Installing NIST REFPROP 9.1 typically involves the base software installation on Windows followed by linking the Dynamic Link Library (DLL) to applications like Excel, MATLAB, or Python. 1. Core Software Installation (Windows) REFPROP 9.1 is a licensed software provided by NIST. Run the Installer
If you encounter issues during installation or while using REFPROP 9.1, refer to the:
The easiest way to use REFPROP 9.1 in Python is by using the ctREFPROP wrapper or utilizing CoolProp as an intermediary wrapper. pip install urllib3 CoolProp Use code with caution.
The installation of (Reference Fluid Properties) follows a specific process depending on whether you are using the standalone program or integrating it with Microsoft Excel. Core Installation Steps refprop 91 install
Select a fluid (e.g., Water) and calculate a property. If the result appears, installation is successful.
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:
Tell Python where your REFPROP installation is by setting an environment variable inside your script: Installing NIST REFPROP 9
In your script, you will point the wrapper to your C:\Program Files (x86)\REFPROP directory to load the high-accuracy NIST fluid files. 5. Troubleshooting Common Issues
REFPROP, short for erence Fluid PROP erties, is a program developed and distributed by the National Institute of Standards and Technology (NIST) as Standard Reference Database 23 (SRD 23). It is a cornerstone for engineers and scientists working with refrigerants, hydrocarbons, natural gas, and other industrially important fluids, particularly in fields like HVAC&R, chemical engineering, and energy systems.
The primary installation typically occurs from a CD-ROM or an executable installer file. Run the Installer If you encounter issues during
Ensure the .dll files are present in the C:\Program Files\REFPROP folder and that the location is added to your system's PATH variable, if necessary.
REFPROP is not merely a database of measured values; it is a powerful calculation engine. It uses some of the most accurate pure fluid and mixture models available, typically equations of state explicit in Helmholtz energy, to predict properties across a wide range of liquid, gas, and two-phase states.
