北京密闭式商品蛋鸡舍冬季环境研究(初报)

Winter Environment Analysising on Enclosed Commercial Layer Housing in Beijing

对北京地区的典型密闭式蛋鸡舍的冬季环境进行了测试分析。结果表明：对三七外墙和２００ｍｍ厚加气混凝土屋面的密闭式蛋鸡舍，每只蛋鸡的通风量为１．３ｍ３／ｈ时，可维持舍内外温差１９℃左右，舍内ＣＯ２浓度２１００×１０－６左右，最高ＮＨ３浓度不超过１８×１０－６。不同的进气口形式与位置对舍内温度、有害气体的分布影响较大。

In order to find the environment distribution in enclosed layer housing in winter, some research work was done in Beijing region. Temperature diference between inside and outside could be about 19℃, the CO 2 consistence was about 2 100×10 -6 , the NH 3 consistence was no more than 18×10 -6 when the ventilation rate is 1 3 m 3/h for each layer. The forms and locations of air inlets affect obviously the distribution of inside temperature and harmful air components.
