| 摘 要： | 针对日光温室土地利用率低,单体小不能进行立体栽培果树种植,不利于机械化操作等问题。该文提出一种大跨度主动蓄能型温室,该温室南北走向,双屋面拱形钢骨架结构,并采用主动蓄放热系统进行能量的蓄积与释放。该试验以传统砖墙日光温室作为对照,对大跨度主动蓄能型温室室内外温湿度以及主动蓄放热系统的能量收支进行分析,并对比2种温室的建造成本,综合分析了试验温室保温节能效果及经济效益。结果表明:大跨度主动蓄能型温室土地利用率高达87.4%。温室夜间平均气温高于10℃,无极端低温,晴天夜间平均气温比对照温室高1.5~3.1℃,比室外高13.9~19.3℃;阴天夜间平均气温比对照温室高1.2~2.8℃,比室外高12.5~18.9℃。夜间室内相对湿度平均比对照温室低7%~10%。主动蓄放热系统性能系数COP(coefficient of performance)为3.4~4.2,平均每天能耗0.013 k Wh/m2,与传统燃煤锅炉加温系统相比,平均节能率为47%。大跨度主动蓄能型温室建造成本每平米307.2元,比传统砖墙日光温室低144.5元。大跨度主动蓄能型温室是一种土地利用率高,单体大,保温性能良好,能进行冬季果菜生产的新型温室类型,且投入少,综合其经济环境效益,值得推广应用。
