Abstract

The present study analysed the heat transfer and pressure-viscous behaviour of sustainable refrigeration oil/green refrigerant for domestic refrigeration systems. The sustainable refrigeration oil was synthesised from pentaerythritol esters (PE) using the uninterrupted transesterification process. Then the polyol ester-based sustainable refrigeration oil (BIO) was added with synthetic refrigeration oil (POE68) in the fraction of 50% by volume. A high-pressure equilibrium cell/mixing chamber was used for the preparation of a sustainable refrigeration oil/green refrigerant mixture. In this study, the thermal conductivity and piezo-viscosity coefficient of the refrigeration oil/refrigerant blends were also investigated. The results indicate that the BIO50/R600a showed higher thermal conductivity of 8.96% as compared to POE68/R134a. BIO50/R600a exhibits the higher piezo-viscosity coefficient as compared to other refrigeration oil/refrigerant blends, showing the better elastohydrodynamic lubrication (EHL) performance. The usage of a sustainable refrigeration oil/green refrigerant combination in the refrigeration systems will play a substantial role in diminishing the energy demand and environmental effect of high global warming potential refrigerants/fossil energy sources.
