[ What is claimed is:] [1.] In a method of cooling a first stream of air in an air conditioning system wherein a first stream of air is dehumidified and cooled in first and second indirect evaporative coolers for purposes of conditioning a second stream of air for introducing to a conditioned space, the method comprising the steps of:(a) providing an adsorption wheel having an adsorbent contained in a paper web and having a multiplicity of passages through which said first stream of air can flow for adsorbing moisture therefrom, the wheel capable of adsorption of moisture from said first stream of air and of regeneration;(b) passing said first stream of air through said adsorption wheel to remove moisture therefrom;(c) regenerating said adsorption wheel by passing hot gases therethrough to remove moisture from said adsorption wheel;(d) providing a first indirect evaporative cooler and second indirect evaporative cooler, said first and second indirect evaporative coolers having dry channels and wet channels separated by moisture-impervious walls wherein heat is extracted from said dry channels to said wet channels through said walls;(e) introducing air after passing through the adsorption wheel to said dry channels of said first indirect evaporative cooler to provide a cooled stream of air exiting said dry channels of said first indirect evaporative cooler;(f) directing a portion of said cooled stream of air to said wet channels of said first indirect evaporative cooler;(g) directing a second portion of said cooled stream of air exiting said dry channels of said first indirect evaporative cooler to the wet channels of said second indirect evaporative cooler for purposes of cooling said dry channels of said second indirect evaporative cooler;(h) circulating a second stream of air to the dry channels of said second indirect evaporative cooler for providing conditioned air for introducing to the conditioned space; and(i) adjusting the humidity of said second stream of air prior to circulating said second stream of air to the dry channels.
