It increased the library to 105 pure fluids, including environmentally "natural" refrigerants like ammonia and CO2. The 9.1 Bridge:
Version 9.0 supports over 120 pure fluids and 200 predefined mixtures , including refrigerants, hydrocarbons, and natural gases. refprop 9 0 portable
NIST offers a free, limited version called mini-REFPROP which includes common fluids like water, CO2, and R134a . It increased the library to 105 pure fluids,
(Reference Fluid Properties) is a widely used database developed by the National Institute of Standards and Technology (NIST) for calculating the thermodynamic and transport properties of industrially important fluids and their mixtures. While NIST does not distribute a standalone "portable" version of the full software, a reduced-property sample version called MINI-REFPROP is often used as a lightweight, portable teaching tool.

REFPROP 9.0 remains a highly respected, "gold standard" tool for thermophysical fluid property calculations, though it has since been superseded by Version 10.0 . Key Strengths
