  • Ventilating system for a livestock building
    Patent number: 4249461
    Abstract: A ventilating system for a livestock building includes a substantially enclosed building structure having a ceiling with an attic compartment above it and a livestock compartment below it. An elongated air conduit extends through the building structure substantially parallel to the ceiling and has at least one elongated slot extending substantially the length thereof. A fan or the like circulates air in the livestock compartment through the conduit and outwardly through the slot with a baffle adjacent the slot directing the air exiting therefrom upwardly towards the ceiling. An elongated opening in the ceiling in close proximity and parallel to the conduit is provided for bringing a source of fresh air into the livestock compartment and an air deflector is provided for mixing the fresh air with the circulated air passing through the slot.
