Abstract
In a triple effect absorption refrigeration system, solution flows from an absorber to first and second generators connected in parallel. Solution exiting the first generator returns to the absorber. Solution exiting the second generator flows to a third generator connected in series with the second generator. Refrigerant vapor from each generator is condensed in a respective condenser. The third condenser exchanges heat with the second generator, and the second condenser exchanges heat with the first generator.
Claims17
A triple-effect absorption refrigeration system comprising:
- an evaporator;
- an absorber operatively coupled to said evaporator;
- first, second, and third generators, said first and second generators connected in parallel with said absorber to receive a solution in a parallel first flowpath from said absorber, and said third generator connected in series with said second generator to receive the solution in a second flowpath from said second generator;
- a heat source for heating the solution in said third generator to a first temperature, thereby separating the solution in said third generator into a refrigerant vapor and an absorption liquid;
- a third flowpath for returning the absorption liquid from said third generator to said absorber;
- and
- first, second, and third condensers operatively connected to receive and condense refrigerant vapor from said first, second and third generators, respectively, said third condenser operatively connected to exchange heat with said second generator, and said second condenser operatively connected to exchange heat with said first generator.
