1.养猪工业化
2.猪场通风模式类型
100% Pit Ventilation=Downflow of ventilating air完全的粪坑通风=换气风向下
Grouping of Fans in Ventilation Houses通风室里不同类别的风机
Single Fan Controller for multiple rooms可控多个房间的单独风扇控制器
Unique Duct system=uniform distribution of fresh air单独的通风管道系统=新鲜空气分布平均Integrated Heat Exchangers整合的热交换室
All Air Flows through the attic所有的空气流动都会经过阁楼
Multiple Room Capability—Common Pit多个房间——同一个粪坑
Age segregation by room--AIAO pigflow 每个房间对应着不同年龄的猪群——全进全出
Air work典型的热交换室
Ventilation operating and Control is a 3 step process 换气操作有三个步骤：
Main Controller —constantly senses average room temperatures through the common pit and controls fan operation主控制器 ——通过粪坑感应器持续的感应猪舍平均温度和控制风扇运作
Manual hallway slides —set for minimum needs of each pig room manually. Normally adjust once a week. 手动走廊滑板——设定每个房间的最小通风量。通常每周调节一次
Automated Room Controller —senses individual room temperatures and adjusts each rooms ceiling inlets to provide more or less incoming fresh air to the room.自动房间控制器——感应每个房间的温度，然后通过调节屋顶的空气进口大小来提供适量的空气进入房间
Heat Exchangers recover heat exhausted from the pit fans that would otherwise be wasted. This dramatically decreases heating costs and improves air quality within the building.热交换室收集了废气当中原本会被浪费的热量。这大大降低能耗的同时，还改善了猪舍里空气的质量。
All the minimum air that enters the pig space is tempered in the hallway
所有进入猪舍里的最小需求量的空气都会在走廊里被进行适当的调节
弥散顶棚的好处ADVANTAGES OF PERFALU
< 铝制，更卫生，易于清洁，持久耐用Aluminium made for better hygiene, easy cleaning and durability.

< 多孔多向，气流安全而匀称Multi holes—Multi direction for safe and homogenous air diffusion.
<低风速但因多孔而风量高/可与篮式风机结合使用
Slow air speed and high debit of new air due to multi holes / can be combined with basket fans
< 室内环境更舒适=猪只舒适，生长更快更安全
Better ambiance into the room = animal comfort, fast and safe growth.
< 加热和降温的最佳风量=节能 Air volume optimization for Heating/Cooling = energy saving.
< 可用于中央通风或烟囱式通风Can be used for centralized ventilation or chimney.
< 可用于正压或负压猪舍Can be used for positive or negative pressure building.
猪舍环境控制的目的
交换新鲜空气，排出猪只及粪便所产生的有害气体（氨气、二氧化碳、硫化氢）
根据猪只体格或年龄大小，控制每个房间的环境/室内温度
控制进入舍内的湿度（基于室外湿度）
保持水泥漏缝地板干燥，保证猪只舒适度
控制所需供热量
使用水帘或喷雾系统清新空气
去除室内猪只或饲料产生的灰尘
猪的生物学特性
每比临界温度低一度 ，则一头成长猪每天损失的活重为10-12g . 1?C的差距造成每头猪生长期必须额外花费?1.00的饲料成本。
For every degree the LCT(lower critical temperature)a growing pig looses apptoximately10-12g of liveweight gain per day. A level of 1 ℃below the LCT during the growing period could cost￡1.00 in extra feed per pig 3-35
实例: 400 头育肥猪的房舍
冬季 通风量 = 16,9m3/h
共计冬季气流= 16,9 x 400 = 6.760m3/h
春秋季通风量 = 59,2m3/h
共计夏季气流= 59,2 x 400 = 23.680m3/h
夏季通风量= 202,8m3/h
夏季总计气流 = 202,8 x 400 = 81.120m3/h

猪场环境控制的创新
1.猪舍内气体的排放处理。
2.节能环保的通风设备。
3.物联网时代食品的可追溯。
猪场环境控制的创新
Special wood chips arranged in a filter remove 95% of the dust and 60 to 85% of the odor from exhaust fans.在过滤器里安装的特殊的木片有效去除了废气扇排出的95%的灰尘和60%-80%的臭气
