Abstract

Detailed knowledge about the solubility of refrigerant in oil is essential for the design, operation, and long-term reliability of HVAC and refrigeration systems. Herein, as the leading candidates, the solubilities of R1234ze(E) in polyol ester (POE), polyvinylether (PVE), and polyalkylene glycol (PAG) base oils were investigated using the isochoric saturation method at temperatures from 283 K to 353 K. The viscosity grade of the three base oils is ISO VG 68. Additionally, the Peng-Robinson (PR) + Wilson model was successfully applied to correlate the experimental data. The absolute average relative deviations between the experimental and calculated pressures for R1234ze(E) in POE, PVE, and PAG base oils were 1.56 %, 0.91 %, and 1.46 %, respectively. These results provide valuable physical property data for the selection of suitable oils in vapor compression refrigeration systems.
