Summary

The paper describes two different sets of measurements of the properties of two proposed alternative refrigerants. The first are vapour-liquid equilibrium measurements made in simple variable-volume sapphire cell. The vapour pressures and saturation liquid densities were determined for both materials, between 268 K and the critical temperature for R134a and between 303 and 373 K for R123. The saturation vapour density was also determined. The second set of measurements were made with a vibrating tube densimeter. These data are then compared with other determinations of similar properties.
