Decentralized push-pull ventilation units are equipped with so-called weather protection hoods on the outside. A cooling function is to be integrated into such a weather protection hood. The operating principle intended for this purpose is indirect evaporation. The resulting cooling potential is to be used to cool the warm outside air in the summer.    

The technical solutions under consideration for this purpose are leading to new designs for weather protection hoods. Special technical textiles are planned to serve as the water-carrying structure. These must be connected to a highly efficient heat transfer system. The technical fabrics are moistened with (soft) water. Depending on the outdoor air conditions, the water in this structure evaporates. The amount of evaporated water must be replenished accordingly.

For the technical requirements described above, model studies are to be developed and conducted, and design solutions for the heat exchanger system and water dosing are to be developed.

This project can be carried out as part of a student thesis. It requires basic knowledge in the fields of mechanics, thermal engineering, and fluid mechanics.

Since our internships and the supervision of student projects are primarily intended to provide practical experience and career guidance, we ask for your understanding that no compensation is provided. However, we would be happy to issue you a formal internship certificate and nominate your student project for the annual academic award presented by the Association for the Promotion of Air Conditioning and Refrigeration Technology (Verein zur Förderung der Luft- und Kältetechnik e.V.).
