摘　　要：介绍了土壤源热泵“热堆积”问题的机理,将解决“热堆积”问题的策略总结为三种。第一种是根据实际工况采取适当的控制策略,包括基于温度的控制策略、运行时间控制策略。第二种是从地源侧系统的角度优化孔井参数、提高回填材料热物性。第三种是构建复合地源热泵系统,增加辅助散热系统。同时分析比较了不同策略的优劣势、使用条件,为工程上土壤源热泵系统的设计提供参考。After introducing the mechanism of“heat accumulation”problem of ground-coupled heat pump,this paper summarizes three strategies to solve“heat accumulation”problem.The first is to adopt appropriate control strategies according to operating conditions,including temperature-based control strategy and running time control strategy.The second is to optimize borehole parameters and improve the thermal properties of backfill materials from the perspective of ground source side system.The third is to build a compound ground-coupled heat pump system and add an auxiliary heat dissipation system.This paper analyzes and compares the advantages and disadvantages of different strategies,and provides reference for the design of ground-coupled heat pump system in engineering.
