| 摘 要： | 在热泵制热工况下,超强吸水树脂与源土混合作为回填材料,分别对螺旋盘管、U型管以及整个系统进行了实验研究,得出系统性能变化曲线。实验结果表明,超强吸水树脂与源土混合作为回填材料,特别是螺旋盘管换热器,可明显增大地下换热器换热量,提高地源热泵系统的效率和稳定性,适用于干旱、土壤非饱和以及地下水位比较低的地区。

| Abstract: | A super absorbent polymer has high water absorbency and good thermal conductivity,which was mixed with the original soil as backfilled material of the ground source heat pump.In heat model,spiral coil ground heat exchanger(GHE)and U-shaped GHE were tested,respectively.The results were analyzed in detail and prepared into some curves.The result showed that the super absorbent polymer mixed with the original soil as backfilled material,obviously the extracted heat of the under-ground heat exchanger is increased,and the COP is improved and is stable of the system,it is suitable for the droughty,unsaturated soil area or where the underground water lever is low. |
