TIL Update: Hot water storage

Our TIL library for thermodynamic systems is under continuous development. It is compatible with the latest version of the Modelica Standard Library 4.0.0 and has been supplemented with an add-on for hot water tanks, among other improvements. Get a trial license to model and simulate the provision of hot water in buildings for heating and domestic hot water.

Meet the Team: Yann Pellny

Yann is studying mechanical engineering at RWTH Aachen University, and we are pleased that he is writing his master's thesis on "The dynamic modeling of a methanol synthesis" with us. For modeling and simulation, he will use our process system library PSL, which we are constantly developing. Yann has French roots and therefore speaks both French and German fluently. A good opportunity for all French speakers to get in touch. 😉

Our clients

"In our research projects, we perform dynamic simulations and optimizations. We work with different operating systems (e.g. Windows, Linux) and often have very specific requirements for the software interfaces. Here, the communication with TLK Energy was always very good: software interfaces were adapted for us in a short time and questions were answered competently."

Mirko Engelpracht

RWTH Aachen University

"From formulating the task in the proposal phase to the completion of the project, we felt very well looked after. Technical depth was achieved very early on in the close-knit status meetings, which brought interesting discussions and knowledge gains for us. It's wonderful that projects like these exist."

Dr.-Ing. Rüdiger Noack


"The collaboration with TLK Energy was very straightforward and always solution-oriented. Together we have created a web-based ventilation simulator that helps us to communicate the benefits of our Airflow products better.“

Simon Morherr

AIRFLOW Lufttechnik GmbH

“TLK Energy has been instrumental in developing modeling tools that allow TNO to advance innovative heating and drying solutions for the industry. We appreciate the open communication and the fact the TLK Energy team consistently exceeds our expectations.”
