Abstract

Triple-effect absorption heat exchange apparatus for transferring heat from a heat load to a heat sink. The apparatus comprises first and second interconnected refrigerant loops. The first loop comprises a first generator, a first condenser, a first evaporator, and a first absorber operatively linked together. The second loop comprises a second generator, a second condenser, a second evaporator, and a second absorber operatively linked together. The first absorber and the first condenser are in direct heat exchange relation with the second generator. This direct heat exchange relation may be established by providing a two-stage generator in which the condenser and absorber of a first loop are in the same vessel as the generator of a second loop. The condenser and absorber of the first loop provide the heat necessary to operate the second-loop generator. The preferred generator comprises a first vessel divided by a partition into first and second chambers and at least one second vessel made of a heat-conductive media. The first and second vessels are in heat exchange contact across the medium. Each second vessel has an entrance and an exit, is unobstructed between its entrance and its exit, and passes through the first chambers vessels.
