目前建筑外墙热工节能设计计算中,对不同类型砖或砌块与砌筑砂浆构成的砌体的热阻和热惰性指标,缺少相应的计算参数。本文分析提出了以砌体的当量导热系数λe、平均蓄热系数Sm,作为计算块材砌体热阻及热惰性指标的两个热物理性能计算参数的依据和取值方法。 At present, in thermal energy design and calculation of building facades, the calculation of thermal resistance and thermal inertia of masonry composed of different types of bricks or blocks and masonry mortars lacks corresponding calculation parameters. In this paper, the equivalent heat conduction coefficient λe and the average heat storage coefficient Sm of masonry are proposed as the basis and calculation method for calculating the two thermophysical properties of brick masonry thermal resistance and thermal inertia.
