In the longitudinal ventilation of the house, the exhaust fans are all concentrated on the gables or the two sides of the wall near the gable (pollution side) at one end of the house, and the air intakes are installed on the gables at the opposite end of the house or on both sides of the vicinity. On the wall (net road end), the flow of the interior wind tends to be oriented, that is, the airflow is evenly discharged from one end of the house to the other end along the longitudinal axis of the house. Longitudinal ventilation in the house can save electricity and improve the microclimate in the house. It can also prevent mutual interference between chicken houses and reduce noise in the house, which is also conducive to health and epidemic prevention. Longitudinally ventilated chicken houses also eliminated the low egg-laying rate of laying hens in winter and windwards in the horizontal ventilation, and less egg production and higher mortality in laying hens in summer. To implement vertical ventilation in the house, attention must be paid to the following: 1. Exhaust fans must be centrally arranged in the contaminated area of ​​the house, and the distance between the fans should be no less than 0.5 m to prevent insufficient suction area of ​​the suction fan on the suction side. And caused "grab the wind." Second, exhaust air compressors must use large and medium-sized axial fans for agriculture and animal husbandry. The inlet area must be larger than the exhaust area, typically 2:1. In order to ensure ventilation, all doors and windows except the air inlet are sealed. Before using the fan, open the air inlet and start it again. Stop the fan when feeding to prevent pumping.
