How absorption cooling works

A concentrated ammonia solution is heated in a boiler and driven off as vapour. The pressurised ammonia gas is then liquefied in a condenser. Supplied with hydrogen, it evaporates and extracts heat from the storage container. The ammonia gas then enters the absorber where it is reabsorbed in a weak solution of ammonia. Finally, the saturated solution flows back to the boiler where the whole cycle starts again.

Day to Day Use

Absorption fridges are relatively lightweight and easily moved as operational requirements dictate. Care should be taken when moving units that they are not subjected to sudden impacts. Also the new location must meet the ventilation and levelling requirements described above. If the unit is laid on its side or front (never on its back) during moving, then it must be stored in the upright position for 24 hours before being returned to service.
