The detail control problem of cowshed fan in cowshed

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; Cowshed ventilation can be divided into natural ventilation and mechanical ventilation. For hot and humid areas, natural ventilation alone is obviously not enough. Therefore, you need to choose a cowshed fan. The fan can drive the ventilation in the shed, which can reduce the sultry heat in the shed and reduce the temperature. However, both natural and mechanical ventilation are inseparable from the control of details. Today we will discuss the ventilation of the bullpen from a few details.

The ventilation of the cowshed depends on the ventilation of the cowshed fan. As a common planting and breeding greenhouse equipment, the fan is welcomed because it can exchange the air inside and outside the shed, and the ventilation is good. In the greenhouse, the uniformity of the air distribution depends on the location, design and adjustment of the air inlet. Without relying on changes in ventilation volume (without changing the number of operating fans), by designing the layout of the air inlet and adjusting the size of the air inlet, the air speed of the air inlet (244-305m / M in) can be increased. The size of the air inlet can be adjusted manually or automatically.

Only by properly setting the air inlet, sealing the inner doors, windows and air leakage, can the cow house fan form the required negative pressure. Fresh air outside the shed enters the shed through the air leak, reducing the amount of air entering the shed through the designed air inlet and disturbing the airflow organization. Therefore, the cowshed should pay attention to air leakage.

Where are the air leaks, let's take a look at what is included:

Open doors, windows and hay troughs. Air enters too much from one place, making the other place poorly ventilated. Cracks around walls, roofs, doors and windows. Even small openings can interfere with good air distribution. Connect to two barns or a spout or scraper port between two barns. Use removable doors or heavy curtains to block these large openings.
