Calling SETUPdll and REFPROPdll functions allows you to calculate density, viscosity, and entropy in real-time inside your own simulation code.
Note to users: REFPROP 9 does not include newly developed refrigerants like R1233zd(E) or R1336mzz(Z) – those came in version 10. nist refprop 9
Universities use REFPROP 9 as the ground truth for validating simpler correlations or teaching thermodynamics. NIST databases are the gold standard for scientific publication. Calling SETUPdll and REFPROPdll functions allows you to
Version 9 included 105 pure fluids and allowed for the calculation of properties for mixtures with up to 20 components. ResearchGate import REFPROP 9 data into a specific programming environment like NIST databases are the gold standard for scientific
By version 9, the GUI had become intuitive. Users could generate saturation tables, isobaric property plots, and PT diagrams with a few clicks. The "Calculate" menu allowed rapid flash calculations using PT, PH, PS, or TV inputs.
While the software has evolved over the years, represents a significant milestone in the history of thermophysical property calculation. Released as a major update to the REFPROP series, Version 9 brought substantial improvements in the accuracy of mixture equations, the implementation of new models, and the expansion of its already massive fluid database.
REFPROP 9 utilizes the formulation: $$A(\rho, T) = A^0(\rho, T) + A^r(\rho, T)$$
