modelPartialConnection2Pipe
Partial model for connecting an agent to a two-pipe distribution network
Extends from Buildings.DHC.Networks.BaseClasses.PartialConnection2Pipe2Medium.
Information
Partial model to be used for connecting an agent (e.g. an energy transfer station) to a two-pipe distribution network.
Three instances of a replaceable partial model are used to represent the pipes:
- One representing the main distribution supply pipe immediately upstream the connection.
- Another one representing the main distribution return pipe immediately downstream the connection.
- The last one representing both the supply and return lines of the connection. When replacing that model with a pipe model computing the pressure drop, one must double the length so that both the supply and return lines are accounted for.
