ABSTRACT:
Apparatus for dehumidifying air is disclosed. The apparatus comprises first and second dehumidifiers, both of which employ a desiccant. Air to be dehumidified is passed through the first dehumdifier, then through the second dehumidifer, and from the second dehumidifier to a space to be conditioned. The desiccants of the two dehumidifiers remove moisture from the air so that it is dehumidified before it reaches the space. The apparatus also includes a first regenerator for the desiccant of the first dehumidifier, and a second regenerator for the desiccant of the second dehumidifier. Air is passed to and through each of the regenerators in contact with the desiccant therein and is then discharged. Heat of sorption is transferred from the two dehumidifiers, and moisture laden desiccant is moved from each of the dehumidifiers to its regenerator; finally, heat is transferred to each of the regenerators, and the heat transferred to the first regenerator includes heat of sorption from the first dehumidifier. Absorbed moisture is rejected from the regenerators.
