重庆地区地表水地源热泵的应用及建议
Application and suggestion for surface water source heat pumps in Chongqing area
摘要：
结合三峡水库试运行期间长江、嘉陵江、乌江及典型内湖的水温和水质情况，分析了重庆地区应用地表水地源热泵的可行性。通过分析比较提出了地表水地源热泵系统取水水处理技术和水源热泵机组的选用原则。对典型工程的冬、夏季实测系统能效比分析表明，相对于传统空调方式，地表水地源热泵节能显著。针对水资源、工程应用和技术现状，提出了地表水地源热泵系统发展的若干建议。
Abstract：
On the basis of the temperatures and water quality of the Yangtze River, the Jialing River, the Wujiang River and the typical enclosed lakes during the test operation of the Three Gorges Reservoir, analyses the feasibility of application of surface water source heat pump to Chongqing area. Based on the analysis and comparison, puts forward the principle of selection for water treatment techniques and water source heat pump unit in surface water source heat pump system. The result from an analysis of measured energy efficiency ratio for typical projects shows that the surface water heat pumps save energy more than conventional air conditioning mode. Aimed at water resource, engineering application and actual technology, presents some suggestions for developing surface water source heat pumps.
