Property calculation of LiBr-H2O mixture for modelling of Vapour absorption refrigeration system.

[Rishu2425]

I am modelling a single effect Lithium Bromide (LiBr)- Water (H2O) based Vapour absorption refrigeration system in Python.
Therefore, I need to calculate the properties of the LiBr-H2O mixture at different temperatures, pressures, and concentrations. In RefProp, there is no ".FLD" file available for LiBr, nor LiBr-H2O mixture is defined in the list of mixtures.

Can anyone help me with this? How can I get the ".FLD" file of LiBr, or how can I calculate the property of the LiBr-H2O mixture?

Thank you in advance

REFPROP does not have any capabilities for handling electrolyte systems.
You will need to find another tool for this problem. Commercial process simulation packages typically have the ability to model aqueous electrolytes, but they would likely be much more expensive than REFPROP.

CoolProp has LiBr+H2O correlations for incompressible working fluids, but doesn't have all the contributions required to model absorption systems. There have been a number of requests along those lines over the years.
