NIST Reference Fluid Thermodynamic and Transport Properties - REFPROP. REFPROP is an acronym for REFerence fluid PROPerties. This program, developed by the National Institute of Standards and Technology (NIST), provides tables and plots of the thermodynamic and transport properties of industrially important fluids and their mixtures with an emphasis on refrigerants and hydrocarbons, …

(If it is not there, press "User defined" and A new function is available to allow users to call Refprop with one single command that replaces most other calls from 9.1 (thus removing the need to learn what routines to use and the inputs/outputs for each routine, such as TPFLSH, THERM, etc.) However, the … 2014-03-21 they are also accessible through spreadsheets or user-written applications accessing the REFPROP dll. REFPROP is based on the most accurate pure fluid and mixture models currently available. It implements three models for the thermodynamic properties of pure fluids: equations of state explicit in Helmholtz energy, the modified 2015-09-02 2017-09-01 Load multiple copies of the DLL in memory: You can load multiple copies of the REFPROP dll into memory with the code at https://github.com/usnistgov/REFPROP-manager; Call the REFPROP library (wrappers): Want to call REFPROP from Python, Excel, C#, Labview, etc.? There are wrappers available at https://github.com/usnistgov/REFPROP-wrappers Enthalpy is the function in units of [kJ/kg]. Other functions supported by MiniRefProp include Temperature [K]; Pressure [MPa]; Density [kg m -1 ]; Volume [m 3 kg -1 ]; Quality [-]; Energy [kJ/kg] ( note: REFPROP support on OSX ¶ The refprop dylib (with the correct bitness!), as well as the fluids and mixtures folders of REFPROP should be placed in the folder refprop inside /Users/$ {USER}/Library/Group Containers/UBF8T346G9.Office. Make sure the shared library is called librefprop.dylib. Additionally, properties contained under the derivative tab include most of the common derivatives of density, pressure, temperature, and enthalpy with respect to each other.

It works with the same function calls as REFPROP in MATLAB and it gives you the full functionality in terms of the fluids and mixtures available. I definitely prefer it over REFPROP these days. The only caveat to this that the MATLAB interface is simply a Python wrapper. More information.

Select the REFPROP category to see all available functions. (If it is not there, press "User defined" and then find it). A new function is available to allow users to call Refprop with one single command that replaces most other calls from 9.1 (thus removing the need to learn what routines to use and the inputs/outputs for each routine, such as TPFLSH, THERM, etc.) However, the old routines are still available for backwards compatibility. Macros in Excel must be enabled to calculate properties. The help file in the REFPROP graphical interface (REFPROP.exe) gives additional information on calculating properties or running macros from any spreadsheet.

Otherwise, it is a maintenance nightmare since you can't version control VBA code.
