In this study, the first and second law analysis of Dimethyl ether (DME) and its blend refrigerants(R429A, R435A, R 510A) is presented as an alternatives to R134a. A computational model, developed in cycle_Dsoftware, is employed for comparing the performance of these refrigerants in vapour compression refrigeration cycle.The thermodynamic properties of the DME and its blend refrigerants are computed using Refprop version 9.0. Theparameters computed are volumetric refrigerating capacity, compressor discharge temperature, Co efficient ofperformance and exergy efficiency in system. The results indicate that VRC, COP and exergy efficiency for R134a arelower in comparison with R429A, R435A, R510A.
