在复合平壁瞬态导热传递函数模型的基础上,通过热平衡原理建立了围护结构瞬态导热的传递函数模型. 围护结构的传递函数由组成围护结构的各壁面的传递函数合成,为了保证合成过程的稳定性,提出了一种改进的优势特征根法. 实例计算效果良好.
Based on the model of transient heat transfer function of composite wall, the transfer function model of transient thermal conductivity of the envelope is established by the heat balance principle. The transfer function of the envelope is composed of the transfer functions of the walls that form the envelope. To ensure the stability of the synthesis process, an improved root characteristic method is proposed.
