modelDistributor
Heating circuit distributor for underfloor heating systems
Extends from AixLib.Fluid.Interfaces.LumpedVolumeDeclarations.
Information
Overview
Model for a contributor for different floor heating circuits in a house.
Concept
The contributor is built to connect n floor heating circuits together. The volume is used for nummerical reasons, to have a point where all the flows mix together.
