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.
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 excessive to add peak-shaving heat source for water temperature is often low in winter.This paper introduced two operating modes of the peak-shaving surface water heat pump system,and deduced their operating cost models in heating period.With a calculation example,illuminated that the post-located system was superior and preferential on economy than fore-located one with 6.65 Yuan /m2 saving in the operating cost,which provided a beneficial instruction for the design.
