| 摘 要： | 通过建立地下水地源热泵系统试验场,运行热泵系统,并进行地下水温度连续监测,分析应用地下水地源热泵系统对地温场的影响。抽水井与回灌井之间以及回灌井附近的地下水温度随系统运行明显变化。系统运行后,回灌水体将以不规则边缘的透镜体贮存于含水层中,以回灌井为中心向外围扩展,水温最低或最高点位于含水层中部。粘性土相对隔水层的温度变化幅度、影响范围均小于含水层。由于热量的累积效应,即使是冷热负荷均衡的热泵系统,运行一个采暖、制冷周期后也将在热源井附近的抽、灌水含水层以及相邻的隔水层中形成冷量或热量的小范围聚积。

| Abstract: | Ground water source heat pump(GWHP) system is used in the test field.The influence of GWHP on regional geothermal field is analyzed based on the temperature of groundwater which is continuously monitored during the running course of the system.It is found that groundwater temperature of the area around pumping and recharge wells has a significant change in this process.Injection water will be stored in the aquifer with anomalous edge lens.The extreme values of temperature appear in the middle of the aquifer... |
