Abstract:
A triple-effect absorption refrigeration system, comprising:an evaporator;an absorber operatively coupled to the evaporator;first, second, and third generators connected to receive a solution originating from the absorber and flowing to the first, second, and third generators;a heat source for heating the solution in the third generator to a temperature, thereby separating the solution in the third generator into a strong refrigerant-absorption solution and a refrigerant vapor;a flowpath for returning the strong refrigerant-absorption solution from the third generator to the absorber;first, second, and third condensers operatively connected to receive and condense refrigerant vapor from the first, second, and third generators, respectively, the third condenser operatively connected to exchange heat with the second generator, and the second condenser operatively connected to exchange heat with the first generator; anda heat exchanger operatively connected to exchange heat between the condensed refrigerant vapor from the third condenser and the solution flowing directly to the second generator, but not directly to the third generator.
