Abstract: A dual-function desiccant cycle system (10) simultaneously dehumidifies air for a conditioned space (110), such as a data-centre server hall or HVAC supply plenum, and harvests atmospheric fresh water as a second useful output. A rotary desiccant wheel (101) is partitioned into an adsorption sector (101 A) and a regeneration sector (101B). Atmospheric air (100) passes through the adsorption sector (101 A) to yield a dehumidified supply airstream (102) directed to an airhandling unit (111) of the conditioned space (110). A waste heat recovery circuit, comprising a waste heat recovery heat exchanger (130) and a regeneration airstream pre-heater coil (140), extracts waste heat from a chiller condenser loop (121) of a chiller plant (120) serving the said conditioned space (110), and uses the said waste heat as substantially the sole energy input to preheat a regeneration airstream. The regeneration airstream passes through the regeneration sector (10IB) to desorb moisture, yielding a moisture-laden regeneration exhaust airstream (103). A water generation module (150), comprising passive or active condensation means or a hybrid thereof, condenses water vapour from the regeneration exhaust airstream (103). A controller (180) cooptimises cooling-load reduction and fresh-water yield. The system accordingly provides closed- loop atmospheric moisture management with dual useful outputs and near-zero additional primary energy input for desiccant regeneration.
