Task
In industrial applications, ammonia is used efficiently as a natural refrigerant. Ammonia evaporators are typically operated in a flooded mode. This means that, unlike in most other refrigeration systems, the ammonia is not completely vaporized within the heat exchanger. This has a positive impact on the system’s efficiency. However, it makes the design of such evaporators/heat exchangers particularly challenging. The aim of this thesis is to further develop a design and calculation tool for such heat exchangers.
Qualifications
Knowledge of thermodynamics and design
Notes
The main division of refrigeration and heat pump technology at ILK Dresden focuses on cold vapor processes. To this end, individual components (compressors, heat exchangers, valves) are measured and further developed. In addition, processes and system configurations are also investigated. The results are intended to help cooperating industrial companies improve their products. These projects can be supported as part of student work. The topics presented below only provide a rough outline of the tasks. Depending on the type of student work (internship, coursework, thesis, etc.), the assignment will be individually tailored and adapted.
