夏季采用湿帘通风系统的密闭式肉种鸡舍温热环境因子的变化

Diversification of Warm Environmental Factors of Closed Henhouse Using Wet Curtain Ventilation System in Summer

选择华南农业大学增城正大肉鸡发展中心的肉种鸡舍为研究对象，在夏季分别对该鸡舍的气温、气湿、风速等温热环境因子进行测定，用以评价该鸡舍采用的湿帘通风系统对鸡舍内温热环境因子的调节效果。结果表明，夏季采用湿帘通风系统的鸡舍平均舍温比舍外气温低3～4℃，相对湿度保持在80％左右；夏季采用湿帘通风系统可以有效地降低舍温，主要表现为前端降温效果明显，后部降温效果有所下降；中间比两侧的降温效果好。表明夏季采用湿帘通风系统对种鸡舍内的温热环境控制较好。

In order to evaluate the effects of regulation for wet curtain ventilation system on the regulation of warm environmental factors in henhouse,we chose the henhouses of Zengcheng Chia Tai broiler development center of South China Agricultural University as the materials,and measured air temperature,humidity,wind speed and other warm environmental factors. The results showed that for the henhouse in wet curtain ventilation system,the average temperature inside henhouse was 3 to 4 degrees lower than that of outside in summer, and relative humidity maintained about 80%. Wet curtain ventilation system could effectively reduce the henhouses＇ internal temperature,which showed that the cooling effect in the front of the house was more significant than the rear of the house,and the middle temperature was low：er than the other two sides. So it could be concluded that wet curtain ventilation system had better control effects on warm environment in the henhouse in summer.
