ABSTRACT:
An improved, high efficiency, combination fill assembly for crossflow cooling towers is provided which employs a strategically located, multiple sheet film fill section in conjunction with splash-type fill to maximize tower performance with a minimum tower height, pumping head requirements, and pressure drop across the assembly. In preferred forms, the fill includes a film fill section presenting substantially separate air and water entrance and exit faces, along with structure above the upper water entrance face thereof for dispersing water and inhibiting exiting of cooling air out of the water entrance face; in this fashion "short circuiting" of cooling air is inhibited, and the inertia of airflow is thereby maintained in the desirable crossflowing direction for enhanced water cooling. Separate film packs cooperatively define the overall film fill section, and the packs are advantageously arranged in an inwardly staggered relationship, with the uppermost pack being outermost, i.e., closest to the air entrance face of the fill assembly. Splash fill is employed in the regions of the overall assembly free of film fill packs.
