An absorption chiller having a generator absorber heat exchanger with a split device for directing a first portion of strong solution from the absorber to the generator at a first temperature, while simultaneously directing a second portion of strong solution from the absorber to the generator at a second temperature. The absorption chiller operates to transfer weak solution from the generator to the absorber at a temperature of about 265.degree. F., while transferring strong solution from the absorber to the generator at two different temperatures--preferably about 210.degree. F. and about 240.degree. F.

Generator absorber heat exchanger for an ammonia/water absorption

This invention relates to a cooling and heating system which operates on the absorption and phase change heat exchange principle. More particularly it relates to a continuous heat actuated, air cooled, double effect generator cycle, absorption system. In further aspects, this invention relates to a system constructed for use with an absorption refrigeration solution pair consisting of a nonvolatile absorbent and a highly volatile refrigerant which is highly soluble in the absorbent. A disclosed refrigerant pair are ammonia as the refrigerant and sodium thiocyanate as the absorbent. An absorption cycle is disclosed using the thermo physical properties of sodium thiocyanate/ammonia, absorption/refrigerant pair. Also disclosed is the construction and configuration of a reverse cycle air cooled double effect generator absorption refrigeration system for use with the sodium thiocyanate/ammonia refrigeration pair, as well as subcompositions, subsystems and components that improve the system efficiency and reduce cost.
