摘要
为了研究地下水渗流条件下土壤的蓄热性能及其影响因素,建立了地埋管换热器与土壤的准三维热渗耦合传热模型,通过方程离散和编程求解,研究了地下水渗流条件下渗流速度、U型管管内水流量等因素对土壤蓄热性能的影响规律,对比分析了连续蓄热模式和间歇蓄热模式对土壤蓄热性能的影响,研究结果可为土壤源热泵系统的蓄热运行方式提供参考。
For studying the thermal prope^y of underground heat exchangers under the influence of groundwater advection, a quasi-three-dimensional heat transfer between U-tube of underground heat exchanger and soil was modeled to simulate and analyze the influence of seepage velocity, U- tube water flow rate and intermittent operation. It provides a reference for the heat storage operation of the soil source heat pump system with composite heat source.
