ABSTRACT:
An absorption refrigeration system includes an evaporator 1, an absorber 6, a regenerator 9, and a condenser 13. In the evaporator 1, water as a refrigerant is caused to evaporate by depriving a chill carrier fluid 4 of its heat. The water vapor 5 from the evaporator 1 is absorbed into an absorbent consisting of an aqueous lithium bromide solution in the absorber 6, heat being generated thereby. The regenerator 9 receives the diluted absorbent 7 from the absorber 6 and heat same with a heating fluid 11 to evaporate the absorbed water from the absorbent. The concentrated absorbent 10 resulting from the step of regeneration is returned to the absorber 6, while the water vapor 12 generated in the regenerator 9 is introduced into the condenser 13. A supply of condensing water 14 is sprayed into the condenser 13 for direct contact with the incoming water vapor 12 to condense the latter. A portion of the collected water 15 in the condenser 13 is transferred through piping 16 to the absorber 6, in which it is heated with the absorption heat generated therein. Another portion of the water 15 is supplied to the evaporator 1 through a branch line 2 having a pressure reducing valve 3 and is evaporated in the evaporator 1.
