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:① The 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.② The water temperature superposition effect of multiple groups of river source heat pumps is significant.③ When 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.
