摘要:
针对南京某湖水源热泵项目,该方法利用标准k-ε紊流模型对热泵系统运行时温排水的热扩散进行了三维数值模拟.重点研究了深度不均湖体中,排水口位置对温排水热扩散效应的影响.通过分析比较得出,排水位置对水平方向温排水热扩散影响较大,而对垂直方向热扩散影响比较微弱,高温区集中于排水口附近的小区域;在允许范围内将取水口设置于排水口上游可以降低"热短路"造成的影响;在排水口附近采取喷水或跌水措施,可以降低热泵系统尾水造成的湖体环境温升,研究结果为开式湖水源热泵系统设计提供参考.
Abstract:
Combined the experience of a lake water heat pump project in Nanjing,based on the standard k - ε turbulence model,the temperature field of the thermal discharge into the lake water body was computed. The effect of the thermal diffusion caused by the different locations of the outfall was mainly researched when the lake-depth is uneven. By comparison and analysis,there is a greater influence as to the horizontal distribution than vertical direction,and the high temperature zone concentrates on a small area near the outfall,the short-circuiting can be avoided when the water intake is located on the upstream the outfall,the influence on-environment can be reduced with some measures such as sprinkler system and waterfall. The results provide reference for lake-water heat pump systems design.
