Abstract:
1. Apparatus, comprising: a wetting chamber; an air intake opening leading to an air flow pathway through the wetting chamber; an air outtake opening leading from the air flow pathway through the wetting chamber; an atomizer; a liquid reservoir; a liquid delivery system for moving liquid from the liquid reservoir to the atomizer; the atomizer for receiving the liquid from the liquid delivery system and dispersing the liquid into the air flow pathway in a form of atomized liquid; the liquid reservoir disposed for collecting the atomized liquid from the wetting chamber; a first heat exchanger disposed at the intake opening; a second heat exchanger disposed at the outtake opening; and a liquid circulation system for circulating liquid between the first and second heat exchangers; wherein the atomizer comprises: an impeller, mounted for rotation, disposed in the wetting chamber and arranged to receive liquid from the liquid delivery system; and means for imparting rotation to the impeller; whereby rotation of the impeller produces the atomized liquid from the liquid received by the impeller from the liquid delivery system, and disperses the atomized liquid into the air flow pathway.
