【摘要】 为提高集中供热系统的供热质量和供热经济性,提出一种集中供热系统热源运行负荷预测的方法。该方法考虑了热媒在管网输送过程中温度的衰减,将管段衰减度引入到基于图论理论所建立的供热管网模型中,建立热源运行负荷预测的数学模型。运用该模型可计算不同供热温度下的用户室内温度和供热管网中各节点的温度,对热源运行负荷进行预测,为供热系统的运行调节提供参考。更多还原

【Abstract】 To improve the heating quality and efficiency of the central heating system,a kind of load forecasting method was put forward. Attenuation degree which means temperature attenuation of heat medium in the process of transmission will be introduced to mathematical models of heating network which based on graph theory,to get the mathematical model of load forecasting at heat source. The user’s indoor temperature and the temperature of each node in the network under different temperature of supply water can be calculated using the model,and then to forecast the operating load at heat source,providing a reference for the operation and adjustment of the heating system.更多还原
