Hydronic optimization of hybrid heat production systems : a methodology based on base circuits
Abstract: Heat is responsible for over 50% of the energy end use in Europe. Hybrid heating systems based on sustainable technologies such as cogeneration and heat pumps have the potential to increase energy efficiency and/or share of renewable energy in the energy supply for heat. In order to achieve these saving potential, hydronic integration is critical. To optimize the design of this integration, a simulation-based design methodology is proposed. The methodology is characterized by a Base Circuit approach, which is incorporated in the design and simulation software Hysopt. A representative, but simplified case study is implemented in the software to illustrate the optimization potential of hydronic integration for hybrid heating purposes. Differences in primary energy savings of up to 20 percentage points were reported, indicating the importance of hydronic optimization.
