摘要
针对围护结构经济热阻传统计算方法的不足,提出用拉格朗日(Lagrange)未定乘数法推导出经济热阻和经济综合费用新的计算方法,这种计算方法不仅计算简便,而且考虑了不同气候条件、土建经济因素和使用经济因素,是一种更合理的方法。
Traditional calculation method is insufficient. A method of Lagrange undefined coefficient is used to calculate economical thermal resistance and economical overall cost. It not only considers different meteorological condition, construction economical factor, using economical factor but also simple and convenient.
