The results of the analysis showed that the degree of the thermodynamic efficiency of the system with economizer was higher than that of the system with single stage cycle. The use of a scroll compressor with economizer in the CSS saves the energy in comparison with the piston compressor; also the use of new generation scroll compressors with economizer will allow decreasing the capital costs of an aggregate. Keywords: entropy and statistical method of the thermodynamic analysis; singl stage refrigeration cycle; refrigeration cycle with economizer; cold supply system for a shop.
