AB - The performance of a new mixed refrigerant R1234yf/R13I1 with a mass ratio of  90/10 under basic refrigeration cycle and refrigeration cycle with internal  heat exchanger is calculated in comparison with the performance of R134a  under basic refrigeration cycle at different condensation temperature and  evaporation temperature. The results show that R1234yf/R13I1 is virtually  non-flammable with global warming potential of less than 4. Under basic  refrigeration cycle, the compressor power consumption, cooling capacity and  COP of R1234yf/R13I1 are lower than these of R134a by about 4.5%, 9.5%, and  7.5%, respectively. Under refrigeration cycle with internal heat exchanger,  the compressor power consumption, cooling capacity, and COP of  R1234yf/R13I1 are lower than these of R134a by about 2%, 4.5%, and 3%,  respectively. The R1234yf/R13I1 is a beneficial refrigerant of replacing  R134a in vapor compression system.
