I am attaching a sim file where specific heats for EG-H2O mixture plays an important role in determing cooling loads.
The actual values are 3.7-3.8 for 40% w.t ...but DWSIm puts it at 1.6kJ/kg.K
source: https://simulationresearch.lbl.gov/modelica/releases/v9.1.0/help/Buildings_Media_Antifreeze_EthyleneGlycolWater.html
the actual value depends on the property package + enthalpy/cp method selected.
you should have used an activity coefficient model instead of PRSV2.
I will do that ...can you provide an excample of how to use 'Property override' in this case for Cp
open the viscosity override sample, the procedure is similar
