Pressures are absolute in kPa and bar, gauge in psig (at 101.325 kPa atmospheric); h_fg is the latent heat of vaporisation at the dew pressure; densities are saturated liquid and saturated vapour. Computed with CoolProp 8.0.1dev, 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 R22.
