Title: Controls Oriented Modeling of Complex Hydronic Systems.

Speaker: Vikas Chandan

Abstract: Residential and commercial buildings consume around 40% of the total energy in the United States and also account for significant greenhouse gas emissions. More than one third of this impact can be attributed to the heating and cooling systems employed in these buildings. Centralized hydronic systems are widely used to meet the thermal requirements in most existing buildings. Energy efficient operation of such systems requires intelligent energy management strategies, which necessitates an understanding of the complex dynamical interactions among its components from a mathematical and physical perspective. This talk shall present the application of concepts from linear graph theory for modeling complex hydronic networks. Further, the use of time-scale decomposition techniques will be described to obtain a more succinct representation of the overall system dynamics. Lastly, the usefulness of the proposed modeling framework for energy efficient operation of the system through advanced control techniques shall be discussed.
