Claim:
An air conditioner comprising: a plurality of plates arranged in a successively stacked configuration with portions thereof having a spaced apart arrangement, and defining between successive adjacent pairs of plates at said spaced apart portions a first and second series of discrete alternating passages and liquid collecting means for collecting a liquid in the first series of passages, said liquid collecting means comprising a reservoir defined within each of the first series of passages proximate the second end of the plurality of plates for collecting the flowing liquid; and at least one liquid drain conduit extending through the plurality of plates in fluid communication with the reservoir for receiving the liquid from the reservoir, wherein a first air stream is passed through the first series of passages and a second air stream is passed through the second series of passages; and said stacked configuration of plates forming integrally therewith a liquid delivery means for delivering from a source a sufficient quantity of a liquid to the inside surfaces of the first series of fluid passages in a manner which provides a continuous flow of the liquid from a first end to a second end of the plurality of plates while in contact with the first air stream.
