EnergyPlus与DeST的对比验证研究

Comparison of thermal model between EnergyPlus and DeST

在相同的内外扰量和空调运行方式下,采用EnergyPlus和DeST软件对同一建筑进行逐时冷热负荷计算,结果存在差异。分析发现主要原因是两个软件的热模型存在差异,说明通过围护结构表面的传热计算方法和相邻房间的邻室传热模型对负荷计算结果有重要影响。

Calculates hourly cooling and heating load of a building under the same conditions of the inner and outer interfering amount and air conditioning operation mode by EnergyPlus and DeST software,and finds the difference in results.After analysing,finds that the main cause is that there is a difference between thermal models of two software,which shows that there are the important influences of the calculation method of heat transfer through building envelope and the model of heat transfer from neighbouring rooms on the load calculation result.
