Abstract
A ventilation system for a livestock house includes a heat exchanger through which both warm moist air from the interior living area of the house and fresh make-up air from the outside are passed, so that heat will transfer from the former to the latter. Prior to entering the heat exchanger, the warm moist air passes through a filter device that removes particulates from it, so that the particulates do not combine with condensation in the heat exchanger to block the heat exchanger. The fresh air, after being warmed in the heat exchanger passes into an elongated distribution plenum located slightly below the ceiling of the house, and this plenum contains apertures which direct the fresh air horizontally into the living area. Moreover, the upper surface of the plenum is located directly below an elongated opening in the ceiling. Along each side of this opening, baffles are hinged to the ceiling, and these baffles extend obliquely outwardly and downwardly, and contact the upper surface of the plenum at their lower edges. The arrangement is such that the warm moist air from the building is prevented from escaping through the opening and into the attic area above the ceiling, but when e…
