Refrigerant pressure–temperature charts
The saturation line of every refrigerant the catalog's 14,438 compressor maps run on — 26 fluids — as a pressure–temperature table in kPa, bar and psig every 5 K, with the latent heat, the liquid and vapour densities and, on a zeotrope, the bubble line and the glide. Each chart lists the machines on its fluid.

Computed with CoolProp 8.0.0, the open-source property library the solver runs on; pressures are absolute, the boiling point is the dew temperature at 101.325 kPa, and the glide is the dew-to-bubble difference at one pressure. Superheat is measured from the dew line and subcooling from the bubble line — superheat, subcooling.
