针对地源热泵空调系统工作井优化布设问题,通过建立理想的“对井抽-灌”概念及数学模型,模拟拟建地下水源热泵系统特定水流及热源条件下抽水、回灌井不同间距夏季运行期间地下水热量运移过程,为抽、灌井合理间距确定等实际应用提供理论参考和依据。根据数值模拟结果,抽、灌井不同井间距对该热泵系统夏季运行期间地下水热量运移过程影响显著;场地区水文地质条件及运行方案下,热泵系统抽、灌井间距宜在50～60m间。
In order to optimize the layout of working wells in GSHP air-conditioning system, by simulating the concept of “pumping well-filling” and the mathematical model of groundwater source heat pump system, The groundwater heat transport process during summer operation provides a theoretical reference and basis for the practical application of pumping and well spacing reasonable calculation. According to the numerical simulation results, the pumping and well spacing of different wells have a significant influence on the heat transfer process of groundwater during the summer operation of the heat pump system. Under the hydrogeological conditions and operation schemes of the field, the pumping and well spacing of the heat pump system should be between 50 and 60m .
