Open-source modeling libraries facilitate the standardization and harmonization of model development. In the context of building energy systems, Modelica is a suitable modeling language as it is equation-based and object-oriented. As an outcome of the IBPSA project 1 cooperation, four open-source modeling libraries have been successfully deployed w...

Back-up heaters are essential for sustainable retrofit heat pump systems to achieve low capital costs and high system temperatures. Despite its importance, current literature focuses primarily on single aspects of the interaction between the back-up heater and the heat pump system. Furthermore, influences of varying scenarios are typically not cons...

Zusammenfassung Aufgrund des russischen Angriffs auf die Ukraine ist mit einer deutlichen Verknappung und weiteren Verteuerung des Erdgases in Deutsch-land zu rechnen. Neben der Industrie und dem Bereich Gewerbe, Handel und Dienstleistungen können die privaten Haushalte erhebliche Einsparungen im Gasverbrauch für Raumwärme und Trinkwarmwasser durch...
Article
Vapor compression cycles have gained high importance due to increasing concerns regarding the decarbonization of heating and cooling applications. Typically, vapor compression cycles operate under dynamic conditions, making it difficult to predict their performance accurately. Dynamic simulation models present a decent solution for increasing the r...
Article
Aiming for a sustainable building stock, air-source heat pump systems are a key technology. In residential application, heat pump systems typically consist of a heat pump, an auxiliary heater, two thermal storages (for space heating and domestic hot water), and a system controller. Compared to conventional technologies, the efficiency of a heat pum...
Conference Paper
Conventional design methods oversize heat pump systems to ensure heat supply coverage. Oversizing might lead to efficiency losses due to part load operation and to high investment cost. To overcome those issues already in the design process, decisions on refrigerant, heat pump and system level must be made simultaneously. Based on process intensifi...

Die Defossilisierung der Gebäudeenergieversorgung durch die Integration erneuerbarer Energiequellen erfordert eine ganzheitliche Betrachtung der Versorgungssysteme, um deren Einbindung zuverlässig bewerten zu können. Zur zuverlässigen Bewertung und maximalen Ausschöpfung des ökologischen und ökonomischen Einsparpotentials der vornehmlich volatilen...
Poster
Heat pump systems are a key technology to replace conventional heating technologies such as gas-fired boilers towards a sustainable building sector. Especially in existing buildings, heat pump systems commonly consist of an air-source heat pump, an auxiliary heater and thermal energy storages. Compared to an almost constant energy efficiency of boi...

Um die Attraktivität der Wärmepumpe für die Anwendung in der Gebäudenachrüstung steigern zu können, ist eine verstärkte Betrachtung aller Ebenen des Wärmepumpensystems notwendig. Dabei haben verschiedene Faktoren unterschiedlichen Einfluss auf die Gesamteffizienz des Systems. https://www.tab.de/artikel/tab_Integrierte_Auslegung_3620539.html
Conference Paper
Der Einsatz von Wärmepumpen forciert eine nachhaltige Wärmeversorgung des Gebäudesektors, da zukünf-tig mit Strom und Umweltwärme ressourcenschonende Energiequellen eingesetzt werden können. Aller-dings ist die Marktdurchdringung der Wärmepumpe durch hohe Investitionen gehindert. Konventionelle Auslegungen führen zu einer Überdimensionierung der Wä...

We aim to reduce the commissioning costs of building energy systems by using agent-based control concepts. For this purpose, the autonomous agents try to find efficient solutions for the energy supply of the building by negotiating the distribution of resources with other agents.
