摘要：由于长江上游的地表水富含大量的泥沙、藻类、微生物和悬移质，所以该地区长江水不能直接用于冷却蒸汽泵。本文将调查长江水作为热源汇的可能性，分析了长江重庆段的水温和水质，试验性地探究了水源热泵机组在不同的泥沙浓度、浊度、藻类物质条件下的运行状况，并提出了长江地区特殊地表水环境下，适应于节约能源的热泵的水质标准。实验结果表明，热泵的性能系数最大下降了3.73%，热量交换器中冷却水的污垢热阻在不同的水环境中可上升25.6%。当河流中泥沙浓度不超过100 g/m³，浊度不超过50 NTU，热泵的运行效率更好，这可以作为水源热泵的适宜水质标准之一。

Abstract: Due to the surface water in the upper reaches of Yangtze River in China containing large amounts of silt and algae, high content of microorganisms and suspended solids, the water in Yangtze River cannot be used for cooling a heat pump directly. In this paper, the possibility of using Yangtze River, which goes through Chongqing, a city in southwest China, as a heat source-sink was investigated. Water temperature and quality of the Yangtze River in the Chongqing area were analyzed and the performance of water source heat pump units in different sediment concentrations, turbidity and algae material conditions were tested experimentally, and the water quality standards, in particular surface water conditions, in the Yangtze River region that adapt to energy-efficient heat pumps were also proposed. The experimental results show that the coefficient of performance heat pump falls by 3.73% to the greatest extent, and the fouling resistance of cooling water in the heat exchanger increases up to 25.6% in different water conditions. When the sediment concentration and the turbidity in the river water are no more than 100 g/m³ and 50 NTU respectively, the performance of the heat pump is better, which can be used as a suitable river water quality standard for river water source heat pumps.
