There is a wide variety of alternating-flow, decentralized ventilation units. These units are very simple in design and consist of the following components: a wall-mounted sleeve, an interior cover, an axial fan, a heat accumulator, and a weatherproof hood. The axial fan is designed so that it can operate in both directions of rotation. When the direction of rotation changes, the fan changes the direction of airflow. These fans are very sensitive to pressure fluctuations (caused by wind).

The goal is to develop a new fan capable of changing the flow direction and air volume during operation by adjusting the blade angle. Changing the flow direction should no longer require a change in the direction of rotation. Additionally, the fan should be made more pressure-stable. This new development involves model testing, design studies, and the development of mechanical solutions for adjusting the blade angle.

This development can be carried out as part of a student thesis.

The task requires basic knowledge of fluid mechanics, mechanics, and 3D printing.

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.).
