屋面形状对日光温室光环境的影响模拟

Influence Simulation of Greenhouse Light Environment from Roof Shape

借助中国农业大学研发的日光温室光环境模拟预测软件,模拟研究了不同屋面形状类型对日光温室内光环境的影响。结果表明:双圆、椭圆和直线圆弧组合这3种不同的屋面形状,对日光温室内光环境的影响非常小,椭圆屋面光辐射累计量相对大一些,但也只有0.048%的差别。因此,从光环境角度看,在温室建造时,无需过多考虑屋面形状的影响。

Influence of roof shape type on light environment in greenhouse was simulated and studied by greenhouse light environment simulation software of China Agricultural University. Results showed that effect of light environment was very small from3 different roof shape,such as double circular arc,elliptical and linear combination. Optical radiation accumulation of elliptical roof was relatively large,but difference only was 0. 048%. Therefore,without too much considering influence of roof shape when a greenhouse was built from perspective of light environment.
