ABSTRACT:
A ventilation method and system for automatically repositioning the adjustable closures in a confinement house of the type used for rearing poultry or livestock. A pressure sensor measures the pressure differential between the inside and outside of the house resulting from the operation of one or more exhaust fans, and the adjustable closures are repositioned accordingly by a control device so that the fresh outside air drawn into the house through the ventilation openings enters at an optimum velocity for most effective ventilation of all areas of the house.
