Measurements of the saturated liquid density for HFC-134a + oil mixtures.

Author(s) : SATO T., TAKAISHI Y., OGUCHI K.

Summary

The paper reports experimental results of the saturated liquid density for four combinations of HFC-134a and its compatible lubricants such as polyalkyleneglycol (PAG) and polyolester (POE) oils. The saturated liquid density is measured by the method using spherical buoys made of glass. The experiments have been conducted for temperatures from 256 to 313 K, densities from 933 to 1327 kg/m3 and oil concentrations from 0 to 1. The results show that the saturated liquid density for HFC-134a + oil mixtures decreases with increasing oil concentration at a constant temperature while showing slightly positive or negative deviations from the mass fraction average for the experimental temperatures concerned.
