Energy pile structure based on shaping phase change material backfilling and operation method thereof
The invention provides an energy pile structure based on shaping phase change material backfilling and an operation method of the energy pile structure. The energy pile structure sequentially comprises a pile core heat injection base material A, a heat removal heat shield base material B and a concrete shell from inside to outside. A heat injection pipe is arranged in the pile core heat injection base material A, and a heat removal pipe is arranged in the heat removal heat shield base material B; the heat extraction heat shield base material B is internally connected with the pile core heat injection base material A, and is externally connected with the concrete shell; the pile core heat injection base material A and the heat extraction heat shield base material B are both made of shaped phase change materials; and the heat removal heat shield base material B adopts asymptotic phase change, so that the problems that underground cold and heat loads are unbalanced, a ground temperature field is unbalanced, inter-pile heat interference is serious, underground heat transfer efficiency is low, and the heat and cold supply capacity and energy efficiency of a system are not expected and are reduced year by year when an existing shallow soil source heat pump energy pile supplies heat and cold are solved.
本发明提供一种基于定型相变材料回填的能源桩结构及其运行方法，由内向外依次包括桩芯注热基材A、取热热屏基材B以及混凝土外壳；桩芯注热基材A中设置有注热管，取热热屏基材B中设置有取热管；取热热屏基材B内接桩芯注热基材A，取热热屏基材B外接混凝土外壳；桩芯注热基材A、取热热屏基材B均为采用定型相变材料；取热热屏基材B采用渐近相变，从而解决现有浅层土壤源热泵能源桩供热供冷时存在的地下冷热负荷不平衡、地温场失衡、桩间热干扰严重、地下传热效率低、系统供热供冷能力及能效不及预期且逐年降低等问题。
