Cooler with Absorption System

It is the one that uses heat energy rather than mechanical energy to complete the refrigeration circuit.
In the absorption system the compressor is replaced by a heater ie a heat generator.

The main sources of energy are:
Kerosene.
Cooking gas (LPG).
Eletric heater.

The refrigerant solution in the absorption system is composed of three elements:
Distilled water - heat absorbing.
Ammonia (NH3) - refrigerant.
Sodium chromate - anticorrosive.

The absorption system has four components:
Heater or heat generator.
Condenser.
Absorber.
Evaporator.
