Summary

In this paper, the mixture of R161/R134a (0.6/0.4 in mass fraction), named ‘M5’, is proposed as a substitution of R134a used in automotive air conditioning systems. The theoretical and experimental cycle performances for M5 and R134a were conducted at the condensation temperature from 50°C-65°C, evaporation temperature from -5 °C–10°C. Theoretical results show that COP of M5 is very close to that of R134a, the specific refrigeration capacity and volumetric refrigeration capacity of M5 are much higher than those of R134a. Experimental results show that COP of M5 is a bit higher than that of R134a, the refrigeration capacity and compressor power of M5 are about 32% and 30% higher than those of R134a, respectively, the compressor discharge temperature and pressure ratio of M5 are about 15% higher and 10.9% lower than those of R134a, respectively. Considering the good performance and compatibility with the existing system, M5 is a potential alternative refrigerant for R134a.
