Refrigeration and heat pumps (MA-RPR-1-e)

During the Cooling subject we want to provide students useful knowledge in the field of food refrigeration, HVAC, as well as industry refrigeration. The main objective of the course is to educate students in order to select the correct cooling process according to the specific application so that we always achieve the highest energy efficiency and the least environmental impact. During the course, students will acquire theoretical as well as practical knowledge in the field of sizing, vapor-compression cooling cycles. Besides, students will learn the difference between the theoretical and real cooling process, the importance of overheating, subcooling and heat regeneration within the cooling cycle and gas cooling process. Particular attention will be paid to refrigerants, their specific requirements, energy and environmental considerations. Emphasis will also be placed on alternative refrigeration technologies to increase the primary energy use, such as trigeneration systems and absorption refrigeration. Students will also learn about several alternative cooling systems, such as: solid-state physics-based cooling and caloric cooling systems. Usefulness of the knowledge gained during the Cooling course will be completed by demonstrating possible measures for the use of condensing heat, which makes the operation of the refrigerator equivalent to that of a heat pump.
