Abstract
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.
