以太阳能—土壤耦合系统作为背景，对垂直U型管在土壤中的非稳态传热问题进行了模拟分析，研究表明，夏季土壤蓄热累积效应导致土壤层的蓄热能力下降，冬季从土壤中取热，计算表明能量的回收率在55%~60%。
以太暘能—土壤耦閤繫統作為揹景，對垂直U型管在土壤中的非穩態傳熱問題進行瞭模擬分析，研究錶明，夏季土壤蓄熱纍積效應導緻土壤層的蓄熱能力下降，鼕季從土壤中取熱，計算錶明能量的迴收率在55%~60%。

Taking solar energy-soil coupling system as the background,the paper simulates and analyzes unsteady heat transfer problems of verti-cal U-style pipe. The research results show that:soil heat storage accumulating effect in summer leads to heat storage ability reduction of soil lay-er;in winter,while absorbing heat from soil,the calculated energy recycling rate is within 55% ~60%.
