In chicken farms, ventilation management of chicken houses is crucial. Tunnel ventilation is an effective ventilation method, especially suitable for large-scale laying hen farms. Let us analyze the necessity of tunnel ventilation in chicken farms.
1.The role of ventilation:
Provide fresh oxygen: Chicken metabolism requires breathing oxygen and expelling carbon dioxide. Ventilation provides a source of oxygen to the chickens.
Discharge dirty waste gas: ventilation takes away ammonia, carbon dioxide, hydrogen sulfide and other waste gases in the chicken house.
Control dust: Good ventilation can help reduce the accumulation of dust in the chicken house.
Reduce indoor humidity: Proper ventilation can regulate humidity and maintain a comfortable environment.
Regulate the temperature inside the house and make the temperature uniform in all parts of the house: Ventilation helps to discharge the exhaust gas from the house at the right time and at the same time make the temperature uniform in all parts of the house.
2.Ventilation method:
Tunnel ventilation: Tunnel ventilation is a longitudinal ventilation method that installs a water curtain at one end of the chicken house and arranges a fan at the other end for negative pressure exhaust. This system is suitable for maximum ventilation of the chicken house in summer.
Mixed ventilation: In addition to longitudinal ventilation, a certain number of air inlets are installed on the side walls of the chicken house, and 1-2 exhaust fans are installed in the middle for minimum ventilation in winter. According to the needs of the season, horizontal and vertical ventilation can be converted, and the size of the air door switch and ventilation mode can even be automatically controlled by the computer.
3.”Minimal” cross ventilation management in winter:
The focus of chicken coops in winter is insulation, but ventilation cannot be ignored. To balance insulation and ventilation, a cross-ventilation pattern with “minimized” ventilation is required.
The principle of using the minimum ventilation volume is to install a “minimize” ventilation time controller on the basis of the temperature controller control. This ensures uniform air quality and temperature in the chicken house.
In short, tunnel ventilation is indeed necessary in chicken farms. It can improve the air quality, temperature and humidity in the chicken house and improve the production performance of the chickens.

In chicken farms, the location of vents and air inlets is crucial. Here are some suggestions for setting up your vents and intakes.
4.Location of air inlet:
Good outdoor air quality: The air inlet should be located in a place with good outdoor air quality.
Upwind side of the air outlet: The air inlet should be lower than the air outlet and located on the upwind side of the air outlet. If the elevations of the air inlet and exhaust outlets are similar, different directions should be selected.
Avoid facing aerodynamic shadow areas and positive pressure areas: The air outlet should not face outdoor aerodynamic shadow areas or positive pressure areas.
Louver margin setting: The louver margins of the air inlet and exhaust vents should be set in accordance with relevant standards.
5.Height of air inlet:
The distance between the bottom of the air inlet and the outdoor floor should not be less than 2 meters. If the air inlet is located in a green belt, the bottom should not be less than 1 meter from the ground.
6.Location of the air outlet:
The exhaust outlet should be far away from the elderly, children’s activity areas, adjacent openable exterior windows, and key personnel entrances and exits.
If the exhaust outlet is close to the outdoor activity area, the bottom of the exhaust outlet of the underground garage should not be less than 2.5 meters from the outdoor floor, and the bottom of other outlets that remove waste heat and moisture should not be less than 2.0 meters from the ground.
7.Determination of wind speed:
The determination of the air outlet wind speed should be comprehensively considered based on the functional properties of the building, noise evaluation standards, and the maximum air volume in normal operation.
In short, the vents and air inlets should be set in appropriate locations according to specific circumstances to ensure that the air quality, temperature and humidity in the chicken house are effectively controlled and to improve the production performance of the chickens.
