摘　　要：阐述了猪舍蒸发降温系统的理论和应用研究现状;比较分析了各种蒸发降温系统的优缺点。湿帘风机降温系统较适合应用于低湿地区的密闭式猪舍;高压喷雾降温系统较适合应用于低湿地区的开放式和密闭式猪舍。高湿地区夏季可考虑给猪洗澡或间歇性喷水的方式对猪体进行降温。除湿降温系统是特别针对高湿地区设计的,但目前还处于研究阶段。蒸发降温系统降温能力有限,可结合遮阳网、保温屋顶等其它的降温方式使用。随着理论研究和应用研究的发展,智能环境控制系统是猪舍环境控制的发展方向。This paper introduced the research situation of evaporative cooling system in piggery.The advantages and disadvantages of each evaporative cooling system were analyzed.The conclusion showed that pad-fans system was more effective for the cooling of closed piggery in low humidity area,and high pressure spray system was more effective for the cooling of open piggery and semi-enclosed piggery in high humidity area.Bathing or intermittent spraying was considerable for the cooling of pigs in high humidity area.The dehumidifying cooling system would be considered for the cooling of piggery in high humidity area,but there are still several problems to be solved.For the limit of cooling ability about evaporative cooling system,other settings should be combined,for example,solar-shading screen,heat preservation roof,etc. With the development of the theoretic and applied study,intelligent environment control system should be the current.
