packagePropyleneGlycolWater
Package with model for propylene glycol - water with constant properties
Extends from Modelica.Icons.Package (Icon for standard packages).
Information
This medium package models propylene glycol - water mixtures.
These functions are identical with the ones in Buildings.Media.Antifreeze.PropyleneGlycolWater. See therefore the documentation of that package.
