Unser Kooperationswunsch im Detail

Background

Refrigeration systems have undergone an enormous growth rate on the market in past years with a growing demand for new and more efficient refrigeration systems. To increase the efficiency of energy use one way is to include cogeneration systems, as they provide a resource-saving way for using cold temperatures and do not additionally raise the power demand. Instead they utilize the waste heat from power production directly for refrigeration purposes. It is thus an object to provide improved  technologies in conjunction with cooling systems, with which the efficiency of such systems can be increased.

 

Technical Description

The invention comprises a way to optimize the cooling or refrigerating capacity in an evaporator device, i.e. the transfer of thermal energy from the fluid to be cooled to the cooling agent, by supplying external thermal energy provided by an external heat source to the cooling agent in the reservoir of the evaporator device. This external thermal energy is used to practically externally excite the cooling agent in the reservoir so as to induce bubble formation or amplify bubble formation already triggered by the cooling heat transfer. The latter can be the result of a so called pool-boiling process, which is initiated by the cooling heat transfer from the fluid to be cooled to the cooling agent in the reservoir with the cooling agent.

 

Potential Applications

The technology relates in particular to optimizing the vapor generation in evaporation processes for refrigeration in sorption cooling systems. Above all cooling systems in which the process takes place under a vacuum can benefit substantially from this, without there being any limitation to this application. In particular, the technologies can also be used in other refrigeration systems. In principle, use is possible in all applications in which a fluid is to evaporate in portions on a heat exchanger surface, thereby being present in two phases in its immediate proximity.

Technische Universität Berlin (Zentrum für geistiges Eigentum)

Das Präsidium der TU Berlin hat das Zentrum für geistiges Eigentum (ZfgE) mit dem Ziel ins Leben gerufen, den Technologietransfer an der TU Berlin zu vereinfachen und als zentrale Anlaufstelle für alle am Technologietransferprozess Beteiligten zu fungieren.

Im ZfgE werden die mit dem Technologietransfer zusammenhängende Gestaltung in der Praxis und die wissenschaftliche Auseinandersetzung mit Fragen des geistigen Eigentums unter einem Dach zusammengefasst. Darüber hinaus soll das ZfgE der zentrale Ort für Forschung, Lehre und Weiterbildung auf dem Gebiet des Immaterialgüterrechts werden.
