Extends from HVACAgentBasedControl.BaseClasses.PartialCostFunction.
Information
Overview
-
This model determines
the exergy destruction of a mixing valve and a heat exchanger based
on the inputs of the component.
-
It is used together with
an IntermediateAgent.
Concept
Instead of a calculation
with the help of inflowing and outflowing enthaplies, this cost
function calculates the exergy product based on a heat flux. The
estimation of the average temperature of the heat flux causes a small
uncertainty compared to the other approach. However, this cost
function leads to a more stable and reliable simulation. Details can
be found in the reference.
