摘　　要：介绍了基于空间热网模型的采暖系统的计算机仿真程序 ,并运用该程序对低温地板辐射采暖和对流采暖两种系统进行计算机仿真 ,通过对一个采暖日内两种采暖方式下房间的采暖负荷、室内平均空气温度和维护结构内表面温度的动态分析和比较 ,证明了在维持房间相同热舒适度的情况下 ,低温地板辐射采暖系统的采暖负荷比对流采暖系统的采暖负荷小 ,具有节能性。A heating system simulation program based on space thermal network is introduced,and computer simulations of two different heating systems,low-temperature floor radiant heating system and convective heating system,are carried out with this program.Dynamic analysis of the heating load,inside temperature and interior surface temperatures under two different heating systems in a day are presented.The low-temperature floor radiant heating system is proved to be energy-efficient in comparison with the convective heating system.
