摘　　要：在垂直地下换热器的埋管长度计算中,存在着很多导致误差的参数。本文利用一种误差分析方法,通过一个实例计算过程,分析在地源热泵的埋管长度计算中各个误差参数对计算结果的定量影响,最后列出各个误差参数的重要级别,为工程设计提供一定参考。There are many influencing factors in the length determination of vertical ground heat exchangers, which would result in some calculation errors. Presents a methodology to calculate these errors, provides an example calculation, which analyzes the specific impacts of all parameters on the length determination, and determines the influencing grades of all parameters, provides some reference for projects design.
