Résumé

The viscosity of refrigerant is indeed crucial for the design and optimization of refrigeration systems. In this study, the viscosity characteristics of two potential binary refrigerant mixtures, R-454B and R-454C, which have gained interest as low global warming potential (GWP) alternatives to high-GWP refrigerants were measured by using tandem the capillary tubes method. The experimentally measured viscosity values are presented for two fluids in the liquid phase over broad temperature range of -40°C to 40°C. Additionally, for R-454B in the vapor phase, viscosity measurements are reported at 40°C. The extended uncertainty in measuring viscosity was calculated to be less than 3.0%. The difference between experimental value and REFPROP version 10.0 was the maximum -4.05% and the average absolute deviation (AAD) was -2.87%. This study contributes to the understanding of the thermophysical properties of R-454B and R-454C, which will assist in the selection and design of ecologically friendly refrigeration systems.
