Vapour-liquid equilibria for an R134a/lubricant mixture: measurements and equation-of-state modelling.

Author(s) : HUBER M. L., HOLCOMB C. D., OUTCALT S. L., et al.

Summary

The authors measured bubble point pressures and coexisting liquid densities for two mixtures of R134a and a polyolester (POE) lubricant. The mass fraction of the lubricant was approximately 9 and 12%, and the temperature ranged from 280 to 355 K. They used the Elliott, Suresh, and Donohue (ESD) equation of state to model the bubble point pressure data. They also applied the ESD model to other R134a/POE lubricant data in the literature. As the concentration of the lubricant increased, the performance of the model deteriorated markedly.
