Abstract
A method of ventilating an animal enclosure such as a poultry house which permits alternating use of powered sidewall ventilation, natural sidewall ventilating and powered tunnel ventilation dependant upon outside temperature, with automatic control of the ventilation devices to insure safe and effective use. At and below a predetermined low outside ambient temperature, sidewall ventilation exhaust fans are operated to exhaust air drawn into the animal enclosure through the sidewall ventilation openings while tunnel ventilation openings are closed and tunnel ventilation fans are disabled to achieve a relatively low level of powered air movement through the animal enclosure. Between a predetermined middle range of outside ambient temperature, the sidewall ventilation openings are opened while disabling both sidewall ventilation exhaust fans and tunnel ventilation exhaust fans to achieve natural cross-ventilation through the animal enclosure. At and above a predetermined high range of outside ambient temperature, the sidewall ventilation openings are closed, the sidewall ventilation exhaust fans are disabled, the tunnel ventilation openings are opened and the tunnel ventilation exhaust fans are operated to achieve a relatively high level of powered air movement through the animal enclosure.
