本文介绍了在我国各地不同类型鸡舍内纵向通风系统的应用情况;分析了湿垫蒸发降温对我国各地气候的适应性。实际应用结果表明:纵向通风结合湿垫降温系统可将我国各地的不同类型鸡舍的夏季气温基本控制在28～30℃以下,舍内气流速度可达1.0～2.0m/s,气流分布均匀,可为鸡群提供100％的新鲜空气;一般,夏季蛋鸡和种鸡的产蛋率可提高5％以上,饲养密度可提高10％～20％,制止了高温应激死鸡;且较传统的横向通风节约电能和运行费用达40％以上。
This paper introduces the application of longitudinal ventilation system in different types of pens in different parts of China. It also analyzes the adaptability of wet mat evaporative cooling to the climate throughout China. The practical application results show that the longitudinal ventilation combined with the wet pad cooling system can basically control the summer temperatures of different types of chicken coops around 28 ~ 30 ℃, the airflow velocity in the house up to 1.0 ~ 2.0m / s, the airflow distribution is uniform, Can provide 100% fresh air for the flocks; in general, laying hens and laying hens in summer can be increased by more than 5%, raising the density can be increased by 10% ~ 20%, to stop the high temperature stress-induced dead chickens; and more traditional The lateral ventilation saves energy and operating costs up to 40%.
