Study on optimization effect of south roof curve of Chinese solar greenhouse

To maximize the use of solar energy and increase the utilization area of Chinese solar greenhouse (CSG) land, a solar greenhouse radiation model was established based on previous studies, combining with the law of solar movement, meteorological data, and optical properties of materials. The model is verified by selecting the measured data of typical sunny days. The results show that the optimization of the south roof curve of the greenhouse can not only increase the land-use area in the greenhouse but also increase the solar energy captured by the solar greenhouse. And the CSG in the greenhouse, the land-use area in the greenhouse increased to 42 m2, the lighting rate of the south roof, and the lighting rate of the ground increased 15.2% and 0.78% respectively. The amount of interception in the back wall of the greenhouse was reduced by 0.67%, and that in the greenhouse was increased by 2.22%. The optimal structure CSG in Shenyang (span 9 m) is the optimal shoulder height position, obta..., , , To maximize the use of solar energy and increase the utilization area of Chinese solar greenhouse (CSG) land, a solar greenhouse radiation model was established based on previous studies, combining with the law of solar movement, meteorological data, and optical properties of materials.
