Refprop 91 Free Portable [UPDATED]
Crucially, while mini-REFPROP is a legitimate free tool, it has significant limitations compared to the full, paid software, and NIST provides no technical support for it due to its limited staff.
If you want, I can:
, with upgrades from older versions (like 9.x) costing around Version Status : Version 9.1 has been officially superseded by Version 10
To conclude, here are the best paths forward based on your needs:
For years, this version was the gold standard for engineers who needed to calculate properties like: refprop 91 free
: Includes a massive library of fluids and mixtures.
A fully updated user interface and better support for 64-bit systems.
: Accessible directly via the official NIST TRC mini-REFPROP portal . Option B: Third-Party Trial Managers
One day, a cryptic message appeared on an online forum: "REFPROP 91 Free." The message was posted by a user with the handle "thermo_guru," who claimed to have obtained a free version of REFPROP 91. The post sparked a flurry of interest and curiosity among the forum members. Crucially, while mini-REFPROP is a legitimate free tool,
Fortunately, the thermodynamic community has recognized the need for a free, open-source alternative to REFPROP. That alternative is .
The REFPROP 9.1 free version offers several key features:
Cybercriminals know engineers need REFPROP. They embed Trojans, keyloggers, and ransomware into "cracked" installers. A 2022 study by a cybersecurity firm found that 1 in 3 "engineering software cracks" contained a Remote Access Trojan (RAT).

Greatly expanded database of fluids, particularly for natural refrigerants.
If you are looking for free, high-accuracy thermodynamic data, there are excellent open-source alternatives available. 1. CoolProp
RefProp (Reference Fluid Thermodynamic and Transport Properties) is a highly specialized program developed by the National Institute of Standards and Technology (NIST). It is the industry gold standard for calculating the physical properties of chemicals and refrigerant blends.
It only includes a few fluids (like water, nitrogen, and R134a).
