水源热泵开发对地下水动力场影响范围研究

Study on the Influence Range of Groundwater Hydrodynamic Field by the Development of Water Source Heat Pump

为分析研究水源热泵开发利用对地下水动力场的影响,选取安阳市金秋能源科创大厦地下水源热泵系统为实例工程,利用试验场观测数据建立地下水热耦合数值模型,对现状条件及长期开发利用条件下水源热泵开发利用对地下水动力场的影响进行分析预测。研究结果表明:在长期开发利用情况下,地下水的区域流场受抽灌水作用的影响范围较小,影响半径小于100 m。系统在多年运行的情况下,同期地下水流场基本相同,系统对地下水流场的影响范围比较稳定,没有进一步扩大的趋势。

In order to analyze and study the impact of development and utilization of water source heat pump on the groundwater hydrodynamic field,the underground water source heat pump system in Jinqiu Energy Kechuang Building in Anyang City was selected as an example project.The numerical model of groundwater thermal coupling was established by observation data from the test site.The current conditions and long-The impact of the development and utilization of groundwater heat pump on the groundwater hydrodynamic field is analyzed and predicted.Research indicates：Under the condition of long-term development and utilization,the influence of pumping water on the ground flow field of groundwater is small,and the influence radius is less than 100 m.When the system is running for many years,the groundwater flow field is basically the same in the same period,and the influence range of the system to the groundwater flow field is relatively stable,with no further expansion trend.
