All Refrigerant PT Charts
34 refrigerants with pressure-temperature saturation data. Every chart lists saturation pressure in PSIG, PSIA, kPa and bar in 5°F steps, calculated from NIST reference equations of state via CoolProp. Zeotropic blends with temperature glide also list vapor (dew) pressure. Use the vapor column for superheat and the liquid column for subcooling. GWP values are IPCC AR4 100-year figures, the basis used by the EPA's AIM Act rules.
