蒸发冷却已在很多鸡舍和温室中成为典型措施,在美国西南部地区也常用于猪舍及奶牛舍中。在美国北部地区,为寒冷气候条件下所设计的温室及密闭畜舍,当夏季偶而出现暴热天气时,几乎无法进行控制。如无缓解措施,炎热的夏季将造成明显的死亡损失。然而大部分的损失呈较隐蔽的形式出现,如降低生产能力和繁殖效率。这种由热应激所造成的损失可以采用适当的蒸发冷却系统而得到降低。 Evaporative cooling has become a classic practice in many sheds and greenhouses and is also commonly used in pigsty and dairy cows in the southwestern United States. In the northern part of the United States, greenhouse designs and enclosed barns designed for cold climates are virtually unmanageable in the event of occasional violent summer weather. Without relief, a hot summertime will result in significant loss of life. However, most of the losses are in a hidden form, such as reduced productivity and reproductive efficiency. This loss of heat stress can be reduced by using a suitable evaporative cooling system.
