Thermodynamic properties measurements of HFC32 and HFC125.

Summary

Thermodynamic property data of R32 and R125, including critical parameters, vapour-liquid coexistence curve, vapour pressure and PVT properties, were determined experimentally. The measurements of vapour-liquid coexistence curve in the critical region were made through visual observation of the disappearence of meniscus at the vapour-liquid interface within an optical cell. Those of vapour pressure and PVT properties were made using the constant-volume method. Those of saturated liquid density were conducted by the method using pyrex glass floats. The new experimental data and correlations were presented.
