To the issue of optimising the performance of a scroll compressor as part of a CO2 booster refrigerating machine in order to increase its efficiency

Objective . With the decreasing use of refrigerants with a high global warming potential, increasing efficiency refrigeration machines using natural working fluids is very urgent task. The CO2 booster refrigerant cycle may be optimal for fields commercial refrigeration, climate engineering and heat pumps, but needs to adapted regions hot climates. purpose study also systematize possible ways improve spiral technology, as guarantee machines. Method Such solutions have already been tested by transcritical through an ejector parallel compression. However, scroll compressor in good alternative these methods. This solution, little bit improves technical economic indexes refrigerating machine, most part reducing capital operational costs. When considering prospect improving system compressor, it necessary address issue performance optimisation. An this kind can referred system, at expense internal characteristics machine. Result. Thus, paper, conceptual approach considered solve problem based on analysis interconnection main energy-intensive element Conclusion Development model, allows identify influence various factors operation build adequate mathematical choose or develop calculation
