Patent ID: 6938434

Claim:
Apparatus comprising: a wetting chamber; an intake duct for conducting intake air to the wetting chamber; an outtake duct for conducting outtake air from the wetting chamber; the intake and outtake ducts constructed and arranged to isolate intake air flow through the intake duct from outtake air flow through the outtake duct; a thermally conductive component for transferring heat between the intake duct and the outtake duct; a liquid reservoir; a liquid transfer system for moving liquid from the reservoir to the wetting chamber and for dispersing the liquid into the wetting chamber and into a flow of air passing therethrough from the intake duct to the outtake duct; the reservoir disposed for collecting the liquid from the wetting chamber; a thermally conductive portion of the liquid transfer system intermediate the reservoir and the wetting chamber for transferring heat between outside the thermally conductive portion and the liquid passing therethrough from the reservoir to the wetting chamber; a conditioning air duct having an inlet and an outlet; and the thermally conductive portion disposed in the conditioning air duct between the inlet and the outlet.
