摘要:
现阶段供热中存在着水力不平衡和运行能耗高等方面的问题,基于环路拓展的集中供热系统研究是降低供热系统能耗的重要手段之一。文章在对现有几种集中供热形式比较的基础上,结合分布式供热系统与水力分压器,提出了一种基于环路拓展的集中供热系统,在已有散热器用户回水管路上再串联一级散热器用户和一级地暖用户,对该供热系统环路的供热模型进行了分析,建立了供热系统三级串联的计算模型。结果表明:该供热系统稳定性好,调节方便,输配能耗低,在供热过程中可降低供热能耗;为实现舒适和节能要求,该供热系统宜采用三级或三级以下的串联环路。
Abstract:

There are many problems existing in the present heating system, such as hydraulic imbalance and high running energy consumption. The analysis of the district heating system based on loop expansion is an important means to reduce the energy consumption of heating systems. Through the comparison of several kinds of existing network heating forms, this article introduces the district heating system based on loop expansion, which combines the distributed heating system with hydraulic divider. In this system, we can connect a radiator user and a floor radiant heating user on the prior radiator user back water pipe. The heating system can reduce energy consumption with the advantages of good stability, convenient adjustment and low energy consumption. This article analyzes the heating model of the system loop and creates the series of three users computing model of this heating system.the loop expansion of the heating system should be three or less to achieve the comfort and energy saving vequirements.
