Patent ID: 8827779

Claim:
An apparatus for cooling ventilation air for a building, comprising: a radiating panel assembly comprising a plurality of radiating panels, said radiating panel assembly having an emissive surface for use on said building such that said emissive surface of said radiating panel assembly is directed skyward at night, such that said radiating panel assembly is cooled due to radiation heat loss from said radiating panel assembly to a cool night sky, and ambient air proximal to said radiating panel assembly is cooled by transferring heat to said radiating panel assembly which radiates said heat via said radiation heat loss to said cool night sky, and said radiating panel assembly defines an air collection space between itself and a skyward facing portion of said building, said radiating panel assembly having a plurality of air openings for ambient air cooled by said radiating panel to pass through the plurality of air openings to the air collection space; a passageway between said air collection space and an interior of said building and located for passage of cooled ambient air from said air collection space into said interior of said building; and a fan located for moving said cooled ambient air from said air collection space to a lower portion of said air collection space and through said passageway to said interior of said building.
