对地热井位于不同层位、出水温度45～95℃、出水量70～150 t/h，带调峰锅炉的地热与热泵供热系统进行了全面分析。结果表明，最优系统设计回水温度与室内地板供暖设计回水温度之差约为1℃；最优地热一级换热器一次侧出水温度与最优系统设计回水温度之差为1．6～1．7℃；最优调峰负荷占总负荷的比例为37％～40％；不区分地热井出水温度、出水量，一味强调最低的地热尾水温度及最大的地热利用率是不经济的。

Performs a comprehensive analysis of the geothermal and heat pump heating system with peak-shaving boiler with geothermal well located in different positions, where geothermal water temperature is between 45 ℃ and 95 ℃ and geothermal water discharging rate is between 70 t/h and 150 t/h.The results show that the temperature difference between the optimal system design backwater and indoor floor heating design backwater is about 1 ℃.The temperature difference between the optimal discharging water of primary side of the first heat exchanger and the optimal system design backwater is from 1.6 ℃ to 1.7 ℃.The optimal peak-shaving load takes 37% to 40% of the total load.It is not economic to only emphasize the lowest geothermal backwater temperature and the maximum geothermal utilization rate,without consideration of geothermal water temperature and geothermal water discharging rate.
