Real-time control and tuning of borehole heat exchanger fields for optimal integration in heating and cooling systems
RECOIN
Call 2 2019
Borehole heat exchanger (BHE) fields combine many individual BHEs for the comprehensive supply and storage of heat and cold. In the RECOIN project, a new type of control system is being developed that monitors the thus far largely uncontrolled operation of such fields, smartly regulates individual BHEs and adapts them for optimal overall system efficiency.
The project's most important development is flexible modelling, prediction, and control procedures that will be integrated into a new predictive control system. In the international consortium, the focus is on constructing a real-time controller and validating the control system, which is applied as a prototype to a highly monitored field site in Switzerland. In cooperation, also through application to other fields in Berlin and Stockholm, the basis for flexible, practical use and utilisation is created.
