| Learning Outcomes of the Course Unit |
|---|
Students gain knowledge about with refrigeration technique and heat pumps. Students gain
deep knowledges in theory and design of compressor and sorption refrigeration
cycles and systems, environmental aspects of refrigerants. Further the use of
heat pumps for low potential heat utilization is taught.
It can be individually focused on particular topics by student's specialization. |
