ABSTRACT:
The invention pertains to apparatus for utilizing atmospheric air to cool enclosures, such as refrigerated coolers, computer rooms, and other spaces requiring temperature regulation of cool air. A panel mounted within the enclosure to be cooled includes an atmospheric air grill inlet communicating through an air duct with an air supply fan located within atmospheric air for forcing cool atmospheric air through the grill. The panel also includes an interior exhaust fan within the enclosure communicating with an air duct for exhausting enclosure air to atmosphere, and temperature sensing control means for both fans sense the temperature within the enclosure and that of the atmospheric air to simultaneously actuate the air supply and exhaust fans which are of substantially equal air flow capacity wherein the air pressure within the enclosure remains substantially constant while supplying cool atmospheric air thereto.
