在热辐射分析理论的基础上 ,推导出一种计算在遮阳网存在时温室内光环境随拱顶覆面材料透射率 τc,遮阳网的透射率 τs及遮光率 φ等因素的变化关系 .在华东型连栋塑料温室中的实测表明 :用该方法计算太阳辐射在温室内的分布情况能取得比较满意的结果
Based on the theory of thermal radiation analysis, a new method to calculate the change of the light environment in the greenhouse with the transmittance τc of the roof cladding material, the transmittance τs of shading net and the shading rate φ in the presence of shading net is derived. Measured in a multi-span plastic greenhouse shows that the method can be used to calculate the distribution of solar radiation in the greenhouse to obtain satisfactory results
