摘　　要：以河南省郑州市某宾馆为例,在地埋管地源热泵系统建设的同时建立了一套能效监测系统,对运行一段时间后系统性能和地温变化进行分析评价。结果表明:制冷工况下系统的能效比为5.74,供暖工况下系统制热性能系数为4.11,能效等级为1级;机组负荷率与系统能效比呈正相关性,循环水泵电耗比与系统能效比呈负相关性;该系统热不平衡率为9.77%,经实测,在经历了一个完整运行周期后,地温基本保持了平衡,地下水渗流和降雨入渗等综合作用带走了一部分热量,降低了其热量的堆积。Taking a hotel in Zhengzhou city,Henan Province as an example,a set of energy efficiency monitoring system was established in the construction of the ground source heat pump system to analyze and evaluate the performance and temperature change of the system after a period of operation.The results show that the energy efficiency ratio of the system under cooling condition is 5.74,the heating performance coefficient is 4.11,the energy efficiency grade is Grade 1;The load rate of the unit is positively correlated with the system energy efficiency ratio,while the power consumption ratio of the circulating water pump is negatively correlated with the system energy efficiency ratio;the thermal imbalance ratio of the system is 9.77%,which keeps balance,groundwater seepage and rainfall infiltration takes away some heat and reduces its heat accumulation.
