The ventilation of the house is divided into mechanical ventilation and natural ventilation. When designing the ventilation system, not only the feeding density of the broiler and the local high temperature should be considered, but also the ventilation should be uniform. The standard ventilation amount and the number of feeding should be taken into account for each chicken, and the required ventilation amount should be calculated. The number of fans to be installed in the performance of the Qingzhou fan to be installed is calculated.

When the house length is longer Short-span ventilation is not higher than 10 Apps are more common Negative pressure ventilation system, mold-oriented negative pressure ventilation system design and installation methods are more widely used, mainly used through ventilation. Penetrating ventilation means that the fan is installed on the side wall, and the air inlet is provided at the corresponding part of the opposite wall of the Qingzhou fan. After the fresh air flows in from the air inlet, it passes through the transverse diameter of the chicken house and is discharged outside the house.
