For professionals who work across multiple computers, field sites, or need to run simulations without complex installations, a is highly desirable. This article explores what it means to have a "portable" REFPROP 9.0, its benefits, and how to utilize it effectively. What is REFPROP 9.0?
If Excel throws a path error, use the "Find REFPROP" macro function within the add-in to point directly to your portable refprop.dll or refprop64.dll . Python and MATLAB Integration
Instead of installing REFPROP to the operating system, point your Python script directly to your portable folder:
I can provide tailored scripts or step-by-step connection guides based on your environment. Share public link
What are you targeting? (32-bit or 64-bit programs?)
: If the GUI opens but throws an error when selecting a fluid (e.g., Nitrogen, R134a), your relative paths are broken. Recheck the REFPROP.INI file or use the GUI's internal options menu to reset the default fluid lookup path to the current working directory.
A portable setup of provides immense flexibility for engineers who need to carry high-accuracy thermodynamic data in their pocket. It is an excellent way to maintain consistency in simulations, bypass installation issues, and ensure access to reliable property data across multiple devices.
Navigate to your active installation directory (typically C:\Program Files (x86)\REFPROP ). Copy the entire directory structure to your desired portable location, such as a folder on your desktop named REFPROP_9_Portable . Step 2: Configure Relative Paths

Version 9.0 supports over 120 pure fluids and 200 predefined mixtures , including refrigerants, hydrocarbons, and natural gases.
Because the software does not write to the Windows Registry, it won't affect the machine it's running on, making it perfect for quick diagnostics. 4. Compatibility
The NIST Reference Fluid Thermodynamic and Transport Properties Database (REFPROP) is the gold standard for engineers, scientists, and researchers who need accurate thermophysical properties of fluids and mixtures. Version 9.0 remains widely used across industries for its stability and precision. However, standard installations require administrative privileges and hardcoded registry paths, which can limit productivity. Creating a portable version of REFPROP 9.0 solves these issues, allowing you to run calculations directly from a USB drive or shared cloud folder without installation.
