Theoretical Basics of Heat Pumps (1 ECTS)

Learning outcomes

• The student understands the operating principle of a heat pump and can illustrate the operation of the refrigerant circuit in the refrigerant log p,h-diagram, determining from the diagram the heat pump's coefficient of performance, refrigerant superheating, and subcooling.
• The student can calculate the thermal energy produced by free energy using the coefficient of performance, as well as the thermal power taken from the heat source.
