摘要
为探究丹东市某工程地下水源热泵系统的实际应用效果及布井方式的合理性,采用COMSOL Multiphysics软件,建立三维水热耦合数值模型,对“两抽两灌”水源热泵系统进行为时一年的运行水温监测,并对实际应用中抽灌井的布置方式以及抽灌井间距是否存在含水层“热贯通”问题进行分析,将存在的问题与工程场地条件相结合。结果表明,采用“抽灌井平行布置”时,且抽灌井间距离为55 m时,发生“热贯通”的程度最轻,为丹东市水源热泵规划提供科学设计方法及参考依据。
In order to explore the practical application effect of the underground water source heat pump system of a project in Dandong city and the rationality of well spacing,a 3D hydro-thermal coupling numerical model was established with COMSOL Multiphysics software,and the operating water temperature of the “dual-pumping dual-irrigation” water source heat pump system was monitored for one year.In addition,the layout of the pumping and irrigation wells in practice and “thermal penetration”within the well spacing in the aquifer were analyzed,integrating the existing problems and site conditions.Results shows that if the “parallel layout of pumping and irrigation wells” is adopted and the spacing of pumping and irrigation wells is 55 m,“thermal penetration” is at the lowest level.This provides a scientific design method and reference for the water source heat pump planning of Dandong.
