Buildings.Fluid.Data.Fuels

Package with properties of fuels

Information

Package with records for fuel properties. Note that the heating value and the mass density can vary for individual fuels. The parameter mCO2 are the CO2 emission in kilograms that are released per kilogram fuel that is burnt.

Extends from Modelica.Icons.MaterialPropertiesPackage (Icon for package containing property classes).
