available worldwide. It wasn't just a database; it was a high-precision engine capable of modeling 105 pure fluids and mixtures with up to 20 components. The "Portable" Evolution
# Example snippet for Python initialization import os from openpyxl import load_workbook # Or your preferred wrapper # Point directly to your portable directory refprop_path = r"D:\PortableApps\REFPROP9" os.environ['RPPREFIX'] = refprop_path Use code with caution. Best Practices and Troubleshooting
To use REFPROP functions inside Excel without installing the software globally: refprop 9 0 portable
Making REFPROP portable does not grant multi-user distribution rights. The software remains proprietary data compiled by NIST. Your portable folder must strictly adhere to the seat limits dictated by your original NIST user license.
The FLUIDS and MIXTURES subfolders must be present for the program to load any substance data . available worldwide
Setting up a portable version usually involves moving the installation files from a standard installation (often located in C:\Program Files (x86)\REFPROP or similar) to a portable folder. 1. File Structure
Version 9.0 of the NIST REFPROP database includes a wide array of pure fluids and mixtures, utilizing the most accurate equations of state available worldwide. Best Practices and Troubleshooting To use REFPROP functions
Disclaimer: Ensure you have a valid license for NIST REFPROP. The official, current version can be purchased directly from NIST.
For a portable setup to work, the directory structure must be maintained: \REFPROP\ (Root Folder) REFPRP.EXE (GUI) REFPROP.DLL (Required for Excel/Python) \FLUIDS\ (Contains .FLD files) \MIXTURES\ (Contains .MIX files) 2. Running the GUI
Do you need to add custom to this portable build?
