Abstract

A recently built experimental setup was employed for the estimation of the solid-liquid equilibria of alternative refrigerant systems. The behavior of two binaries, i.e., carbon dioxide + 1,1-difluoroethane (CO + R152a) and nitrous oxide + 1,1-difluoroethane (N O + R152a), was measured down to temperatures of 132 K. The triple points of CO and N O were measured to confirm the reliability of the apparatus. The triple point of R152a was also measured; however, the pressure at the triple point for this fluid was too low to accurately measure with the current apparatus. All triple-point data measured revealed a generally good consistency with the literature. The results obtained for the mixtures were interpreted by means of the Schröder equation.
