Claim:
1. A dehumidification system for use with an aqueous/liquid chiller cooling system used to cool a heating load and including a circulating supply of chilled aqueous/liquid coolant in a recirculating line, said dehumidification system including a desiccant material for removing moisture from a supply/process air stream; a separate direct expansion refrigeration means for cooling the chilled aqueous/liquid coolant in the aqueous/liquid cooling system, said separate direct expansion refrigeration means including at least one condenser for supplying heat through the condenser to a regeneration air stream before the regeneration air stream enters the desiccant material and an evaporator heat exchanger for cooling the aqueous liquid coolant in the aqueous/liquid cooling system; and another, separate heat exchanger directly fluidly connected to said evaporator heat exchanger of the direct expansion refrigeration means, said separate heat exchanger being located in the supply/process air stream, receiving chilled aqueous/liquid from the aqueous/liquid chiller cooling system, and cooling the supply process air stream, the regeneration air stream flowing directly through the condenser to supply heat to the regeneration air stream before the regeneration air stream enters the desiccant material.
