In the ventilation management of the house, the complexity of house air flow and wind speed should be considered. By rationally configuring the wet curtain and air inlet, the temperature difference of various positions in the chicken house can be improved. To keep the body temperature of the chickens stable, reduce the stress of the chickens, promote the normal growth and egg production of the chickens, and finally achieve a stable and high-yielding environment.

Management of ventilation equipment
Precautions for summer ventilation in chicken coops
It is necessary to regularly inspect and maintain the ventilation equipment of the chicken house to ensure the best performance of the ventilation equipment. For example, clean the shutters and fan blades, and check the tension and aging of the fan belt at any time. Check whether the speed of the fan impeller reaches the standard. The slower speed of the fan will cause the ventilation speed of the chicken house to slow down, and the cooling effect of the fan cannot be exerted. Also, pay attention to the commissioning and maintenance of the generator. Overhaul and install each part of the wet curtain in advance according to the weather conditions, especially the water outlet of the pipeline above the wet curtain. Ensure that the water flow is evenly distributed, and rinse the wet curtain clean before use.
Generally, the negative pressure ventilation in summer can well ventilate and cool the inside of the chicken house. When the temperature outside the chicken house reaches above 35°C, it is difficult to cool down by the negative pressure ventilation alone.
At this time, a humidifying curtain can be added to assist in cooling. The cooling principle of the wet pad is that when the outdoor hot air is drawn through the damp pad paper by the fan, the water on the damp pad paper can evaporate and take away a lot of heat when it encounters the hot air so that the hot air passing through the damp pad becomes cold air. When ventilating the chicken house, there are several points to pay attention to: first, ensure that the chicken house is well sealed; second, avoid the wet curtain being exposed to the sun and reduce the service life; thirdly, in summer, the airflow rate in the closed chicken house is usually kept at 0.25 to 2.5 m/s, and the open house should reach 1.0 to 1.5 m/s.
