A new experimental setup was built for the estimation of the solid liquid equilibria of alternative refrigerant systems. The system’s behavior was measured down to temperatures of 143 K using two binaries (i.e., carbon dioxide 1,1,1,2,2-pentafluoroethane (CO 2 R125) and nitrous oxide 1,1,1,2,2-pentafluoroethane (N 2 O R125)). The setup enabled us to record not only temperature and composition data but also pressure data. The triple points of the pure fluids contained in the mixture were measured to check the reliability of the new apparatus, revealing a good consistency with the literature. The results obtained for the mixtures were interpreted by means of the Schro¨der equation.

Abstract
A new experimental setup was built for the estimation of the solid liquid equilibria of alternative refrigerant systems. The system’s behavior was measured down to temperatures of 143 K using two binaries (i.e., carbon dioxide 1,1,1,2,2-pentafluoroethane (CO 2 R125) and nitrous oxide 1,1,1,2,2-pentafluoroethane (N 2 O R125)). The setup enabled us to record not only temperature and composition data but also pressure data. The triple points of the pure fluids contained in the mixture were measured to check the reliability of the new apparatus, revealing a good consistency with the literature. The results obtained for the mixtures were interpreted by means of the Schro¨der equation.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
