After absorbing the moisture in the absorber, the weak desiccant solution needs to be regenerated. Fig.2 shows a schematic diagram of a regenerator. The device consists of flat plate containing internal channels assembled in

parallel. The regenerating fluid (i.e. water) flows through
these channels and transfers heat thought the plate wall to
the desiccant solution which is in direct contact with the
air. The desiccant solution flows downwards and is
spread over a thin porous medium, while the air flows
upwards in the passages between the plates. Some of
water contained in the desiccant solution evaporates and
is absorbed by the air flowing upwards.
