| 摘 要： | 采光优化设计是节能日光温室结构优化设计的关键和改进温室环境性能最经济有效的方式。本试验以寿光市10m跨度的下挖式节能日光温室为例，对我国北方地区下挖式节能日光温室合理采光时段屋面角进行了理论计算与分析，并利用计算线阴影的原理，通过计算不同时刻下挖壁面在室内形成的阴影区域，提出了我国北方地区下挖式节能日光温室适宜的下挖深度，为目前下挖式节能日光温室的设计建造提供理论依据和技术参数。

| Abstract: | Optimization design of lighting is very important for optimization design of energy-saving sunlight greenhouse structure,and it is the most cost-effective means to improve greenhouse environmental performance.In this paper,the sunken-type energy-saving sunlight greenhouse with 10-m span in Shouguang City was taken for example.The front roof angle within reasonable lighting time of sunken-type energy-saving sunlight greenhouse in northern China was calculated and analyzed in theory.Using the principle of calculating line shadow,the feasible sink depth of sunken energy-saving sunlight greenhouse in north China were put forward through calculating the indoor shaded regions of the greenhouse formed by the front sunken wall at different times of the day.It could provide theoretical basis and technical parameters for the current design and construction of sunken energy-saving sunlight greenhouse. |
