The dehumidifier has a rotary bed 6 containing a thermally regenerable desiccant material, including a process segment 7 and a regeneration segment 8, and an air-to-air heat exchanger A having first and second heat-exchange channels A1 and A2. A process air channel 20 conducts process air through the process segment 7 of the rotary bed, through heat-exchange channel A1 of heat exchanger, to outlet 3. A cooling air channel 22 conducts cooling air from an external cooling air inlet 4a, through heat-exchange channel A2 of heat exchanger A to an exhaust air outlet 5a without passing through the rotary bed. The temperature of the return process air is controllable by a variable speed fan 12. A regeneration air channel 26 conducts air via heater box 9 through the regeneration segment 8 of the rotary bed, to exhaust air outlet 5b.

There is provided a dehumidifying device for dew point temperature adjustment that adjusts a dew point temperature of air to a temperature of about −20° C. or lower, the device including an adjusting unit that adjusts a dew point temperature by adjusting at least one driving operation that is selected from a rotational frequency of a supply fan for supplying air into the dehumidifying device for dew point temperature adjustment, a rotating speed of a dehumidifying rotor, an opening degree of a blow-out air volume adjustment damper, a rotational frequency of an exhaust fan for exhausting air, and an opening degree of an exhaust air volume adjustment damper.

A dry room that controls a dew point temperature in a space to be managed, the room includes a plurality of exhaust units that exhaust air in the space to be managed, in which the plurality of exhaust units are disposed in different regions in the space to be managed, and individually adjust an exhaust amount of the air to be exhausted from each of the regions.

An atmospheric water generator system which includes an air dryer system containing a plurality of air dryers configured to pass ambient air over a desiccant for the desiccant to absorb moisture from the air and a humidifier-dehumidifier system which is configured to humidify a gas mixture using the desiccant and dehumidify the humidified gas mixture to produce freshwater. The atmospheric water generator system includes a closed desiccant loop and a closed gas mixture loop configured such that ambient air does not enter the humidifier-dehumidifier system. The humidifier-dehumidifier system is configured such that the gas mixture passes back and forth between the humidifier and dehumidifier between two and six times in a single pass of the closed gas mixture loop. Also disclosed is a method of generating freshwater using the atmospheric water generator system.
