Uses the most accurate equations of state available (Helmholtz energy-based), providing properties that closely match experimental data.
In the late 1980s, the world faced a crisis: the ozone layer was depleting due to chlorofluorocarbons (CFCs). Engineers needed to find replacement refrigerants, but they lacked precise data on how these new substances would behave under pressure and temperature. NIST released REFPROP 1.0 in 1989 on a floppy disk to provide those answers. The Evolution to Version 9.0 By the time Version 9.0 refprop 9 0 portable
To create a portable version of REFPROP 9.0 , you can essentially "uncouple" it from the Windows installer by copying its core directory. Since REFPROP is a collection of Fortran-based Uses the most accurate equations of state available
The installation process for REFPROP 9.0 Portable is straightforward. Simply download the software from the website and follow the installation instructions. NIST released REFPROP 1
A "portable" version typically refers to a setup where the software runs directly from a folder without needing to write to the Windows registry. Answers to Frequently Asked Questions - NIST Pages
