热水供热枝状管网负荷承载力评估指标体系

Heat Load Carrying Capacity Assessment Index System of Hot-water Heat Supply Tree-shaped Network

随着人们对环境舒适度的要求越来越高,供热规模不断增长,对已有的管网的输配能力提出了更高的要求,负荷承载力的概念被引用到了热网的研究中。本文主要对枝状热水管网的负荷承载力评估问题进行了深入的研究,将承载力的概念引用到热网中进行定量研究中,分析了承载力概念的使用背景,定义了负荷承载力概念;利用层次分析的思想对承载力评估体系研究目标进行层级分解,建立评估指标体系;参照国家热力网相关标准、规范及北方地区热网运行实际目标值,协调经济性、技术性、节能性的要求确立评价标准值。

As people more and more strict requirement to the environmental comfort, heating has grown in size and distribution. The existing network was put higher request, the concept of the heat load bearing capacity is cited in the study of the heat supply network. This paper carry on research in-depth to the assessment of load bearing capacity of branched hot water pipe network. The concept of bearing capacity has been quoted to the study of the thermal network according to analyzing the background of carrying capacity, and it has defined the concept of heat load bearing capacity. Evaluation index system has been established basing on the target decomposition of carrying capacity assessment system by the idea of AHR Evaluation criteria value has been established with reference to national relevant standards, norms and the actual running data of thermal network in the northern region, coordinating economic, technical, energy conser- vation requirements.
