Development of Alternative Binary Mixtures to Replace HFC 134a in Domestic Refrigerator

Development of Alternative Binary Mixtures to Replace HFC 134a in Domestic Refrigerator

Thermodynamic and volumetric properties of alternate Refrigerant mixtures to replace R134a have been predicted using SRK EOS and modified PSRK mixing rule using UNIFAC method. The performance of alternate refrigerant mixtures has been comparatively assessed using standard refrigeration parameters su...
