Version Control: Easily switch between 9.0 and newer versions (like 10.0) without installation conflicts. How to Create a Portable Refprop 9.0 Directory refprop 9 0 portable

2. REFPROP 30-Day Trial (Official)

NIST offers a fully functional 30-day trial of REFPROP 9.1 (still available via legacy download). No crack needed. You simply download the installer, run it, and it works for 30 days. For a one-off project, this is more than enough. You're looking for a review of RefProp 9

Extensive Database: Support for 121 pure fluids and hundreds of mixtures. By default, Refprop 9

Key Features

• Fluid database: Comprehensive library of pure fluids (refrigerants, common gases, hydrocarbons, cryogens) with equations of state, critical properties, and reference states drawn from NIST data.
• Mixture calculations: Multi-component mixture property evaluation using mixing rules and association models where appropriate.
• Thermodynamic properties: Extensive outputs including pressure, temperature, density, enthalpy, entropy, internal energy, heat capacities (cp, cv), speed of sound, compressibility factor, and derivatives.
• Transport properties: Viscosity, thermal conductivity, diffusion coefficients, and models for mixture transport properties.
• Phase equilibrium: Vapor–liquid equilibrium (VLE), dew/bubble point calculations, critical point estimates, and phase identification across two-phase regions.
• Interfaces: Command-line tools, DLL/API for integration with other engineering software (MATLAB, EES, LabVIEW), and basic GUI in some portable builds.
• Units and reference states: Flexible unit systems, reference-state options, and the ability to export data for use in spreadsheets or simulations.

By default, Refprop 9.0 is designed to be installed on a Windows operating system with specific registry keys and file paths. However, the core of the program relies on a collection of DLLs and fluid files (.FLD and .MIX). Because these files are self-contained, you can essentially "portabilize" the software by maintaining the correct folder structure. Why Use a Portable Version?

"Portable" Integration: While it typically installs to a hard drive, its true portability lies in the REFPROP.DLL. This allows you to "carry" the engine into third-party software like Excel, MATLAB, or custom Python scripts. Pros REFPROP | NIST
