Final answer:
In an absorption refrigeration system, the low side components are the absorber and the evaporator, where heat is absorbed and the refrigerant evaporates at low pressure.
Step-by-step explanation:
The parts of an absorption refrigeration system on the low side are the absorber and the evaporator. In an absorption refrigeration system, the evaporator is where the refrigerant absorbs heat and evaporates, turning from liquid to gas at low pressure and temperature. The refrigerant then moves to the absorber where it is absorbed by a secondary fluid, continuing its cycle at low pressure. Other components such as the generator and the condenser are on the high side of the system. The generator's role is to separate the refrigerant from the absorbent solution, while the condenser's function is to convert gaseous refrigerant back into liquid form, releasing the absorbed heat into the surroundings.
