ABSTRACT:
A ventilation inlet includes a housing having two air inlets apertures, a solid wind-deflecting rear wall, and a baffle supported for pivotal movement about a pivot point. A spring or other biasing mechanism is operatively connected to the baffle. Air entering the housing opens the baffle and enters the livestock confinement building. The baffle, positioned responsive to the amount and pressure of air entering the housing, directs the flow of air into the confinement space so as to optimize the speed and direction of the external fresh air entering the confinement space. The design of the ventilation inlet is optimized by calculating the necessary operators required to enable the baffle to properly respond to the incoming air.
