基于ANSYS的节能环保多孔砖优化设计与热工分析
|
摘要
为了探究孔型、填充材料、基体材料对节能环保多孔砖热工性能的影响,运用ANSYS软件建立6种多孔砖模型及2种保温墙模型,通过改变多孔砖的填充材料、基体材料并分别进行热工分析。结果表明:孔型对多孔砖保温性能有着很大的影响,矩形孔砖的保温性能最优,其次依次是规则多边形砖、椭圆形砖和圆形孔砖;孔洞填充保温材料可以明显提高多孔砖的保温性能;随着多孔砖基体材料导热系数的减小,其热阻值逐渐增大,保温性能逐渐变优;通过对2种保温形式的淤泥保温墙体热工性能分析,发现以聚苯板作为墙体外保温材料的淤泥保温墙体能满足节能65%的规范要求。
In order to explore the influence of hole type,filling material and matrix material on the thermal performance of energy-saving and environmentally friendly porous bricks,this paper used ANSYS software to establish six kinds of porous brick models and two kinds of thermal insulation wall models,and conducted thermal analysis by changing the filling materials and matrix materials of porous bricks.The results show that the hole type has a great influence on the thermal insulation performance of the porous brick,the thermal insulation performance of the rectangular hole brick is the best among them,followed by the regular polygonal brick,the elliptical brick and the circular hole brick. Hole filling insulation material can significantly improve the insulation performance of porous brick; as the thermal conductivity of the porous brick matrix material decreases, the thermal resistance value increases gradually,and the thermal insulation performance gradually becomes better; through the analysis of thermal performance of the two kinds of insulation forms of the silt insulation wall,it is found that the silt insulation wall with the polystyrene board as the wall external insulation material can meet the specification requirements of energy saving of 65%.
