摘要:
我国混凝土空心砌块的使用量巨大,如何有效利用EPS绝热材料,进一步提高其热工性能,扩大墙体自保温与隔热的能力以达到节能目标,对推动绿色建筑发展意义重大.本文分析了混凝土空心砌块内部热流渗透方式和路径,提出按传热方式不同区分传热路径,通过提高不同传热路径的热阻来提高砌块的整体热工性能.以此为基础,总结了几项改进空心砌块型式设计思路,同时设计了两组空心砌块并分析其热工性能.希望能抛砖引玉,以探索和设计出更为合理完善的砌块标准型式.
Abstract:
In view of the huge use of concrete hollow blocks in China, how to effectively use EPS heat-insulating materials to further improve its thermal performance and expand the self-insulation and thermal insulation capabilities of walls to achieve energy-saving goals is of great significance to the development of green buildings. In this paper, the method and path of heat flux infiltration in concrete hollow block are analyzed. It is proposed to distinguish heat transfer paths according to different heat transfer modes, and improve the overall thermal performance of the block by increasing the thermal resistance of different heat transfer paths. On this basis, several improved hollow block design ideas are summarized, and two groups of hollow blocks are designed and their thermal performance is analyzed.
