摘要
新型高性能气凝胶泡沫混凝土具有超高保温隔热性能,因其优良的防火性能、高耐久性能和低吸湿性能,目前已成为建筑保温隔热、节能减碳领域的热点研究方向之一。为探究气凝胶泡沫混凝土墙体在中国四个不同气候区下的节能性,本文通过建筑能耗模拟软件EnergyPlus,将气凝胶泡沫混凝土与传统泡沫混凝土应用于住宅建筑的外墙中,对建筑的全年、月度能耗进行对比分析。结果表明气凝胶泡沫混凝土能够节能2.1%-6%。研究结果可为气凝胶泡沫混凝土的推广与应用提供参考。
The aerogel foamed concrete has super high thermal insulation performance,excellent fire performance,high durability as well as low moisture absorption performance,thus it has become one of the most popular research directions in the field of building thermal insulation,energy saving and carbon reduction.In order to make a thorough inquiry of the energy-saving performance of aerogel-foamed concrete walls in four different typical climate zones in China,this paper applies aerogel foamed concrete and traditional foamed concrete to the exterior walls of residential buildings through the building energy consumption simulation software EnergyPlus,and makes a comparative analysis of the annual and monthly energy consumption of buildings.It is found that aerogel-foamed concrete can save energy by 2.1%-6%.The research results can provide a reference for the promotion and application of aerogel-foamed concrete.
