摘要
散热器供暖二次网设计流量影响供热效果和供热成本,建立二次网供暖设计流量影响集中供热系统技术经济性的分析模型,通过定性分析和模拟分析得出了供暖系统二次网流量经济运行区域,改造案例项目不同循环流量供暖运行能耗的比较,通过北京既有项目供热系统改造情况进一步探讨二次网流量经济运行范围,研究成果初步应用于某新项目设计审查。
Secondary heating network flow rate affects radiator heating effect and heating cost. The analysis model is builted to analyze qualitatively, and simulation analyze technical and economic characteristics of the radiator heating system. In the heating operation cost composition, apart the fixed cost, the fuel cost is first main cost, the circulating pump electricit cost is second one. It is concluded that there is an economic operation area of secondary network flow rate for each radiator heating system.
