REFPROP (REFriference Fluid PROPerties) is a computational database developed by NIST to provide highly accurate thermophysical properties for industrially important fluids and their mixtures. It has become the global standard for the refrigeration, natural gas, and aerospace industries because it implements the most precise models available, primarily based on Helmholtz energy equations of state. These models ensure thermodynamic consistency across gas, liquid, and supercritical states. Differences Between Versions While the full NIST REFPROP 9

Accuracy: Uses many of the same high-accuracy equations of state found in RefProp. 🧪 Cantera
