摘要 通过实测，得到了长江上游流域不同地表水体的水温、水质特性基础数据。通过该流域某地表水地源热泵实际工程的运行测试，得到其夏季机组制冷性能系数为4.32，系统性能系数为3.02，表明地表水地源热泵系统在该流域应用具有节能效果。 关键词 长江上游流域 地表水地源热泵 水温 水质 性能系数 Investigation on applicability of surface water source heat pump systems to the area of Yangtze River upper reach By Liu Yong, Fu Xiangzhao, Wang Yong and Liu Yang Abstract Collects and analyses the measured data of water temperature and quality of different surface water bodies in the reaches. By measurement during operation of a surface water source heat pump system in the reaches, obtains that the coefficient of performance of the heat pump and the overall system is 4.32 and 3.02 respectively in summer. The data indicate that the surface water source heat pump system applied to the reaches has a good energy saving effect.
