Introducing students to heat pumps as low-carbon technology to achieve energy neutrality. The emphasis is on the acquisition of practical knowledge and laboratory work that will provide students with a broader picture of the application of heat pumps. Through several systems implemented at the FSB, students will have the opportunity to get acquainted with the components and control of the system and monitor the effects of process parameters on system efficiency.

Student responsibilities:

Regular attendance of lectures and exercises, as well as regular homework and seminars completion

Grading and evaluation of student work over the course of instruction and at a final exam:

Appropriate attendance of classes (both, lectures and exercises) and student"s feedback will constitute 25% of the final mark, while the outcome of the oral and written exam will account for the rest (40% + 35%).

Upon successful completion of the course, students will be able to (learning outcomes):

1 . Recognize the potential of heat pumps as low-carbon technologies for decarbonization of different energy sectors

2 . Apply optimal heat source for observed heat pump system

3 . Size basic heat pump components and design P&ID diagrams

4 . Recognize potential of industrial waste heat for high temperature heat pump application

5 . Conduct technical and economical comparison of heat pump and conventional systems
