Optimizing Air Inlet Systems for Poultry Housing: Key Considerations for Effective Ventilation

Temperature Management for Poultry Housing:

Temperature Range: The suitable temperature range for the growth and development of chickens is 18-25℃. An effective manufacturing level can be achieved in the middle of 13-28℃. Additionally, the following temperature differentials should be maintained:

• Day and Night: Within 5℃
• Maximum Temperature Difference: Not exceeding 8℃
• Horizontal Temperature: Controlled within 2℃
• Vertical Temperature Difference: Not exceeding 1℃

Ventilation System and Air Inlet:

• Crosswind Effect: – In negative pressure ventilation, crosswind is utilized in both mixed and horizontal ventilation processes to ensure balanced and symmetrical gas distribution while preventing sudden temperature changes.
• Air Inlet Specifications and Models: – Air inlet gaps should ideally run the length of the chicken house to ensure adequate ventilation. Common specifications include width 560mm, height 270mm; width 600mm, height 320mm; or width 700mm, height 300mm.
• Raw Materials: – Air inlets are commonly made of rubber products using injection mold processing with high durability and strong aging resistance. Bird-proof netting on the exterior is recommended.
• Configuration: – The total number and distribution of air inlets should be based on the specific ventilation needs of the chicken house as a whole, rather than solely on its length, to ensure the temperature control system software achieves the expected effect.
• Calculation of Total Number of Air Inlets: – The total number of air inlets should be calculated based on the gas exchange rate, the volume of the chicken coop, and the required air volume for ventilation.
• Installation: – Proper installation of air inlets, located at least 500mm away from the roof and 300mm away from hanging windows, is crucial to prevent oxygen shortage due to inadequate air intake.

By maintaining the appropriate temperature and employing effective ventilation strategies, poultry farmers can create an optimal environment for the health and development of their chickens.
