地源热泵是一项节能环保的新型空调技术。为了促进地源热泵在变电站中的推广应用，分析了变电站地源热泵系统的技术经济条件、建筑负荷条件以及变电站地源热泵机组的配置。给出了变电站中地源热泵系统初投资上限、系统能效比下限、投资回收期上限、建筑物负荷下限及机组配置方式。

Ground-source heat pump is a new air-conditioning technology with energy saving and environmental protection. Some issues on the applicability of ground-source heat pump were investigated, such as the techno-economic condition, building load condition and capacity configuration, for its popularization and application in substations. This study puts forward some suggestions on the applicability of ground-source heat pump in terms of the upper limit of initial investment, the lower limit of energy efficiency ratio (EER), the upper limit of investment recovery period, the lower limit of building load and the collocation mode of heat pump unit.
