摘　　要：本文基于建立的垂直埋管换热器管群土壤源热泵系统模型,分别分析了土壤源热泵系统应用于办公、商场、住宅、宾馆这四种不同功能建筑时土壤热物性参数、回填料导热系数、埋管规模参数、埋管内流体流量、土壤初始温度及系统日运行时间等因素对系统整体长期(10年)运行性能的影响情况。并且用一元线性或非线性模型回归得到了系统运行10年的平均COP及土壤10年的温升与主要影响参数的关系式,使各参数的影响程度得到量化,以期对土壤源热泵系统的实际工程应用提供参考。Based on the established ground-source heat pump system with multiple boreholes vertical single U-tube ground heat exchanger, this paper analyses the influences on the long-term （10 years） operating performance of the system of such factors as thermal parameters of soil, thermal conductivity of grout, scale parameters of boreholes and buried pipes, flow rate in pipe, original ground temperature and operation modes, when the ground-source heat pump is used in office buildings, shopping malls, residential buildings and hotels, respectively. Both the linear and non-linear single regression techniques are used to obtain the regression equations of the average COP and the soil temperature rise change of the system operating 10 years with the main parameters, to quantitative analysis the separate effects of these factors, in order to provide guidance for the actual ground-source heat pump system projects.
