The climate in the house depends on the combination of ventilation, heating and cooling. The choice of ventilation system must also be adapted to external conditions. Regardless of whether the ventilation system is simple or complex, it must first be able to be manipulated by humans. Even if it is a fully automatic ventilation system, the perception of the eyes, ears, nose, and skin of managers is also an important reference.
Natural ventilation does not use fans to promote air flow. Fresh air enters the chicken house through blooming air inlets, such as adjustable air inlet valves and roller shutters. Natural ventilation is a simple and low-cost way of ventilation.
Even in areas with good natural ventilation, farmers are increasingly choosing mechanical ventilation. Although hardware investment and operating costs are high, mechanical ventilation can better control the environment in the chicken house and bring better breeding results. By means of negative pressure ventilation, the air is pulled into the chicken house from the air inlet, and then forced out of the chicken house. The effect of mechanical ventilation depends on the control of the air inlet. If there are blooming holes on the side wall of the chicken house, it will affect the operation effect of the ventilation system.
Horizontal ventilation: The fan draws fresh air from one side of the chicken house, and exhausts it from the other side after crossing the chicken house. The ventilation system can be set to a small and large amount of ventilation.
Side window ventilation: The air inlet is set on both sides of the chicken house, and the fan is installed at one end of the chicken house. This kind of ventilation method is suitable for areas with little temperature changes throughout the year (such as marine climate areas), and its equipment investment and operating costs are relatively low.
