摘要
结合已施工的浅层地温能资源开发利用工程,在收集分析地质、水文地质和地源热泵项目资料基础上,建立了地源热泵监测系统,即地下水地源热泵系统监测站、地埋管地源热泵系统监测站和20个地源热泵系统监测点。通过布设温度传感器以及数据采集装置,对地源热泵系统进行动态监测,采用GPRS无线传输系统实现监测数据的远程传输。对所监测的数据进行分析,进而评估浅层地温能资源的开发利用对地质环境的影响程度,认为土壤温度场变化与深度存在一定的相关性,且地温的变化与系统的换热功率相关。
Combining with projects of development and utilization of shallow geothermal resources that have been carried out, based on the collection and analysis of geology, hydrogeology and ground-source heat pump project information, GSHP (ground source heat pump)monitoring systems including a groundwater GSHP monitoring station, a ground pipe GSHP monitoring station, as well as 20 GSHP monitoring points are set up. Through laying temperature sensors and data collection devices, we can realize dynamic monitoring, and adopt GPRS wireless transmission system to achieve long-distance transmission of monitoring data. Finally, according to analysis of monitoring data, the impact extents of the geological environment on the development and utilization of the shallow geothermal resources are assessed. It is concluded that the changes of soil temperature field are related to depth, and the changes of ground temperature are also associated with the system heat transfer power.
