Absorption Refrigerator Working Principles
An electric heater is connected below the generator which heats it. Contained within the generator is a combination of water and ammonia that begins to boil. The boiling solution passes down a pipe to the separator, which by dint of the difference in water and ammonia's molecular weight, separates the two materials. Ammonia rises upward in the form of a gas while the water doesn't. As a result, the water heads to the absorber to wait for later use while the ammonia travels to the condenser. The condenser is an expansive device which allows the ammonia's heat to dissipate and the ammonia condenses back into a liquid. The ammonia is shunted to the evaporator, where it mixes with compressed hydrogen gas and evaporates once more into a freezing vapor. The vapor is pumped through the cooling coils within the fridge as a result of pressure initially created by the generator, which is still driving force for this entire process. Once the vapor passes through the coils, it travels to the absorber, which recombines with the water. A chemical reaction occurs, in which the ammonia combines with the water as a liquid, while the hydrogen gas travels up a pipe into the evaporator to wait for this repeated cycle. Likewise, the ammonia and water flows back down into the generator.
