Future Cooling Solutions
In the context of industrial manufacturing processes as well as various other procedures often very high temperatures are needed. The resulting waste heat must be exhausted in some form, which regularly takes place via delivery to the surrounding without further use of the inherent energy.
Beyond that often a cooling is within defined manufacturing process steps, necessary from plants, components or closed area etc. Furthermore, there is often demand for cooling within defined manufacturing processes, plants, components or enclosed areas etc.
In the context of operating own power stations, likewise high temperature waste heat emerges, with the need for exhaustion.
The adsorption process presented here uses the developing waste heat and makes the following functions available:
Transformation of the waste heat energy in cold or heat at the same time or another as well as at the same place or another Storage of the waste heat energy Supply of cold e.g. for the cooling of plants, components, tools, buildings etc. _ Supply of useable heat e.g. for the heating, warm water preparation or preliminary heating of media in the context of the manufacturing
It creates further a basis for the pipeline-independent distribution of cold and warmth.

Entwicklung hochpräziser ab initio Potentiale für molekulare Simulationen thermodynamischer Eigenschaften ingenieurrelevanter Flüssigkeiten.
Zur Bestimmung der thermodynamischen Eigenschaften in Bereichen hoher Dichten und Temperaturen oder bei der Untersuchung der Stoffdaten von giftigen, explosiven oderkorrosiven Stoffen mit Hilfe molekularer Simulationen werden zur Beschreibung der Wechselwirkungen zwischen Atomen bzw. Molekülen effektive Paarpotentiale verwendet. Die Güte solcherPotentiale ist stark vom Modell und von der Qualität der für die Anpassung der Potentialparameter verwendeten experimentellen Daten abhängig; ihre Extrapolationsfähigkeiten auf extreme Zustandsbereiche sind kritisch zu bewerten. Die Anwendung quantenchemischer Rechenverfahren ermöglicht einen alternativen Ansatz, wobei Wechselwirkungsenergien ohne Nutzung von experimentellen Daten, d.h. ab initio, berechnet werden können. Die daraus gewonnenen hochpräzisen Potentialfunktionen ermöglichen, die thermodynamischen Eigenschaften mit hoher Genauigkeit und in einem breiten Temperaturbereich zu berechnen. Im Rahmen dieser Arbeitergeben sich folgende Schwerpunkte:Entwicklung hochgenauer Paarpotentialfunktionen für die Beschreibung der Paarwechselwirkungen auf Basis quantenchemischen ab initio Verfahren Berücksichtigung der Mehrkörperwechselwirkungen in Form von nichtadditiven Potentialbeiträgen Berechnung des zweiten bis siebten Virialkoeffizienten für die Erstellung thermischer Zustandsgleichungen unter Verwendung hochpräziser Potentialfunktionen Berechnung der Transporteigenschaften mittels der kinetischen Gastheorie Implementierung der ab initio Potentiale in Vielteilchensimulationen (Molekulardynamik und Monte-Carlo-Methode)Weiter ForschungsgebieteTechnische Thermodynamik, Wärme- und Stoffübertragung Physikalische und Quantenchemie, statistische Thermodynamik Klima- und Kältetechnik Experimentelle Thermophysik.
