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 8.0.1dev, 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 R507A.
247 compressor maps run on R507A, each a page with its AHRI 540 / EN 12900 map across the published envelope, and each selectable in the builder. Read any of them at your own evaporating and condensing temperatures →
Open the builder — draw a circuit on R507A, and the solver finds its evaporating and condensing temperatures from the coils and the compressor's map.
