- In the Desorber thermal energy is supplied to the system, and
the refrigerant separates from the absorbent.
- In the Condenser the refrigerant liquefies by heat transfer to
the heat output.
- In the Evaporator an evaporation process takes place, which
causes the cooling effect by heat transfer from the refrigeration
- In the Absorber the ammonia is absorbed again by the water and
the cycle can start anew.
