Comparative Analysis of Cop Using R134a & R600a Refrigerant in Domestic Refrigerator at Steady State Condition

M.Abuzar Qureshi | Shikha Bhatt

Abstract: The aim of this project is to comparatively analyze of COP using R134a & R600a Refrigerant in Domestic refrigerator at steady state condition. Two different refrigerant are R600a (Isobutene) and R134a (tetrafluoroethae). R134a is zero ozone depletion layer and high global warning and R600a is zero ozone depletion layer and negligible global warning. In domestic refrigerator was selected by the obtained result from R134a and an experiment using 50 g of R600a which indicate the similar result as R134a. Based on outcomes R600a charge amount, condenser evaporator and compressor coefficient of performance were selected for design. The analysis of variance result is indicated that R600a charge amount was the most effective parameter. At optimum condition the amount of charge is required for R600a was 50 g, 66 % lower than R134a one, which not only being economic advantages, but also significantly reduces the of flammability of the hydrocarbon refrigerant. Thus in the present work comparatively analyze of COP using R134a & R600a Refrigerant in Domestic refrigerator at steady state condition. All the result were compared. Comparison of performance domestic refrigerator at steady state condition of the system was also studied. The result is indicate that R600a COP is mere then R134a.
