Résumé

The article describes the method of creating a cyclic-scheme decision of heat-using compressor refrigerating machine with carbon dioxide as the working substance, based on the thermodynamic analysis of the "method of cycles". The method of creating of the cyclic-scheme decision of the heat-using compressor machinery with carbon dioxide is based on the thermodynamic analysis of the "method of cycles". Through a phased build-up of irreversible in the cycle -sample (consistent «deterioration» of the ideal cycle) caused by the actual conditions of each element work in the composition of the refrigeration machine, reference cycles of valid machines were formed. Based on analysis, minimum elemental composition was defined, which provided real processes of heat transfer, expansion, compression in total with safe machine operation conditions with carbon dioxide. The estimation of the thermodynamic efficiency of cycles for real temperature machine operation modes was made.
