摘　　要：目前,燃煤锅炉是中国采暖的主要方式,也是造成空气污染的重要原因之一,核能可以替代燃煤锅炉,减少空气污染。同时,供暖过程中,更优化的运行模式一直是供热领域研究的课题之一,间歇供暖是一种常见的燃煤锅炉供暖模式。为了研究核能间歇供暖的可行性,以49-2池式供热堆为研究对象,基于MATLAB/Simulink软件平台,采用集总参数法建立池式反应堆供热系统仿真模型,利用DeST软件对房间热负荷进行计算建模,并利用试验数据对模型进行了验证。通过仿真,验证了核能间歇供暖运行模式的可行性和适用性。该模式减小了室内昼夜温差、提高了供热品质、降低了运行成本。At present,the winter heating system in northern China mainly relies on coal-fired boilers,which is one of the air pollution sources there.Nuclear energy can be considered to replace the traditional coal-fired boiler heating system and reduce air pollutant emissions.A more energy-efficient winter heating operation mode,such as intermittent heating which is a common mode,has always been one of the research topics in the heating research area.In order to study the feasibility of nuclear intermittent heating,based on the MATLAB/Simulink software platform and using DeST software,the thorough heating system models of the 49-2 pool type heating reactor were established by lumped parameter method and verified by experimental data.Through simulation,an intermittent heating operation mode that is suitable for the 49-2 pool type heating reactor was proposed.This mode reduces the indoor temperature difference between day and night,improves the heating quality and reduces the operation cost.
