东北寒冷地区装配式农房热性能实测研究

Experimental Study on Thermal Performance of Prefabricated Farmhouses in Cold Regions of Northeast

双碳背景下,装配式轻钢结构建筑因其高效、经济、低碳的优势,成为当代乡村住宅建设发展的首要选择。以大连市复州城镇农房为例,通过对比分析装配式轻钢结构农房与当地传统青石砌筑结构农房的围护结构热工性能,从节能、环保效益角度分析装配式钢结构农房应用东北寒冷地区的适宜性。此外,实测结果表明装配式轻钢结构农房存在热稳定性差的问题,基于热稳定性影响因素分析发现提高外围护结构蓄热性能可有效提高轻质建筑的热稳定性和热舒适性。

Under the dual carbon background,prefabricated light steel structure buildings have become the primary choice for the development of contemporary rural residential construction due to their advantages of high efficiency,economy,and low-carbon.This article takes the rural houses in Fuzhou Town,Dalian City as an example to compare and analyze the thermal performance of the enclosure structure between prefabricated light steel structure rural houses and local traditional bluestone masonry structure rural houses.From the perspective of energy conservation and environmental protection benefits,the suitability of prefabricated steel structure rural houses for use in cold regions of Northeast China is analyzed.In addition,the actual test results indicate that prefabricated light steel structure rural houses have poor thermal stability.Based on the analysis of factors affecting thermal stability,it is found that improving the thermal storage performance of the outer enclosure structure can effectively improve the thermal stability and thermal comfort of lightweight buildings.
