Abstract: Apparatus for conditioning air comprising: a quantity of liquid desiccant (28); a dehumidifier section (12) in which air to be conditioned is brought into contact with a first portion of the liquid desiccant; a regenerator section (32) in which outside air is brought into contact with a second portion of the liquid desiccant; and a refrigeration system (45) having a first heat exchanger (46) associated with the first portion of liquid desiccant and a second heat exchanger (36) associated with the second portion of liquid desiccant and a third heat exchanger (136) that does not contact the liquid desiccant.

Abstract: A dehumidifier system comprising: a dehumidifier into which moist air is introduced and contacted with a liquid desiccant solution associated with the dehumidifier to remove moisture therefrom; a regenerator having a liquid desiccant solution associated therewith and contacted with air which removes moisture therefrom, said liquid desiccant solution being in liquid communication with the liquid desiccant solution associated with the dehumidifier; a refrigeration system that comprises a plurality of heat exchangers, a refrigerant and a compressor, wherein the refrigerant passes through the heat exchangers, the heat exchangers including a first heat exchanger in thermal contact with the liquid desiccant solution associated with said dehumidifier, a second heat exchanger in thermal contact with the desiccant solution associated with said regenerator and a third heat exchanger that is not in contact with said desiccant solutions.

Abstract: A dehumidifier system (10) comprising: a dehumidifying chamber (12) into which moist air is introduced and from which less moist air is removed after dehumidification; a desiccant solution (28) situated in at least one reservoir (30); a first conduit (13) via which desiccant solution (28) is transferred from the at least one reservoir (30) to the dehumidifying chamber (12), said solution being returned to said at least one reservoir (30) after absorbing moisture from the moist air; a regenerator (32) which receives desiccant solution from said at least one reservoir and removes moisture from it; a second conduit via which desiccant is transferred from the at least one reservoir (30) to the regenerator (32), said solution being returned to said at least one reservoir after moisture is removed from it; and a heat pump (44) that transfers heat from the solution in the first conduit to the solution in the second conduit.
