Once upon a time in the high-stakes world of thermodynamic research, an engineer named Sarah faced a daunting challenge. Her mission: install REFPROP 9.1 , the legendary software from
: A licensed copy of the REFPROP 9.1 setup executable (typically named Setup.exe or delivered via a digital download link from NIST). 2. Standard Desktop Installation
Before beginning the installation, ensure your system meets the following requirements:
) file and meticulously moved it to a trusted folder, avoiding the treacherous default path that Excel often rejected. The Connection: Through the Excel
To call REFPROP from external programming environments without explicitly hardcoding file paths, you must add REFPROP to your Windows System Path. refprop 91 install
To install NIST REFPROP version 9.1, follow these standard procedures as outlined in the official NIST REFPROP 9.1 User's Guide Installation Steps System Requirements
Installing is a straightforward process, but it requires careful adherence to steps to ensure all DLL files, fluids, and mixtures function correctly within your thermodynamic modeling environments (e.g., Excel, MATLAB, Python).
This guide applies to REFPROP Version 9.1 (circa 2013). For the latest updates, please visit the official NIST REFPROP website.
After installation, you'll need to activate RefProp 9.1 using a license file. To obtain a license file: Once upon a time in the high-stakes world
: Windows 7, 8, 10, or 11 (32-bit or 64-bit).
Administrative privileges on the target computer.
Complete Guide to Installing and Configuring REFPROP 9.1 NIST Reference Fluid Thermodynamic and Transport Properties Database (REFPROP) is the industry standard for predicting the thermophysical properties of fluids. Version 9.1 remains widely used in engineering and research for its reliability and compatibility with legacy simulation code. This guide provides a complete, step-by-step walkthrough to successfully install and integrate REFPROP 9.1 on your system. 1. Prerequisites and Installation Package
Recommendation: Installing in C:\REFPROP is often preferred to avoid permission issues with Program Files when updating fluid files later. This guide applies to REFPROP Version 9
REFPROP 9.1 is a significant update to the REFPROP series, offering improved performance, new features, and enhanced accuracy. The software provides a comprehensive database of fluid thermodynamic properties, including equations of state, vapor-liquid equilibrium, and transport properties. REFPROP 9.1 supports over 1000 fluids, including refrigerants, hydrocarbons, and other common working fluids.
Copy the refpropm.m file from the scripts folder in your REFPROP directory to your MATLAB work folder. You will also need to ensure the REFPROP.DLL is accessible in the system path. Python (CoolProp Wrapper)
If you need to get REFPROP 9.1 up and running on your machine, follow this comprehensive installation and setup guide. 1. System Requirements & Prerequisites Before beginning, ensure your system meets the following:
Ensure all components (Fluid files, Mixture files, and Help files) are checked. Click and wait for the progress bar to finish. Click Finish to close the setup wizard. 3. Configuring Environment Variables (Critical Step)
One of the most common ways to use REFPROP is within Microsoft Excel. To link version 9.1 to Excel: Linking REFPROP with Other Applications
REFPROP 91 is a powerful tool for calculating thermophysical properties of pure fluids and mixtures. By following the installation steps outlined above, users can easily install and activate the software. With its comprehensive fluid list, accurate property data, and user-friendly interface, REFPROP 91 is an essential resource for researchers, engineers, and students working with thermodynamic properties.
