Performance Study Of Ecofriendly Refrigerant Mixture As An Alternative To R134a In A Household Refrigerator

Abstract

R134a is a popular, environmentally friendly refrigerant that is thought to be better suited for use in household refrigerators. It has a lower global warming potential but is protective for the ozone layer. R152a and R600a were combined in this study's refrigerant mixture at a 76:24 mass ratio. By ASHRAE, this blend is known as R430A. It is almost azeotropic with zero ODP and low GWP (Global Warming Potential) of 107. It is regarded as an R134a substitute that can work. A theoretical performance study was conducted using the REFPROP 9.0 database software as a property reference. The alternative refrigerants selected had better properties than R134a. In addition, the refrigeration cycle performance of R134a and R430A was analyzed using CYCLE_D software to predict various performance characteristics. As a result of this study, the selected alternative refrigerant mixture R430A proved to be an excellent substitute for R134a.In terms of zero ODP, low GWP, and environmental friendliness, the suggested combination appears to be an extended-life refrigerant to replace R134a.
