The ventilation of the chicken house in winter is very important. Poor ventilation not only affects the healthy growth of the flock. And it affects the humidity of the chicken house. The requirement of air exchange in the chicken house is to meet the minimum demand for chicken activities. Today, the poultry farming equipment manufacturer tells you the importance of ventilation.
Because the chickens with higher stocking density have higher requirements for the small environment of the chicken house. Therefore, it is necessary to increase the air exchange rate as much as possible. To ensure that the air in the chicken house is fresh. The ventilation of the chicken house should pay more attention to the quality requirements. Good ventilation will not bring drastic changes to the temperature in the chicken house. It will also take away the dirty air in the chicken coop.
The damper and fan are used correctly. Fresh air enters through the damper, mixes with the hot air at the top of the house, and then drops to the lower end of the house, filling the entire house. The excess air is exhausted by the fan.
The effective area of the air inlet is the smallest area where a certain amount of air enters the chicken house. The amount of air entering the chicken house through the air inlet is constant, and the smallest cross-sectional area through which this amount of air passes is the effective area of the damper. The effective area of the damper should be perpendicular to the direction of the wind speed. When the damper is opened parallel to the roof, the bottom corner of the damper at this time makes the wind entering the chicken house only one direction, and the wind direction parallel to the roof should be the maximum opening angle of the damper under ideal conditions.
The reflected air is on the cross section of the chicken house, and a cool breeze can be felt at the same height as the air door. The specific location can be estimated by calculation. When the wind speed of the air inlet is constant, the smaller the opening of the air door, the greater the change in the direction of the air volume; the closer to the side wall, the worse the air mixing effect.
In order to ensure the overall effect of ventilation, there must be proper spacing between the dampers. Or there must be a certain number of dampers and a certain amount of exhaust air. The wind speed of the air inlet depends entirely on the number of dampers. It is necessary to ensure that the air inlet has a suitable wind speed, but also to ensure the overall ventilation effect of the chicken house, which is related to the number of air doors. Too few air doors will affect the overall ventilation effect. There will be dead spots in the chicken coop. If there are too many dampers, it is difficult to guarantee the wind speed of the air inlet, and it is difficult to open the dampers.
