摘要: This paper presents the new ternary non-azeotropic mixture of R32/R125/R161 as an alternative refrigerant to R407C. The physical properties are similar those R407C, and it is environmental friendly, that is, has zero ozone-depletion potentials (ODP) lower global warming (GWP) than Theoretical cycle performances R407C calculated analyzed firstly. Based on theoretical study, experimental tests performed a vapor-compression refrigeration system with rotor compressor which was originally designed for (without any modifications components R407C). Experimental results under different working conditions indicate pressure ratio power consumption its refrigerating capacity coefficient performance (COP) superior respectively, discharge temperature slightly higher Therefore, could be considered promising
