摘　　要：对地源热泵系统运行情况进行测试是了解热泵系统运行与能耗的重要手段。通过对某地源热泵工程冷热工况运行数据的统计分析,讨论了冷热工况下耗电量、地源侧供回水温差、室内外温度差和能效比之间的相互关系,得出:在用户侧供回水温差基本一致的情况下,地源侧供回水温差越大,机组运行的能效比越高,相应的耗电量就越小。Testing the operation of ground source heat pump system is an important means of understanding its operation and energy consumption.Through statistical analysis of the operating data of a ground source heat pump project under cold and hot working conditions,this paper discusses the relationship between power consumption under cold and hot working conditions,supply and return water temperature difference of ground source side,indoor and outdoor temperature difference,and energy efficiency ratio.It is concluded that,under the condition that the supply and return water temperature difference of user side is basically the same,the larger temperature difference of ground source side,the higher the energy efficiency ratio of the unit operation,and the corresponding power consumption is smaller.
