Abstract
An air conditioning system includes an evaporator assembly and a condenser assembly. A first portion of the exhaust airstream leaves the condenser and enters a primary channel of an evaporative coolerassembly. Water evaporates from the evaporative cooler tubes and creates a moisture-laden airstream. A plurality of apertures in the evaporative cooler tubes bleeds the moisture-laden airstream intoa secondary channel defined within the evaporative cooler tubes. The heat drawn from the air in the primary channel produces an evaporatively cooled airstream that enters a desiccant wheel. A solid desiccant material within the desiccant wheel absorbs moisture from the evaporatively cooled airstream to produce a dehumidified airstream that enters the evaporator assembly. A second portion of the exhaust airstream is directed through a heater and then into the desiccant wheel to provide heat for regeneration of the solid desiccant material.
