Ventilation appts. for poultry house - has fan-driven ventilators with trunking that oscillates vertically and horizontally to provide even distribution of air to entire floor space

摘要

Moving the roof section up and down (arrow 6) allows air to escape (7). Rows of ventilators (8, 9), connected by bellows (10) to openings (11, 12) in the walls (3), allow ingress of fresh air (13). The ventilators (8, 9) tilt in the vertical plane with an oscillating motion (arrow 16) to direct the airflow (14, 15). The ventilators (8, 9) also tilt horizontally with an oscillating motion. Ventilators have deflector vanes and their fan speed is adjustable. An even distribution is assured with no 'dead ground'. Automatic control compensates for inside and outside air temperature. The humidity can also be adjusted.
