modelBoiler_ExergyDestruction_Simplified
Extends from HVACAgentBasedControl.BaseClasses.PartialCostFunction.
Information
Overview
- This model determines the exergy destruction of a boiler based on the inputs of the component.
- It is used together with a HeatProducerAgent.
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.
