While every version of REFPROP is powerful, version 9 introduced features that made it a watershed release for engineers who prefer a stable, legacy-compatible platform.
REFPROP 9 includes properties for:
One of REFPROP’s strongest selling points is its ability to handle mixtures. REFPROP 9 allows users to define mixtures of up to 20 components. This is vital for industries dealing with natural gas processing or custom refrigerant blends. The software uses advanced mixing rules to predict how these different molecules interact, providing accurate phase-envelope data. nist refprop 9
For many engineers, the most valuable feature of Version 9 was its seamless integration with Microsoft Excel. REFPROP 9 installs as an Excel Add-In, allowing users to call fluid properties directly inside spreadsheet cells using custom formulas (e.g., =RP("TP","D", T, P, Fluid)). This functionality allows for rapid parametric studies and system modeling without learning a complex coding language. While every version of REFPROP is powerful, version
Mixtures require GERG-2008 (or simpler mixing rules). This is vital for industries dealing with natural
