Solar Thermal Design

The course is project based, and the work is done in groups. The course starts with lectures on solar thermal systems, hydraulic components and their function. The system function and the control functions and their integration into existing heating systems are further discussed. Students are introduced to a case study (project). Students will calculate the load for the case and size the system. The next step is to learn about the simulation program Polysun. Students will get a template system in Polysun to modify and to further study the system performance of the case study. By using parametric studies the students optimize the size and dimensions of the system. Finally the student will write discussions and conclusions with reflections on the project work. Here the decisions made during the design process are debated and the assumptions and limitations in the simulation tool and methods are discussed.
