纺织厂空调冷负荷计算中的几个问题 【英文篇名】 Some issues in the cooling load calculation of air conditioning in textile mills 【作者中文名】 郭金芳; 罗万象; 【作者英文名】 By Guo Jinfang and Luo WanxiangChina Textile Industrial Engineering Institute; Beijing; China; 【作者单位】 中国纺织工业设计院; 【文献出处】 暖通空调, Hv 空调冷负荷; 围护结构; 热迁移系数; 【英文关键词】 textile mill; air conditioning cooling load; building envelope; thermal migration coefficient; 【摘要】 分别就锯齿形厂房和无窗厂房 ,对原围护结构冷负荷计算方法所得结果与冷负荷系数法计算结果进行了比较 ,二者偏差较大 ,建议采用冷负荷系数法计算围护结构冷负荷。通过计算分析 ,得知围护结构冷负荷在车间空调冷负荷中所占比例较小 ,其计算偏差的影响有限 ;机器散热引起的冷负荷是构成空调冷负荷的主要部分。对机器散热冷负荷计算中热迁移系数的取值问题进行了探讨。 【英文摘要】 Respectively aiming at saw tooth roofed workshops and windowless workshops, compares calculation results by original building envelope cooling load calculation method with those by the cooling load factor method, finding greater deviation, and recommends using the latter. Based on calculation and analyses, finds that the building envelope cooling load accounts for less proportion in workshop air conditioning cooling load, so the influence of calculation error is limited, and that the cooling load from mach...
