: Refinements for low-global-warming-potential (GWP) refrigerants like R-1234yf and R-1234ze(E).
Version 9.1 was a major milestone that introduced optimized Fortran code for faster calculations and improved convergence. Even with newer versions available, many legacy systems still rely on its core routines like TPFLSH and THERM . Key Features: refprop 91 free

RefProp 9.1 is a legacy version of the software. While NIST has since released version 10.0, many engineers and researchers still look for 9.1 due to its compatibility with older plugins, Excel macros, or specific research citations. Why RefProp Isn't Free
When you search Google or torrent sites for "refprop 91 free," you will find links to executable files, keygens, and patch files. Here is what you are actually downloading: Even with newer versions available, many legacy systems
developed by the National Institute of Standards and Technology (NIST) and is not available for free in its full version.
