Number: MER0003ONF In Group Research & Mercedes-Benz Cars Development (RD), we design the automotive generations of the future. We mean innovative products with the highest quality and efficient development processes. We are already working on vehicles that will secure the technology leadership of Mercedes-Benz in the future. The air conditioning of battery-electric vehicles (BEVs) is a very large secondary consumer: As a result, the range decreases significantly, especially in winter operation. A possible technology to reduce this effect is the dehumidification of the passenger compartment. Without the risk of windshield fitting, the circulating air fraction could be increased and the higher air temperatures thus saved the heating power. Particularly organometallic framework compounds (MOFs) are suitable for dehumidification. These have the property of being able to absorb more steam at room temperature than at higher temperatures. For the dehumidification operation, circulating air would flow over the material and be dried in the first step. It would then have to be discharged again by heating, the steam being discharged to the ambient air. The potential of dehumidification with MOFs is to be measured using a test bench in the vehicle environment. In addition to technical questions, questions in the context of cabin dehumidification and air conditioning are also to be examined using CFD and therm. comfort simulations. A test stand for dehumidification with MOFs has already been constructed prototypically from previous internal activities. Within the framework of the work, this test bench is now to be used and expanded to investigate the potential of dehumidification of the passenger compartment. These challenges come to you: Introduction to the subject of metal-organic framework connections (MOFs) by means of relevant literature, internal documentation, etc. Introduction to the functioning of the existing test stand and the existing measurement software Integration of further dehumidification components of other design into the test bench Development of an experimental plan for quantifying the dehumidification dynamics of different dehumidification components Test preparation and implementation at the test bench in the vehicle environment and in the climate chamber or in the climate wind tunnel Processing and analysis of the generated measurement data, as well as interpretation of the measurement results with regard to the use for vehicle air conditioning deriving further improvement/revision potentials for the existing test bench, especially with regard to increased dynamics and reduced package design incorporation into the existing CFD simulation processes and software, as well as into modeling Implementation and evaluation of CFD simulations, as well as the interpretation of the results produced Documentation of work results with a view to possible further research steps This student work offers a unique opportunity to investigate an early, innovative technology in the vehicle environment and to drive the path of this technology towards practicality and concept. The work student activity can start from August 2025.
