ABSTRACT:
An air to air heat exchanger particularly for contaminated air from an animal barn or the like includes a core formed by a plurality of thin-walled flexible plastics tubes supported at respective ends in tube sheets. The tubes are held under tension and arranged vertically in parallel rows and columns so that cold fresh air enters parallel to the rows horizontally beneath the upper tube sheet and then moved downwardly along the outside of the tubes to escape horizontally parallel to the rows above the lower tube sheet. The contaminated warm air passes from a plenum beneath the lower tube sheet upwardly along the inside of the tubes to an outlet at the top of the tubes. This direction of movement of the air causes a self-cleaning effect by condensate at the top of the tubes running down and cleaning the interior of the tubes of any collected contaminants. The design also enables the use of convenient inexpensive flexible tubes without allowing air movement to cause unacceptable flexing.
