中文摘要	为研究计量供热系统散热器在变流量工况下的动态特性,建立了散热器动态仿真模型。考虑了水流经散热器时的流动延迟,利用Lagrange法的思想,建立了流动过程、滞流过程、过渡过程的微元模型;利用Euler法建立了散热器集总模型;考虑散热量与室温的耦合关系,结合房间温度模型,进行联立求解。北京及天津2个小区采暖系统的测试结果与模拟结果吻合较好。该模型可用于变流量供热系统的节能分析。; Dynamic characteristics of radiators in heat metering systems were studied using a developed dynamic model for the radiators with various flow rates.The model considers the transport delay in the radiators and uses the Lagrange method to establish differential unit models for the continuous flow process,stagnant flow process and transition process,with a lumped model from the Euler perspective used to describe the radiator average temperatures.The system equations were solved coupling the heat dissipating capacity and room temperatures with sub-models.The experimental results in two district heating systems in Beijing and Tianjin agree well with the simulation data.Therefore,the model can be used for energy saving analysis.
