FORCED VENTILATION STRUCTURE OF BARNS

摘要

A forcible ventilation structure of a stall is provided to keep temperature constant and proper condition in the stall by smoothly circulating the air to the lower side of the stall by exhausting the fresh air flowing into an intake duct after passing through domestic animals by opening a third curtain from the lower side of a window toward the upper side thereof. The forcible ventilation structure of a stall is composed of a wall body(10) having windows(12) installed on both sides; a roof(20) covering the upper side of the wall body; a first curtain(30) installed at the outside of the wall body and opened upward from the lower side of the window; a second curtain(40) installed in the wall body and opened downward from the upper side of the window; an intake duct(60) mounted on the roof to suck in the external air; a third curtain(50) installed in the second curtain and opened upward from the lower side of the window by an opening and closing unit to guide the air mixed with the external air sucked by the intake duct, to the lower side of the stall; and an exhaust duct(70) mounted between the second and third curtains and equipped with a blower fan(74) forcibly exhausting the mixed air guided by the third curtain.
