The moisture in the desiccant solution is released to
the air stream as a result of heating the solution. In the
regenerator under investigation, the hot water used to heat
the solution can be heated either by solar energy or waste
heat from another process.
B. Experimental Setup
The regenerator is tested in a specially designed
experimental rig as shown in Fig. 3. The liquid desiccant
stored in the weak solution tank flows to the solution
distributor and then passes through to the upper part of
the regenerator. The concentrated solution leaves the
regenerator at the bottom part and is stored in a second
tank. The regeneration air, after being brought to the
desired temperature and humidity, flows from the lower
part through the upper part of regenerator then exits the
system. Hot water is pumped through the internal
channels of the regenerator in a cross flow direction with
respect to the flows of the desiccant solution and the air.
