Refprop 91 Install Official

Introduction: The Gold Standard in Fluid Properties

For decades, the National Institute of Standards and Technology (NIST) has maintained REFPROP (short for REfrigerant PROPerties) as the definitive program for calculating thermodynamic and transport properties of fluids. Version 9.1, while not the absolute latest release, remains widely used due to its stability and compatibility with older simulation platforms like EES, MATLAB, and LabVIEW. refprop 91 install

However, installing REFPROP 9.1 on modern Windows operating systems (Windows 10/11) is not always plug-and-play. Legacy installer issues, 32-bit vs. 64-bit conflicts, and licensing hurdles are common. This article provides a step-by-step guide to a successful installation.

Before diving into the installation mechanics, it is worth understanding why someone would specifically seek out version 9.1 rather than newer versions (10.0, 9.2, or the current 11.0). The reasons include: If you need refprop 91 install , you

If you need refprop 91 install, you are likely either an academic revisiting legacy coursework, a researcher replicating published results, or an industry veteran maintaining older simulation platforms.

Some older installers trigger false positives in modern antivirus software (e.g., Windows Defender, McAfee). The installer uses self-extracting archives that may be flagged as suspicious. Disable real-time protection just for the installation duration, then re-enable it afterward.

REFPROP 9.1 includes a MATLAB interface via refpropm.m. Copy the script from the installation folder to your MATLAB working directory. Usage example:

[rho, h, s] = refpropm('DH','T',300,'P',101.325,'water');
