Liquid water-hydrate-vapor (L-W-H-V) and ice-hydrate-vapor (I-H-V) three phase equilibrium data of 1,1,1,2-tetrafluoroethane (HFC-134a), 1,1-dichloro-1-fluoroethane (HCFC-141b) and 1,1-difluoroethane (HFC-152a) have been reported in this paper. The data were measured in a sapphire cell with magnetic stirrer and data acquisition system over a range of temperature (265.31-283.13, 268.41-281.49 and 264.72-288.15 K, respectively) and a range of pressure (6-440, 6.2-40.2 and 49.5-443.7 kPa, respectively). Kihara potential parameters have been obtained based on the experimental data.
