| 摘 要： | 针对传统湿帘风机系统存在温湿度不均匀,无法调控冷空气温度;对温室密闭性要求较高,不适用于节能型日光温室等问题,借鉴国外半封闭温室降温方式,对日光温室正压式湿帘风机降温系统结构参数优化与应用效果进行研究。结果表明:最优的湿帘风机系统结构参数为,湿帘厚度150 mm,单位面积水流速4 L/(min·m~2),直径50 cm、均匀打孔、孔距20 cm、孔径1 cm、反光膜材料的通风筒;与对照温室相对,此系统最高可降温10℃,室内温度基本全天均低于室外,在距地面1.5 m水平面上各处的温差在2℃以内,湿度差在7%以内,垂直方向上距地面3 m以下的温差在3℃以内。此降温系统能够有效的降低夏季日光温室的温度,且温室各处的温湿度比较均匀,可以为我国节能型日光温室提供有效的夏季降温措施。
