摘要
首次提出了用频率谱分析法分析墙体表面换热过程及推导墙体表面换热系数的实验方法．经实验和预测检验表明：该方法能够充分反映墙体表面换热过程，其结果是准确可靠的．为确定墙体表面换热系数找到了一种实用有效的方法。
The accurate method to determine wall surface heat transfer coefficient,which is an important parameter in calculation for building energy consumption of HVAC system,doesn't exist by now.This paper first presents an experimental procedure to analyze wall surface heat transfer process and derive wall surface heat transfer coefficient by frequency spectral analysis method.The verification by experimental and predicted results shows that this procedure can fully reflect wall surface heat transfer process and the result is accurate and reliable.A practical and effective approach has been found for determining wall surface heat transfer coefficient.
