Cow shed ventilation can be divided into natural ventilation and mechanical ventilation. For hot and humid areas, natural ventilation alone is obviously not enough. Therefore, it is necessary to choose the cowshed fan. The fan can drive the ventilation volume of the shed, which can reduce the stuffiness and temperature in the shed. However, both natural ventilation and mechanical ventilation are inseparable from the control of details. Today we will discuss the ventilation of the cowshed in a few details.
The ventilating capacity of the cowshed depends on the ventilating capacity of the cowshed fan. As a common plant and breeding greenhouse equipment, the fan is popular because it can exchange the air inside and outside the shed and has good ventilation effect. In the greenhouse, the uniformity of the air distribution depends on the location, design and adjustment of the air intakes. By designing the layout of the air inlet and adjusting the size of the air inlet, the wind speed of the air inlet can be increased (244-305m/M in) without depending on the change of ventilation volume (without changing the number of fans running). The inlet size can be adjusted manually or automatically.
Only by setting the air inlet reasonably, sealing the internal doors and Windows and air leakage, the cowshed fan can form the required negative pressure. The fresh air outside the shed enters the shed through the air leakage opening, which reduces the air volume entering the shed through the designed air inlet and disturbs the air distribution. Therefore, the cowshed should pay attention to air leakage.
