Abstract EN
The refrigerant R134a widely used in refrigerating and air conditioning units .It has zero ozone depilation potential factor (ODP) but have 1300 global warming potential (GWP) and their interaction with heat radiation.
It is necessary to minimize the global warming, by changing R134a with the ones that are not depleting the ozone layer and very little in Global Warming Potential (GWP).
In this paper, a new azeotropic refrigerant mixture of three refrigerants named R134a, R290 and R600a with four different.
mixing ratio of mass are used as an alternatives refrigerant to.R134a..
The theoretical model show that, all new refrigerant mixtures give higher refrigerating effect than that of R134a.
Meanwhile experimental results revealed that the obtained COP by the new mixtures is less than that of R134a, and the most suitable refrigerant that can be used instead of R134a was Mix2.The COP of Mix2 is 8 % less than that of R134a at 24 ℃ room temperature.
