针对地埋管群敷设过程中需要解决的优化布局问题,引入了管群综合换热能效系数和热堆积系数,利用瞬态三维数值模型对地埋管群传热过程进行了动态模拟,研究了地埋管阵列间距、分块规模和阵列形式对管群综合换热能效系数和热堆积系数的影响。结果显示,加大管间距可增加高效持续换热时间,采用较小的分块规模能有效实现岩土体热平衡,长方形、L形埋管阵列相对于正方形阵列有利于增强换热效果。

Introduces the two conceptions of comprehensive heat efficiency coefficient and heat stack coefficient in order to obtain the optimal arrangement of buried pipe array.Simulates the heat transfer process using the transient three-dimensional heat transfer model of buried pipe array.Studies the influence of pipe group spacing,array size and array type on the comprehensive heat efficiency coefficient and the heat stack coefficient.The results show that increasing pipe spacing can prolong the duration of high-efficiency heat transfer process for buried pipe,smaller array size can effectively achieve heat balance of rock and soil body,and the rectangle or L-typed buried pipe array is more helpful to enhance heat transfer performance compared with the square array.
