利用长江水作热泵系统冷热源的技术分析

介绍了江水源热泵系统的形式，分析了长江重庆段的水温和水质情况。研究表明，长江水作为冷热源适于发展水源热泵技术，应优先选择壳管式直接利用热泵系统。此外，针对长江水泥沙含量高、夏季悬浮物和微生物数量多的问题，探讨了江水的净化处理、增强传热和除垢、热泵系统工况分析、取水方式以及江水二次利用等关键技术。

Technical Analysis on Using Yangtze River Water as Cold and Heat Sources of Heat Pump

The forms of river water source heat pump system were introduced and the water temperature and water quality of the Yangtze River in Chongqing area were analyzed. The investigation shows that used as cold and heat sources, the Yangtze River water is suited for developing water source heat pump technology and the shell-and-tube direct water source heat pump system is a feasible form. Furthermore, aimed to the high silt concentration and high content of suspended granules and microbes in the Yangtze River water in summer, the key technologies including the river water purifying treatment, enhancement of heat transfer and scale removal, behavior analysis of heat pump, intake water mode and recycled use of river water were discussed.
