REFPROP (Reference Fluid Thermodynamic and Transport Properties) is NIST’s standard reference database for thermodynamic and transport properties of pure fluids and mixtures. Version 9.1 (released around 2013) was a significant update, adding new fluids, enhanced mixture models, and improved computational routines.
In the world of chemical engineering, HVAC design, and cryogenics, few tools are as revered as NIST REFPROP (Reference Fluid Thermodynamic and Transport Properties Database). Developed by the National Institute of Standards and Technology (NIST), REFPROP is the industry standard for calculating the properties of pure fluids and mixtures. refprop 91 free
