Buildings.Media.Antifreeze.Validation.EthyleneGlycolWater

Model that tests the implementation of ethylene glycol-water properties

Information

This example checks the implementation of functions that evaluate the temperature- and concentration-dependent thermophysical properties of the medium.

Thermophysical properties (density, specific heat capacity, thermal conductivity and dynamic viscosity) are shown as 0 if the temperature is below the fusion temperature.

Extends from Modelica.Icons.Example (Icon for runnable examples), Buildings.Media.Antifreeze.Validation.BaseClasses.FluidProperties (Partial model that tests the implementation of temperature- and concentration-dependent fluid properties).

Buildings.Media.Antifreeze.Validation.PropyleneGlycolWater

Model that tests the implementation of propylene glycol-water properties

Information

This example checks the implementation of functions that evaluate the temperature- and concentration-dependent thermophysical properties of the medium.

Thermophysical properties (density, specific heat capacity, thermal conductivity and dynamic viscosity) are shown as 0 if the temperature is below the fusion temperature.
