Fraunhofer ISE places particular emphasis on the development of new materials for latent heat and cold storage and has an extensive R&D infrastructure and many years of experience in this field. The main aim of our research is to increase the storage density and long-term stability of storage materials. In addition to latent heat storage materials, we also develop and optimize sorption materials.
Our services include:
- Material screening of heat storage materials, especially PCM and sorption materials
- Development of formulations for the production of PCM emulsions (PCM slurries) on a liter scale
- Upscaling the production of PCM emulsions up to the cubic meter scale
- Microencapsulation of PCM
- Thermal stabilization of PCM
- Rheological characterization of heat transfer fluids and PCM
- Determination of the specific heat capacity of materials
- Determination of the heat of fusion and phase transition temperatures of phase change materials
- Determination of the thermal conductivity of storage materials
- Long-term stability studies of PCM and PCM composite materials
- Determination of the crystal structure (XRD), phase analysis and conversion of sorption materials
- Determination of reaction enthalpy and heat capacity by differential calorimetry of sorption storage tanks
- Testing and characterization of PCM and PCM composite materials for the RAL-PCM quality seal
