Abstract :
These work subtleties a technique to portray the presence of the capillary tube and Thermostatic expansion valve reasonable for expansion device in the domestic refrigerator just as think about the execution of various refrigerants (R134a, R290, and R600a). In this exploration work, we have investigated different refrigerants utilized in the refrigeration cycle which influence the earth, and our exertion is to diminish the impact of a dangerous atmospheric deviation by using appropriate refrigerants. R-134a is utilized in vapor compression refrigeration system having better thermodynamic properties than other refrigerants and zero ozone depletion potential (ODP), with the exception of Global Warming Potential (GWP). It has 1300 GWP every year. Hydrocarbon refrigerants (HC) for the most part propane, butane and isobutene are proposed as a domain amicable refrigerants. In this way we have utilized the mixed refrigerant of R-134a and R-290. which are ecological cordial, having low GWP, zero ODP. The trial results were contrasted and normally utilized refrigerants R-134a. In this examination work, 40 percent (200g) of R-600a is increasingly proficient on the capillary tube while the productivity is declined by 20 percent on thermostatic expansion valve. The mixed refrigerant of R-134a and R-290 give better execution on the two devices, the COP is increased by 25.8 percent on Thermostatic expansion valve and 22.5 percent on the capillary tube.
