摘要
地下岩土原始温度和运行中温度场变化是决定地能利用系统设计及能否长期稳定运行的关键因素.本文通过监测严寒地区大型地源热泵工程运行重要参数,特别是利用地下换热系统设置地下岩土温度监测孔,通过监测系统采暖期、制冷期和间歇期1年运行过程中,地下孔群纵向和径向岩土温度对负荷的响应及地温恢复情况,讨论热泵机组地温变化能效影响规律,为严寒地区地能利用系统实际工程运行及设计提供有效参考.
The initial soil temperature and the change of underground temperature field in operation are the key factors for system design and long term stable operation for using geothermal energy system. By monitoring important operation parameters of a large ground source heat pump （GSHP） project in severe cold region, especially the temperature measuring devices have been set in monitor holes to measure the horizontal and vertical variation and the restoration of soil temperature field for the response of load in heating period, cooling period and intermittent period of the year. By the rule of the influence of the coefficient of performance （COP） of the heat pump for the variation of soil temperature, it provides valid reference for project operation and design for using geothermal energy system in severe cold area.
