The vapour absorption refrigeration system consists of:
· Absorber: Absorption of refrigerant vapour by a suitable absorbent or adsorbent, forming a strong or rich solution of the refrigerant in the absorbent/ adsorbent.
· Pump: Pumping of the rich solution and raising its pressure to the pressure of the condenser.
· Generator: Distillation of the vapour from the rich solution leaving the poor solution for Recycling
