modelMixingValveAndHEX_ExergyDestruction
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
The figure above shows the control volume for the mixing valve and heat exchanger. Based on this volume the following function for exergy destruction has been developed. Details can be found in the reference.
