The ventilation of the house is mechanically ventilated and natural Two kinds of 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. Qingzhou Fan to be installed to calculate the performance of the fan The number of units.

      Natural ventilation uses windows, which are carried out under natural wind and temperature differences. The total window area (in North China) is generally about 1/3 of the building area. For uniform ventilation in the house, the windows should be symmetric and evenly distributed. In order to adjust the ventilation, the window can also be made into two rows, and some windows can be switched according to the ventilation requirement, which can utilize both natural wind and temperature difference ventilation. In the winter, in order to prevent the cold wind from blowing directly to the chicken, a windshield can also be installed to evenly enter the house after the wind speed is reduced. The ideal window structure is divided into three layers, the inner layer is barbed wire, which is good for preventing wild birds from entering and preventing beasts. The middle is the glass window frame, and the outer layer is plastic film, which is mainly used for winter insulation.

      Qingzhou Fan Mechanical Ventilation is the main method for regulating the environmental conditions in closed houses and broilers under high density and large group feeding conditions, ventilation and temperature control, humidity control, dust removal and Adjusting the air composition is closely related. The mechanical ventilation methods of contemporary broiler closed chicken houses mainly include two types, namely horizontal ventilation and longitudinal ventilation. These two ventilation methods have advantages and disadvantages. In the design of the chicken house, the appropriate method can be selected according to the actual situation.

      When the length of the house is less than 10 meters, horizontal ventilation is often used. The horizontal ventilation mainly has two designs of positive pressure system and negative pressure system. The so-called positive pressure ventilation system relies on the Qingzhou fan to suck the outside fresh air into the house, so that the air in the house is discharged by the exhaust port due to the increase of air pressure. Although the system can adjust the temperature inside the house, the system can improve the house temperature. The distribution of internal air, reducing the thief wind in the house, but because of its high equipment cost, high cost, difficult installation, narrow application range, etc., it is less used in production practice.

      The most common application is the negative pressure ventilation system. The mold-oriented negative pressure ventilation system has many design and installation methods. The most widely used is the through-type 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.
