摘要
应用有限单元法对土壤源热泵地下垂直埋管周围土壤的非稳态温度场进行了数值模拟 ,其结果与实验测试值吻合较好 ,根据数值模拟计算程序可给出垂直埋管向地下放热量与埋深、埋管的热作用半径的对应关系 ,作垂直埋管埋深、数量及间距的设计参考依据。
The finite element method was adopted in the numerical simulation for the ground temperature field of the U-shaped vertical loop of pipe.The results were in accordance with measured data perfectly.The relationship of the heat release,the buried depth of the pipe and the heat influencing radius of the pipe was given,which could be a reference of the practical design.
