研究以数值分析为手段,以能源桩系统为对象,将融雪过程以微分方程的形式输入至数值模型,分析桩内回路对能源桩取热的影响,比较增设储热水箱与直接利用浅层地热能对系统融雪效果的不同。结果表明:能源桩内部回路为螺旋型布置时,能够提供较多的浅层地热能。利用能源桩系统为道面提供热量进行融雪,随持续时间的增加,可融雪面积减小。当增设储热水箱时,系统运行过程分为雪前储热和雪中融雪两个阶段。保证水箱在雪前储热阶段达到稳定温度,有效增加可融雪面积,并随储能水箱体积的增加,达到稳定温度所需时间增加,可融雪面积边际效用递减。在实际使用过程中,增加储能水箱可明显提升能源桩系统的融雪水平,水箱体积的确定需要根据融雪能耗和机场管理情况综合确定。
In this study, by means of numerical analyses, taking the energy pile system as the object, the snow melting process is input into the numerical model in the form of differential equations, and the influence of the loop inside the pile on heat extraction is analyzed; the difference in snow melting effect between adding heat storage water tank and direct shallow geothermal energy methods is compared. The study shows that when the internal loop of the pile is spiral, it can provide more shallow geothermal energy. The energy pile system is used to provide heat for the pavement to melt snow, and the area of melting snow decreases with the increase of duration. When the heat storage tank is added, the operation process of the system can be divided into two stages: pre-snow heat storage and snow melting. Ensuring that the water tank reaches a stable temperature in the pre-snow heat storage stage can effectively increase the snow-melting area. Additionally, with the increase of the water tank volume, the time needed to reach the stable temperature increases, and the snow-melting area shows the diminishing marginal utility. In the process of practical use, increasing the energy storage tank can significantly improve the snow melting ability of the energy pile, and the determination of the water tank volume needs to be taken into consideration comprehensively according to the snow melting energy consumption and airport management.
