Abstract
A hermetic shell of an absorption refrigeration apparatus contains an internally mounted heat exchanger that minimizes external piping. The internally mounted heat exchanger provides a means for exchanging two solutions having unequal portions of lithium bromide and water between a generator and an absorber, both of which are also contained within the shell. The solution having the higher concentration of lithium bromide leaves the generator and preheats the incoming dilute solution as the two solutions pass through the heat exchanger. The heat exchanger is located adjacent to both the generator and the absorber so that the concentrated solution can be conveyed internally through the shell from the generator to the absorber without relying on external piping.
