【英文篇名】 Thoughts on System identification method for composition of z-transfer function of building envelope 【作者中文名】 张乐法; 【作者英文名】 By Chang Lo-Faw ★ ★Tai-Ning Agricultures Ltd.; Nanjing; China; 【作者单位】 台宁农工业开发有限公司; 【文献出处】 暖通空调, Hv z-传递函数; z-传递函数系数; 【英文关键词】 dynamic load; z-transfer function; z-transfer function coefficient; 【摘要】 质疑该文对得热与冷负荷两者关系的处理 ,认为文题不宜使用“动态负荷”一词。指出该文未能明确区分z 传递函数与z 传递函数系数 ,导致传递函数表达式的讹误 ,且传递函数系数计算阶数高达 1 0～ 1 2 ,ASHRAE手册及 30多年来工程实用领域 ,似无此高阶实例。 【英文摘要】 Questions the article in treating the relationship of heat gain with cooling load and argues that the term dynamic load should not appear in the title. Points out that article ignores the difference between the transfer function and transfer function coefficients, leading to a misrepresentation of the transfer function and that there has no example been found of calculating the coefficients to an order of ten to twelve in versions of ASHRAE handbooks and engineering practice in the past 30 years.
