A thermodynamic model based on the extended
corresponding states principle has been developed to
calculate the solubilities of nitrogen in five selected
agents, HFC-227ea, CF3I, FC-218, HFC-125, and CF3Br and
the pressure-temperature relationship for agent/nitrogen
mixtures. The model only requires four pieces of input
information: (1) agent mass, (2) vessel volume, (3)
fill temperature, and (4) either nitrogen mass needed to
pressurize the vessel or the fill pressure of the
vessel. Comparing to the experimental data obtained at
150 deg C and -60 deg C, the model predictions were
generally found to be within 10% or less of the
