摘要
以上海地区某工程为例,通过设置地温监测系统并对地温进行监测,根据监测结果和地源热泵系统运行情况,对地埋管地源系统运行期地温场的变化特征进行分析研究。结果表明:换热区地温变化与地源热泵系统的运行情况相关,呈现规律性的变化;经过一个运行年度,换热区的地温场能够基本恢复至原始状态;系统运行对换热区外围区域地温场的影响范围有限。研究成果可为浅层地温能的开发利用提供技术支持。
This paper reports the results of a soil-temperature monitoring project in the Shanghai area.A soil-temperature monitoring system was installed to monitor fluctuations in soil temperature.Measurements of temperature and of the operating status of the ground source heat pump system indicate that the soil temperature field in the ground-coupled heat pump system varied during the operating period.The results show that the soil temperature distribution in the heat exchanger is associated with the operation of the ground source heat pump（GSHP） system.After one year of operation,the soil temperature distribution in the heat exchanger returns essentially to the original condition.The running of a GSHP system cannot affect temperature changes outside the heat exchanger.The results should provide technical support for the development and utilization of shallow geothermal resources.
