A method of exchanging heat comprising the steps of providing a heat exchange apparatus having a direct evaporative section and an indirect evaporative section, the direct evaporative section comprising a plurality of fill sheets, the indirect evaporative section comprising a plurality of circuits each conducting a fluid stream, spraying an evaporative liquid generally downwardly through the direct evaporative section, moving air generally upwardly through the direct evaporative section, collecting the evaporative liquid that passes through the direct evaporative section in a re-spray tray, spraying the collected evaporative liquid through a plurality of re-spray nozzles downwardly onto the indirect evaporative section, and moving air generally downwardly across the indirect evaporative section. view more

The method of claim 16 wherein the spray of collected evaporative liquid from the re-spray nozzles is generally uniform across the indirect evaporative section.
