摘要
地下含水层能量利用已经成为一项新的和热泵技术发展紧密联系的技术,准确预测水源热泵工程周围含水层中的流场分布对能量的有效利用意义重大。通过分析含水层储能的一般特点,提出流贯通,分析流贯通和热贯通的相互作用、相互影响及对工程实际的意义,并基于地下水水热运移的基本原理,建立地下水流动数值模型,在此基础上对沈阳某场地水源热泵工程的运行进行流场及温度场的数值模拟分析,给出产生流贯通的依据,进而研究流贯通对热贯通的影响,并为该地区的地下水源热泵工程设计提供一定的参考。
The energy utilization of the aquifer has become a new technology, which links closely with the heat pump technology development, lf the flow distribution in the aquifer surrounding the Groundwater Source Heat Pump system （GSHP） can be predicted rightly, the great importance will be shown to the utilization of energy. By analyzing the general features of aquifer, a new concept of ＂the flow transfixion＂ was introduced, and the interaction between the flow transfixion and the heat transfixion and great signifwonce of the flow transfixion to projects were analyzed. A numerical model of groundwater flow based on the basic principles of water-heat transfer in the aquifer was established. Then the flow field and the temperature field of one Groundwater Source Heat Pump system （GSHP） in Shenyang city were numerically analyzed, and the basis of the flow transfixion was given. The impact of the flow transfixion on the heat transfixion was discussed, to some extent, which provides references for the projects design of GSHP in Shenyang regions.
