摘　　要：通过对某地埋管地源热泵系统制冷期长期连续监测,获取地埋侧和用户侧供、回水温度、流量及耗电量等数据,计算得到建筑日均小时负荷、机组日均能效比和系统日均能效比。结果表明,地埋侧和用户侧供、回水平均温差约为1.7℃,建筑日均小时负荷在80 kW左右,系统日均能效比平均值约为3.05,热泵机组未能达到理想工作状态,有待进一步改进。Based on a pipe cooling period of GSHP system long-term continuous monitoring, get supply and return water temperature, flow rate and power consumption data of underground side and user side, calculated daily hourly load, daily average unit building energy efficiency ratio and average system energy efficiency ratio. The results show that the supply and return water average temperature is about 1.7 degrees Celsius of underground side and user side, the average hourly load in the building is about 80 kW, the average daily energy efficiency ratio of the system is about 3.05, the heat pump unit can＇t achieve the ideal working state, needs to be further improved.
