.ThermofluidStream.Media.XRGMedia .ThermofluidStream.Media.XRGMedia
This library contains property functions written in Modelica for the refrigerants R134a, NH3 (R717), CO2 (R744), R1234yf and R245fa. The property models use the Modelica.Media specification for two-phase media (Modelica Standard Library version 3.2.3). The functions supplied may be used separately.
The library is a product of XRG Simulation GmbH. It makes use of external, non-commercial models supplied by Modelica standard library. In order to work correctly, ensure that this library is always loaded with Modelica Standard Library version 3.2.3
Some parts of this library refer to the ThermoFluid library developed at Lund University (sourceforge.net/projects/thermofluid/).
Please refer to Modelica.Media's User Guide for detailed usage information.

 R134a_ph | XRG_Media: medium model for R134a and p,h as states |
 R134aData | R134a data required by package R134a_ph |

2021-06-14 XRG Simulation GmbH - Stefan Wischhusen: Free version to be part of DLR's ThermoFluidStream Library. Includes maintenance of dofpT iteration and setState_dTX.
2019-06-13 XRG Simulation GmbH - Johannes Brunnemann: Migration to MSL 3.2.3.
2017-12-08 XRG Simulation GmbH - Stefan Wischhusen: Migration to MSL 3.2.2. Added missing setState_pTX functions to all media models.
2013-12-04 XRG Simulation GmbH - Stefan Wischhusen: Migration to MSL 3.2.1. Introduced missing function icons. Added an assertion in setState_pTX functions notifying the user to omit the use of this function (setState_pTX is defined by PartialMedium interface but not useful for two-phase media). Specific heat capacity in two-phase is changed to 0 instead of infinity (which would be physically correct) for tool-vendor reasons.
2013-08-30 XRG Simulation GmbH - Stefan Wischhusen: Added medium Pentafluoropropane (R245fa).
2013-01-09 XRG Simulation GmbH - Stefan Wischhusen: Migration to MSL 3.2.1 Interface. Added functions for R134a.
2012-04-27 XRG Simulation GmbH - Stefan Wischhusen: Added new refrigerant R1234yf and additional functions. Helmholtz functions have been structured in a new way. Coefficients of phase boundaries were updated.
2011-03-17 XRG Simulation GmbH - Stefan Wischhusen: Fixed problems with functions for calculation of thermal conductivity at phase boundaries.
