摘　　要：半封闭温室是近年来新兴温室,其中温室气候走廊和正压送风系统是半封闭温室的关键系统设计。通过对半封闭温室内夏季温度分布的均匀性和风道风速测试试验,验证温室的降温能力和送风系统性能。试验结果表明,SFG5-4型风机配套35 m长风道,送风相对均匀,风速4.3~4.7 m/s;对于温度分布规律来说,在同一水平方向上温室内各点的平均温差1.0~1.8℃,在同一高度方向上温室内各点的平均温差2.2~3.5℃,并且3.5 m湿帘比2.0 m湿帘降温效果好。Semi closed greenhouse is a new greenhouse in recent years.Greenhouse climate corridor and positive pressure air supply system are the key system design of semi closed greenhouse.Temperature distribution uniformity and wind speed of air duct in semi closed greenhouse in summer were tested to verify greenhouse cooling capacity and performance of air supply system.Test results showed that,domestic fan SFG5-4 was equipped with 35 m long air duct,air supply was relatively uniform,and wind speed was from 4.3 m/s to 4.7 m/s;for temperature distribution rule,in the same horizontal direction,average temperature difference of each point in semi closed greenhouse was within range of 1.0℃ to1.8℃,and in the same height direction,average temperature difference of each point in greenhouse was within range of 2.2℃ to 3.5℃,and 3.5 m wet curtain was better than 2.0 m wet curtain in cooling effect.
