Abstract

The paper analyzes and proves the feasibility of improving the energy performance of low-temperature refrigeration machines operating on R744 using cascade design with R134a, R1234yf and R717 as refrigerants based on data the scientific study of two-stage schemes analysis. At present, it is given the existing environmental prohibitions and the growing interest in the creation of low-temperature refrigeration machines operating on carbon dioxide (R744) in two-stage and cascade schemes, the presented research supplements the scientific literature on justifying the use of each of them.
