An air handler especially for use with a produce storage room has a housing with an air inlet near the bottom and an air outlet near the top. A fan or blower supplies air above atmospheric pressure to the inlet for flow through the housing and discharge from the top thereof and through a duct leading to the storage room. Adjacent the housing there is a water cooler, usually operated in a refrigerator circuit, into which water is introduced from a collector near the bottom of the housing and from which the cooled water is discharged into a distributor in the housing near the top thereof. The distributor, preferably a number of sprays, discharges the cooled water to fall over and through a water and air baffle unit within the housing between the inlet and the outlet thereof and into the collector. The water and air baffle unit has a plurality of expanded metal plates, conveniently of aluminum, extending substantially horizontally across the interior of the housing between the distributor and the collector, with the metal plates vertically separated and supported to provide intervening, cross spaces for air and water flow.

An air handler especially for use with a produce storage room comprising a housing having an upright tubular portion, a transversely enlarged lower portion immediately below said tubular portion, a reduced vertical inlet portion opening into the bottom of said enlarged lower portion, an enlarged vertical outlet portion opening from the top of said tubular portion, means for supplying air above atmospheric pressure to said inlet portion, means for conducting air from said outlet portion to said storage room, a water cooler, a water collector positioned substantially centrally in said enlarged lower portion spaced above and extending entirely across said inlet portion and spaced below and extending entirely across said tubular portion, said collector being of less transverse dimension than said enlarged portion to provide an air flow path therearound from said inlet portion to said tubular portion, a water distributor in said outlet portion, means for withdrawing water from said collector and propelling said water through said water cooler to said distributor to fall from said distributor through said tubular portion back to said collector, a transverse grid base extending across said enlarged lower portion above said collector, and a water and air baffle unit in said tubular portion in the path of water falling from said distributor to said collector, said unit including a plurality of superposed expanded metal flat plates having diamond-shaped openings between connecting bars therein and each extending horizontally substantially across said housing, said unit also including vertical rods at their lower ends resting loosely on said transverse grid base for transverse movement and supporting individual ones of said plates at vertical intervals from adjacent ones of said plates to provide intervening spaces between said plates for air and water flow.
