Transformation of the Energy System in Lower Saxony (TEN.efzn) – Heat

The research platform Heat deals with studies about central questions regarding the innovative heat pump technology for general heat supply. Within the framework of two innovation areas, significantly different requirements are placed on this technology. An important aspect is the model-based development of heat pump concepts, which are validated and tested through experimental studies and demonstrators.

The aim of this project is to use an interdisciplinary procedure to develop complete solution approaches, which are suitable for technical, economic and ecological requirements. A special focus is set on the cooperation with associated partners from the industry and economy in Lower Saxony in order to create applicable and economical heat pump solutions. Social aspects are also conducted in order to rise the acceptance of this technology and anchor it in society.

The ISFH is involved in the innovation sectors of High-Temperature Large-Scale Heat Pump and Heat Pump Technology for Building Supply.

In the sector High-Temperature Large-Scale Heat Pump a modular test rig is being set up at ISFH to investigate different working fluid mixtures and various compression circuit processes in order to validate and optimize the developed heat pump models. Subsequently, the requirements of a local, industrially associated partner are analyzed in order to develop a concept for the construction of a high temperature large-scale heat pump. The implementation of the concept will be initiated at the end of the project.

In the sector Heat Pump Technology for Heat Supply of Buildings an AI-based method for  system analysis, operation optimization and error detection is being developed and researched at ISFH. This method is going to be experimentally tested and improved on a test rig with compact heat pump modules on the base of user input and training data.
