摘　　要：目前在实际工程中计算地埋管管长主要是使用简便的单位延米换热量法,但是实际工程运行结果表明这种计算方法虽然简便但计算出的管长数偏小,在运行一段时间后地源热泵的运行效果将会下降。通过对南京6个实际工程项目的地埋管管长计算分析,分别就间歇运行和连续运行两种地源热泵系统运行模式,提出了满足不同节能目标要求下的单位延米换热量法计算管长的修正方法。At present the main underground pipe length is calculated using a simple unit heat transfer method in practical engineering. But the operation results of actual project show that this calculation method is simple but the length of pipe calculated too small. After running for a period of time, the ground source heat pump operating re- sults will fall. By analyzing and calculating the pipe length of six actual projects in Nanjing. According to different operation modes of ground source heat pump system, respectively advance the requests of satisfying different energy- saving targets under unit meter heat transfer method to calculate the correction method of length.
