再谈空调冷负荷的工程计算方法

Engineering Calculation Method of Air-Conditioning Cooling Load

传统的空调冷负荷计算方法需要大量详细的建筑信息。论文从实际出发,以冷负荷系数法为基础,分析了空调冷负荷的工程计算方法,指出了围护结构冷负荷、新风冷负荷等的影响因素,并针对北京、上海、广州等九个城市空调冷负荷的工程计算给出了修正系数。通过与实际工程的空调冷负荷进行对比分析,计算结果的误差仅为5%。

Traditional air-conditioning cooling load calculation method needs a lot of building information.Combining with engineering practice,based on cooling load coefficient method,this article analyzed a calculation method of air-condi-tioning cooling load,point out cooling load influence factors of enclosure structure and out air.And,this article gave the correction factor of cooling load for Beijing,Shanghai,Guangzhou and other nine cities.Comparative analysis with the re-sult of actual project,the deviation is only 5%.
