The objective of this project is to design and build a mobile test bench for conducting airtightness tests on and inside buildings, supplemented by evaluation software to be developed in-house. The test bench is intended to enable the measurement of differential pressure and airflow, provide robust interfaces to sensors and actuators, and include a safe, mobile setup (power supply, cabling, protective housing).

On the software side, the project includes data acquisition, plausibility checks, visualization of measurement series, and automatic report generation; calibration and uncertainty estimates can be integrated as optional features. Individual components (e.g., hardware design only or software only) can also be addressed separately, depending on the specific focus.

The goal is a practical test bench with user-friendly evaluation.

This project is suitable for an internship or a bachelor’s thesis and is particularly appealing to students majoring in building services engineering, mechanical engineering, or related fields. A basic understanding of measurement technology and an interest in practical application are helpful; programming skills (e.g., Python) are desirable but not required—the necessary skills can be developed as part of the project.

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.).
