Thermodynamic properties of low-GWP alternative refrigerants.

Number: pap. n. 443

Author(s) : FUKUSHIMA M., HAYAMIZU H., HASHIMOTO M.

Summary

Thermodynamic properties of HFO-1123 (CF2=CHF), including critical parameters, vapor-liquid coexistence curve, vapor pressure and PVT properties, were determined experimentally. The measurements of vapor liquid coexistence curve in the critical region were made through visual observation of the disappearance of meniscus at the vapor-liquid interface within an optical cell. The vapor pressure and the PVT properties were made using the constant-volume method. The saturated liquid densities were obtained by the method using pyrex glass floats. The new experimental data and correlations were presented.
