Abstract

A ceiling ventilation inlet (10) includes a housing having an air inlet aperture (14), an air outlet aperture (16), and a baffle (20) supported for linear movement adjacent the air outlet aperture (16). A spring (50) is positioned such that the baffle (20) moves dependant upon air pressure difference between the confinement space and the external environment. Air entering the housing opens the baffle (20) and enters the livestock confinement building in a 360 degree dispersion pattern. The spring (50) causes the baffle (20) to direct the flow of air into the confinement space at a near constant rate so as to optimize ventilation. The greater the air pressure difference between the confinement space and the external environment, the greater the air outlet area becomes. Since the inlet (10) is responsive to the pressure difference and the air outlet area increases or decreases in size, the airflow velocity entering the confinement space may be optimized at a near constant rate. Mathematical equations and limiting parameters define the relationship between the geometrical design of the ceiling ventilation inlet and the optimum and acceptable range of properties for the spring (50).
