PARALLEL FLOW
The lithium bromide solution flow type is a parallel
flow cycle. The flow of weak solution pumped from
the absorber initially passes through the low tempera-
ture solution heat exchanger. This improves the oper-
ating efficiency by preheating the weak solution. The
solution flow divides into two paths. One leads to the
high temperature generator through the high tempera-
ture solution heat exchanger. The other leads to the low
temperature generator in parallel.

HIGH TEMPERATURE GENERATOR (HTG)
The high temperature generator section is a flooded,
smoke tube design. The exhaust gas passes through the
tubes. As it does, it heats the pre-heated dilute solution
from the high temperature heat exchanger.
The hot refrigerant vapor boiled off from the dilute
solution is sent to the low temperature generator. The
strong solution left behind is returned to the high tem-
perature heat exchanger.
