The database includes and 5 pseudo-pure fluids (such as air). Version 10 introduces critical updates for low global warming potential (GWP) alternatives, adding specialized refrigerants like: R1224yd(Z) R1233zd(E) R1234ze(Z) R1336mzz(Z)
REFPROP 10 (Reference Fluid Thermodynamic and Transport Properties) is the gold standard for researchers and engineers needing high-accuracy thermophysical property data for fluids. Version 10, released by NIST, introduced significant improvements over previous versions, including new equations of state and expanded fluid mixtures. Because it is a highly specialized, proprietary software developed by the National Institute of Standards and Technology, it is not available as a free download. refprop 10 free download 2021
