The project “FlexKälte” (Joint project: Investigation of existing cooling systems in order to use flexibilities in a real world application; sub-project: Campus instrumentation for optimal cooling system control) has the aim to develop a methodology to make use of the flexibility of decentralized, cold producing and cold using plants existing in a property. Besides the identification of the flexibility potential, the “FlexKälte” project focuses on the demonstration of the practical feasibility of an efficient and economic operation of cooling in a real world application, while at the same time ensuring the identified boundary conditions, such as user comfort.

As part of the project, distributed refrigeration applications on the KIT North Campus are instrumented, connected and virtually combined for central control. First, the optimization strategies to be developed are tested with a large number of refrigeration systems in a simulation and then the practical implementation is implemented using an example. Through the desired central administration, the virtual network should serve as a cooling capacity / storage facility as a whole and thus - beyond an operational optimization - be able to react to changing supply network conditions.
