modelPartialEightPortInterface
Partial model transporting fluid between eight ports without storing mass or energy
Extends from IBPSA.Fluid.Interfaces.EightPort (Partial model with eight ports).
Information
This component defines the interface for models that transport four fluid streams between eight ports. It is similar to IBPSA.Fluid.Interfaces.PartialTwoPortInterface, but it has eight ports instead of two.
The model is used by other models in this package that add heat transfer, mass transfer and pressure drop equations.
