The Thermal-Based Liquid Desiccant Air Conditioner consists of four modules: Air Movement, Dehumidification, Temperature Adjustment and Regeneration Modules. The first 3 modules may be combined while the Regeneration module may be placed separately with connection by small plastic pipes and electrical service. Systems are available in 3000, 4500 and 6000 Series that provide 1,800, 2,750 and 4,000 cfm respectively.

Outdoor air driven by the Air Movement Module enters the air supply side of the Dehumidification Module. There, through the process of multi-stage differential dehumidification, its moisture content decreases without temperature increase. This dry air flows into the Temperature Adjustment Module where it is cooled by indirect evaporative cooling and optionally by direct evaporative cooling (saturation) and is then distributed to the building. Saturator moisture addition is controlled by an indoor humidistat thereby maintaining a comfortable indoor relative humidity even in harsh climates.

After gaining heat and moisture in the building, the air enters the return side of the Temperature Adjustment Module where it is cooled to its saturation temperature in the indirect evaporative coolers and then flows to the return side of the Dehumidification Module. There it remains saturated and increases in temperature while absorbing heat from the supply air by means of liquid-to-liquid heat exchangers. Finally, the exhaust air is discharged into the atmosphere. The desiccant solution becomes diluted after absorbing moisture from the air in the Dehumidification Module. It is recirculated to the Regenerator Module to be reconcentrated and returned to the Dehumidification Module for reuse.

For certain fresh air or dehumidification applications, the modules may be specified separately rather than as a complete system. For example, the Dehumidification and Regenerator modules may be used together when GENIUS is specified as part of a larger system. Alternatively, for a stand alone dehumidification system, the Air Movement module may be added.
