摘 要 :地表水源热泵具有重要节能环保与经济意义，但寒区冬季水温过低导致常需采用调峰型地表水源热泵系统。在介绍前置式系统和后置式系统两种形式的基础上，对调峰运行阶段的系统供热运行性能作了数学建模，并结合算例作了比较分析。结果表明后置式系统的运行性能与经济性均较好，每个供暖期可节省运行费6.65元/m2，这为系统方案的设计提供了有益的指导。 关键词 ：地表水源热泵，调峰型，前置式系统，后置式系统，供热，运行性能 Study On Heating Performance Of Peak-Shaving Surface Water Heat Pump System In Cold Area Qian Jianfeng, Ji Amin, Guo Yun, Zheng Dayu School of energy nbsp; Abstract : The surface water source heat pump plays a significant role on the energy conservation and environmental protection as well as the economy. But in the cold area it is the excessive to add peak-shaving heat source for water temperature is often low in winter. This paper introduces two operating modes of the peak-shaving surface water heat pump system, and deduces their operating cost models in heating period. With a calculation example, it illuminates that the post-located system is superior and preferential on economy than fore- located one with 6.65 Yuan /m2 saving in the operating cost, which providing a beneficial instruction for the design.
