摘要
某地表水地源热泵项目位于晋江下游岸边,该河段在非汛期时呈现涨落双向流。在这种特殊的水文情况下,如何设计取排水口位置以避免热交换短路,以及尾排水对水环境的影响程度,是建设地表水地源热泵项目必须解决的两大问题。本文通过数值模拟分析指出:取水口位于排水口上游,相距大于150m时,不会出现热交换短路;尾排水对江水水体的影响有限,符合规范要求。
A surface water source heat pump project is located in the lower reaches of Jinjiang shore. the river shows fluctuations in the non flood season two- way flow. In this hydrological conditions,how to design the position of water intake and out fall to avoid heat exchange circuit,and the influence of tail water on water environment,is the two big problems must be solved in the construction of surface water source heat pump project. Through numerical simulation,this paper pointed out that the water intake outlet located upstream is larger than150 m,will not be short of heat exchange; the influence of tail water discharge to the river water body is limited,and meets the requirement of the standard.
