REFPROP is a commercial product. You must have the REFPROP91.EXE setup file or the physical media purchased from NIST.
At the bottom, select from the "Manage" dropdown and click Go .
Example: density = refpropm('D', 'T', 300, 'P', 101.325, 'water')
To use REFPROP 9.1 in MATLAB, you need a wrapper file (often provided in the MATLAB subfolder of the installation). In MATLAB, use addpath('C:\Program Files (x86)\REFPROP') . Use the refpropm.m function to call properties.
Pro-tip: If you plan on using Python or MATLAB extensively, some users prefer installing to a simpler path like C:\REFPROP to avoid permission issues or "Space in filename" errors in code.
Ensure that "Full Installation" is selected so that all fluid files (.fld) and mixture files (.mix) are included.
If you have CoolProp installed, you can call REFPROP fluids by setting the "Alternative Path."
Ensure your MATLAB bit-version matches the DLL (use a 64-bit wrapper if using 64-bit MATLAB). 5. Connecting to Python
This happens if the program doesn't know where the /fluids folder is. Go to the REFPROP GUI, select Options > Paths , and ensure the path points to your installation folder.
By default, the installer suggests C:\Program Files (x86)\REFPROP .
