本文以怀来大钢架全玻璃地热温室为例,运用有限差分法,对温室地下供热系统进行了方案比较,并对地下埋管进行了优化设计,诸如埋管结构尺寸、管材的选择以及保温措施等,文章最后指出对地下埋管的防腐以及如何减少地下热损失等都有待进一步研究和探讨,以便在工程上推广应用。
This paper takes Huailai Dagang’s all-glass geothermal greenhouse as an example to compare the underground heating systems of greenhouses with the finite difference method and optimize the design of buried pipes, such as the size of the buried pipe, the choice of pipes, and Insulation measures, etc. Finally, the article points out that the anti-corrosion of underground pipes and how to reduce the underground heat loss need to be further studied and discussed in order to promote the application of the project.
