摘　　要：针对邯郸某一项目的地表水源热泵设计中的取排水口形式设置问题,建立了二维湍流模型,采用数值模拟的方法,考虑到地表水源热泵系统与水环境之间的双向影响,研究了地表水源热泵排水口与河岸的角度和取排水口距离对温排水热扩散的影响,并计算了不同取排水形式下系统的COP(性能系数,Coefficient of Performance)。结果表明:随着排水与河岸角度的增大,取水口区域平均水温升高,同时地表水源热泵的COP呈下降趋势。综合比较水体热污染情况以及热泵系统性能得知:排水口与河岸的角度设置成50°~60°较为合适。For the form outlet of surface water heat pump( SWHP) in Handan, the two- dimensional turbulence model and numerical simulation is set up to study the effects of the outlet angle and the distance between intake and outlet on water heat pollution. Besides,this paper has taken consideration of the bidirectional influence between the SWHP and water environment, and calculate COP under different form of intake and outlet. According to the results, with the rising of the angle between outlet and bank, the temperature of intake increases,and COP decreases. If water heat pollution and the performanceof SWHP is taken into consideration, the ideal angle between outlet and bank is 50° ~ 60°.
