: It can be used via a standalone Windows graphical interface or integrated into external applications like using its dynamic link library (DLL). ScienceDirect.com Common Applications Refrigeration and HVAC

If you are currently working on a simulation or implementation using this software, let me know: nist refprop 9

For many engineers, the most valuable feature of Version 9 was its seamless integration with Microsoft Excel. REFPROP 9 installs as an Excel Add-In, allowing users to call fluid properties directly inside spreadsheet cells using custom formulas (e.g., =RP("TP","D", T, P, Fluid) ). This functionality allows for rapid parametric studies and system modeling without learning a complex coding language.

The National Institute of Standards and Technology (NIST) has been a leading authority in providing accurate and reliable scientific and engineering data for decades. One of their most renowned databases is REFPROP, a comprehensive thermophysical properties database that has become an essential tool for researchers, engineers, and scientists worldwide. In this article, we will explore the features, capabilities, and applications of NIST REFPROP 9, the latest version of this powerful database. Engineers use the database to model organic Rankine

For a given state (e.g., temperature and pressure), REFPROP 9 calculates:

The GUI in v9 is with separate windows for: This functionality allows for rapid parametric studies and

It doesn't rely on simple, "back-of-the-napkin" calculations. Instead, it utilizes the most accurate physical models currently available, primarily the for pure fluids. This ensures that the data you pull—whether it's density, heat capacity, or surface tension—is as close to the experimental reality as physically possible.
