楼房猪场可节约占地面积,楼房猪舍常增设新风过滤装置和排风除臭墙用以改善舍内环境和减少废气排放。为了解此类楼房猪舍夏季环境控制情况,选择北京郊区某楼房猪舍的三个楼层作为监测对象,底层(1层)、中间层(3层)和顶层(5层)新风过滤装...楼房猪场可节约占地面积,楼房猪舍常增设新风过滤装置和排风除臭墙用以改善舍内环境和减少废气排放。为了解此类楼房猪舍夏季环境控制情况,选择北京郊区某楼房猪舍的三个楼层作为监测对象,底层(1层)、中间层(3层)和顶层(5层)新风过滤装置洁净度分别为优、差和良,中间层和顶层风机开启6台,底层风机开启5台,通过监测猪舍的温度、湿度和二氧化碳浓度(质量分数)、风机处静压差等环境参数,分析楼房猪舍不同楼层通风量、温度、温度分布均匀度及环境舒适度。结果显示,底层、中间层和顶层风机处静压差分别为69.7、110.1和98.7 Pa;高静压差导致猪舍实际通风量和风机能效比降低,猪舍实际通风量中间层(205313 m^(3)/h)和顶层(233611 m^(3)/h)显著低于底层(247903 m^(3)/h)(P<0.05),风机能效比中间层(15.3 m^(3)/(h·W))和顶层(17.4 m^(3)/(h·W))显著低于底层(22.5 m^(3)/(h·W))(P<0.05);底层舍内温度(24.2℃)显著低于中间层(24.6℃)和顶层(24.7℃)(P<0.05),舍内不同位置同期最大温差(0.4℃)显著低于中间层(1.1℃)和顶层(0.6℃)(P<0.05),综合温湿度和风速计算母猪等效温度指数(Equivalent Temperature Index for Sows,ETIS),底层最小,中间层最大。该研究可为楼房猪舍提高通风效率、优化楼房猪舍夏季环境控制方案提供理论依据。展开更多
