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。
The ideal concepetual and mathematical model of the "double well" pumping-injecting were established for the optimum arrangement of the working wells of groundwater source heat pump(GSHP) system.The groundwater thermal transport processes in aquifer were simulated with different intervals between pumping and injecting wells of the proposed GWHP system summer running under its special groundwater-flow and heat source conditions.The simulated results could be adopted for the theoretical reference of these practical applications.According to the numerical simulated results,the thermal transport in aquifer process of the GSHP system summer running was influenced by the various intervals between pumping and injecting wells significantly.The optimum interval between pumping and injecting wells should be between 50m and 60m under the regional hydro-geological conditions and running program.
