Heat Conversion - HCV -

The Heat Conversion group researches and further develops the field of heat conversion via chillers and heat pumps. Its range of research extends from the development and optimisation of individual components to their integration into complex energy systems. Many years of expertise have accumulated in the group, particularly on sorption heat pump and cooling systems (closed absorption, open adsorption), sorption storage systems, and innovative compression refrigeration applications.

The main work focuses are:

  • Research on thermal fluid dynamics, heat transfer, and fluid process engineering
  • Heat pump cycle design, optimised circuits, methods for increasing efficiency
  • Design, construction, and testing of thermally or electrically driven chillers and heat pumps
  • Identification of promising applications for innovative heat pump solutions and adaptation or adapted development of such
  • Planning and integration of innovative heat pump solutions into complex energy systems, including operational support and optimisation
  • Design of plants and energy systems for cooling and heating in the fields of trigeneration, solar air conditioning, waste heat utilisation, cooling with biomass, and cooling with district heat
