Software
On this page we offer you software developed at ISFH for download.
DHGpy (free of charge, see license)
DHGpy is a tool based on Pandapipes that enables the design and thermal-hydraulic simulation of district heating networks, with a current focus on "cold district heating" (5th generation of district heating).
This is currently only the first executable version with a workflow with csv files and QGIS.
TRNSYS Types (free of charge after license agreement)
ISFH - Components for thermal plant simulation with TRNSYS
ISFH has developed a series of components for the simulation of thermal and electrical equipment for the TRNSYS simulation environment. We provide a selection of the created types free of charge.
How do I get such a type? Please download the respective license agreement and fax it completed with your e-mail address to 05151-999-500 or send it to s.ringe@isfh.de. We will then email you the type.

SEGA GUI (free of charge after license agreement)
In research into industrial silicon solar cells, the gap to the theoretical efficiency limit of around 29% is gradually closing.
Closing this gap further is a challenging task for cell developers. The identification of the most promising cell properties for the further research is an important aspect of the development process. The SEGA-GUI, which can be downloaded below, addresses this task by enabling researchers to perform synergistic efficiency gain analyses (SEGA) without any programming knowledge and on short timescales. Here the solar cell is simulated one time with the parameter as in a reference simulation and one time with the parameter idealized.
The difference of the energy conversion efficiencies is the improvement potential due to this parameter. This approach also enables the analysis of synergistic effects between different loss channels. Also partly deactivated loss channels can be analyzed. The input required for performing a SEGA is a set of easily measurable cell properties including resistances and recombination currents. The optical properties of the cell can be determined from a measured reflectance spectrum.
