Selected Thermodynamic Properties for Mixtures of R-32 (Difluoromethane), R-125(Pentafluoroethane), R-134A (1,1,1,2-Tetrafluoroethane), R-143A (1,1,1-Trifluoroethane), R-41 (Fluoromethane), R-290 (Propane), and R-744 (Carbon Dioxide)

摘要

Thermophysical property measurements were carried out on one pure fluid, tenbinary mixtures, and one ternary mixture which are potential HCFC alternatives. Vapor-liquid equilibrium, near-saturation density, pressure, volume temperature, heat capacity, and vapor phase, speed of sound data were measured over wide ranges of temperature and pressure.
