R407F pressure–temperature chart
R407F is a zeotropic blend. Its normal boiling point is -39.7 °C. At the AHRI 540 air-conditioning rating point — 7.2 °C evaporating, 54.4 °C condensing — the saturation pressures are 6.65 and 24.60 bar, a pressure ratio of 3.70. As a zeotropic blend it evaporates and condenses over a range of temperatures at one pressure — a glide of 5.6 K at 0.0 °C — so the dew line (where the last liquid boils off) and the bubble line (where the first vapour forms) are both tabulated. Superheat is measured up from the dew temperature and subcooling down from the bubble temperature; a map's 8.3 K of subcooling is 8.3 K under the bubble line, not the dew line, and this solver reads it so.

Pressures are absolute in kPa and bar, gauge in psig (at 101.325 kPa atmospheric); hfg is the latent heat of vaporisation at the dew pressure; densities are saturated liquid and saturated vapour. Computed with CoolProp 8.0.0, the open-source property library the solver runs on, sampled every 0.5 K and printed every 5 K — the same tables the builder reads when it solves a circuit on R407F.

Open the R407F chart in the app — the pressure–temperature line drawn, readable at any point, with a compressor's envelope over it — or open the builder and draw a circuit on R407F: the solver finds its evaporating and condensing temperatures from the coils and the compressor's map.
