浅析热平衡措施对上海地区地源热泵系统换热区域温度的影响
Effect of heat balance measures on temperature in heat exchange area of ground-source heat pump systems in Shanghai
摘要：
基于上海地区浅层地热能项目多年的监测数据，分析了多个地源热泵项目运行多年后换热区域温度的变化特征，以及热平衡措施对换热区域温度的影响。分析结果表明：所监测地埋管地源热泵项目中，具备热平衡措施项目的地埋管换热区域温度基本稳定；不具备热平衡措施项目的地埋管换热区域温度基本上呈现升高趋势，出现了明显的热堆积现象。
Abstract：
Based on the monitoring data of shallow geothermal energy projects in Shanghai for many years, the change characteristics of the temperature field in the heat exchange area of the ground-source heat pump projects after many years of operation and the effect of thermal balance measures on the temperature field in the heat exchange area are analysed. The analysis results show that in the monitored buried pipe ground-source heat pump projects, the temperature in the buried pipe heat exchange area of the projects with heat balance measures is basically stable, that of the projects without heat balance measures basically shows an increasing trend, and obvious heat accumulation appears.
