Abstract

PURPOSE: To improve the exhaust efficiency of the hen yard while preventing accumulation of dust in the ceiling of the hen yard by proper selection of the hood layout or aspects.
CONSTITUTION: When an exhaust fan 8 is put into action, outside air is sucked into a hen yard 1 as shown by the arrow separately through air inlets 2a and 2b on both sides of the yard and ascends together at the center of the yard. Then, it is exhausted length-wise with respect to the ceiling from the first exhaust port of a ceiling 1c via a hood and then outside from the second exhaust port. At this point, as each hood 6 is staggered alternately lengthwise, the exhaust discharged from the hood 6 disturbs the stream, hitting against the adjacent hoods. In this manner, the exhaust efficiency can be improved simply by changing the layout or aspects of the hood 6 while accumulation of dust in the ceiling can be prevented positively.
