供暖状态下建筑热特性仿真分析
Building thermal characteristic simulation under heating condition
摘要：
对典型房间物理模型建立了动态数学模型，利用MATLAB/Simulink仿真方法，分析了室外温度、太阳辐射、风速和供水温度对供暖负荷和室内温度延迟特性的影响。结果显示：太阳辐射对建筑物的供暖负荷延迟影响较大；改变供水温度对供暖负荷的延迟规律几乎没有影响；对于窗户密封性能良好的建筑，风速增大对供暖负荷延迟影响不大。
Abstract：
Establishes the dynamic mathematic models for the physical model of a typical room.Through the MATLAB/Simulink simulation, analyses the effect of outdoor temperature, solar radiation, wind speed and supply water temperature on the delay characteristics of the heating load and indoor temperature. The results show that the solar radiation has great effect on the heating load delay. The change of supply water temperature has almost no effect on the delay characteristics of heating load. The increase of wind speed has little effect on the delay of heating load in the building with good sealing performance.
