【摘要】：以解决我国夏热冬冷地区太阳能在建筑中的应用问题为主要方向,提出一种新型太阳能相变蓄热(PCM)墙体技术:双流道-中间隔热型太阳能相变蓄热墙体系统。通过可对比热箱实验平台实验测试分析。研究得到:非采暖期时,实验间空气温度各天的平均值依次约为25.5、25.3、22.7℃,对比间空气温度各天的平均值依次约为25.4、25.1、22.5℃,相比差别不大,这表明该系统可有效防止建筑出现非采暖期过热的问题。同时,在冬季,该系统可利用太阳能获得较好的采暖效果,实验结果得到环境温度平均为2.7℃时,全天实验间空气温度平均为13.5℃,最高为30.6℃。在非采暖期和冬季工作模式下,相变板内外表面的温度趋于相近,表明本实验系统的相变板内填充的相变材料在厚度方向可做传热上的均匀性假设。
