General information on the Institute PI
Heat storage: Basics
• Supplied and required heat do not always match
• Increase of degree of utilization of technical plants in private
households, business and industry
• Development of innovative heat accumulators as latent heat
storage
• Sensitive storage energy supply results in temperature increase
• Latent heat storage energy supply results in phase change
without an increase in temperature until material is melted. Ideal
combination with heat pumps for temperatures of 27°C or 36°C.
Sample applications: Heat accumulators
• Institute director: Prof. Dr. rer. nat. Matthias Rädle
• 38 employees in total, 34 employees financed through third-party funds
• Institute 360 m² on university campus, 850 m² rented externally
• Third-party funds: approx. 3 Mio. € per year
• Since 2010 biggest institute of an university of applied sciences in Baden-Württemberg
