Portable software is a program designed to run on any Windows computer without requiring formal installation, writing to the Windows registry, or leaving configuration files scattered across the system. A portable application typically:
For most engineering applications, CoolProp provides accuracy that is comparable to REFPROP. However, users should be aware that some differences can occur, particularly for certain mixtures. For example, one reported issue showed that for R1233zd(E), CoolProp gave a different saturation temperature than REFPROP, highlighting that even when both use similar equations of state, implementation details and version differences can lead to discrepancies.
Within the copied folder, locate REFPROP.EXE and run it. The program should load, and the fluid data should be accessible. refprop 9 0 portable
CoolProp is truly portable. As an open-source library, it can be:
Test the portable copy by running REFPROP.EXE directly from the USB drive on a different computer. The program should launch and function normally, as the NIST installer does not require a key or other security item to run the program. Portable software is a program designed to run
If you are specifically using the 9.0 "portable" or legacy version, be aware of several documented calculation errors that NIST has addressed in later patches or Version 10: Incorrect
: The models are primarily based on Helmholtz energy equations of state, ensuring uncertainties approach the level of underlying experimental data. Portable & Integrated Use Cases For example, one reported issue showed that for
If you prefer to run from a different location, you may need to move the folder to C:\Program Files\REFPROP as some integration files expect this path.
: Subfolders containing .FLD (fluid) and .MIX (mixture) files, which hold the pure fluid constants and equations of state coefficients. How to Configure a Legal Portable Environment
It calculates properties such as density, enthalpy, entropy, viscosity, thermal conductivity, and speed of sound for pure fluids and mixtures.
