在对现有太阳池进行计算研究的基础上,针对目前北方太阳池冬季要经历结冰期这一现状,提出了表层结冰后太阳池辐射透射模型及热传导模型,将结冰情况考虑到太阳池的运行中,所提出的太阳池模拟计算中考虑了太阳池表面结冰对其整体性能的影响,为太阳池的长期连续性运行提供了研究基础。根据实际温度资料及气象条件,对结冰情况中太阳池的运行进行了数值模拟,得到:在不考虑结冰过程中冰内掺杂尘土等杂质或表面有积雪覆盖时,冬季考虑表面有冰层的太阳池储热性能优于不考虑表面冰层覆盖的情况,另外表层结冰很大程度上减少了太阳池盐梯度的维护。
Based on the calculation of the existing solar pool and the current situation of the northern solar pond going through the icing season in winter, the radiation transmittance model and the heat conduction model of the solar pool after surface icing are put forward. Taking the icing into consideration, In the operation of the pond, the proposed simulation of the solar pond has taken into account the influence of the icing on the surface of the solar pond on its overall performance and provided the research foundation for the long-term continuous operation of the solar pond. According to the actual temperature data and meteorological conditions, the operation of the solar pool in icing condition was numerically simulated. It is found that when the ice is not considered, The thermal storage performance of the solar pool in the ice layer is better than that without considering the surface ice coverage. In addition, the surface icing greatly reduces the maintenance of the solar pool salt gradient.
