摘　　要：基于某地源热泵系统节能运行的需求,本文分析了系统原有运行策略的弊端,提出了新的基于室内初始温度的运行策略,并通过供水温度调节实验验证其节能性;且根据系统运行现状进行旁通阀关闭实验。结果表明:在外界天气状况及变化趋势相近的条件下,冷冻水供水温度从11℃提高至12℃,系统2 h累计节省耗电量37.8 kW·h;关闭旁通阀后循环水泵在35 Hz下运行3 h,累计节省耗电量7 kW·h。Based on the energy saving demand in operation of a ground water heat pump system （GWHP）,this study analyzes the disad？vantages of the original operation strategy and proposes a new operation strategy based on indoor initial temperature. It is validated by awater supply temperature regulation experiment that the new operation strategy can save energy compared to the original operation strategy.The bypass valve closing test is carried out according to the operation status of the system. Both of these tests are carried out in late June.The results show that in similar external weather conditions and trends,the chilled water supply temperature changes from 11 ℃ to 12 ℃,and the cumulative power of the system in two hours is reduced by 37. 8 kW·h. The cumulative power is reduced by 7 kW·h when circulating water pump runs at 35 Hz for three hours after the bypass valve is closed.
