摘　　要：水温是重要的环境影响因子。江水源热泵可利用天然水体制冷或加热,具有广阔的应用前景,需进一步明确其对周边水温的影响,尤其是同排同取工况下江水源热泵系统的水温影响效应研究亟待开展。为此,该文以长江汉口滨江江水源热泵为例,建立了三维水动力和水温数值模型,分析了单个和多个江水源热泵能源站取排水对周边河道水温的影响,并提出了布置原则。研究结果表明:①单个江水源热泵取排水主要影响排水口附近区域水温,且水体温升分布有显著的垂向差异,水深增加,影响程度减小;②多组江水源热泵的水温叠加效应显著;③多组江水源热泵同时排放时,水温叠加效应随设置间距的增大而减弱。Water temperature is an important environmental influence.River water source heat pump can use natural water body for cooling and heating,which has broad application prospects.Its influence on the surrounding water temperature needs to be further clarified.Under the condition of the same row and the same take,the research on the influence effect of water temperature of the river water source heat pump system needs to be carried out urgently.Therefore,taking the Hankou riverside water source heat pump of the Yangtze River as an example,a three-dimensional numerical model of hydrodynamic power and water temperature was established,the influence of single and multiple river water source heat pump energy stations on the water temperature of surrounding rivers was analyzed,and the layout principle was proposed.The results show that:①The heat pump drainage of a single river source mainly affects the water temperature in the area near the drainage outlet.There is a significant vertical difference in the distribution of water temperature rise,and the degree of influence decreases with the increase of water depth.②The water temperature superposition effect of multiple groups of river source heat pumps is significant.③When multiple groups of river water source heat pumps are discharged at the same time,the water temperature superposition effect weakens with the increase of the setting interval.
