Abstract: A method and apparatus for destratifying heat within an enclosure wherein a fan is positioned near the ceiling to draw warm air off the ceiling propelling same along a distribution tube also located near the ceiling and wherein the tube is provided with a plurality of openings along the bottom thereof through which the warm air is discharged toward the floor of the enclosure in the form of high velocity jets which entrain large quantities of surrounding ceiling air moving same to the vicinity of the floor of the enclosure.

Abstract: The present invention is for a housing structure for enclosing a fan assembly comprising a drive motor and propeller fan coupled thereto, the housing structure being mounted externally of a building at a downwardly slanted angle thereto so that as airflow is effected through the building when the fan is operating the air exits the building in a downward direction. The entrance to the housing is normally provided with a plurality of moveable blades in a louvered shutter assembly which when in open position have a downward angle thereto corresponding to the downwardly slanted center line axis of the housing enclosure. A fan inlet guard is normally provided with release clips to permit the quick and easy removal of the guard for servicing of the fan structure. The housing also is provided with sufficient area adjacent to the intake opening for permitting installation of electrical wiring to the internal components.

Abstract: A support assembly for a cooling pad evaporation system to be used in an opening within the wall of a building and having a water conductor provided with spaced openings in the top thereof, a cover for the water conductor which dissipates water completely over the top surface of the pad, a plurality of individually distinct cooling cells, and a gutter positioned below the pads. The cover is made up of two major structural pieces; one being the rear piece which is attached to the wall, and the other being a front piece with one end extending over and interlocking with a flange located on the top of the rear piece. Inside the cover is a top cover connector, which is an inverted "L"-shaped member providing a uniform surface for deflecting the upwardly directed water down onto the pads, water conductor support brackets and a water conductor.
