We are seeking a highly motivated researcher to join an interdisciplinary project focused on the development and demonstration of a thermally driven adsorptive cooling storage unit as a mobile refrigeration solution. The aim is to design a compact, lightweight, and robust cooling unit based on the natural refrigerant water, suitable for the transport of temperature­sensitive goods such as food, organs, or vaccines. The system utilizes various renewable energy sources including solar thermal energy, waste heat, and surplus renewable electricity, and stores the recovered heat thermochemically, allowing for later, power-free, and environmentally friendly cooling in both stationary and mobile applications.

The TU Berlin contributes to all stages of the development process from Simulation to prototype construction. The university is responsible for the model-based design and simulation of the adsorption cooling unit, supports the evaluation of suitable sorption materials and heat exchanger concepts, and collaborates with an industrial partner on the design and construction of the prototype. A test bench will be established at TU Berlin for measurement and validation of the prototype. The project is carried out in close cooperation with two industrial partners based in Berlin. lt is intended that the developed components will be further developed, manufactured, and eventually commercialized or licensed by the industrial partners.

• adaptation of existing simulations from the previous project
• assessment of design options and estimation of performance limits under varying boundary conditions
• validation and improvement of simulation models based on experimental data
• support of construction activities at the test bench and assistance during prototype measurements
• supervision of student assistants and thesis projects within the scope of the research project
• dissemination of project results through publications and presentations at international conferences
• contribution to project management and organization of project meetings

• successfully completed university degree (Diploma, Master or equivalent) in Energy or Process Engineering, Engineering Science, or a closely related field
• sound understanding of heat transfer, sorption technology, and refrigeration systems; demonstrated through relevant coursework, project work, or professional experience
• experience in steady-state and dynamic modelling of system components such as heat exchangers and piping
• proficiency in data processing, analysis, and visualization tools, and basic programming skills, e.g. in Python or Matlab
• good command of German and/or English, with willingness to acquire the missing language skills
• demonstrated experience in academic or collaborative research projects (is desirable)
• structured, independent working style and ability to work in a team (is desirable)
• friendly and clear communication skills (is desirable)

• participation in a practical, interdisciplinary research project on sustainable and mobile cooling technologies with strong industrial relevance
• integration into a research group with long-standing expertise in sorption and compression technologies
• opportunity to pursue a PhD within the scope of the research project
• flexible working hours and a modern research environment with access to well­equipped laboratory and workshop facilities
