The environment of the broiler house was studied by Airpak software. Optimal design of the air inlet device for the typical broiler house in the cold region, including its guide length and direction of guide flow. The optimized air inlet device helps to improve the air flow in the broiler house, and then changes the environmental factors such as the distribution of temperature, the distribution of wind speed and the distribution of carbon dioxide in the house. The length of the best diversion device should be about 1m and not more than 2m. The influence of the flow direction of the air inlet device is affected by the length of the guide flow. The increase of the direction of the air inlet device leads to the rise of the body plane temperature and the overall wind speed, and the distribution of carbon dioxide is basically unchanged. The best direction of diversion should be 30°～45°. Keywords
