Numerical Study on Improving the Thermal Insulation Performance of Hollow Blocks by Optimizing the Holes Configuration
Publication: ICCREM 2016: BIM Application and Off-Site Construction
ABSTRACT
In this paper, dynamic thermal characteristics of concrete hollow block, which is commonly used in China, are studied numerically under periodic conditions using the climatic data of Harbin. The size of the hollow block is 390mm×190mm×190mm. Under the condition of the same hollow ratio, the holes configuration is varied by changing number of holes perpendicular and parallel to the heat flux in order to achieve the best performance. The number of holes perpendicular to the heat flux is varied from one to seven, and number of holes parallel to the heat flux is varied from one to four. The results show that the thermal performance of the hollow block is perfect with the increase of hole number perpendicular to the heat flux and the decrease of hole number parallel to the heat flux. The research results would assist in developing hollow blocks which could achieve a high thermal insulation performance and contribute to the energy saving in buildings.
