MetadataShow full item record
By establishing a mathematical model with the finite difference method, the three-dimensional temperature fields of a new type of asymmetrical hollow building blocks in an energy saving wall are solved in this paper. The three forms of heat resistance of air interlayer, conduction, natural convection, and radiation, are analyzed. To calculate the heat resistance of the air interlayer, an equivalent method is used in this paper. The heat resistance of the hollow building blocks in the energy saving wall is analyzed by electrical simulation, which is compared with experimental results. Compared to the traditional method, the calculation value of this method more accurately reflects the thermal characteristics of hollow building blocks. Results demonstrate that the heat resistance of air the interlayer increases as the thickness of the interlayer increases. However, when the interlayer thickness approaches 45mm, it tends to remain constant.
