AWT - Investigation of two energy converters with low electrical energy requirements, in order to supply heat to consumers with high temperature demands, using low-temperature district heating network sources
District heating networks 4.0 have a maximum supply temperature up to 95 °C, which is relatively low. These networks are a fundamental part of the energy transformation process. The aim of this research project is to provide, in an efficient manner, a higher temperature flow, up to 120 °C, to certain consumers with such a requirement using District Heating Networks 4.0, despite its lower supply temperature capability. Two energy converters with low electrical power requirements, an absorption heat transformer and an absorption–compression heat pump, are being investigated for their suitability to increase the temperature in the district heating network in a decentralized, demand-oriented manner. -

A real-time communication shall be developed for the exchange of the relevant information used by both systems for a demand-orientated control. -
HoVAG
Large-scale heat pumps will play a central role in the climate-neutral heat supply to industry. However, the use of conventional refrigerants is in question due to regulatory requirements (F-Gas Regulation, impending PFAS ban). Future-proof alternatives are “natural refrigerants” such as ammonia. The HoVAG research project aims to develop shell and tube heat exchangers with new high-performance tubes optimized for the evaporation of ammonia. These enhanced heat exchangers will increase the efficiency of large-scale ammonia heat pumps, reducing the required refrigerant charge. -

In diesem Projekt wird ein neuartiges System entwickelt, das die gleichzeitige Sanierung von Gebäudehülle und Heizsystem ermöglicht, ohne größere Arbeiten im Inneren des Gebäudes zu verursachen. -
innoBeLs - Development and assessment of innovative container concepts for latent heat stores in cold solar heating networks
The aim of the "innoBeLs" project is the development and implementation of innovative economically and ecologically beneficial container concepts for latent heat storage for commercial use in solar cold district heating networks. Currently, latent heat or ice stores mainly use cost-intensive concrete tanks with two heat exchanger coil loops. Their production is relatively energy-intensive, leading to significant greenhouse gas emissions. In contrast, the newly developed innovative container concepts aim to reduce environmental impact and resource consumption by at least 50 % and cut costs by at least 20 %.
