摘要
为了解重庆段长江水作为热泵冷热源的概况，对重庆段长江水温的横断面变化和时间变化进行了实测分析，并对江水的水质和水位变化进行了分析，得到长江水温在整个横断面基本恒定，而江水的夏季月平均温度在22～25℃，冬季月平均温度在11～16℃，水温日变化幅度不超过0．5℃。是一种具有良好品质的稳定的冷热源。而长江水作为水源热泵的冷热源，主要解决的水质问题是泥沙和悬浮物，在三峡库区形成后水位变化可达到30m，因此取水方式可考虑采用浮船取水方式。
The transectional distribution and temporal changes of Yangtze River water temperature are tested and analyzed in order to understand the general situation of Yangtze River water as the cooling and heating source for water source heat pumps in Chongqing, P. R. China. The water quality and water level variation are also analyzed. It is shown that Yangtze River water maintains a constant temperature across its transection. The monthly mean water temperature is 22 - 25 ℃ in summer and 11 - 16 ℃ in winter. Because daily water temperature variations do not exceed 0.5 ℃, Yangtze River water is a high quality cooling and heating source. The main water quality problems are sediment concentration and suspended load. Because the water level varies by 30m since the formation of the Three Gorges Reservoir, a floating pontoon water intake is preferable.
