    • The present invention provides an air conditioning apparatus in which a suction air stream drawn in the rotational direction of a propeller fan as it bypasses a baffle board, and a discharge air stream guided by a guide plate in the anti-rotational direction of the propeller fan toward the inner surface of the baffle board flow in the opposite directions and met each other in the air passage in a suction chamber, so that a powerful vortex of air is generated, the power of which is further increased by the curl plate extending so as to surround the center of the vortex. Therefore, a large quantity of water in the water storage recess in the upper surface of the bottom plate is lifted, and the resultant water turns into water droplets, which are then mixed in large quantities in the suction air stream entering the fan, whereby the water can be evaporated speedily.
