摘要

Results of analysis of thermodynamic cycle efficiency with consideration of nonisothermal nature of phase transition indicate that when using the mixture of R32/R152a (30/70%) in the vapor compression heat pumps, the coefficient of performance is up to 4% higher in comparison with R32/R134a (30/70%). The study shows that in cycles with two-stage compression the coefficient of performance increases by 6.5% as compared to the single-stage process. The value of exergic efficiency of the single-stage cycle is equal to 0.47 for zeotropic mixture of R32/R152a (30/70%), and it is equal to 0.45 for the R32/R134a (30/70%) mixture. Data obtained for the zeotropic mixtures are as effective as those obtained for refrigerant R134a.
