压力回灌技术在水源热泵系统中的应用研究

Application Research on Pressure Recharge in Underground-water Source Heat Pump System

摘要:

对水源热泵回灌技术的国内外应用情况进行了简单介绍，详细介绍了北京市顺义区某小区水源热泵压力回灌试验情况、工程应用情况及压力回灌应注意的事项。试验及工程应用表明，利用潜水泵扬程建立的压力回灌系统是可行的。理论分析认为，在使用过程中回灌井回灌量的降低有其必然性，而非完全因为固体颗粒物堵塞及化学堵塞等原因造成的。

Abstract:

The paper introduced the application of the recharge water source heat pump technology both at home and abroad and expatiated the experiment, engineering application and attention points about recharge water source heat pump system in Shunyi District, Beijing city. Test and engineering application showed that it was feasible to build the pressure recharge system by use of submersible pump lift. Theoretically, it is inevitable that the recharge yield reduced in the process of recharge, while not completely caused by the solid particles and chemical blockage.
