Description

  The present invention relates to a structure for effectively ventilating a poultry house.

In a closed house rather than an open type, a plan view is constructed so that outside air is taken in from the outside air intake provided on one end of the house and exhausted from an exhaust fan installed on the other end of the house. In the ventilation structure of a rectangular poultry house, the temperature difference between the part close to the outside air intake and the part close to the exhaust port becomes large even inside the same poultry house, and fresh outside air cannot be obtained in the part near the exhaust port. There was a problem.
Therefore, an auxiliary outside air intake extending between the substantially central part of both side walls in the longitudinal direction of the poultry house and the portion corresponding to the end close to the exhaust outlet of the cage row is provided, and the inlet air adjustment at the outlet of the auxiliary outside air intake is provided. A structure of a poultry house configured to adjust the opening and closing and the opening degree of the plate by a signal from a temperature sensor provided in the poultry house before and after the auxiliary outside air intake is proposed. (For example, see Patent Document 1)
