The high-temperature generator pump draws a portion of the intermediate solution from the low-temperature generator and delivers it to the high- temperature generator to be reconcentrated.

This cooler intermediate solution passes through the high-temperature heat exchanger to be preheated by the hot concentrated solution returning from the high-temperature generator. This reduces the heat energy required to boil the refrigerant inside the high-temperature generator. Precooling the concentrated solution returning to the absorber reduces the flow rate of cooling water required through the absorber.

The precooled, concentrated solution leaving the high-temperature heat exchanger then mixes with the rest of the intermediate solution that is returning from the low-temperature generator, before traveling to the low-temperature heat exchanger.
