Abstract:
In a process and apparatus of conditioning an airstream, the airstream is contacted with a liquid desiccant absorber in each of at least two stages. The same apparatus used as an evaporator to reconcentrate the desiccant. The desiccant for each said stage is cooled or heated externally to the absorber or evaporator using an external source of cooling supplied with a common cooling or heating fluid at each stage. The desiccant flows between the stages counter-current to the flow of the airstream such that at each step the concentration of the desiccant is reduced or increased by contact with the airstream so that the concentration in each stage is distinct from the concentration of the desiccant in the previous stages.

Claim (Index 15):
An apparatus for exchange of heat and moisture between an airstream forced through the apparatus, an external energy fluid source, and a liquid desiccant flow that comprises:\n at least two separate but connected modules that are essentially identical, each module comprising:\n an absorber/evaporator for contacting liquid desiccant with air, \n a liquid desiccant distributor for distributing liquid desiccant over the absorber/evaporator, \n a heat exchanger external to the absorber/evaporator to cool/heat the liquid desiccant with fluid from the external energy fluid source, \n a pump operative to recirculate the liquid desiccant between the absorber/evaporator and the heat exchanger; \n an outer shell to direct the airstream through the absorber/evaporator; and \n a sump below the absorber/evaporator to collect the liquid desiccant distributed over the absorber/evaporator.
