CL建筑体系热工性能测试及节能预测 分析研究.pdf

摘 要 气候变化与能源安全已经成为人类面临的最严峻的挑战。本文实地检测寒冷地 区外墙的热工性能，使用热箱法分别对 CL 建筑体系外墙，粉煤灰外墙和普通混凝 土外墙进行检测，利用 Origin 软件对测的结果进行了分析。试验证明在寒冷地区 CL 建筑体系比其他两种外墙有更好的节能效果。同时用 Ansys 12.0 软件对三种外 墙热传导进行了数值模拟，并与实测值进行了对比分析。按照 《民用建筑节能设计 标准》和 《民用建筑热工设计规范》计算出某住宅楼的建筑耗能。使用 EQUEST 建筑 耗能软件研究 CL 建筑体系的节能预测，分析研究 CL 建筑体系的屋顶传热系数，玻 璃类型，窗墙面积比等几个因素对全年耗电量的影响，建立了这几个主要因素对全 年电量的回归方程。并且分析研究 CL 建筑体系的玻璃类型，窗墙面积比与采暖季耗 能的关系。使用回归正交实验设计选取玻璃传热系数，窗墙面积比，屋面传热系数， 内墙传热系数几个因素对 CL 建筑体系的建筑能耗进行预测，得出多元线性回归方 程，并对回归方程进行验证，为建筑节能设计提供依据。 关键词：建筑节能；CL建筑体系；EQUEST； 热传导；数值模拟；回归正交实验设 计；能耗预测； Study on the thermal performance test and energy saving prediction research of CL building system Abstract Climate change and energy security have become the most serious challenges of human being. In this paper, we detected the thermal performance of exterior wall in cold areas on spot. Using hot box method, we detected the exterior walls of CL building system, fly ash and ordinary concrete wall, respectively. Then, the detected results were analyzed by using the software of Origin. The results proved that CL building system possessed better energy saving effect than the other two kind of exterior walls in cold areas. At the same time, we compared and analyzed the observed values and numerical simulated values of three kinds of exterior wall heat conduction, that the latter one was acquired by using the software Ansys 12.0. According to civil building energy saving design standard and civil building thermal design specification of a dwelling building, we calculated the energy consumption of some building. For analyzing several factors, such as heat transfer coefficient of roof, type of glass and window wall area, etc. that
