| 摘 要： | 本文介绍了地下含水层储能的基本原理,建立了深井回灌式水源热泵系统含水层储能的数学模型并通过数值计算分别对6组不同井对距离条件下含水层采能区温度场的演化进行了量化研究,并对地温场的演化规律与井对距离之间的关系进行了理论分析,拟合出1个周期运行末期抽水温度相对变化值与井间距之间的关系.研究结果表明,抽、灌井对距离越大,抽水井温度变化越迟缓,且温度变幅越小,其原因是井对间距越大,渗流区水动力影响范围越大,抽、灌区等效渗流速度越小,回灌水向抽水井运动过程中散热(吸热)越充分.

| Abstract: | In this paper,the principle of aquifer thermal energy storage(ATES) was firstly introduced,and the mathematical model for ATES of water-source heat pump was established.Based on the model,numerical simulation in typical fine sand confined aquifer was presented for the changes of geo-temperature filed due to the energy extraction with six different well pair distances,and the relationships between the temperature changes of the last phase of operation and well pair distances were fitted.Meanwhile,theoretical... |
