Abstract:
An air conditioning system for conditioning a process stream of air wherein the air is dehumidified and cooled to provide a conditioned stream of air for introducing to a conditioned space, the system comprised of:(a) an adsorption wheel having a multiplicity of passages through which process air can flow for adsorbing moisture therefrom, the wheel capable of adsorption of moisture from said process air and of regeneration on a continuous basis as the wheel rotates;(b) an indirect evaporative cooler in fluid communication with said adsorption wheel, the indirect evaporative cooler having a dry side and a wet side separated by a wall wherein heat is extracted from said dry side through the wall to said wet side, cooling in said dry side achieved by evaporation of water into air passing through said wet side;(c) means for passing the process air through said adsorption wheel to remove moisture therefrom to provide a moisture-depleted stream of process air exiting said adsorption wheel;(d) means for regenerating said adsorption wheel by passing hot gases therethrough to remove moisture from said adsorption wheel;(e) means for dividing said moisture-depleted stream of process air exiting said adsorption wheel into a primary stream and a secondary stream, the secondary stream comprised of drier air than said primary stream; and(f) means for introducing said secondary stream of process air into said wet of said indirect evaporative cooler and for introducing said primary stream into said dry side, secondary stream evaporating water thereinto thereby cooling said wall and removing heat from said primary steam to provide cooled air to be introduced to a conditioned space.
