Waste Heat Air Conditioner

Abstract

A system for use as an air conditioning and heating system that uses waste heat to dehydrate a desiccant. The desiccant is then used to dry air. A water sprayed onto an extended, fanned surface is used to harness evaporative cooling of air in contact with the evaporator surface. According to one aspect of the invention, plant spray irrigation surfaces are used as a means to expose water in a dried air environment to cool the air by contact and to produce cool air. The combination of cooled and dried air produces a comfortable environment, i.e., air conditioning.

1 . A cooling system for providing warm, dry air, comprising:
 a. providing hot water to a heat exchanger;   b. flowing a desiccant through the heat exchanger to heat the desiccant to remove water from the desiccant;   c. transferring the dried desiccant to a storage tank;   d. communicating internal air from a room to be conditioned;   e. passing the internal air over a ceramic bed into an external chamber;   f. cooling air in the external chamber using a flow of external ambient air;   g. moving the internal air to an internal chamber;   h. cooling the internal air with a second flow of external ambient air;   i. removing a concentrated desiccant from the storage tank and spraying the desiccant onto internal air in the internal chamber to dry the internal air;   j. communicating the dried, cooled internal air to the room to be conditioned.
