摘要
本文就热反射外墙涂料或隔热外墙涂料的热工性能进行了分析研究,在此基础上得到了热反射外墙涂料的宏观热工参数,文中引入了传热系数修正值——即外墙采用热反射涂料后(=)的传热量与采用普通饰面的传热量比例——来表示热反射涂料对建筑热工性能的影响,并计算出了典型夏热冬冷与夏热冬暖地区热反射涂料的传热系数修正值。供同行在设计及研究工作中参考。
Both the theory and effectiveness of solar-reflective coating on exterior wall are investigated in the paper. The Thermo-characteristics of solar-reflective coating in building energy-saving are evaluated in the proportion of the heat transfer through the wall in solar-reflective coating with that without solar-reflective coating, the proportion is defined as modifying factor for heat transfer coefficient in this paper. The modifying factors are obtained based on the climate data of hot summer and warm winter area as well as hot summer and cold winter area.
