阐述了轻质相变墙体的制备和热工性能分析,详细介绍了在西宁地区某轻钢结构被动式太阳房中的工程设计及应用情况,通过在无采暖设备情况下进行了室内环境温度的测试,评价采用轻质相变墙体的轻钢结构建筑作为被动式太阳房设计和使用的实验效果。实验结果显示轻质相变墙体应用于轻钢结构试验房,增大了建筑的蓄热能力和热惰性指标值,能有效对太阳热能进行储放,与普通轻钢结构试验房相比较,显著改善夜间室内热环境。
The preparation of light phase change wall and the analysis of its thermal performance are described. The engineering design and application of a light steel passive solar house in Xining area are introduced in detail. Through the analysis of the indoor ambient temperature without heating equipment Test and evaluate the light steel structure with light phase change wall as the experimental result of passive solar house design and use. The experimental results show that the lightweight phase change wall is applied to light steel structure test room, which increases the thermal storage capacity and thermal inertia index of the building, and can effectively store the solar thermal energy. Compared with the normal light steel structure test room, Significantly improve nighttime indoor thermal environment.
