Wall-Mounted Air Inlets for Poultry Farms

Side wall air inlets in poultry farming are a key component of a poultry house’s ventilation system. Their design directly impacts air quality, temperature distribution, and poultry health. The following is a detailed explanation of side wall air inlets in poultry farming:

I. Core Function

Ventilation
Removes harmful gases such as ammonia, carbon dioxide, and dust from the house, introducing fresh air to maintain an oxygen content above 19%.
In closed chicken houses, side wall air inlets work in conjunction with exhaust fans to create negative pressure ventilation, ensuring uniform air flow.
Temperature Regulation
Winter: By controlling the air inlet opening, cool air is directed along the roof for maximum travel, preheating it before falling, avoiding direct airflow onto the poultry and reducing cold stress.
Summer: In conjunction with a wet curtain cooling system, the air inlets introduce cooler air, reducing the house temperature by 5-10°C.
Humidity Control: Maintain a relative humidity of 40%-70% to prevent excessively high humidity, which can lead to the growth of pathogens, or excessively low humidity, which can cause respiratory illnesses.

II. Design Key Points

Adjustable Air Inlets:
Manual Adjustment: Opens and closes manually via slides or hinges, suitable for small and medium-sized farms.
Electric/Pneumatic Adjustment: Linked to an automated control system, automatically adjusts the opening based on indoor environmental parameters (temperature, humidity, and ammonia concentration), suitable for large intensive farms.
Deflector Design: Deflectors installed on the inside of the air inlet diagonally direct cool air along the roof, extending the preheating path and reducing the risk of direct airflow onto the poultry.
