  • Patent number: 4009575
    Abstract: A method, and apparatus for implementing the method, for simultaneously generating electrical power and producing refrigeration, utlizing an absorption/regeneration power cycle, and performing useful work with the heat rejected from the cycle. In the cycle, a working fluid is absorbed by a carrier fluid by an exothermic chemical reaction wherein the heat released is utilized to perform useful work. After absorption, the original fluids are regenerated by an endothermic chemical reaction with the required energy supplied by an external prime source. Surplus energy stored in the fluids after regeneration is extracted and utilized to generate electrical power, produce refrigeration, and provide internally required energy.
