Test benches for components and system technology

We investigate the interaction of components in the system. To this end, hardware-in-the-loop test benches are set up and energy systems are analyzed, ranging from subsystems to complete energy systems for apartment buildings.

The interaction of the physically installed components is examined, optimized and evaluated for realistic dynamic operation. To do this, we use characteristic load profiles and type days, which are provided by means of source and load emulation. The central aspect is less the optimization of individual components than the optimization and evaluation of the interaction of components in complex building energy systems. Algorithms for energy centers and installation recommendations are derived from the investigations.
