Abstract: An integrated data center resource system includes an absorption cooling subsystem thermally coupled to a hot exhaust stream and configured to produce chilled coolant for cooling data center equipment. A desiccant-based water harvesting subsystem receives at least a portion of the hot exhaust stream to regenerate a moisture-absorbing desiccant, extract water vapor from ambient air, and release and condense liquid water. A carbon capture subsystem downstream of the cooling and water harvesting subsystems removes carbon dioxide from cooled exhaust gas. A control system dynamically allocates the hot exhaust stream among the subsystems to simultaneously provide cooling, recover water, and reduce carbon emissions.
