摘要
室内风速的大小直接影响着室内空气与围护墙体之间的对流换热。本文运用有限单元法研究砌筑围护墙体的两种不同热阻值的砌块单元的热工性能,得出了在砌块孔洞中填充保温材料能够使热阻值提高的结论,找出了在不同风速环境下内部温度场分布变化规律,并指出热阻、风速与砌块热通量增量之间的关系。
The indoor wind speed direct impact on the convection heat transfer between indoor air and retaining wall. This paper uses finite element method to study thermal performance of two different thermal resistance block unit which used to masonry retaining wall, it is concluded that the hole in the block in filling heat preservation material can improve the thermal resistance of the conclusion, we find out the internal temperature field distribution change rule under different wind speed, and points out the relationship between thermal resistance, wind speed and block thermal throughput increment.
