摘要
建筑节能现场测试是目前我国建筑热工与暖通空调领域研究的热点和难题,本文介绍了建筑围护结构传热系数的几种现场检测方法,对其检测依据、检测特点等进行了分析。环境因素对现场检测有重要的影响,通过试验对温差、辐射和风速等进行了分析,以期对围护结构的现场检测问题的解决提供帮助。
Recently, the field test of energy conservation in building becomes a focus and crux in the building thermal engineering and HVAC field in China. In this paper several field test methods of heat transfer coefficient of building envelope were reviewed, and their theory and feature were analyzed. Because the filed test is influenced much by environmental factors, the effect of temperature difference, radiation and the wind speed was analyzed based on the experiment to help achieving more precise field test of building energy conservation.
