 Monitors the operating conditions of a ground-source heat pump project in Beijing, and analyses the changes of soil temperature, supply and return water temperature in air conditioning side and ground side, power consumption and heat transfer capacity per meter. The test results show that the soil temperature varies seasonally with the running time, fluctuating within (15±10) ℃, and the system runs steadily. The average heat transfer capacity per meter in winter and summer is about 40 W/m and 66 W/m, respectively. The heating consumption in winter is about 41.2% of the total consumption in the whole year. The project can save an average standard coal of 327.18 t per year, and the energy saving effect and economic benefits of ground-source heat pump system in cold zones are remarkable.
