摘要
以某拟建地下水源热泵系统为例,针对地缘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,模拟了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。数值模拟结果表明,抽、灌井不同井间距对热泵系统夏季运行期间地下水热量运移过程影响显著,该方法为优化布设抽、灌井的合理间距提供了实现热泵系统良好运行的理论依据。
Taking the groundwater source heat pump（GWHP） system for an example,optimum arrangement of the working wells for the GWHP system is discussed in this paper.The ideal concepetual and mathematical model of the ＂double well＂ pumping-injecting are established.And the groundwater thermal transport processes in aquifer are simulated with the different intervals between pumping and injecting wells of the system summer running under the special groundwater-flow and heat source conditions.The numerical simulated results show that the thermal transport process in aquifer of the GWHP system summer running is significantly influenced by the various intervals between pumping and injecting wells.The study method can be adopted for the theoretical reference of these practical applications for the GWHP system.
