Absorption process in refrigeration and system

a system of refrigeration, depending upon the remarkable affinity of ammonia for water.aqua amonia for water.aqua amonia is subjected to the heat of a steam coil in a boiler or generator , the amonia gas immediately dissociating from the water , and , after passing through vessel termed the analyzer and rectifier , designed to separate all watery particles ,it is liquefied,still under pressure,in a surface condenser,from the liquifier it escapes through a regulating valve into the coils or manifolds of the refrigerator wherein is little pressure, and the aging expands into gas , taking the heat necessary for this change from the contents of the refrigerator, be it air ,water or brine ,thus chilling or freezing them . After performing its work in the refrigerator or ice tank , the ammonia gas is led into the absorber , where it is mingled again with the poor liquor from which it was originally evaporated, and finally pumped back into the genrator to be used over again. Absorption system of refrigeration: A system of refrigeration whose working principle may be stated as the alternate repultion and absorption of amonia gas by the alternate heating and cooling of amonia water . The essential parts of the system the system are: 1. Genrator 2. Condenser 3. Expansion coils 4. Absorber 5. Pump 6. Exchanger or inter cooler
