2.4 Concept of operation
A heat pump (HP) is a thermodynamic machine which transfers
heat from one location to another. To do so, it employs the
characteristics of a refrigerant fl uid.
The system is composed of the following circuits:
- The refrigeration circuit which transfers heat to the water
circuit following the evaporation, compression, condensation
and expansion of the fl uid.
- The heating circuit.
