Johnson Controls York YHAU-C - Solution Heat Exchanger; Generator

Solution heat exchanger
The dilute (weak) LiBr solution leaving the lower absorber section is pumped to the generator
section through a solution to solution heat exchanger. It is preheated before entering the
generator section. Such preheating of the dilute solution reduces the driving heat source
requirement in the generator and also helps to cool down the concentrated (strong) solution
before entering the upper absorber section.
Generator
The generator is a falling film design. The steam passes through the stainless steel tubes. There it
heats the preheated dilute solution from the solution heat exchanger and the steam drain cooler.
The refrigerant (water) vapors migrate to the condenser, leaving behind a concentrated (strong)
LiBr solution that is then cooled before being distributed in the upper absorber section.
