A method of conditioning a process stream of air in an air conditioning system wherein a process stream of air is dehumidified and cooled to provide a conditioned stream of air for introducing to a conditioned space. The method comprises the steps of providing 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 the process air and of regeneration on a continuous basis as the wheel rotates. An indirect evaporative cooler is provided having a dry side and a wet side separated by a moisture-impervious wall wherein heat is extracted from said dry side through the wall to the wet side. Cooling in the dry side is achieved by evaporation of water into air passing through the wet side. The process air is passed through the adsorption wheel to remove moisture therefrom to provide a moisture-depleted stream of process air exiting the adsorption wheel. The adsorption wheel is regenerated by passing hot gases therethrough to remove moisture from the adsorption wheel. The moisture-depleted stream of process air exiting said adsorption wheel is divided into a relatively hot stream and a relatively cool stream, and the relatively hot stream of process air is introduced into the wet side of the indirect evaporative cooler, and the relatively cool stream is introduced into the dry side, the relatively hot stream evaporating water thereinto thereby cooling the moisture-impervious wall and removing heat from the relatively cool stream to provide cooled air to be introduced to a conditioned space.

[ What is claimed is:] [1.] A method of conditioning a process stream of air in an air conditioning system wherein a process stream of air is dehumidified and cooled to provide a conditioned stream of air for introducing to a conditioned space, the method comprising the steps of:(a) providing 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) providing an 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) 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) regenerating said adsorption wheel by passing hot gases therethrough to remove moisture from said adsorption wheel;(e) 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 and hotter air than said primary stream;(f) introducing said secondary stream of process air to a heat exchanger thereby cooling said secondary stream to provide a stream of cooled secondary air; and(g) introducing said stream of cooled secondary air into said wet side of said indirect evaporative cooler and introducing said primary stream into said dry side, said stream of cooled secondary air evaporating water thereinto thereby cooling said wall and removing heat from said primary stream to provide cooled air to be introduced to a conditioned space.
